Cloudflare changelogs

Workers, Access - You can now enable Access on a Worker or all Workers at once

Fri, 14 Aug 2026 00:00:00 GMT

You now have two new ways to protect your Workers with Cloudflare Access.

Protect an application across all its domains at once

Until now, if a Worker was reachable on a route, a Custom Domain, and a workers.dev URL, you had to manually add each one to an Access application and keep the list in sync whenever routes or domains changed.

Now, Access attaches the policy to the Worker itself, so every associated domain and preview URL stays protected even when its routes or domains change.

Protect all new and existing Workers by default

Make all Workers private by default, so every existing and newly created Worker requires sign-in before anyone can reach it.

If a specific Worker should remain publicly accessible, add a Worker-level bypass to exempt it.

Whether you protect a single application or all Workers at once, you can choose whether to protect preview deployments only or both previews and production, and control who can sign in by Cloudflare account membership, email address, or email domain.

For more advanced policy options, edit the policy in Zero Trust ↗.

View all of your Worker Access policies

You can view and manage all of your Access policies in the Access tab of the Workers & Pages section in the dashboard.

See who is accessing your Worker

When Access is enabled on your Worker, every authenticated request includes ctx.access. Call ctx.access.getIdentity() to get the user's email, name, and groups — no manual JWT validation required.

export default {
  async fetch(request, env, ctx) {
    if (!ctx.access) {
      return new Response("Access did not run", { status: 401 });
    }

    const identity = await ctx.access.getIdentity();
    return Response.json({ aud: ctx.access.aud, email: identity?.email });
  },
};

Test Access locally

You can now test Cloudflare Access locally with wrangler dev. Add a dev block to your wrangler.jsonc:

{
  "access": {
    "dev": {
      "aud": "my-app",
      "identity": { "email": "admin@example.com" }
    }
  }
}

Your Worker will receive this identity through ctx.access and ctx.access.getIdentity(), letting you test authenticated and unauthenticated flows without deploying. Remove the dev block to simulate unauthenticated requests.

API and programmatic access

You can also set up these policies through the Workers API instead of the dashboard.

Artifacts - Data localization support for Artifacts

Thu, 13 Aug 2026 00:00:00 GMT

Artifacts now supports jurisdictions, allowing you to select the European Union or the United States as the only location where repo data is stored and processed.

Select a jurisdiction when you create a namespace. Every repo in that namespace automatically uses the selected jurisdiction.

curl --request POST \
  "https://api.cloudflare.com/client/v4/accounts/$ACCOUNT_ID/artifacts/namespaces" \
  --header "Authorization: Bearer $CLOUDFLARE_API_TOKEN" \
  --header "Content-Type: application/json" \
  --data '{
    "namespace": "my-eu-namespace",
    "jurisdiction": "eu"
  }'

Jurisdictions cannot be changed after namespace creation. If you omit the jurisdiction, Artifacts creates an unrestricted namespace.

For supported jurisdictions and usage details, refer to Data localization.

Gateway - Detect and control software package downloads with package registry security

Thu, 13 Aug 2026 00:00:00 GMT

Cloudflare Gateway can now detect software package downloads and give you policy control over supply chain traffic. When a developer or CI/CD pipeline downloads a package through Gateway, the proxy identifies the registry protocol from the request URL and extracts the package ecosystem, name, version, and namespace. You can then write HTTP policies using pkg.* selectors to allow or block package downloads.

Supported ecosystems

Gateway detects package downloads for the following ecosystems:

Ecosystem	Namespace
npm	Scope (for example, `@babel`)
PyPI	--
RubyGems	--
Cargo	--
Go	Module path
Maven	Group ID
NuGet	--

Selectors

In the dashboard, select Package Ecosystem to access the package registry selectors. After selecting a single ecosystem, nested fields for package name, version, and namespace become available. Five pkg.* selectors are available for HTTP policies with the Allow and Block actions:

Selector	Description
`pkg.ecosystem`	The package ecosystem detected from the request URL.
`pkg.name`	The package name extracted from the download URL.
`pkg.version`	The package version, with support for ecosystem-aware comparison operators.
`pkg.namespace`	The package namespace, when the ecosystem supports one.
`pkg.purl`	The Package URL (PURL) ↗ derived from the detected coordinates. Available in the API only.

Detection is based on the registry protocol rather than the hostname, so it works the same way whether traffic goes to a public registry, a corporate proxy such as Artifactory or Nexus, or a self-hosted mirror.

Package registry security requires TLS decryption to be turned on.

For more information, refer to Package registry security.

Realtime - Control Realtime SFU DataChannel delivery

Thu, 13 Aug 2026 00:00:00 GMT

Cloudflare Realtime SFU is a WebRTC selective forwarding unit that runs on Cloudflare's global network. It forwards audio, video, and application data between WebRTC clients without requiring you to manage SFU infrastructure or regions.

DataChannels are WebRTC channels for application messages. A client publishes a named DataChannel to Realtime SFU, and the SFU forwards its messages to every client that subscribes to that channel. Use DataChannels for low-latency payloads such as chat messages, game state, sensor updates, and control events.

What changed

Realtime SFU DataChannels now support unordered and partially reliable delivery. DataChannels remain reliable and ordered by default, so existing channels keep their current behavior.

With ordered delivery, a delayed message can block later messages. For game state or sensor updates, recent data may be more useful than recovering an older message. Unordered delivery lets later messages proceed, while partial reliability limits retransmission attempts or delivery time.

Choose delivery behavior

Delivery settings answer two questions: whether newer messages can bypass a delayed message, and when the transport should stop retrying delivery.

Choose the policy that matches how long your payload remains useful:

Goal	Settings	Use when
Reliable, ordered delivery (default)	Omit `ordered`, `maxRetransmits`, and `maxPacketLifeTime`	Messages remain useful and must arrive in order
Reliable, unordered delivery	Set `ordered: false`; omit both retry fields	Messages remain useful, but later messages should not wait for earlier messages
No retries or ordering	Set `ordered: false` and `maxRetransmits: 0`	The application tolerates message loss and discards out-of-date updates
Limited retries	Set `maxRetransmits: <COUNT>`	Brief recovery is useful, but repeated retries are not
Time-bounded delivery	Set `maxPacketLifeTime: <MILLISECONDS>`	A message loses value after a known time window

ordered controls ordering independently from retries. maxRetransmits and maxPacketLifeTime are alternative retry budgets, so set at most one for each channel. Omit both for reliable delivery, whether ordered or unordered.

Apply the policy end to end

Realtime DataChannels use negotiated IDs, so browsers do not receive delivery settings from the remote peer. Apply the same settings when the publisher creates the local channel, each subscriber pulls the remote channel, and each client calls createDataChannel().

The following example configures unordered delivery with no retransmissions. It begins after you establish a DataChannel transport on both sessions and complete any required SDP exchange. Run the API requests from your backend with APP_ID, APP_TOKEN, PUBLISHER_SESSION_ID, and SUBSCRIBER_SESSION_ID set in your environment.

On the publisher session, create the local DataChannel:

curl --request POST \
	--url "https://rtc.live.cloudflare.com/v1/apps/$APP_ID/sessions/$PUBLISHER_SESSION_ID/datachannels/new" \
	--header "Authorization: Bearer $APP_TOKEN" \
	--header "Content-Type: application/json" \
	--data @- <<EOF
{
	"dataChannels": [
		{
			"location": "local",
			"dataChannelName": "player-state",
			"ordered": false,
			"maxRetransmits": 0
		}
	]
}
EOF

On each subscriber session, pull the remote DataChannel with the same delivery settings:

curl --request POST \
	--url "https://rtc.live.cloudflare.com/v1/apps/$APP_ID/sessions/$SUBSCRIBER_SESSION_ID/datachannels/new" \
	--header "Authorization: Bearer $APP_TOKEN" \
	--header "Content-Type: application/json" \
	--data @- <<EOF
{
	"dataChannels": [
		{
			"location": "remote",
			"sessionId": "$PUBLISHER_SESSION_ID",
			"dataChannelName": "player-state",
			"ordered": false,
			"maxRetransmits": 0
		}
	]
}
EOF

In the publisher and subscriber clients, create the negotiated browser DataChannel with the same settings. In this example, pc is the active RTCPeerConnection, and channelId is the ID returned by the corresponding API request:

const channel = pc.createDataChannel("player-state", {
	negotiated: true,
	id: channelId,
	ordered: false,
	maxRetransmits: 0,
});

SSL/TLS - Certificate Transparency Monitoring is now Generally Available

Thu, 13 Aug 2026 00:00:00 GMT

Certificate Transparency Monitoring is now generally available ↗ across all Cloudflare plans.

Alerts for certificates Cloudflare issues on your behalf (Universal SSL renewals, backup certificates, Advanced Certificate Manager, Total TLS) are now automatically filtered out. Alert emails are also clearer and more actionable, with structured certificate details and a direct link to manage CT Monitoring in the Cloudflare dashboard.

Learn more in the launch blog post ↗ or the CT Monitoring docs.

Email security - Block emails by content with blocked content rules

Wed, 12 Aug 2026 09:00:00 GMT

Cloudflare Email security now lets administrators write their own content-based blocking rules. A new Blocked content area under Policies & rules lets you define a plaintext string or a regular expression, choose whether to scan the message subject, body, or both, and automatically block any message that matches.

Create rules using either plaintext matches or regular expressions — useful for blocking targeted phishing campaigns, known-bad phrases, or content patterns unique to your organization.
Choose the search location for each rule: subject, body, or subject and body.
Use the built-in regular expression checker to validate your pattern against sample text before saving, so you can confirm the rule matches what you expect and avoid false positives.
Matching messages are marked with a malicious disposition and prevented from reaching users' inboxes.

Blocked content rules currently only support the block action.

This feature is available for the following Email security packages:

Enterprise
Enterprise + PhishGuard

To get started, refer to Blocked content.

Cloudflare One, Access - Independent MFA supports FIDO2 for infrastructure applications

Wed, 12 Aug 2026 00:00:00 GMT

Infrastructure applications support independent multi-factor authentication (MFA) with FIDO2 keys. You can allow ssh_fido2_key, piv_key, or both in application-level and policy-level MFA settings.

Users enroll FIDO2 keys through the App Launcher and connect with the generated SSH identity. FIDO2 keys for SSH are separate from browser-based WebAuthn security keys and Personal Identity Verification (PIV) keys.

For setup instructions, refer to Enroll a FIDO2 key for infrastructure apps and Configure MFA for infrastructure applications.

Gateway, Cloudflare One - MCP protocol detection and AI Security dashboard

Wed, 12 Aug 2026 00:00:00 GMT

Cloudflare Gateway now automatically detects Model Context Protocol (MCP) ↗ traffic flowing through your network. MCP is the standard protocol used by AI agents to connect to external tools and data sources. Gateway identifies MCP requests by inspecting protocol-specific headers and payload characteristics.

MCP policy selector

A new Is MCP selector (experimental.is_mcp) is available in HTTP policies. Use this selector to build Gateway rules that allow, block, or isolate MCP traffic.

This selector is currently in beta and may change before general availability.

For example, the following policy blocks MCP traffic that does not arrive through an approved MCP portal:

Selector	Operator	Value	Logic	Action
Is MCP	is	True	And	Block
Traffic Source	is not	MCP portal

AI security report

A new AI security report dashboard under Insights & Logs > Dashboards provides visibility into MCP usage across your organization. The dashboard includes:

Total MCP request volume, unique users, and unique MCP servers
A timeseries chart of unique MCP servers observed over time
A summary of Gateway policies that target MCP traffic

For more information, refer to HTTP policies.

Gateway, Cloudflare One - Traffic Source selector in Gateway policies

Wed, 12 Aug 2026 00:00:00 GMT

Gateway HTTP and Network policies now include a Traffic Source selector that identifies how traffic reaches Cloudflare. This allows administrators to write policies that target specific on-ramp methods - for example, applying different rules to traffic arriving via the Cloudflare One Client compared to traffic routed through an MCP portal or a proxy endpoint.

Available traffic source values

UI name	API value	Description
Device client	`device_client`	Traffic from the Cloudflare One Client (WARP)
Mesh	`mesh`	Traffic from a Cloudflare Mesh connector
Cloudflare WAN	`cloudflare_wan`	Traffic from Cloudflare WAN (Magic WAN)
Clientless RDP	`clientless_rdp`	Traffic from a clientless RDP session
Proxy endpoint	`proxy_endpoint`	Traffic from a proxy endpoint (PAC file)
Clientless Browser Isolation	`agentless_biso`	Traffic from clientless Browser Isolation
MCP portal	`mcp_portal`	Traffic from an MCP portal

The selector uses the net.onramp.type API field in both HTTP and Network policies.

UI name	API example
Traffic Source	`net.onramp.type == "device_client"`

Browser Isolation selector

A Browser Isolation selector is also available in Network and HTTP policies. This selector identifies whether the current session is running inside Remote Browser Isolation, allowing administrators to apply different policy behavior to isolated traffic.

UI name	API example
Browser Isolation	`net.is_isolated == true`

For more information, refer to HTTP policies and Network policies.

Pages - Pages now skips superseded queued builds

Tue, 11 Aug 2026 00:00:00 GMT

Pages now automatically skips a queued build when a newer build for the same project, branch, and deployment target is also queued.

Support - New Cloudflare Status page

Tue, 11 Aug 2026 00:00:00 GMT

The Cloudflare Status page at www.cloudflarestatus.com ↗ has been rebuilt. It is available at the same address, and every previously documented Status API ↗ endpoint remains supported, so existing bookmarks, integrations, and monitoring continue to work.

Notifications that fire even when Cloudflare is down

The status page now has its own notification system, delivered independently of Cloudflare infrastructure. You can subscribe by email, webhook, Slack, Discord, or Google Chat.

The Maintenance Notification and Incident Alerts in Cloudflare Notifications remain supported, and deliver to the destinations already configured on your account.

Markdown for AI agents

Every page on the status page returns Markdown when requested with an Accept: text/markdown header, so agents can read the current status without parsing HTML:

curl -H "Accept: text/markdown" https://www.cloudflarestatus.com/locations

Separate feeds for incidents and maintenance

Incidents and maintenance are published as separate feeds, each available in RSS and Atom, so you can subscribe to one without the other:

https://www.cloudflarestatus.com/api/v3/incidents.rss
https://www.cloudflarestatus.com/api/v3/incidents.atom
https://www.cloudflarestatus.com/api/v3/maintenance.rss
https://www.cloudflarestatus.com/api/v3/maintenance.atom

For more information, refer to Cloudflare Status.

Cloudflare Tunnel, Cloudflare Tunnel for SASE, Cloudflare Mesh, Gateway, Cloudflare One - Hostname routing is now generally available, with a new public IP range for initial resolved IPs

Tue, 11 Aug 2026 00:00:00 GMT

Hostname routing ↗ is now generally available. Instead of managing static IP lists and routes, you can route traffic by hostname across multiple Cloudflare One connectors:

Cloudflare Tunnel: route a private hostname (for example, wiki.internal.local) to a private application behind your tunnel, or a public hostname (for example, bank.example.com) to egress through a specific tunnel and anchor traffic to a dedicated exit node.
Cloudflare Mesh: attract a private or public hostname's traffic to a Mesh node.

Alongside GA, the default IPv4 range used for initial resolved IPs (also called token IPs) is changing from a Carrier-Grade NAT (CGNAT) range to a public Cloudflare-owned range:

IPv4: 172.64.128.0/20
IPv6: 2606:4700:0cf1:4000::/64

This is the default range. You can configure a custom initial resolved IP range for IPv4 if it conflicts with your existing network.

Why this is changing: Starting with Chrome 142 ↗, Local Network Access (LNA) restrictions block background requests to CGNAT addresses (100.64.0.0/10), which included the previous initial resolved IP default (100.80.0.0/16). LNA is implemented at the Chromium engine level, so it affects all Chromium-based browsers (for example, Microsoft Edge, Brave, and Opera), not only Google Chrome. This could silently break hostname-based Gateway features for users of these browsers, and required Chrome Enterprise policy workarounds. The new default range is public Cloudflare address space, so it is not affected by this restriction.

What is affected: Initial resolved IPs are used by several features that associate a DNS query with the network connection that follows it:

Private and public hostname routing for Cloudflare Tunnel
Hostname routes for Cloudflare Mesh
Access private applications on non-HTTPS ports
Egress policy host selectors (Domain, Host, Application, and Content Categories)

You can check your account's current range, or configure a custom range, at any time from Zero Trust > Team & Resources > Devices > Device profiles, or using the Initial Resolved IP Subnet API.

For full instructions, refer to Configure initial resolved IPs. The IPv6 range (2606:4700:0cf1:4000::/64) is unchanged and is not affected by this restriction.

If you were relying on a Chrome Enterprise policy workaround (such as LocalNetworkAccessRestrictionsTemporaryOptOut) while your account was still on the legacy CGNAT-based range, refer to Google Chrome restricts access to private hostnames for next steps.

WAF - WAF Release - 2026-08-11

Cloudflare Managed Ruleset	N/A	vBulletin - Code Injection - Invalid image format - CVE:CVE-2019-17132 - Beta	Log	Block	This rule is merged into the original rule "vBulletin - Code Injection - Invalid image format - CVE:CVE-2019-17132" (ID: )

Cloudflare One Client - Cloudflare One Client for Windows (version 2026.6.905.0)

Mon, 10 Aug 2026 20:28:46 GMT

A new GA release for the Windows Cloudflare One Client is now available on the stable releases downloads page.

This hotfix addresses an uncommon and intermittent case on Windows devices where the device is unable to reconnect after the device is woken from sleep.

Cloudflare Tunnel, Cloudflare Tunnel for SASE - Stream live logs from Cloudflare Tunnel in the dashboard

Mon, 10 Aug 2026 00:00:00 GMT

Real-time Tunnel log streaming is now available in the Cloudflare dashboard under Networking > Tunnels. This brings the same live debugging capability previously only available in the Cloudflare One dashboard, including multi-connector aggregated streaming for high-availability deployments.

In the tunnel detail view, a new Live logs tab lets you:

Stream logs from single or multiple connectors — In highly available deployments with multiple cloudflared replicas, logs from all connectors are merged into a single stream grouped by hostname, making it easy to identify which host machine produced each log entry.
Filter by log level, event type, and HTTP method — Narrow the stream to only the events you care about (HTTP, TCP, UDP, or cloudflared internal), at any log level.

Go to Tunnels ↗

For more information, refer to Monitor tunnels and Tunnel log streams.

Turnstile - Turnstile Spin is now generally available

Mon, 10 Aug 2026 00:00:00 GMT

Turnstile Spin is now generally available with three setup paths for creating a Turnstile widget and wiring canonical server-side siteverify into your existing backend. Start in the dashboard, with Wrangler, or from your AI coding agent. All three paths create the same widget. You can complete the integration by hand or have your agent embed the widget, wire siteverify, and validate it.

Server-side verification

Turnstile setup has two parts: embed the widget in your frontend, then call siteverify from your backend. Without the second part, the widget appears on the page but does not protect the request.

The skill includes insertion snippets for Next.js (App Router and Pages Router), Astro, SvelteKit, Hugo, and vanilla HTML. For other frameworks, the agent proposes a generic pattern and asks you to confirm it first.
The Turnstile dashboard flags existing widgets with no matching siteverify traffic. Select Fix with Spin to copy a prompt that guides your agent through wiring siteverify into your backend.
Before finishing, the agent runs a real Turnstile token through your protected endpoint, checks that it passes, then replays the token to confirm the endpoint rejects it on the second try. If a check fails, the agent stops and shows you where.

Run Spin

You can run Spin three ways:

In the Turnstile dashboard, select Set up with Spin, enter your domains, then select Set up. Spin creates the widget and returns the sitekey, secret, and a prompt for your agent.
From the Wrangler CLI, run wrangler turnstile widget create. Wrangler prints the sitekey and secret. You wire the frontend and siteverify by hand.
From your AI coding agent, paste the Spin prompt into Claude Code, Cursor, Codex, OpenCode, or GitHub Copilot Chat. Your agent fetches the skill, creates the widget, then embeds it and wires siteverify.

To get started, refer to the Turnstile Spin documentation.

AI Gateway, Workers AI - Workers AI and AI Gateway unify model access and billing

Fri, 07 Aug 2026 00:00:00 GMT

Workers AI and AI Gateway now provide a unified path for accessing models and managing inference traffic. Use the same AI binding and REST API to call models hosted on Workers AI or by supported third-party providers, with AI Gateway providing observability, logging, caching, security, and billing controls.

Unified entrypoints and observability

The AI binding supports both Workers AI and third-party models through env.AI.run(). The REST API provides shared /ai/ endpoints with Cloudflare authentication across providers.

Route a Workers AI request through AI Gateway by specifying a gateway ID. Use default to automatically create a gateway on the first authenticated request, or specify an existing gateway to separate applications and workloads:

const response = await env.AI.run(
	"@cf/zai-org/glm-5.2",
	{
		messages: [{ role: "user", content: "What is the capital of France?" }],
	},
	{
		gateway: { id: "default" },
	},
);

const response = await env.AI.run(
	"@cf/zai-org/glm-5.2",
	{
		messages: [{ role: "user", content: "What is the capital of France?" }],
	},
	{
		gateway: { id: "default" },
	},
);

Requests routed through AI Gateway can be logged and included in analytics for request volume, errors, latency, token usage, and costs. You can also configure controls such as caching, rate limiting, and request retries on the gateway.

Unified billing and higher rate limits

You can now use prepaid AI Gateway credits to pay for Workers AI inference. This provides one credit balance for Workers AI and supported third-party model providers. To use credits for Workers AI, set the gateway's Workers AI billing setting to Unified billing. Workers AI requests routed through that gateway deduct from your credit balance in real time.

Prepaid credits also provide access to the following Workers AI frontier models without requiring the Workers Paid plan. Each frontier Workers AI model has a rate limit of 50 requests per minute per account, per model when billed with AI Gateway credits, compared to 20 requests per minute through standard Workers AI billing:

These limits are designed for typical agentic and coding workloads, where requests to frontier models can take longer to complete.

For details, refer to Workers AI limits, Workers AI pricing, Unified Billing, and the AI Gateway model catalog.

Hyperdrive - MySQL support in Hyperdrive is now generally available

Fri, 07 Aug 2026 00:00:00 GMT

Support for MySQL in Hyperdrive is now generally available. You can connect to any MySQL database from your Workers using Hyperdrive.

Hyperdrive makes your regional, MySQL databases fast when connecting from Cloudflare Workers. It eliminates unnecessary network roundtrips during connection setup, pools database connections globally, and can cache query results to provide the fastest possible response times.

You can connect using your existing drivers, ORMs, and query builders with Hyperdrive's secure credentials, with no code changes required. MySQL support is available at the same pricing as Postgres.

import { createConnection } from "mysql2/promise";

export default {
	async fetch(request, env, ctx) {
		const connection = await createConnection({
			host: env.HYPERDRIVE.host,
			user: env.HYPERDRIVE.user,
			password: env.HYPERDRIVE.password,
			database: env.HYPERDRIVE.database,
			port: env.HYPERDRIVE.port,
			disableEval: true, // Required for Workers compatibility
		});

		const [results, fields] = await connection.query("SHOW tables;");

		ctx.waitUntil(connection.end());

		return new Response(JSON.stringify({ results, fields }), {
			headers: {
				"Content-Type": "application/json",
				"Access-Control-Allow-Origin": "*",
			},
		});
	},
};

import { createConnection } from "mysql2/promise";

export interface Env {
	HYPERDRIVE: Hyperdrive;
}

export default {
	async fetch(request, env, ctx): Promise<Response> {
		const connection = await createConnection({
			host: env.HYPERDRIVE.host,
			user: env.HYPERDRIVE.user,
			password: env.HYPERDRIVE.password,
			database: env.HYPERDRIVE.database,
			port: env.HYPERDRIVE.port,
			disableEval: true, // Required for Workers compatibility
		});

		const [results, fields] = await connection.query("SHOW tables;");

		ctx.waitUntil(connection.end());

		return new Response(JSON.stringify({ results, fields }), {
			headers: {
				"Content-Type": "application/json",
				"Access-Control-Allow-Origin": "*",
			},
		});
	},
} satisfies ExportedHandler<Env>;

Cloudflare Mesh, Cloudflare One - Container image for Cloudflare Mesh

Fri, 07 Aug 2026 00:00:00 GMT

Cloudflare Mesh nodes can now run as Docker containers. The cloudflare/mesh ↗ image is available on Docker Hub for Docker Compose, Kubernetes, and any OCI-compatible runtime — no host-level package installation required.

The image supports amd64 and arm64 architectures and includes built-in source NAT so return traffic routes correctly without VPC route table changes.

Deployment patterns

Docker Compose — add a cloudflare-mesh service to your compose.yaml and connect your entire stack to a private network.
Kubernetes StatefulSet — deploy a standalone Mesh node with persistent registration state.
Kubernetes sidecar — add the Mesh image as a sidecar container in a Pod to connect an application to Cloudflare without application changes.
CI/CD — pull the image in a pipeline step, join the Mesh, run integration tests against private infrastructure, and tear down. The node disappears when the container exits.

For high availability, run multiple replicas with the same Mesh node token. Cloudflare operates replicas in active-passive mode with automatic failover.

Go to Mesh ↗

For setup steps, runtime configuration, and deployment examples, refer to Run Mesh in Docker / Kubernetes.

Radar - AS-level connectivity and upstream providers on Cloudflare Radar

Fri, 07 Aug 2026 00:00:00 GMT

Radar expands its Routing section ↗ with two widgets on AS pages, such as AS13335 ↗, that describe how a network reaches the rest of the Internet: the paths it takes toward the Tier-1 ↗ networks, and the mix of direct upstreams carrying its routes. Both are derived from RouteViews ↗ RIB snapshots, unioned across selected collectors.

AS-level connectivity

The AS-level connectivity graph aggregates the BGP paths an AS uses to reach the Tier-1 networks, unioned across all the prefixes it announces, as observed by selected RouteViews collectors. It reads from left to right, starting at the queried AS and ending at the Tier-1 networks, and each node is labeled with its AS number, country, and organization name. Tier-1 nodes are marked so they stand apart from the intermediate networks that lead to them.

By default, the graph shows the network's direct connections to Tier-1 networks plus the indirect paths, which keeps the view readable. A Show full paths toggle expands it to every observed path, including transit through Tier-1 networks the AS already connects to. An IP version selector switches between IPv4 and IPv6, because the paths reaching Tier-1 networks may differ between the two address families.

This is the AS-level counterpart to the Real-time connectivity graph on prefix pages, such as the one for 1.1.1.0/24 ↗. Instead of covering a single prefix, it covers the union of paths for all prefixes an AS announces, which makes it a fast way to read a network's transit hierarchy: which providers it depends on, how many hops separate it from the core, and whether its paths to the core are diverse or concentrated. For more information on the prefix-level graph, refer to BGP real-time routes.

Upstream providers

The Upstream providers widget tracks the share of an AS's observed paths carried by each of its direct upstream networks over time, drawn as a stacked area chart. Up to 10 upstreams appear as their own series and the remaining ones are grouped into Other. Transit changes such as adding a provider, dropping one, or moving traffic between them appear as movement between bands rather than as a single aggregate number. As with the connectivity graph, an IP version selector switches between IPv4 and IPv6.

API endpoints

The data behind both widgets is also available through two new endpoints on the BGP API:

/bgp/routes/paths/{asn} — Returns the ordered AS path segments an AS uses to reach the Tier-1 networks, each with its observed path count, peer count, and contributing collectors, alongside the name and country of every ASN in the response. Pass collector to scope the result to a single RouteViews collector.
/bgp/routes/upstreams/{asn}/timeseries — Returns the share of an AS's observed paths carried by each direct upstream over time. Use limit to control how many upstreams come back as separate series before the rest are grouped into an OTHER series, and ipVersion to select the address family.

Visit the AS13335 routing page ↗ to explore both widgets, or swap in any other AS number.

Radar - Radar Researcher beta and WebMCP support now available

Fri, 07 Aug 2026 00:00:00 GMT

Cloudflare Radar now includes Radar Researcher ↗, a beta AI-powered assistant for exploring Internet trends and traffic data in plain language.

Sandbox SDK - Sandbox SDK 1.0 preview on @next

Fri, 07 Aug 2026 00:00:00 GMT

Sandbox SDK 1.0 is available to preview under the npm @next tag. For existing applications, the current stable package remains published on the 0.12.x line.

Sandbox SDK first shipped to provide a rich library for running untrusted and agent-driven work on Cloudflare Containers. Since then, both Sandbox and Containers have matured. This preview is a thinner SDK built on a richer Cloudflare Containers foundation.

npm i @cloudflare/sandbox@next

yarn add @cloudflare/sandbox@next

pnpm add @cloudflare/sandbox@next

bun add @cloudflare/sandbox@next

What this preview is

A single execution interface — sandbox.exec() takes an argument list, returns when the process starts, and gives you a handle for output, logs, waits, and signals. Both short commands and long-running services use the same API.
Removed session execution — the SDK no longer maintains shell state between executions. Each launch is independent. Pass cwd and env when you need them, or put multi-step shell syntax in one explicit shell command.
RPC as the only transport — the SDK talks to the container exclusively over RPC. Remove SANDBOX_TRANSPORT, transport on getSandbox(), and setTransport().
Improved PTY and terminal interface — interactive PTYs use createTerminal / connect, not the older session-shaped helpers.
Code interpreter as an extension — configure the code interpreter on your Sandbox subclass so you only ship what you need.

Start new projects on @next. Migrate existing apps when you can so you are ready when 1.0 becomes stable. Deploy the Worker package and container image from the same @next line.

Coding agents: install Cloudflare Skills ↗ (Agent setup). Use sandbox-next for @next (recommended for new projects), sandbox-stable for the current stable package, and sandbox-migrate-to-next when you are ready to port. Stable-package deprecated-API cleanup is in the 2026 deprecation guide.

The main Sandbox documentation still describes today's stable package. Preview docs:

The self-deployed Sandbox bridge is not currently part of this preview. We are working on bringing it in line with the latest code. Until then, use the stable bridge with the matching stable package and container image.

Timeline for 1.0

Further Cloudflare Containers features will let us keep reducing the size of the Sandbox SDK. We aim to ship Sandbox SDK 1.0 once those are in. In the meantime we continue to support and maintain the 1.0 preview (@next) alongside the current stable release.

WAF - WAF Release - 2026-08-07

Fri, 07 Aug 2026 00:00:00 GMT

This release updates WordPress XSS rule metadata in the Cloudflare Managed Ruleset and Cloudflare Free Ruleset to identify XSS2Shell (CVE-2026-64638). It also disables the Command Injection - Obfuscation rule.

Key Findings

CVE-2026-64638: A pre-authentication reflected cross-site scripting vulnerability affecting the WordPress login screen. Exploitation requires social engineering and explicit interaction by the target user. Under additional conditions, it may be escalated to remote code execution.

Impact

The WordPress changes update rule metadata only; detection behavior and actions remain unchanged.

Ruleset	Legacy Rule ID	Description	Previous Action	New Action	Comments
Cloudflare Managed Ruleset	N/A	Wordpress - XSS - CVE:CVE-2026-64638	Block	N/A	Rule metadata description refined. Detection unchanged.
Cloudflare Free Ruleset	N/A	Wordpress - XSS - CVE:CVE-2026-64638	Block	N/A	Rule metadata description refined. Detection unchanged.
Cloudflare Managed Ruleset	N/A	Command Injection - Obfuscation	Block	Disabled	Detection logic has been deprecated

AI Search - AI Search makes it easier to build a search engine for your data

Thu, 06 Aug 2026 00:00:00 GMT

AI Search gets you from a data source to a working search endpoint quickly. This release adds what you need to put that endpoint in front of real users: your own domain, authentication, and one endpoint across several instances. It also adds crawling for sites without a complete sitemap, so your index covers everything you want it to find.

Each of the following is a new option. The previous behavior is still the default, so nothing changes until you change it.

Serve search from your own domain

A public endpoint is a URL that a site or app can query directly, with no authentication in front of it. By default that URL is a generated hostname on search.ai.cloudflare.com. You can now serve the same endpoint from a custom domain, a hostname in a zone that you own:

https://search.example.com/search

Restrict who can query your content

Once your endpoint is on your own domain, you can put Cloudflare Access in front of it. For example, you usually want to give /mcp to specific agents rather than to anyone who finds the URL. Agents authenticate with an Access service token, and people who open the endpoint in a browser sign in through your identity provider.

Search several instances from one URL

A namespace can expose its own public endpoint with /search, /chat/completions, and /mcp paths that fan out across the instances you choose:

curl https://ns-<NAMESPACE_ENDPOINT_ID>.search.ai.cloudflare.com/search \
  --header "Content-Type: application/json" \
  --data '{
    "messages": [{ "content": "How do I configure AI Search?", "role": "user" }],
    "ai_search_options": { "instance_ids": ["docs", "support"] }
  }'

Index your sites without a sitemap

Website data sources support a new discover parse type. It starts at the source URL and collects pages from both your sitemaps and the links it finds while crawling:

curl -X POST "https://api.cloudflare.com/client/v4/accounts/<ACCOUNT_ID>/ai-search/instances" \
  -H "Authorization: Bearer <API_TOKEN>" \
  -H "Content-Type: application/json" \
  -d '{
    "id": "my-ai-search",
    "type": "web-crawler",
    "source": "example.com",
    "source_params": {
      "web_crawler": {
        "parse_type": "discover",
        "discover_options": { "source": "links", "limit": 5000, "depth": 3 }
      }
    }
  }'

To learn more, refer to the AI Search documentation.

Browser Run - Introducing Kitesurf, an agent-first browser on Browser Run

Thu, 06 Aug 2026 00:00:00 GMT

Kitesurf is Cloudflare's new stateless, highly scalable browser that runs entirely on top of Workers and is designed for AI agents. It is available for free while in beta.

Compared to Chromium, Kitesurf uses 3–7× less CPU and memory for common agentic tasks like screenshots and HTML extraction, so you can run more sessions and scale better for bursty, AI-driven workloads.

Your existing clients already work. To opt in, add the browser=kitesurf parameter to any Browser Run CDP or Quick Action endpoint:

curl -X POST 'https://api.cloudflare.com/client/v4/accounts/<ACCOUNT_ID>/browser-run/screenshot?browser=kitesurf' \
  -H 'Authorization: Bearer <API_TOKEN>' \
  -H 'Content-Type: application/json' \
  -d '{
    "url": "https://example.com"
  }' \
  --output "screenshot.png"

You can also explore Kitesurf without writing any code in the public playground ↗.

For more information, refer to the Kitesurf documentation and the blog announcement ↗.

AI Gateway - Track AI spend and catch anomalous usage with User Insights

Wed, 05 Aug 2026 20:00:00 GMT

AI Gateway now includes User Insights, a dashboard that gives you two things at once: clear visibility into how much your organization spends on AI, and a security signal that surfaces users whose usage suddenly looks abnormal. It works on the traffic already flowing through your gateway, so there is no additional setup.

On the spend side, User Insights shows organization-wide totals for cost, requests, tokens, and adoption, and lets you drill into an individual user to see their spend, top models and providers, cache hit rate, and more. To attribute usage to individual users, add a user identifier with custom metadata or put your gateway behind Cloudflare Access.

On the security side, User Insights baselines each user's normal usage from their 95th percentile (p95) session cost over the last 30 days, then flags sessions that exceed both that baseline and an organization-level threshold. A sudden jump above a user's own pattern is often the first sign of a compromised credential or a misbehaving agent, so you can investigate before it shows up on your bill.

User Insights is available to all AI Gateway customers at no additional cost.

AI Gateway, Access - Identity-aware controls are now available in AI Gateway

Wed, 05 Aug 2026 00:00:00 GMT

AI Gateway now integrates with Cloudflare Access, giving you two new capabilities:

Protect your gateway endpoint. Put your AI Gateway behind Access so you can set policies that control who is allowed to call a specific gateway's endpoint.
Identity-aware controls. When traffic reaches AI Gateway through an Access-protected custom domain, AI Gateway can use the authenticated user's Access identity in logs, analytics, routing, and spend controls.

With identity-aware controls, you can set spend limits by authenticated user, control which gateways different users can access, filter logs by user, and build policies without passing user IDs from the client application. AI Gateway adds the verified Access user ID to request metadata as cf.user_id.

For setup instructions, refer to Cloudflare Access.

Cloudflare Fundamentals - Improved publisher verification details on OAuth consent screens

Wed, 05 Aug 2026 00:00:00 GMT

OAuth consent screens now display a shield icon with explanatory text beneath the consent screen title. Each shield icon indicates who owns the application and whether its domain ownership is verified.

Green filled shield: Cloudflare owns and manages the application.
Blue outlined shield: A third-party application with verified ownership of its domain.
Amber filled shield: A third-party application without verified ownership of a domain.

Domain verification only confirms that the application owner controls the displayed domain.

For more information, refer to Authorizing an application.

Agents, Workers - Agent traces for Think, Flue, and AI SDK instrumented by Agents SDK

Tue, 04 Aug 2026 00:00:00 GMT

Agent tracing is now available for applications built with the Agents SDK. Traces show each agent turn alongside model calls, tool runs, approvals, token usage, and Workers runtime operations.

Turn on Workers tracing in your Wrangler configuration:

{
  "$schema": "./node_modules/wrangler/config-schema.json",
  "observability": {
    "traces": {
      "enabled": true
    }
  }
}

[observability.traces]
enabled = true

Think and Flue applications emit agent traces automatically. For direct AI SDK calls, wrap the AI SDK namespace once. wrapAISDK() supports AI SDK v6 and v7. This AI SDK v7 example also supplies the agent identity:

import * as ai from "ai";
import { wrapAISDK } from "agents/observability/ai";

const tracedAI = wrapAISDK(ai);

await tracedAI.generateText({
	model,
	prompt: "Find an available appointment",
	runtimeContext: {
		agentId: "booking-agent-production",
		conversationId: "conversation-123",
	},
	telemetry: {
		functionId: "booking-agent",
		includeRuntimeContext: {
			agentId: true,
			conversationId: true,
		},
	},
});

import * as ai from "ai";
import { wrapAISDK } from "agents/observability/ai";

const tracedAI = wrapAISDK(ai);

await tracedAI.generateText({
	model,
	prompt: "Find an available appointment",
	runtimeContext: {
		agentId: "booking-agent-production",
		conversationId: "conversation-123",
	},
	telemetry: {
		functionId: "booking-agent",
		includeRuntimeContext: {
			agentId: true,
			conversationId: true,
		},
	},
});

Message and tool payload recording is off by default. Turn it on only when the payloads are safe to store:

const tracedAI = wrapAISDK(ai, {
	storeMessages: true,
	storeTools: true,
});

const tracedAI = wrapAISDK(ai, {
	storeMessages: true,
	storeTools: true,
});

Open the Agents tab ↗ in the Cloudflare dashboard to inspect sessions, replay conversations, and view trace waterfalls. For advanced setup, privacy controls, and trace structure, refer to Agent tracing.

Artifacts, Workflows - Build and deploy Artifacts repos on every push

Tue, 04 Aug 2026 00:00:00 GMT

You can now run your CI/CD pipeline on your Artifacts repo by defining a CI Workflow with the CI SDK ↗, automatically triggered on Artifacts push events.

This allows you to:

Automatically build and deploy application code stored in Artifacts.
Run linting, type checking, tests, and other checks on every push.
Reuse dependencies when the lockfile (i.e. pnpm-lock.yaml) has not changed.
Stop deployment when a check or build fails.
Restrict API token access to the deployment step.
Deploy the output to a Worker or a Workers for Platforms User Worker.

Define your CI steps with @cloudflare/ci. Each ci.runner() spins up an isolated sandbox, and the cache option reuses installed dependencies across each sandboxed step in your CI job.

Point cache.inputs at your lockfile (i.e. pnpm-lock.yaml, bun.lock), and the install step only runs again when that lockfile changes:

src/index.jsjs

const deps = await ci.runner({
	name: "install",
	command: "bun install --frozen-lockfile",
	cache: { inputs: ["package.json", "bun.lock"] },
});

await Promise.all([
	deps.runner({ name: "lint", command: "bun run lint" }),
	deps.runner({ name: "test", command: "bun run test" }),
	deps.runner({ name: "typecheck", command: "bun run typecheck" }),
	deps.runner({ name: "build", command: "bun run build" }),
]);

await deps.runner({ name: "deploy", command: "bun wrangler deploy" });

src/index.tsts

const deps = await ci.runner({
	name: "install",
	command: "bun install --frozen-lockfile",
	cache: { inputs: ["package.json", "bun.lock"] },
});

await Promise.all([
	deps.runner({ name: "lint", command: "bun run lint" }),
	deps.runner({ name: "test", command: "bun run test" }),
	deps.runner({ name: "typecheck", command: "bun run typecheck" }),
	deps.runner({ name: "build", command: "bun run build" }),
]);

await deps.runner({ name: "deploy", command: "bun wrangler deploy" });

To start the Workflow automatically after each push, add a cf.artifacts.repo.pushed trigger to your Wrangler configuration:

{
	"triggers": {
		"events": [
			{
				"type": "cf.artifacts.repo.pushed",
				"filter": {
					"namespace": "CI",
					"repoName": "my-repo",
				},
				"target": {
					"scriptName": "my-ci-worker",
					"workflowName": "ci-workflow",
				},
			},
		],
	},
}

[[triggers.events]]
type = "cf.artifacts.repo.pushed"

  [triggers.events.filter]
  namespace = "CI"
  repoName = "my-repo"

  [triggers.events.target]
  scriptName = "my-ci-worker"
  workflowName = "ci-workflow"

To learn more, refer to Build and deploy Artifacts repos.

Cloudflare Fundamentals - Create Free accounts from the dashboard

Tue, 04 Aug 2026 00:00:00 GMT

You can now create standalone Free accounts directly from the Cloudflare dashboard using the new Create Account button. This feature is currently available to all users.

When creating a Free account:

You can create up to 5 Free accounts.
Your user account must have at least 7 days of tenure to be eligible.
The account is created immediately and ready to use.

To create a Free account, go to the Cloudflare dashboard ↗ and select Create Account from either the account switcher in the top left (where your account name appears) or from the Accounts page.

Limitations

This feature can only be used to create a Cloudflare Free account. To create an Enterprise Account under your existing contract, please contact Cloudflare Support.
All users can create a Cloudflare Free account, however, Enterprises wish to restrict this action to only Super Administrators. We will deliver this improvement in a future release.

Next steps

After creating your Free account, you can:

Add a payment method to enable additional Cloudflare products and services.
Update billing information to manage payment methods, billing address, or tax IDs.
Review how Cloudflare billing works to understand the billing lifecycle and charge types.
Assign accounts to an Enterprise Organization to centrally manage multiple accounts from a single dashboard.

Vectorize - Vectorize indexes now support up to 20 million vectors

Tue, 04 Aug 2026 00:00:00 GMT

You can now store up to 20 million vectors in a single Vectorize index, doubling the previous limit of 10 million vectors. This enables larger-scale semantic search, recommendation systems, and retrieval-augmented generation (RAG) applications without splitting data across multiple indexes.

Vectorize continues to support indexes with up to 1,536 dimensions per vector at 32-bit precision. Refer to the Vectorize limits documentation for complete details.

WAF - WAF Release - 2026-08-04

Tue, 04 Aug 2026 00:00:00 GMT

This release introduces new rules and updates Microsoft SharePoint RCE alongside enhanced SSRF cloud protection rule actions.

Workers - AI agents can debug Workers with local tracing

Tue, 04 Aug 2026 00:00:00 GMT

wrangler dev and vite dev automatically capture structured OpenTelemetry traces and correlated console logs during local Worker invocations.

Debug with AI agents

When the tooling detects an AI agent session, it prints a terminal hint pointing to the Local Explorer API at /cdn-cgi/explorer/api. The API serves an OpenAPI schema and exposes a read-only observability query endpoint for discovering telemetry, querying traces and logs, and inspecting binding state.

The agent can identify the exact failing operation, fix the code, rerun the request, and verify the result. This debug loop requires no deployment or temporary logs.

Inspect traces in Local Explorer

Humans can inspect the same traces and correlated console logs in the Local Explorer browser UI. Each trace shows spans, timing, attributes, and errors.

Automatic spans cover handler calls, outbound fetch() calls, and binding calls. Custom spans appear alongside these automatic spans.

For more details, refer to the Local Explorer documentation.

Workers - Node.js compatibility is now enabled by default

Tue, 04 Aug 2026 00:00:00 GMT

Workers now enable the nodejs_compat and nodejs_compat_v2 compatibility flags by default for compatibility dates of 2026-08-04 or later. These flags are not used for these compatibility dates because the compatibility date enables the same behavior.

This means all Node.js built-in APIs supported by the Workers runtime are available by default, including node:crypto, node:buffer, node:stream, node:net, node:dns, node:fs, node:http, and more. npm packages that depend on these APIs will work without additional configuration.

Workers using an earlier compatibility date are not affected. They can still opt in by adding nodejs_compat to compatibility_flags.

New projects do not need to add either flag. Existing projects can update their compatibility date without removing them. Wrangler, Miniflare, the Cloudflare Vite plugin, and Vitest Pool Workers ignore these redundant flags when starting the runtime.

To turn off Node.js compatibility completely, remove any nodejs_compat and nodejs_compat_v2 flags. Then add both of the following flags:

{
  "$schema": "./node_modules/wrangler/config-schema.json",
  // Set this to today's date
  "compatibility_date": "2026-08-14",
  "compatibility_flags": [
    "no_nodejs_compat",
    "no_nodejs_compat_v2"
  ]
}

# Set this to today's date
compatibility_date = "2026-08-14"
compatibility_flags = ["no_nodejs_compat", "no_nodejs_compat_v2"]

For more information, refer to the Node.js compatibility documentation.

Access - Control authorization cookies for multi-domain Access applications

Mon, 03 Aug 2026 00:00:00 GMT

Cloudflare Access administrators can now control whether a self-hosted application preemptively sets authorization cookies across its public hostnames.

Previously, Access automatically used eager redirects for applications with five or fewer hostnames. Applications with more than five hostnames received cookies as users visited each hostname. Administrators can now choose either behavior, regardless of the number of hostnames.

The new Eager redirect cookie setting is turned on by default for new applications. After a user signs in, Access redirects the browser through each hostname and sets a CF_Authorization cookie. This supports applications that need to make requests across hostnames before the user visits each one.

For applications with many hostnames, the redirect chain can cause sign-in loops in some browsers. Turn off the setting to issue the cookie only when a user visits each hostname.

To configure the setting, refer to Authorization cookie.

Agents, Workers - Preview: @cloudflare/computer agent runtime

Mon, 03 Aug 2026 00:00:00 GMT

We're releasing an early preview of @cloudflare/computer ↗, an open-source agent runtime that gives every agent its own computer. The runtime dynamically orchestrates between fast, efficient isolates and full Linux containers, so the agent always runs on the right compute primitive for the task at hand.

@cloudflare/computer provides a virtual filesystem backed by SQLite, which you can populate from cloud storage, source control, or any files you choose. Agents can read, write, and edit files, run shell commands, and interact with Git repositories. All operations are gated, audited, and observed.

Install the package via npm:

npm install @cloudflare/computer

Instantiate a Workspace inside any Durable Object to give your agent a filesystem and execution runtime:

import { Workspace } from "@cloudflare/computer";

export class Agent {
	workspace = new Workspace({
		storage: this.ctx.storage,
	});
}

Several execution backends are included or you can write your own:

Isolate runtime — fast, horizontally scalable execution via just-bash and Dynamic Workers, ideal for file manipulation and data processing.
Container runtime — full Linux environment via Cloudflare Containers, mounted through FUSE, for tasks that need native binaries, package managers, or a complete userland.

The AI SDK-compatible toolkit provides common agent tools (read, write, edit, ls, exec) and guides the model to choose the appropriate backend for each task.

For more examples, including a step-by-step tutorial, visit the @cloudflare/computer repository ↗.

Read the announcement blog post for more details: Your agent needs a computer, not a container ↗.

Pipelines - Billing is now enabled for Pipelines

Mon, 03 Aug 2026 00:00:00 GMT

Billing is now enabled for Cloudflare Pipelines on non-enterprise accounts. Pipelines usage beyond the included free tier will appear on your next invoice.

Pipelines charges based on two usage dimensions. Ingress into a Pipeline stream remains free regardless of volume:

SQL transforms: $0.04 / GB for stateless transforms (filter, reshape, unnest, cast, compute).
Sinks (egress): $0.03 / GB for JSON output, $0.06 / GB for Parquet or Iceberg output.

Workers Paid plans include 50 GB / month for both SQL transforms and sinks. Standard R2 storage and operations charges apply for data written to R2 buckets, and R2 Data Catalog charges apply when writing to Iceberg tables.

For example, a pipeline that ingests 500 GB of event data per month, uses a SQL transform to filter and reshape it, and writes 300 GB to an R2 Data Catalog Iceberg table would be billed as follows:

Dimension	Usage	Included	Billable	Cost
Streams	500 GB	Unlimited	0 GB	$0.00
SQL transforms	500 GB	50 GB	450 GB	$18.00
Sinks (Iceberg)	300 GB	50 GB	250 GB	$15.00
Total				$33.00

For full pricing details and billing examples, refer to Pipelines pricing.

R2, R2 Data Catalog - Billing is now enabled for R2 Data Catalog

Mon, 03 Aug 2026 00:00:00 GMT

Billing is now enabled for R2 Data Catalog on non-enterprise accounts. R2 Data Catalog usage beyond the included free tier will appear on your next invoice.

R2 Data Catalog charges based on two dimensions, in addition to standard R2 storage and operations:

Catalog operations: $9.00 / million operations for metadata requests such as creating tables, reading table metadata, and updating table properties.
Compaction: $0.005 / GB processed and $2.00 / million objects processed. These charges only apply when automatic compaction is turned on for a table.

Each dimension includes a monthly free tier: 1 million catalog operations, 10 GB of compaction data processed, and 1 million compaction objects processed.

For example, a single Iceberg table with 50 GB of data, 500,000 catalog operations per month, and compaction turned on that processes 20 GB across 200,000 files would be billed as follows:

Dimension	Usage	Included	Billable	Cost
Catalog operations	500,000	1,000,000	0	$0.00
Compaction (data processed)	20 GB	10 GB	10 GB	$0.05
Compaction (objects)	200,000	1,000,000	0	$0.00
Total (Data Catalog)				$0.05

Standard R2 storage charges ($0.015 / GB-month) apply separately for the 50 GB of data stored.

For full pricing details and billing examples, refer to R2 Data Catalog pricing.

R2 SQL - Billing is now enabled for R2 SQL

Mon, 03 Aug 2026 00:00:00 GMT

Billing is now enabled for R2 SQL on non-enterprise accounts. R2 SQL usage beyond the included free tier will appear on your next invoice.

R2 SQL charges based on a single dimension:

Data scanned: $0.0025 / GB ($2.50 / TB) of compressed data read from R2 to execute your query.

All plans include 10 GB of data scanned per month. Each query is billed for a minimum of 10 MB of data scanned. R2 SQL pricing is additive to standard R2 storage and operations and R2 Data Catalog charges. R2 does not charge for egress, so there is no additional data transfer cost.

For example, a user who stores 500 GB of Parquet data in R2 Data Catalog and runs queries that scan a total of 50 GB of compressed data during the month would be billed as follows:

Dimension	Usage	Included	Billable	Cost
R2 storage	500 GB-month	10 GB-month	490 GB-month	$7.35
R2 SQL (data scanned)	50 GB	10 GB	40 GB	$0.10
Total				$7.45

For full pricing details and billing examples, refer to R2 SQL pricing.

Workers - Python and JavaScript Workers can now call each other via RPC

Mon, 03 Aug 2026 00:00:00 GMT

You can now call methods between Python and JavaScript Workers using Workers RPC. This works through Service bindings without extra dependencies, schema definitions, or serialization code.

Cross-language RPC calls behave like ordinary function calls. Exceptions propagate to the call site. You can pass structured cloneable types ↗ as parameters or return values, and Pyodide Foreign Function Interface (FFI) automatically converts types between languages.

Call a TypeScript Worker from Python

Define a method in a TypeScript Worker:

index.jsjs

import { WorkerEntrypoint } from "cloudflare:workers";

export class RpcService extends WorkerEntrypoint {
	async add(a, b) {
		return a + b;
	}
}

index.tsts

import { WorkerEntrypoint } from "cloudflare:workers";

export class RpcService extends WorkerEntrypoint {
	async add(a: number, b: number): Promise<number> {
		return a + b;
	}
}

Call it from a Python Worker through a Service binding:

from workers import Response, WorkerEntrypoint

class Default(WorkerEntrypoint):
	async def fetch(self, request):
		rpc = self.env.RPC
		result = await rpc.add(42, 144)
		return Response.json({"result": result})

Configure the Service binding in the Python Worker's Wrangler configuration:

{
	"services": [
		{
			"binding": "RPC",
			"service": "ts-rpc-server",
			"entrypoint": "RpcService"
		}
	]
}

[[services]]
binding = "RPC"
service = "ts-rpc-server"
entrypoint = "RpcService"

Call a Python Worker from JavaScript

Define a method in a Python Worker:

from workers import WorkerEntrypoint

class Default(WorkerEntrypoint):
	async def highlight_code(self, code: str, language: str) -> dict:
		from pygments.formatters import HtmlFormatter
		from pygments import highlight
		from pygments.lexers import get_lexer_by_name

		lexer = get_lexer_by_name(language, stripall=True)
		formatter = HtmlFormatter(linenos=True, cssclass="highlight", style="monokai")
		highlighted_html = highlight(code, lexer, formatter)
		css = formatter.get_style_defs(".highlight")

		return {
			"html": highlighted_html,
			"css": css
		}

Call it from a JavaScript Worker through a Service binding:

index.jsjs

export default {
	async fetch(request, env) {
		const rpc = env.PYTHON_RPC;
		const result = await rpc.highlight_code("print(42)", "python");
		return Response.json(result);
	},
};

index.tsts

export default {
	async fetch(request, env) {
		const rpc = env.PYTHON_RPC;
		const result = await rpc.highlight_code("print(42)", "python");
		return Response.json(result);
	},
};

Configure the Service binding in the JavaScript Worker's Wrangler configuration:

{
	"services": [
		{
			"binding": "PYTHON_RPC",
			"service": "py-rpc-server"
		}
	]
}

[[services]]
binding = "PYTHON_RPC"
service = "py-rpc-server"

Cloudflare One Client - Cloudflare One Client for Windows (version 2026.7.1210.1)

Fri, 31 Jul 2026 13:55:39 GMT

A new Beta release for the Windows Cloudflare One Client is now available on the beta releases downloads page.

This beta release includes the following changes and improvements:

Improved connection reliability: the client now swaps protocol order after repeated connectivity-check failures, which helps when HTTP/3 is blocked after the QUIC handshake.
Fixed issue where a certificate error could be incorrectly displayed right after the connection is established.
A DNS search domain parsing failure no longer prevents connection.
Fixed a MASQUE issue where the tunnel could stall while uploading at a high rate.
Fixed being unable to switch organizations when the client was stuck in the "Device not in organization" state.
Fixed the Home Screen dropdown popup not anchoring correctly.
Fixed a crash during dialog dismissal.
Increased tolerance for configurations with a large number of local domain fallback resolver IPs, so DNS resolution behaves correctly even when more fallback resolvers are configured than recommended.
Fixed a networking issue where IPv6 multicast routes were being assigned to the WARP tunnel interface.
Fixed fatal errors on UI load on Windows 10.
Fixed a crash during Windows notification initialization.
Made the Windows domain-joined posture check more reliable.
Fixed orphaned credentials left behind on multi-user uninstall.
A successful re-authentication will cause the device profile to be re-evaluated.
Improved dashboard-managed client updates by running the updater only when needed.

Cloudflare One Client - Cloudflare One Client for macOS (version 2026.7.1210.1)

Fri, 31 Jul 2026 13:55:38 GMT

A new Beta release for the macOS Cloudflare One Client is now available on the beta releases downloads page.

This beta release includes the following changes and improvements:

Improved connection reliability: the client now swaps protocol order after repeated connectivity-check failures, which helps when HTTP/3 is blocked after the QUIC handshake.
Fixed issue where a certificate error could be incorrectly displayed right after the connection is established.
A DNS search domain parsing failure no longer prevents connection.
Fixed a MASQUE issue where the tunnel could stall while uploading at a high rate.
Fixed being unable to switch organizations when the client was stuck in the "Device not in organization" state.
Fixed the Home Screen dropdown popup not anchoring correctly.
Fixed a crash during dialog dismissal.
Increased tolerance for configurations with a large number of local domain fallback resolver IPs, so DNS resolution behaves correctly even when more fallback resolvers are configured than recommended.
Fixed the WARP client stealing window focus (for example, during reauth).
Fixed a client crash when connecting to a captive portal over Wi-Fi.
Fixed the system tray icon showing "disconnected" while the UI showed "connected".
A successful re-authentication will cause the device profile to be re-evaluated.
Improved dashboard-managed client updates by running the updater only when needed.

Access - Static OAuth client credentials for MCP server portals

Fri, 31 Jul 2026 00:00:00 GMT

MCP server portals can now connect to upstream MCP servers that require a pre-registered OAuth client. This supports OAuth providers that do not offer Dynamic Client Registration or have disabled it. This unlocks portal connections to major SaaS providers such as Slack and GitHub, whose MCP servers do not yet support DCR.

When adding an MCP server, administrators can enter the client ID and client secret from an OAuth application registered with the upstream provider. The configuration also supports custom OAuth endpoints, scopes, and the client_secret_post and client_secret_basic token endpoint authentication methods.

Cloudflare stores the client secret encrypted. Users still authenticate to the upstream server with their own accounts when they connect through a portal.

For setup instructions, refer to Configure manual OAuth credentials.

Browser Run - Browser Run adds a Playground to the Cloudflare dashboard

Fri, 31 Jul 2026 00:00:00 GMT

Browser Run now includes a Playground in the Cloudflare dashboard. Use it to try Quick Actions against a live browser without creating a Worker, installing an SDK, or deploying code first.

The Playground helps you test a target URL or raw HTML input, tune viewport and page-load settings, preview the output, and copy working code for the same request.

With the Playground, you can:

Capture visuals as screenshots or PDFs.
Generate multiple output formats in one request with the snapshot endpoint.
Extract HTML, Markdown, links, or scraped data.
Extract structured data with AI using a prompt and optional JSON Schema.

You can also configure desktop, laptop, tablet, mobile, or custom viewport sizes, set browser scale, choose page-load conditions, set timeouts, and wait for selectors before running a request.

Select Show Code to generate the same request as cURL, TypeScript SDK, Python, or Workers Binding code. For example, a screenshot request can be copied as a Workers Binding call:

interface Env {
	BROWSER: BrowserRun;
}

export default {
	async fetch(request, env): Promise<Response> {
		return await env.BROWSER.quickAction("screenshot", {
			url: "https://developers.cloudflare.com",
			viewport: {
				width: 1920,
				height: 1080,
			},
		});
	},
} satisfies ExportedHandler<Env>;

Requests made in the Playground incur Browser Run charges. AI extraction also incurs Workers AI charges.

To try the Playground, go to Browser Run in the Cloudflare dashboard and select Playground.

Go to Browser Run ↗

For more information, refer to the Quick Actions documentation.

Stream - Rotate Stream broadcast keys for live inputs

Fri, 31 Jul 2026 00:00:00 GMT

You can now rotate the broadcast credentials for a Stream live input without changing the live input identifier.

Use key rotation when live input credentials may have been shared with the wrong audience, exposed in client code or a screenshare, or need to be refreshed as part of your security process. Rotating keys revokes the old credentials, disconnects broadcasts using stale credentials, and returns refreshed credentials in the API response.

To rotate keys for a live input, make a POST request to the rotate_keys endpoint:

curl --request POST \
https://api.cloudflare.com/client/v4/accounts/{account_id}/stream/live_inputs/{live_input_identifier}/rotate_keys \
--header "Authorization: Bearer <API_TOKEN>"

Live input responses now also include keysRotatedAt, which indicates when the live input keys were last rotated. This field is omitted for live inputs whose keys have never been rotated.

For endpoint details, refer to Rotate keys for a live input. For usage guidance, refer to Manage live inputs.

Workers, Durable Objects - Inspect Worker startup performance with Wrangler

Fri, 31 Jul 2026 00:00:00 GMT

wrangler check startup now reports your Worker's raw and compressed bundle sizes. It also summarizes local CPU activity during startup directly in your terminal.

Large bundles and costly startup work can introduce cold-start latency, so use this command to find code and large dependencies that slow your Worker before it handles requests.

The summary includes sampled, active, garbage collection, and idle time. Wrangler continues to save a .cpuprofile file for detailed flamegraph analysis in Chrome DevTools or VS Code.

│ As such, CPU Profile can be used to understand where time is spent at startup, but the overall startup time in the profile should not be expected to exactly match what your Worker's startup time will be when deploying to Cloudflare.

The profile runs locally, so its duration will differ from startup time on Cloudflare. For authoritative startup time, deploy your Worker or upload a version.

Available in Wrangler version 4.116.0 or later. For more information, refer to wrangler check startup.

Access - Admins can turn on Code Mode by default for MCP portal users

Thu, 30 Jul 2026 00:00:00 GMT

MCP server portals now support four Code Mode policies: Off, Opt-in, On by default, and Enforced. Admins can choose whether Code Mode is unavailable, optional, enabled by default, or required for every session.

Existing portals retain their current behavior. Portals that previously allowed Code Mode use Opt-in, while portals that did not allow Code Mode use Off. New portals also use Opt-in by default.

Clients turn on Code Mode for an Opt-in portal with ?codemode=search_and_execute. The On by default policy lets clients opt out with ?codemode=off, which avoids nested code execution when a client runs its own Code Mode implementation. The Off and Enforced policies ignore client overrides.

The Cloudflare API exposes these policies through the code_mode field:

{
	"code_mode": "default_on"
}

The supported values are off, opt_in, default_on, and enforced. The previous allow_code_mode boolean is deprecated.

For configuration details and client behavior, refer to Code Mode policies.

AI Search - Use AI Search with the Agents SDK, AI SDK, and LangChain

Thu, 30 Jul 2026 00:00:00 GMT

You can now use AI Search directly from popular agent frameworks, adding grounded retrieval to an existing app instead of calling the REST API by hand. The new Agents section has guides for the Vercel AI SDK, LangChain, and the Cloudflare Agents SDK. The AI SDK integration is a new package, and the LangChain integration is a new retriever in the existing langchain-cloudflare package.

Vercel AI SDK

The ai-search-provider ↗ package connects AI Search to the AI SDK, and targets AI SDK v6 (ai@^6). Pass instance.chat() to generateText or streamText to generate a response grounded in your indexed content, with the retrieved chunks returned as sources. You can also expose instance.search() as a tool for agent loops.

import { createAISearchNamespace } from "ai-search-provider";
import { generateText } from "ai";

const aiSearch = createAISearchNamespace({ binding: env.AI_SEARCH });

const { text, sources } = await generateText({
	model: aiSearch.get("knowledge-base").chat(),
	messages: [{ role: "user", content: "How does caching work?" }],
});

import { createAISearchNamespace } from "ai-search-provider";
import { generateText } from "ai";

const aiSearch = createAISearchNamespace({ binding: env.AI_SEARCH });

const { text, sources } = await generateText({
	model: aiSearch.get("knowledge-base").chat(),
	messages: [{ role: "user", content: "How does caching work?" }],
});

LangChain

The langchain-cloudflare package (PyPI ↗, GitHub ↗) provides CloudflareAISearchRetriever, a standard LangChain retriever backed by AI Search. Use it on its own, wrap it with create_retriever_tool to give an agent a search tool, or drop it into a RAG chain. It works with REST credentials or a Worker binding inside a Python Worker.

from langchain_cloudflare import CloudflareAISearchRetriever

retriever = CloudflareAISearchRetriever(
    account_id=ACCOUNT_ID,
    api_token=API_TOKEN,
    instance_name="knowledge-base",
    retrieval_type="hybrid",
)

docs = retriever.invoke("How do I configure Workers AI?")

Cloudflare Agents SDK

The Cloudflare Agents SDK could already reach AI Search through the Workers binding. The new guide walks through building a stateful chat agent that provisions its own instance, indexes content, and searches it from a tool.

import { tool } from "ai";
import { z } from "zod";

const instance = env.AI_SEARCH.get("knowledge-base");

// Expose AI Search to the agent's model as a tool it can call.
const searchKnowledgeBase = tool({
	description: "Search the knowledge base for relevant content.",
	inputSchema: z.object({ query: z.string() }),
	execute: ({ query }) => instance.search({ query }),
});

import { tool } from "ai";
import { z } from "zod";

const instance = env.AI_SEARCH.get("knowledge-base");

// Expose AI Search to the agent's model as a tool it can call.
const searchKnowledgeBase = tool({
	description: "Search the knowledge base for relevant content.",
	inputSchema: z.object({ query: z.string() }),
	execute: ({ query }) => instance.search({ query }),
});

For the full walkthroughs, including creating an instance and indexing content, refer to the Agents guides.

Workers - Node.js 24 is now the default for Workers Builds

Thu, 30 Jul 2026 00:00:00 GMT

Workers Builds now uses Node.js 24.18.0 by default. The build image preinstalls Node.js 22.23.2 and 24.18.0.

You can continue to override the default with the NODE_VERSION environment variable, an .nvmrc file, or a .node-version file. For more information, refer to Override default versions.

WAF - WAF Release - 2026-07-29

Wed, 29 Jul 2026 00:00:00 GMT

This release introduces new rules and updates existing threat signatures to provide targeted protections for vulnerabilities in Nuxt Server Island components and Alibaba Fastjson deserialization routines, alongside enhanced protections for cloud metadata Server-Side Request Forgery (SSRF) and obfuscated command injection attempts.

Key Findings

Nuxt Server Island - RCE(GHSA-9473-5f9j-94wq): An unauthenticated vulnerability in Nuxt Server Islands where remote attackers can supply arbitrary component names or props to endpoints. Manipulating these parameters allows unauthenticated component Remote Code Execution (RCE) on the server.
Alibaba Fastjson JSONType Remote Code Execution: A unauthenticated remote code execution vulnerability in Alibaba Fastjson (≤ 1.2.83) during JSON deserialization. Under default configurations, attackers can execute arbitrary system commands, bypassing traditional classpath and gadget-based defenses.
Generic Protections (SSRF & Command Injection): Added improved detection logic targeting Server-Side Request Forgery (SSRF) in cloud-hosted applications, alongside new rules targeting obfuscated command injection patterns across request parameters.

1.1.1.1 - Improved DoH JSON formatting for additional record types

Tue, 28 Jul 2026 00:00:00 GMT

Cloudflare is rolling out updated formatting for the data field in the 1.1.1.1 DoH JSON API (application/dns-json). During the roll out responses may use either the old or new format.

Human-readable display for additional record types

Several record types previously returned their data field in RFC 3597 ↗ generic hex encoding (\# <length> <hex>). These now use standard presentation format:

CAA:        0 issue "letsencrypt.org"
NAPTR:      100 10 "s" "SIP+D2U" "" _sip._udp.example.com.
RP:         admin.example.com. txt.example.com.
IPSECKEY:   10 1 2 192.0.2.1 AwEA...
SVCB:       1 target.example.com. alpn=h2
HTTPS:      1 . alpn=h3,h2 ipv4hint=192.0.2.1
TLSA:       3 1 1 aabbccdd...
SSHFP:      1 2 aabbccdd...
OPENPGPKEY: AwEA...

Numeric DNSSEC algorithm identifiers

DNSSEC-related records now use numeric algorithm identifiers as defined in RFC 4034 ↗ instead of mnemonic names. This affects RRSIG, DS, CDS, DNSKEY, and CDNSKEY records. For example, RSASHA256 becomes 8, ECDSAP256SHA256 becomes 13, and ED25519 becomes 15. DS digest types also change from mnemonic to numeric: SHA-256 becomes 2.

Beforetxt

RRSIG:  A RSASHA256 2 300 ...
DS:     12345 RSASHA256 SHA-256 aabb...
DNSKEY: 257 3 RSASHA256 AwEA...

Aftertxt

RRSIG:  A 8 2 300 ...
DS:     12345 8 2 aabb...
DNSKEY: 257 3 8 AwEA...

Other formatting changes

HINFO character-strings are now individually quoted to remove ambiguity when values contain spaces:

Beforetxt

"data": "Intel Xeon Linux"

Aftertxt

"data": "\"Intel Xeon\" \"Linux\""

Agents, Workers - Cloudflare MCP servers support the new MCP 2026-07-28 Specification

Tue, 28 Jul 2026 00:00:00 GMT

Cloudflare's product-specific MCP servers now support the new MCP 2026-07-28 Specification. Each request runs on a fresh stateless server without an MCP protocol session or protocol-specific Durable Object.

The /mcp endpoint also accepts stateless requests from 2025 Streamable HTTP clients. Most clients can reconnect without configuration changes.

Use /mcp for new connections. Historical /sse URLs continue to work as aliases for the same Streamable HTTP handler, but they no longer serve the deprecated HTTP+SSE transport. If a client forces SSE transport, change it to Streamable HTTP or automatic transport detection.

Browser Run - Browser Run adds structured handoff for Human in the Loop

Tue, 28 Jul 2026 00:00:00 GMT

Browser Run now supports structured handoff for Human in the Loop workflows. Using Cloudflare-specific CDP commands, your agent can signal that it needs help, a human steps in through Live View to handle the task, and the agent resumes once the work is done.

For agents running multi-step browser workflows, a single login wall or unexpected prompt can fail the entire run. Previously, scripts had to manage human intervention manually by sharing a Live View URL and polling for completion. Structured handoff replaces this with a formal pause-and-resume flow.

The following example requests human intervention for a login page and waits for the human to finish before continuing:

const cdp = await page.createCDPSession();

// Get Live View URL for the human operator
const { devtoolsFrontendUrl } = await cdp.send("Cloudflare.getLiveView", {
	mode: "tab",
});
console.log(`Human input needed: ${devtoolsFrontendUrl}`);

// Request human intervention and wait for completion
const handoffComplete = new Promise((resolve) => {
	cdp.once("Cloudflare.handoffComplete", resolve);
});

await cdp.send("Cloudflare.handoff", {
	instructions: "Please log in with your credentials",
	timeout: 600000,
});

const result = await handoffComplete;
console.log(result.success ? "Handoff complete" : `Failed: ${result.reason}`);

Refer to the Human in the Loop documentation for the full API reference, examples, and best practices.

Cloudflare One, Gateway - Control Cloudflare Gateway DNS caching with a maximum TTL setting

Tue, 28 Jul 2026 00:00:00 GMT

You can now set a maximum time-to-live (TTL) for DNS responses returned by Gateway. When an upstream DNS record has a TTL that exceeds the configured maximum, Gateway caps it to your specified value. This ensures that DNS policy changes - such as blocking a newly identified malicious domain - take effect faster across all clients.

Traffic settings, showing a numeric input field that accepts values between 60 and 36,000 seconds" loading="lazy" decoding="async" width="2170" height="294">

The setting is available at two levels:

Account level - In Traffic Policies > Traffic Settings, under Proxy and inspection. This sets the default cap for all DNS locations.
Per-location - Each DNS location can inherit the account setting, disable the cap, or override it with a custom value.

Two new fields are also available in DNS logs: upstream_record_ttls (the original TTL from the upstream response) and applied_max_ttl (the cap Gateway applied). These appear in the DNS logs column picker and in Logpush datasets.

For more information, refer to Maximum DNS TTL.

Workers AI - Select models now require the Workers Paid plan

Tue, 28 Jul 2026 00:00:00 GMT

We are limiting Workers Free plan access to a few resource-intensive models so we can prioritize capacity for the broader Workers AI user base. This helps everyone get a more reliable inference experience, with fewer 429 and 3040 (Out of Capacity) errors.

The following models now require the Workers Paid plan:

On the Workers Free plan, requests to these models now return a 403 HTTP error (internal error 5035) prompting you to upgrade. The Workers Paid plan starts at $5 per month and still includes the 10,000 free Neurons per day allocation, with usage beyond that billed at each model's pricing.

Many models remain available on the Workers Free plan, including:

For the full list, refer to the Workers AI model catalog.

Workers - Workers tracing — write custom spans with new startActiveSpan() and span.end() runtime APIs

Tue, 28 Jul 2026 00:00:00 GMT

The Workers runtime now provides built-in tracing.startActiveSpan() and span.end() APIs, allowing you to write custom spans for operations that last beyond a single callback — for example, instrumenting a stream pipeline where the span should stay open until the stream is fully consumed.

This augments the existing API for writing custom spans, tracing.enterSpan(), which automatically ends a span when its callback is returned. With startActiveSpan(), the span remains open after the callback returns, and you call span.end() when the work is complete:

src/index.jsjs

import { tracing } from "cloudflare:workers";

const encoder = new TextEncoder();

export default {
	fetch() {
		return tracing.startActiveSpan("stream-response", (span) => {
			let timer;

			const body = new ReadableStream({
				start(controller) {
					controller.enqueue(encoder.encode("Starting...\n"));

					timer = setTimeout(() => {
						controller.enqueue(encoder.encode("Complete.\n"));
						controller.close();

						span.setAttribute("stream.status", "complete");
						span.end();
					}, 1000);
				},

				cancel() {
					if (timer !== undefined) clearTimeout(timer);

					span.setAttribute("stream.status", "cancelled");
					span.end();
				},
			});

			return new Response(body, {
				headers: { "content-type": "text/plain" },
			});
		});
	},
};

src/index.tsts

import { tracing } from "cloudflare:workers";

const encoder = new TextEncoder();

export default {
	fetch(): Response {
		return tracing.startActiveSpan("stream-response", (span) => {
			let timer: ReturnType<typeof setTimeout> | undefined;

			const body = new ReadableStream<Uint8Array>({
				start(controller) {
					controller.enqueue(encoder.encode("Starting...\n"));

					timer = setTimeout(() => {
						controller.enqueue(encoder.encode("Complete.\n"));
						controller.close();

						span.setAttribute("stream.status", "complete");
						span.end();
					}, 1000);
				},

				cancel() {
					if (timer !== undefined) clearTimeout(timer);

					span.setAttribute("stream.status", "cancelled");
					span.end();
				},
			});

			return new Response(body, {
				headers: { "content-type": "text/plain" },
			});
		});
	},
};

For more details, refer to the custom spans documentation.

Agents, Workers - Agents SDK adds MCP Specification 2026-07-28 support

Mon, 27 Jul 2026 00:00:00 GMT

Agents SDK v0.20.0 adds client and server support for the MCP 2026-07-28 release candidate ↗. Workers can serve tools, prompts, resources, and elicitation without an MCP transport session or Durable Object. Agents can connect to both MCP 2026-07-28 servers and existing legacy servers.

Client support

The MCP client manager now uses @modelcontextprotocol/client. For each connection, it probes for MCP 2026-07-28 support with server/discover. If the server does not support the stateless protocol, the client continues with the legacy initialize handshake on the same connection. Existing addMcpServer calls do not need a protocol-version setting or separate clients for each protocol generation.

For stateless requests, elicitation uses input_required through multi-round-trip requests (MRTR). The legacy path uses the same form and URL handlers for pushed requests. The SDK collects input, retries the original operation, and resolves the original callTool, getPrompt, or readResource promise with its final result.

OAuth callbacks now validate issuer metadata through the v2 SDK. Discovery state and issuer-bound credentials persist across browser redirects and Durable Object hibernation.

Run stateless servers

createMcpHandler now accepts a factory that returns a server from @modelcontextprotocol/server. The factory creates an isolated server for each request.

import { McpServer } from "@modelcontextprotocol/server";
import { createMcpHandler } from "agents/mcp/server";

function createServer() {
	return new McpServer({ name: "example", version: "1.0.0" });
}

export default {
	fetch(request, env, ctx) {
		return createMcpHandler(createServer)(request, env, ctx);
	},
};

import { McpServer } from "@modelcontextprotocol/server";
import { createMcpHandler } from "agents/mcp/server";

function createServer() {
	return new McpServer({ name: "example", version: "1.0.0" });
}

export default {
	fetch(request, env, ctx) {
		return createMcpHandler(createServer)(request, env, ctx);
	},
} satisfies ExportedHandler;

The isolated agents/mcp/server entry keeps McpAgent, WorkerTransport, MCP client transports, and SDK v1 modules out of stateless server bundles.

The Workers wrapper validates present browser Origins, supports explicit delegation to trusted Origin middleware, and exposes request handling plus typed change notifications.

Backward compatibility

The same createMcpHandler(createServer)(request, env, ctx) route serves MCP 2026-07-28 clients and legacy clients that use stateless requests. You do not need separate routes or tool definitions for ordinary tools, prompts, and resources.

McpAgent is deprecated and feature-frozen. Migrate existing McpAgent servers to the stateless handler at your earliest convenience. If a server depends on protocol sessions, RPC, pushed server-to-client requests, standalone streams, or replay, use the migration guide to design stateless equivalents and run both routes while clients transition.

Migrate existing SDK v1 servers

Upgrade the Agents SDK:

npm i agents@latest

yarn add agents@latest

pnpm add agents@latest

bun add agents@latest

Move ordinary SDK v1 server definitions into an SDK v2 factory and serve them with createMcpHandler. The handler's default legacy compatibility means most stateless deployments need only one route.

If an existing McpAgent server still needs sessionful features, add the stateless path beside it. Use isLegacyRequest() to send only legacy traffic to the existing route:

import { isLegacyRequest } from "@modelcontextprotocol/server";
import { createMcpHandler } from "agents/mcp/server";
import { MyMcpAgent } from "./legacy-server";
import { createServer } from "./server";

const stateless = createMcpHandler(createServer, {
	route: "/mcp",
	legacy: "reject",
});
const legacy = MyMcpAgent.serve("/mcp");

export default {
	async fetch(request, env, ctx) {
		if (await isLegacyRequest(request)) {
			return legacy.fetch(request, env, ctx);
		}
		return stateless(request, env, ctx);
	},
};

import { isLegacyRequest } from "@modelcontextprotocol/server";
import { createMcpHandler } from "agents/mcp/server";
import { MyMcpAgent } from "./legacy-server";
import { createServer } from "./server";

const stateless = createMcpHandler(createServer, {
	route: "/mcp",
	legacy: "reject",
});
const legacy = MyMcpAgent.serve("/mcp");

export default {
	async fetch(request: Request, env: Env, ctx: ExecutionContext) {
		if (await isLegacyRequest(request)) {
			return legacy.fetch(request, env, ctx);
		}
		return stateless(request, env, ctx);
	},
} satisfies ExportedHandler<Env>;

Migrate the remaining sessionful features, allow existing sessions to drain, then remove the legacy route. Refer to Migrate to MCP SDK v2 for package changes, compatibility limits, and rollout steps.

Deprecations in v0.20.0

This release deprecates the following Agents SDK APIs:

Deprecated API	Replacement	Status
`McpAgent`	Use an SDK v2 factory with `createMcpHandler` for stateless servers. Use the migration guide to replace stateful features before removing a legacy route.	Feature-frozen. No removal version is announced.
`createMcpHandler(v1Server, options)`	Move the server to an SDK v2 factory and call `createMcpHandler(factory, options)`. Use `createLegacyMcpHandler` only as a temporary bridge for sessionful features.	Scheduled for removal in the next major version.
`MCPClientManager.callTool(params, resultSchema, options)` and the equivalent `withX402Client` overload	Use `callTool(params, options)` or `callTool(confirm, params, options)`.	Compatibility overload. No removal version is announced.

The MCP 2026-07-28 draft separately deprecates Roots, Sampling, Logging, the old HTTP+SSE transport, and Dynamic Client Registration.

Audit Logs - Audit Logs v2 — Resource History

Mon, 27 Jul 2026 00:00:00 GMT

Audit Logs v2 now includes Resource History. For any audit log entry, you can see the sequence of previous changes to the same resource and view a side-by-side diff of what was modified.

Resource History uses the audit log entries you already have. There is no additional configuration, no backend recapture, and no changes to how audit logs are generated.

Dashboard:

Go to Manage Account > Audit Logs.
Open any audit log entry.
Select the History tab to see the full history for that resource.
Select any earlier entry to see a side-by-side diff of the fields that changed between it and the current entry.

API:

Use the History endpoint to retrieve the change history for any audit log entry:

GET https://api.cloudflare.com/client/v4/accounts/{account_id}/logs/audit/{id}/history

The endpoint is also available for organization-scoped audit logs at /organizations/{organization_id}/logs/audit/{id}/history.

For more information, refer to the Resource History documentation.

Workers - Run integration tests against your Worker's production build

Mon, 27 Jul 2026 00:00:00 GMT

Wrangler now provides createTestHarness(), an API for running integration tests against Workers built with Wrangler or the Cloudflare Vite plugin from any Node.js test runner.

The test harness starts a local Worker server with helpers for dispatching requests, resetting storage, and inspecting runtime logs.

This is useful for tests that need to:

Route requests across multiple Workers
Mock outbound fetch() requests with Node.js request mocking libraries such as MSW ↗
Run Playwright tests against a Worker

For example, this test starts two Workers and mocks an upstream API:

tests/vitest.test.jsjs

import { afterAll, afterEach, beforeAll, test } from "vitest";
import { http, HttpResponse } from "msw";
import { setupServer } from "msw/node";
import { createTestHarness } from "wrangler";

const network = setupServer();
const server = createTestHarness({
	workers: [
		/** Includes `"routes": ["example.com/*"]` */
		{ configPath: "./workers/web/wrangler.jsonc" },
		/** Includes `"routes": ["api.example.com/v1/*"]` */
		{ configPath: "./workers/api/wrangler.jsonc" },
	],
});

beforeAll(async () => {
	network.listen({ onUnhandledRequest: "error" });
	await server.listen();
});

afterEach(async () => {
	network.resetHandlers();
	await server.reset();
});

afterAll(async () => {
	network.close();
	await server.close();
});

test("routes requests to each Worker", async ({ expect }) => {
	// Mock the outbound fetch used to load user profiles.
	network.use(
		http.get("http://identity.example.com/profile/123", ({ params }) => {
			return HttpResponse.json({ id: 123, name: "Ada" });
		}),
	);

	const apiWorkerResponse = await server.fetch(
		"http://api.example.com/v1/users/123",
	);
	expect(await apiWorkerResponse.json()).toEqual({
		id: 123,
		name: "Ada",
	});

	const webWorkerResponse = await server.fetch("http://example.com/users/123");
	expect(await webWorkerResponse.text()).toBe("Profile: Ada");
});

tests/vitest.test.tsts

import { afterAll, afterEach, beforeAll, test } from "vitest";
import { http, HttpResponse } from "msw";
import { setupServer } from "msw/node";
import { createTestHarness } from "wrangler";

const network = setupServer();
const server = createTestHarness({
	workers: [
		/** Includes `"routes": ["example.com/*"]` */
		{ configPath: "./workers/web/wrangler.jsonc" },
		/** Includes `"routes": ["api.example.com/v1/*"]` */
		{ configPath: "./workers/api/wrangler.jsonc" },
	],
});

beforeAll(async () => {
	network.listen({ onUnhandledRequest: "error" });
	await server.listen();
});

afterEach(async () => {
	network.resetHandlers();
	await server.reset();
});

afterAll(async () => {
	network.close();
	await server.close();
});

test("routes requests to each Worker", async ({ expect }) => {
	// Mock the outbound fetch used to load user profiles.
	network.use(
		http.get("http://identity.example.com/profile/123", ({ params }) => {
			return HttpResponse.json({ id: 123, name: "Ada" });
		}),
	);

	const apiWorkerResponse = await server.fetch(
		"http://api.example.com/v1/users/123",
	);
	expect(await apiWorkerResponse.json()).toEqual({
		id: 123,
		name: "Ada",
	});

	const webWorkerResponse = await server.fetch("http://example.com/users/123");
	expect(await webWorkerResponse.text()).toBe("Profile: Ada");
});

Cloudflare now recommends createTestHarness() for integration tests instead of unstable_startWorker() or unstable_dev(). To start a development server programmatically, use the Vite createServer() ↗ API with the Cloudflare Vite plugin.

For more information about createTestHarness(), refer to the Integration test harness guide.

R2 - Sippy now supports Azure Blob Storage and S3-compatible storage providers

Fri, 24 Jul 2026 00:00:00 GMT

Sippy can now incrementally migrate data from Azure Blob Storage and any S3-compatible object storage provider to Cloudflare R2, in addition to Amazon S3 and Google Cloud Storage. Sippy copies objects to R2 as your application requests them, so you can start serving data from R2 without first moving your entire dataset or paying migration-specific egress fees.

Enable Sippy

Run the following command and follow the prompts to select and configure your source storage provider:

npx wrangler r2 bucket sippy enable <BUCKET_NAME>

For Azure Blob Storage, provide your storage account name, container name, and either an account key or a shared access signature (SAS) token with read and list permissions. For an S3-compatible provider, provide the S3 API endpoint URL and read-only Access Key ID and Secret Access Key.

After you enable Sippy, requests for objects that are not yet in R2 are served from your source bucket and copied to R2. Subsequent requests for those objects are served from R2.

For setup instructions and credential requirements, refer to the Sippy documentation.

Workers - Workers Builds now skips superseded queued builds

Fri, 24 Jul 2026 00:00:00 GMT

Workers Builds now automatically skips a queued build when a newer build for the same build trigger is also queued.

Agents - Agents SDK packages support AI SDK v6 and v7

Thu, 23 Jul 2026 00:00:00 GMT

The agents, @cloudflare/ai-chat, @cloudflare/codemode, and @cloudflare/think packages now support AI SDK v6 and v7. Existing applications can remain on v6 when updating these packages. Applications can also adopt v7 without changing the Cloudflare Agents APIs they use.

The supported peer ranges are ai@^6 || ^7 and @ai-sdk/react@^3 || ^4. Use matching major versions: pair AI SDK v6 with @ai-sdk/react v3, or pair AI SDK v7 with @ai-sdk/react v4.

To install the latest packages with AI SDK v7:

npm i agents@latest @cloudflare/ai-chat@latest @cloudflare/codemode@latest @cloudflare/think@latest ai@^7 @ai-sdk/react@^4

yarn add agents@latest @cloudflare/ai-chat@latest @cloudflare/codemode@latest @cloudflare/think@latest ai@^7 @ai-sdk/react@^4

pnpm add agents@latest @cloudflare/ai-chat@latest @cloudflare/codemode@latest @cloudflare/think@latest ai@^7 @ai-sdk/react@^4

bun add agents@latest @cloudflare/ai-chat@latest @cloudflare/codemode@latest @cloudflare/think@latest ai@^7 @ai-sdk/react@^4

Think normalizes streaming, tool completion events, and telemetry across both AI SDK versions. Existing v6 applications do not need to migrate these integrations before updating Think.

For setup and usage details, refer to the Think documentation.

Agents, Workers - Agents SDK reduces MCP schema conversion, adds exposure controls for MCP in Think and Code Mode SDK adds direct host APIs

Wed, 22 Jul 2026 00:00:00 GMT

This release reduces repeated MCP schema conversion and adds an opt-out for Think's automatic MCP tool exposure. It also lets non-AI-SDK hosts invoke the durable Code Mode runtime directly.

Control direct MCP tool exposure in Think

Agents SDK MCP clients now reuse converted input and output schemas while a live connection keeps the same tool catalog. This avoids converting every MCP JSON Schema to Zod again for each model turn.

@cloudflare/think also adds includeMcpTools. Set it to false when you expose MCP tools through Code Mode or another mechanism outside Think's automatic tool set:

import { Think } from "@cloudflare/think";

export class MyAgent extends Think {
	includeMcpTools = false;
	waitForMcpConnections = true;
}

import { Think } from "@cloudflare/think";

export class MyAgent extends Think<Env> {
	includeMcpTools = false;
	waitForMcpConnections = true;
}

This setting skips Think's automatic getAITools() call. MCP registration, restoration, discovery, raw catalog access, direct calls, and Code Mode connectors continue to work.

Use listTools() when you only need the raw MCP catalog. For connector setup, refer to Use MCP tools with Code Mode.

Invoke the Code Mode runtime without the AI SDK

@cloudflare/codemode@latest adds execute(), search(), and describe() to the durable runtime handle. MCP servers and other hosts can now execute code and discover connector methods without adapting the runtime to an AI SDK tool.

const matches = await runtime.search("create issue");
const docs = await runtime.describe(matches.results[0].path);
const outcome = await runtime.execute({
	code: `async () => github.create_issue({ title: "Bug" })`,
});

const matches = await runtime.search("create issue");
const docs = await runtime.describe(matches.results[0].path);
const outcome = await runtime.execute({
	code: `async () => github.create_issue({ title: "Bug" })`,
});

Search and describe results include requiresApproval: true for protected connector methods. Resolve a paused execution with the existing approve() and reject() methods.

For setup and exact method types, refer to Create a durable Code Mode runtime and the Code Mode API reference.

Upgrade

npm i agents@latest @cloudflare/think@latest @cloudflare/codemode@latest

yarn add agents@latest @cloudflare/think@latest @cloudflare/codemode@latest

pnpm add agents@latest @cloudflare/think@latest @cloudflare/codemode@latest

bun add agents@latest @cloudflare/think@latest @cloudflare/codemode@latest

Cloudflare One Client - Cloudflare One Client for Windows (version 2026.6.880.0)

Tue, 21 Jul 2026 16:55:55 GMT

A new GA release for the Windows Cloudflare One Client is now available on the stable releases downloads page.

This hotfix resolves a regression that caused a large increase in DNS-over-TCP queries to fallback and internal DNS servers. The client now sends fallback DNS queries over UDP first, falling back to TCP only when a response is truncated, instead of querying both protocols in parallel.

Cloudflare One Client - Cloudflare One Client for macOS (version 2026.6.880.0)

Tue, 21 Jul 2026 16:55:55 GMT

A new GA release for the macOS Cloudflare One Client is now available on the stable releases downloads page.

Cloudflare One Client - Cloudflare One Client for Linux (version 2026.6.880.0)

Tue, 21 Jul 2026 16:50:41 GMT

A new GA release for the Linux Cloudflare One Client is now available on the stable releases downloads page.

Cloudflare Fundamentals - Account Role API deprecated

Tue, 21 Jul 2026 00:00:00 GMT

The Account Roles API is deprecated and is being replaced by the Permission Groups API. An end of life date has not yet been established.

What you need to do

Review the Permission Groups API documentation; the response schema differs from the legacy Roles response.

Highlights

Integrations migrating to the Permission Groups API must obtain Permission Group IDs from that API and use them in the Account Members API policies request shape. Integrations that persist legacy Role IDs will need to remap their assignments.
The legacy Role response includes a top-level description and a permissions object keyed by resource type with edit/read flags.
The PermissionGroup response replaces those with a meta object containing label and scopes. Individual permissions are not returned as part of the permission group.
The new API supports the API Token authorization scheme. The legacy Email + API Key authorization schema is provided for backwards compatibility.

For more information, refer to API deprecations.

Sandbox SDK - Run Devin on Cloudflare using Devin Outposts

Tue, 21 Jul 2026 00:00:00 GMT

Devin Outposts ↗ lets you run Devin agents on Cloudflare. Each Devin session runs in its own isolated sandbox backed by Cloudflare Containers, so agents can execute code and use development tooling in an isolated environment.

Use Devin Outposts when you want Devin sessions to run on Cloudflare managed infrastructure, with each session isolated from the others.

To get started, refer to Run Devin on Cloudflare using Devin Outposts.

SSL/TLS - Faster and more secure TLS handshakes to your origins, automatically

Tue, 21 Jul 2026 00:00:00 GMT

Cloudflare now takes the guesswork out of TLS 1.3 key agreement with your origins. Automatic key exchange predicts the preferred algorithm and sends its key share in the first ClientHello, helping avoid a HelloRetryRequest and one extra network round trip.

Automatic key exchange is on for all existing zones and on by default for new zones. When an origin supports both classical and post-quantum key agreements, Cloudflare prefers the post-quantum X25519MLKEM768 hybrid key agreement.

To change this behavior, go to SSL/TLS > Overview > Origin connection & post-quantum encryption. Turn off Automatic key exchange to stop automatic scans and preference updates. Turning it off does not change your compliance requirements.

Compliance requirements apply only to TLS 1.3 connections. The Post-quantum hybrid option requires hybrid post-quantum key agreements support on your origin server. The Federal Information Processing Standards (FIPS) option requires FIPS-compliant key agreements. Select both to require key agreements that satisfy both, or leave both unselected to allow all supported key agreements.

For requirements, configuration options, and rollout details, refer to Automatic key exchange to origins.

WAF - WAF Release - 2026-07-21

Tue, 21 Jul 2026 00:00:00 GMT

This release introduces new rules for vulnerabilities in Adobe ColdFusion, Next.js, WordPress alongside updates to existing rules thereby providing enhanced generic protections against Server-Side Request Forgery (SSRF), Local File Inclusion (LFI), and Cross-Site Scripting (XSS).

WAF and framework adapter mitigations for Next.js vulnerabilities

Multiple security vulnerabilities ↗ were disclosed and patched by the Next.js team through July 2026 security release. These include denial of service, middleware and proxy bypass, server-side request forgery, information disclosure, and cache poisoning across a range of severities.

Several of the disclosed vulnerabilities are not possible to block at WAF layer,we strongly recommend updating your application and its dependencies immediately. Patched versions are available through v16.2.11 (Active LTS) and v15.5.21 (Maintenance LTS) to address these issues.

Advisory	CVE	Severity	Issue	WAF Coverage
Denial of Service in App Router using Server Actions	CVE-2026-64641	High	Crafted requests targeting Next.js applications using App Router with at least one Server Action can lead to excessive CPU usage. The CPU usage blocks processing of further requests in the same process, leading to Denial of Service.	WAF rule Next.js - DoS - CVE-2026-64641 () has been deployed to provide coverage.
Middleware / Proxy bypass in App Router applications using Turbopack and single locale	CVE-2026-64642	High	Next.js applications using App Router built with Turbopack and a single entry in config.i18n.locales are vulnerable to a middleware/proxy bypass. Accordingly, any authentication or security checks that a middleware/proxy may perform are bypassed.	This is a middleware bypass that unfortunately cannot be covered through Cloudflare WAF signature engine.
Server-Side Request Forgery in rewrites via attacker-controlled destination hostname	CVE-2026-64645	High	A rewrites() or redirects() rule that builds its external destination hostname from request-controlled input can be pointed at an arbitrary hostname, regardless of the rule's hostname suffix. For rewrites, this behavior enables Server-Side Request Forgery (SSRF); for redirects, Open Redirect can be achieved.	Existing SSRF rules provide adequate coverage for this vulnerability, no tailored WAF rule was developed.
Server-Side Request Forgery in Server Actions on custom servers	CVE-2026-64649	High	When a Server Action forwards or redirects a request, an attacker can cause the server to send that outbound request to a malicious host (Server-Side Request Forgery). This requires the attacker’s request to control Host-associated headers.	WAF rule Next.js - SSRF - CVE-2026-64649 () has been deployed to provide coverage.
Denial of Service in the Image Optimization API using SVGs	CVE-2026-64644	Medium	When self-hosting Next.js with the default image loader, the Image Optimization API can optimize remotely hosted images if configured (not enabled by default). If those images contain malicious content, the images can cause CPU exhaustion in the /_next/image endpoint.	Malicious request is unfortunately indistinguishable from a legitimate image optimization request, so no WAF rule has been created to address this vulnerability.
Unbounded Server Action payload in Edge runtime	CVE-2026-64646	Medium	A crafted request can lead to memory consumption on Server Actions in the Edge runtime. Next.js applications which use App Router and have at least one Server Action are affected.	Unfortunately there is no one size fits all rule that can be deployed through WAF in lieu of custom bodySizeLimit configurations, so no WAF rule has been created to address this vulnerability.
Unauthenticated disclosure of internal Server Function endpoints	CVE-2026-64643	Medium	In Next.js applications using App Router, Server Actions (use server) or use cache endpoint IDs can be globally disclosed. An attacker can use this for reconnaissance and as part of a broader attack chain.	WAF rule Next.js - Information Disclosure - CVE-2026-64643 () has been deployed to provide coverage.
Cache confusion of response bodies for requests with bodies	CVE-2026-64648	Medium	A server-side fetch with a request body may return a cached response body from a different request to the same URL but different body. This only applies for fetch calls of the shape fetch(new Request(init), aDifferentInit)	This is an application logic bug that unfortunately cannot be covered through Cloudflare WAF signature engine.
Cache confusion of response bodies for requests with bodies containing invalid UTF-8 byte sequences	CVE-2026-64647	Medium	A server-side fetch with a request body may return a cached response body from a different request to the same URL but different body. This only applies when receiving request bodies which contain invalid UTF-8 characters.	This is an application logic bug that unfortunately cannot be covered through Cloudflare WAF signature engine.

Key Findings

CVE-2026-48276: A path traversal vulnerability in Adobe ColdFusion file upload mechanisms allows unauthenticated attackers to write or upload files to arbitrary locations outside designated directories on the origin server.
CVE-2026-48282: A path traversal vulnerability in Adobe ColdFusion enables unauthenticated attackers to manipulate directory sequences and access restricted system files on the host filesystem.
CVE-2026-60137: An unauthenticated SQL injection vulnerability affecting WordPress. Threat actors exploit unsanitized input parameters to execute arbitrary SQL queries, leading to unauthorized database access, record manipulation, or data exfiltration.
CVE-2026-63030: A remote code execution vulnerability affecting WordPress core and plugin components. Remote, unauthenticated attackers can execute arbitrary system commands to gain unauthorized access or establish backdoors on host servers.

Access - Browser-based login for plaintext HTTP private applications

Mon, 20 Jul 2026 00:00:00 GMT

Cloudflare Access now uses the standard browser-based login flow for private applications served over plaintext HTTP on port 80.

Previously, plaintext HTTP private apps fell back to the same session flow used for SSH, RDP, and other non-HTTP protocols: users got an Authentication required pop-up from the Cloudflare One Client, then had to select the notification to open a browser and log in. Now, users hitting an HTTP private app see the Access login page directly in the browser and receive a standard Access application token on success.

This brings the HTTP experience in line with HTTPS apps (with Gateway TLS decryption turned on). No configuration change is required. The Cloudflare One Client is still required to route traffic to the private network, but it no longer manages the Access session for HTTP apps.

Other non-HTTP protocols (SSH, RDP, arbitrary TCP/UDP) continue to use the Cloudflare One Client notification flow.

Billing, Workers - Budget alerts now on by default for Pay-as-you-go accounts

Mon, 20 Jul 2026 00:00:00 GMT

We are turning on budget alerts by default for eligible Pay-as-you-go accounts. If your account does not already have a budget alert, Cloudflare will create one for you with a $10 account-level threshold. Your default alert will enable at the turn of your next billing cycle, so it will not fire based on usage you have already incurred.

We are rolling this out in cohorts over the coming weeks, so eligible accounts may see their default alert appear at different times.

The default alert behaves exactly like an alert you would create yourself. When your cumulative usage-based spend this cycle reaches the threshold, you receive an email notification. The alert is informational only. It does not cap your usage or impact your account in any way.

Usage is processed once per day for the prior day's activity, so budget alerts fire the day after the threshold is reached rather than in real time.

Budget alerts only consider spend on usage-based products. Recurring subscription fees, such as the Workers Paid plan fee or other monthly plan charges, are not included in the threshold calculation.

You can change the threshold, add additional alerts, or remove the default alert entirely from Manage Account > Billing > Billable Usage, or from your Notifications settings. If you already configured your own budget alert, nothing changes.

Enterprise contract accounts are not in scope.

For more information, refer to the Budget alerts documentation.

Durable Objects, Workers - View total SQLite storage for Durable Object namespaces

Mon, 20 Jul 2026 00:00:00 GMT

You can now monitor the total SQLite storage used by a Durable Object namespace over time in the Cloudflare dashboard. The new Total storage chart shows the maximum storage reported during each hour. This helps you identify storage growth, validate data cleanup, and investigate unexpected usage.

Go to Durable Objects ↗

The chart appears only for SQLite-backed Durable Object namespaces. It does not appear for namespaces that use the legacy key-value storage backend. Viewing storage for individual Durable Objects by ID or name is not supported.

For more information, refer to Metrics and analytics.

Cloudflare One Appliance, Cloudflare One, Cloudflare WAN - Restart, reboot, or shut down a Cloudflare One Appliance from the dashboard

Fri, 17 Jul 2026 00:00:00 GMT

You can now restart, reboot, or shut down a Cloudflare One Appliance directly from the dashboard or via API.

Restart — Restart managed services. Purges temporary and (optionally) persistent state.
Reboot — Power cycle the appliance. Optionally, purge persistent state. Re-applies configuration starting from scratch.
Shutdown — Power off the appliance. Optionally, purge persistent state. The machine will be offline until manually powered on again.

In the dashboard, go to Networking > Connectors > Appliances, select an appliance, then Edit > Operations to send an operation. Via API, POST to the /accounts/{account_id}/magic/connectors/{connector_id}/interrupts endpoint.

For details, refer to Appliance operations.

Email Service - Preview sent emails in the Activity log

Fri, 17 Jul 2026 00:00:00 GMT

You can now preview the content of sent emails directly from the Email Service Activity log. Expand a sent email and open the new Preview section to inspect the message as it was sent, across tabs for the rendered HTML body, the Text body, the Headers, the Attachments, and the full Raw RFC 5322 ↗ source.

Previously, the Activity log surfaced delivery and authentication metadata but not the message content, making rendering and content issues harder to debug. Message preview closes that gap.

To make messages previewable, turn on Email preview in your sending domain's settings. Previews cover messages sent while the setting is turned on and are retained for about seven days. Sending domains onboarded on or after 2026-07-02 have Email preview turned on automatically.

Refer to Email logs for more information.

Gateway - New header control options for Gateway HTTP policies

Fri, 17 Jul 2026 00:00:00 GMT

Cloudflare Gateway now supports advanced header control on Allow policies. Administrators can add, overwrite, or delete headers on matching requests using static values or dynamic variables.

Header operations

Gateway HTTP policies using the Allow action support three operations in rule_settings:

Operation	API field	Behavior
Add	`add_headers`	Appends a value to the header. Existing values are preserved.
Overwrite	`set_headers`	Replaces the header value. Creates the header if it does not exist.
Delete	`delete_headers`	Removes the header from the request.

Gateway applies operations in order: delete, then overwrite, then add.

Dynamic variables

Header values can include dynamic variables using the @{...} syntax. Gateway resolves variables at request time from identity, device, and network context.

Variable	Description
`@{identity.email}`	User email from the identity provider
`@{identity.name}`	User display name from the identity provider
`@{identity.id}`	Cloudflare identity UUID
`@{identity.groups}`	Identity provider group memberships
`@{identity.SAML}`	SAML attributes (if configured)
`@{identity.OIDC}`	OIDC claims (if configured)
`@{source.ip}`	Source IP of the connection
`@{destination.ip}`	Destination IP of the request
`@{device.id}`	Cloudflare One Client device UUID
`@{device.posture}`	Device posture check results (JSON string)

You can mix static text and dynamic variables in a single header value. For example, user-@{identity.email} resolves to user-jdoe@example.com.

For more information, refer to Custom headers.

Cloudflare Fundamentals, Organizations - Distributor, MSSP, and Agency partners can manage Organization members directly

Fri, 17 Jul 2026 00:00:00 GMT

Distributor, MSSP, and Agency partners on Cloudflare Organizations can now add and manage Organization Members directly from the Cloudflare dashboard, without help from Cloudflare.

Previously, adding a member to a Distributor, MSSP, or Agency Organization was a manual, Cloudflare-assisted process that required a request to Cloudflare and enrollment in a closed beta, and the dashboard Add member flow was blocked for these Organizations.

Now, Organization admins can add members themselves from Organization > Members > Add member, with no beta enrollment required.

New members receive access to the Organization's accounts through the same implicit-access model already used for enterprise Organizations. The Accounts list and the account switcher classify Distributor, MSSP, and Agency Organizations consistently with enterprise Organizations, so their accounts are labeled and grouped correctly in the dashboard.

Agency partners also gain access to the Organizations dashboard, while retaining access to their existing Tenant management dashboard.

Distributor, MSSP, and Agency Organizations are currently in beta.

For more information, refer to Manage Organization members.

WAF - WAF Release - 2026-07-17 - Emergency

Fri, 17 Jul 2026 00:00:00 GMT

This emergency release adds a new managed rule to block active exploitation of a critical remote code execution (RCE) and SQL injection (SQLi) vulnerability found in popular web frameworks.

Key Findings

Generic Frameworks - Unauthenticated RCE: Attackers can execute arbitrary system commands with web server privileges by sending malicious input containing invalid path sequences during request processing.
Generic Frameworks - SQLi: Attackers can execute unauthorized database queries due to a failure to sanitize input values within request parameters.

Access, Cloudflare One - Bulk print PDFs for browser-based RDP

Thu, 16 Jul 2026 00:00:00 GMT

Users in browser-based RDP sessions can now print multiple PDF files as a single print job. Copy the files to your clipboard on the remote machine, then select Print all PDFs in the clipboard panel. The files are combined into one PDF and sent to your local printer.

Bulk print is available in Chromium-based browsers and Firefox. For more information, refer to Print PDFs for browser-based RDP.

Flagship - Manage Flagship from the command line with Wrangler

Thu, 16 Jul 2026 00:00:00 GMT

Wrangler now includes wrangler flagship, a command suite for managing Flagship apps and feature flags from your terminal.

Create an app and, if you use it from a Worker, add it to your wrangler.json or wrangler.jsonc file as a binding:

wrangler flagship apps create "My Worker App" \
  --binding FLAGS \
  --update-config

Then create flags for the behavior you want to control. Flags can be booleans, strings, numbers, or JSON values:

wrangler flagship flags create <APP_ID> new-checkout

wrangler flagship flags create <APP_ID> checkout-flow \
  --variation control=old-checkout \
  --variation treatment=new-checkout \
  --default control \
  --type string

After a flag exists, change its default variation or use enable and disable commands as kill switches. Existing targeting rules continue to apply unless you change or clear them explicitly:

wrangler flagship flags update <APP_ID> checkout-flow --default treatment
wrangler flagship flags disable <APP_ID> checkout-flow
wrangler flagship flags enable <APP_ID> checkout-flow

For release workflows, use rollout, split, and rules to change exposure without redeploying your Worker:

wrangler flagship flags rollout <APP_ID> new-checkout \
  --to on \
  --percentage 25 \
  --by user_id

wrangler flagship flags split <APP_ID> checkout-flow \
  --weight control=80 \
  --weight treatment=20 \
  --by user_id

wrangler flagship flags rules update <APP_ID> checkout-flow \
  --priority 1 \
  --when "country equals US"

These commands can also be used from CI/CD pipelines, scripts, and AI agents to inspect Flagship state, update flag behavior, or roll back changes through Wrangler.

Refer to the wrangler flagship command reference for the full command guide.

Rules - Bot management fields and ASN support in Cache Rules

Thu, 16 Jul 2026 00:00:00 GMT

Bot management fields and ASN support in Cache Rules

Cache Rules now supports bot management fields and the ip.src.asnum field in expression filters. You can now build cache policies that differentiate between automated and human traffic, or segment caching behavior by autonomous system number (ASN).

This allows you to apply different caching strategies for verified bots, high-risk traffic, or specific network operators without affecting legitimate user requests. For example, you can set shorter cache TTLs for suspected bot traffic or bypass cache entirely for requests from specific ASNs.

New fields

The following fields are now available in Cache Rules expressions:

Field	Type	Description
`cf.bot_management.score`	Number	Bot score from `1` to `99`, where a lower value indicates a higher likelihood that the request originates from a bot.
`cf.bot_management.ja3_hash`	String	JA3 fingerprint of the request, which helps identify the client making the connection.
`cf.bot_management.ja4`	String	JA4 fingerprint of the request, which provides a more detailed client identification than JA3.
`cf.bot_management.verified_bot`	Boolean	Whether the request originates from a verified bot, such as a search engine crawler.
`cf.bot_management.static_resource`	Boolean	Whether the request is for a static resource and therefore exempt from bot detection.
`cf.bot_management.js_detection.passed`	Boolean	Whether the browser passed JavaScript detection when the feature is enabled.
`cf.bot_management.attack_score`	Number	Classifies the request by attack score, from `1` (likely automated) to `99` (likely human).
`cf.bot_management.api_score`	Number	Classifies the request by API score, from `1` (likely automated) to `99` (likely human).
`cf.bot_management.bot_tags["<TAG>"]`	Boolean	Whether the bot traffic matches the specified tag, such as `google` or `bing`.
`cf.bot_management.corporate_proxy`	Boolean	Whether the request originates from a known corporate proxy.
`ip.src.asnum`	Number	The autonomous system number (ASN) of the incoming request's IP address.

Example

Cache Rules expressions support combining these fields with other criteria. The following example sets a shorter cache TTL for API requests that originate from a high-risk bot or an unexpected ASN:

(http.request.uri.path contains "/api/" and cf.bot_management.score lt 30)
or
(http.request.uri.path contains "/api/" and not ip.src.asnum in {12345 67890})

To learn more, refer to the Cache Rules documentation and the Fields reference.

Gateway, DNS - Internal DNS is now generally available

Wed, 15 Jul 2026 00:00:00 GMT

Internal DNS is now generally available. Internal DNS provides authoritative and recursive DNS for private networks on the same global network and control plane you already use for public DNS, Zero Trust, and application services.

Why it matters

Consolidate DNS operations. Public and private DNS run on one platform, with one API, one audit trail, and one place to set policy.
Simplify split-horizon DNS. Internal and external resolution are defined as separate views over shared zones, managed from a single control plane — so there is no drift to chase down.
Extend Zero Trust to DNS. Resolver policies decide which users and devices resolve against which view, enforced by the same Gateway that already governs the rest of your traffic.

Setting up Internal DNS takes three steps: create a zone, create a view, and define a resolver policy.

POST /zones
{
  "account": {
    "id": "<ACCOUNT_ID>"
  },
  "name": "corp.internal",
  "type": "internal"
}

Internal DNS is included with Cloudflare Gateway for Enterprise customers. To get started, refer to the Internal DNS documentation.

Email Service, Queues - Subscribe to Email Sending events with Queues

Wed, 15 Jul 2026 00:00:00 GMT

You can now subscribe to Email Sending events through Queues event subscriptions and receive outbound transactional email lifecycle events on a queue. Each subscription is scoped to one sending domain — either the zone apex, such as example.com, or a verified sending subdomain, such as send.example.com.

Six event types are published: message.delivered, message.deferred, message.bounced, message.failed, message.rejected, and message.complained. Use them to track deliverability, react to bounces and complaints, and drive suppression or retry logic. Email Routing events are not published on this source.

Each event includes the message details, delivery status, and SMTP response:

{
	"type": "cf.email.sending.message.delivered",
	"source": {
		"type": "email.sending",
		"zoneId": "023e105f4ecef8ad9ca31a8372d0c353",
		"domain": "example.com"
	},
	"payload": {
		"messageId": "0101018f7d0c4d9a-msg-deadbeef",
		"recipient": "user@example.net",
		"terminal": true,
		"delivery": {
			"status": "delivered",
			"smtpStatusCode": "250"
		}
	}
}

Refer to Event subscriptions to see all event types and example payloads.

KV - Deprecate legacy Workers KV namespace API routes

Wed, 15 Jul 2026 00:00:00 GMT

The legacy Workers KV API routes under /accounts/{account_id}/workers/namespaces/* are deprecated as of July 15, 2026, and will stop working on October 15, 2026. Migrate to the documented Workers KV API routes under /accounts/{account_id}/storage/kv/namespaces/* before that date.

The legacy and replacement routes are interchangeable. They accept the same request parameters and return the same response payloads. To migrate, update the URL path from /workers/namespaces/ to /storage/kv/namespaces/.

What you need to do

Update any integration that calls a route under /accounts/{account_id}/workers/namespaces/ to use the equivalent route under /accounts/{account_id}/storage/kv/namespaces/. The migration is a direct URL path substitution — request parameters and response payloads are identical:

GET and POST /accounts/{account_id}/workers/namespaces → GET and POST /accounts/{account_id}/storage/kv/namespaces
GET, PUT, and DELETE /accounts/{account_id}/workers/namespaces/{namespace_id} → GET, PUT, and DELETE /accounts/{account_id}/storage/kv/namespaces/{namespace_id}
GET /accounts/{account_id}/workers/namespaces/{namespace_id}/keys → GET /accounts/{account_id}/storage/kv/namespaces/{namespace_id}/keys
GET /accounts/{account_id}/workers/namespaces/{namespace_id}/metadata/{key_name} → GET /accounts/{account_id}/storage/kv/namespaces/{namespace_id}/metadata/{key_name}
GET, PUT, and DELETE /accounts/{account_id}/workers/namespaces/{namespace_id}/values/{key_name} → GET, PUT, and DELETE /accounts/{account_id}/storage/kv/namespaces/{namespace_id}/values/{key_name}

For more information about the deprecation timeline, refer to API deprecations.

WAF - WAF Release - 2026-07-14

Tue, 14 Jul 2026 00:00:00 GMT

This release introduces new rules targeting critical infrastructure vulnerabilities. These include an unauthenticated memory disclosure flaw in Citrix NetScaler ADC and Gateway (CVE-2026-8451) and a high-severity pre-authentication remote code execution (RCE) vulnerability in Progress Kemp LoadMaster (CVE-2026-8037).

Key Findings

CVE-2026-8451: An insufficient input validation vulnerability affects Citrix NetScaler ADC and NetScaler Gateway appliances configured as a SAML Identity Provider (IdP). Remote, unauthenticated attackers can exploit this flaw by sending malformed requests to trigger a memory overread, allowing them to leak chunks of sensitive data from adjacent appliance memory.
CVE-2026-8037: A critical OS command injection vulnerability in Progress Kemp LoadMaster load balancers allows unauthenticated remote attackers to achieve remote code execution (RCE).

Cloudflare Web Analytics - Improved reliability for account-wide Web Analytics dashboards

Tue, 14 Jul 2026 00:00:00 GMT

Cloudflare Web Analytics (Real User Monitoring) has rolled out performance optimizations to significantly improve the stability and loading speed of account-wide dashboards.

For larger accounts (with >100 Web Analytics sites), loading the aggregate account-wide view would often fail, running into timeouts or unexpected interface errors due to the massive scale of parallel query processing. This update optimizes how high-volume multi-site data is queried to reduce errors and provide a snappier dashboard experience.

Accounts with up to 1,000 sites will now be able to load this account-wide aggregate view without experiencing misleading errors.

If you have an account with over 1,000 sites, we cannot currently aggregate over this volume due to processing constraints but you will now be presented with a clear error and instruction to filter to the relevant site(s) you wish to see the data for.

Workers - Platforms can now create Temporary Accounts via the Cloudflare API

Tue, 14 Jul 2026 00:00:00 GMT

Platforms can now create temporary preview accounts through the Cloudflare REST API. This lets your platform deploy a live Worker before the user signs in to Cloudflare.

With the Temporary Accounts API, coding agents, AI app builders, and other platforms can build a similar flow for generated Workers and supported resources.

Your platform can keep users in its onboarding flow while they generate, deploy, and test an application. Users do not need an existing Cloudflare account, and your platform does not need write access to one.

The API returns a claim URL that lets the user make the temporary account and its resources permanent.

Cloudflare Drop ↗ demonstrates this preview-and-claim pattern for static sites. Someone can upload a site, test and share it for one hour, then sign in or create an account only when they want to keep it.

This API expands the flow first introduced with wrangler deploy --temporary. Your backend now controls the provisioning and deployment experience directly:

Show Cloudflare's Terms of Service and Privacy Policy in your product, and require the user to accept them.
Request and solve a proof-of-work challenge.
Create a temporary preview account.
Deploy with the returned temporary account ID and API token.
Show the deployed Worker URL and claim URL to the user.

curl "https://api.cloudflare.com/client/v4/provisioning/previews/challenge" \
  -X POST \
  -H "Content-Type: application/json" \
  --data '{}'

curl "https://api.cloudflare.com/client/v4/provisioning/previews" \
  -X POST \
  -H "Content-Type: application/json" \
  --data '{
    "termsOfService": "https://www.cloudflare.com/terms/",
    "privacyPolicy": "https://www.cloudflare.com/privacypolicy/",
    "acceptTermsOfService": "yes",
    "challengeToken": "<CHALLENGE_TOKEN>",
    "solution": {
      "checkpoints": "<BASE64_CHECKPOINTS>"
    }
  }'

For the complete API flow, proof-of-work requirements, supported products, and limits, refer to Claim deployments (temporary accounts). For the background and design goals behind this flow, refer to Temporary Cloudflare Accounts for AI agents ↗.

Agents, Workers - Agents can respond to MCP elicitation requests

Mon, 13 Jul 2026 00:00:00 GMT

Agents connected to Model Context Protocol (MCP) servers with addMcpServer can now handle elicitation ↗ requests.

Elicitation lets an MCP server request user input while it handles a tool call. Form mode collects structured, non-sensitive data. URL mode asks for consent before opening an out-of-band flow, such as third-party authorization or payment.

sequenceDiagram
    participant User
    participant Agent as Agent (MCP client)
    participant Server as MCP server
    participant Browser

    Server->>Agent: elicitation/create
    Agent->>User: Show server, reason, and input or URL
    User->>Agent: Submit, open, decline, or cancel
    Agent->>Browser: Open URL after consent (URL mode)
    Agent->>Server: accept, decline, or cancel
    Server-->>Agent: Optional URL completion notification

import { Agent } from "agents";

export class MyAgent extends Agent {
	onStart() {
		this.mcp.configureElicitationHandlers({
			form: (request, serverId) => this.forwardToUser(request, serverId),
			url: (request, serverId) => this.forwardToUser(request, serverId),
		});
	}

	forwardToUser(request, serverId) {
		// Show the request in your UI and resolve after the user responds.
		throw new Error(
			`Implement elicitation for ${serverId}: ${request.params.message}`,
		);
	}
}

import { Agent } from "agents";
import type { ElicitRequest, ElicitResult } from "agents/mcp";

export class MyAgent extends Agent<Env> {
	onStart() {
		this.mcp.configureElicitationHandlers({
			form: (request, serverId) => this.forwardToUser(request, serverId),
			url: (request, serverId) => this.forwardToUser(request, serverId),
		});
	}

	private forwardToUser(
		request: ElicitRequest,
		serverId: string,
	): Promise<ElicitResult> {
		// Show the request in your UI and resolve after the user responds.
		throw new Error(
			`Implement elicitation for ${serverId}: ${request.params.message}`,
		);
	}
}

Connections advertise only the modes with configured handlers. An Agent without handlers advertises no elicitation capability, which lets the server use its fallback. The SDK stores the advertised modes with each MCP server registration so they survive Durable Object hibernation. Callback functions remain in memory and reattach when onStart() runs.

For implementation details and a browser forwarding pattern, refer to MCP client elicitation. The mcp-client ↗ and mcp-elicitation ↗ examples implement both sides.

Challenges - Precursor introduces session-based bot detection

Mon, 13 Jul 2026 00:00:00 GMT

Precursor is rolling out to all customers starting today. Precursor is client-side JavaScript that enables session-based bot detection.

You can read the announcement blog ↗ for background on why we built Precursor and how session-level behavioral detection works.

With Precursor enabled, Cloudflare can:

Continuously evaluate behavioral signals across a session
Re-validate challenge clearance as behavior changes
Update bot scores with session context
Provide client-side visibility where none previously existed

It integrates with existing protections, including Security Rules, and can be enabled directly from the Cloudflare dashboard with configurable modes to balance security and user experience.

To learn more, refer to the Precursor documentation.

Cloudflare Fundamentals - Origin Content Signals for Markdown for Agents

Mon, 13 Jul 2026 00:00:00 GMT

Markdown for Agents now preserves security- and cache-relevant response headers from your origin when converting HTML to Markdown:

Markdown for Agents preserves security headers such as Strict-Transport-Security (HSTS), Content-Security-Policy (CSP), X-Frame-Options, Set-Cookie, and CORS headers (for example, Access-Control-Allow-Origin) on the converted response.
Caching headers (Cache-Control, Expires, Age) continue to pass through.

Your origin's Content Signals ↗ policy is now authoritative. If your origin sets a content-signal header, Markdown for Agents preserves it. When the origin does not send one, Cloudflare adds the default Content-Signal: ai-train=yes, search=yes, ai-input=yes.

This release also fixes relative link resolution for directory-style base URLs (those ending in a trailing slash). Previously, relative links such as ../page/ could resolve one path segment too high and return a 404. Links are now resolved correctly per RFC 3986 ↗.

Refer to our developer documentation for more details.

R2, R2 Data Catalog - R2 Data Catalog now supports read-only API tokens

Mon, 13 Jul 2026 00:00:00 GMT

R2 Data Catalog now accepts read-only API tokens, so query engines and clients that only read data no longer need a read-write token. Previously, every catalog operation required an Admin Read & Write token, which granted read-only clients more access than they needed.

You can now authenticate your Iceberg engine based on your workload:

Read-only operations (such as listing namespaces, loading tables, and querying data) work with an Admin Read only token (R2 Data Catalog read and R2 storage read).
Write operations (such as creating or dropping tables and committing transactions) continue to require an Admin Read & Write token.

This lets you follow the principle of least privilege — for example, using a read-write token for the pipeline that writes to your tables and read-only tokens for engines like R2 SQL, DuckDB, or PyIceberg that query them.

Note that credentials vended by the catalog inherit the R2 storage permissions of the token used to authenticate. To ensure read-only access to your underlying data, scope the R2 storage permission to read-only as well.

For details on choosing and creating the right token, refer to Authenticate your Iceberg engine.

R2 Data Catalog - R2 Data Catalog compaction now optimizes manifest files

Mon, 13 Jul 2026 00:00:00 GMT

R2 Data Catalog, a managed Apache Iceberg ↗ catalog built into R2, now automatically optimizes manifest files as part of compaction.

Manifest files track the data files that make up an Iceberg table. As a table accumulates many small or fragmented manifests, query engines must read more metadata during query planning, which slows down queries even before any data is scanned.

When compaction runs, R2 Data Catalog now rewrites and clusters manifest files by partition as a best-effort pre-step. This consolidates fragmented manifests, reduces the number of manifests a query engine must open, and lowers metadata I/O overhead. Tables that are already well-clustered are skipped, so the operation only runs when it provides a benefit.

This happens automatically for tables with compaction enabled — no configuration changes are required.

For more information, refer to Table maintenance.

Data Loss Prevention - Source code detection improvements

Fri, 10 Jul 2026 00:00:00 GMT

Data Loss Prevention (DLP) source code detection now focuses on identifying whole source code file uploads and downloads. Previously, source code detection performed partial scans resulting in a higher rate of false positives. Since only whole source code files are evaluated, code embedded in other content — such as chat messages, documentation, or code samples — is no longer flagged as source code, removing a common source of false positives.

Source code detection requires a minimum of 500 characters to evaluate a file. Files below this threshold are not flagged to reduce noise. This threshold filters out small fragments that lack enough context for reliable classification.

Enable and set confidence levels to tune match sensitivity. A higher confidence level reduces false positives by requiring stronger signals that the content is truly source code. A lower confidence level catches more files at the cost of additional noise.

Source code detection applies to standalone source code files in Gateway HTTP policies. It does not detect source code embedded within other file types or payloads, such as .docx files or chat messages.

For more information, refer to Source Code predefined profiles.

Workers AI - Plain text output for Markdown Conversion

Fri, 10 Jul 2026 00:00:00 GMT

The Markdown Conversion service now supports a new output conversion option that controls the format of the converted content.

Set output.format to text to receive plain text with Markdown syntax removed. The default value is markdown, so existing conversions are unchanged.

Use the env.AI binding:

await env.AI.toMarkdown(
	{ name: "page.html", blob: new Blob([html]) },
	{
		conversionOptions: {
			output: { format: "text" },
		},
	},
);

await env.AI.toMarkdown(
	{ name: "page.html", blob: new Blob([html]) },
	{
		conversionOptions: {
			output: { format: "text" },
		},
	},
);

Or call the REST API:

curl https://api.cloudflare.com/client/v4/accounts/{ACCOUNT_ID}/ai/tomarkdown \
  -H 'Authorization: Bearer {API_TOKEN}' \
  -F 'files=@index.html' \
  -F 'conversionOptions={"output": {"format": "text"}}'

When you request text output, the format field of each result is set to text. For more details, refer to Conversion Options.

Workflows - Workflows now supports delay functions when retrying

Thu, 09 Jul 2026 12:00:00 GMT

With Workflows, you can configure built-in retry behavior for each step. Previously, you could configure step retries with fixed delay durations, such as seconds, minutes, or hours, and backoff strategies such as constant, linear, or exponential.

Step retries now support dynamic delay functions. Instead of choosing only a base delay and backoff strategy, pass a function to retries.delay and calculate the next delay from the failed attempt and thrown error.

This is useful when retries should depend on the failure. Your Workflow may need to wait longer after a rate-limit error, but retry sooner after a short network failure. The delay function can also accommodate provider guidance if, for example, a downstream API returns a Retry-After value in its error messaging.

await step.do(
	"sync customer",
	{
		retries: {
			limit: 5,
			delay: ({ ctx, error }) => {
				if (error.message.includes("rate limit")) {
					return `${ctx.attempt * 30} seconds`;
				}

				return "10 seconds";
			},
		},
	},
	async () => {
		await syncCustomer();
	},
);

await step.do(
	"sync customer",
	{
		retries: {
			limit: 5,
			delay: ({ ctx, error }) => {
				if (error.message.includes("rate limit")) {
					return `${ctx.attempt * 30} seconds`;
				}

				return "10 seconds";
			},
		},
	},
	async () => {
		await syncCustomer();
	},
);

Dynamic delay functions can return a duration string, a number, or a promise that resolves to a duration. Use them to add adaptive retry behavior without writing separate queue or scheduling logic. For more information, refer to Sleeping and retrying.

Digital Experience Monitoring - Wi-Fi signal and network performance analytics for Cloudflare One Client devices

Thu, 09 Jul 2026 00:00:00 GMT

Digital Experience Monitoring (DEX) provides visibility into device, network, and application performance across your Cloudflare SASE deployment.

The Device Monitoring page now analyzes hardware and network data between a Cloudflare One Client device and Cloudflare's edge, so you can diagnose connectivity and performance issues. Previously, this data was only available in raw DEX Device State Event logs, which required you to build your own analytics to interpret it.

A summary at the top of the page shows the health of each category at a glance, using Good, Fair, and Poor labels:

Connection — connection status, Cloudflare One Client mode, and tunnel type over time
Wi-Fi signal strength — signal measured in dBm over time, with thresholds that flag a weak signal
Traffic performance — upstream and downstream performance, including network throughput on the active interface
Device health — hardware metrics such as CPU, memory, and disk

You can filter by category and adjust the time range to correlate a device's metrics with a user's reported issue.

These analytics are available to all Cloudflare One customers at no additional cost.

To learn more, refer to the DEX monitoring documentation.

DNS - New DNS Firewall UX with more dashboard settings

Thu, 09 Jul 2026 00:00:00 GMT

The DNS Firewall page in the Cloudflare dashboard has been refreshed, bringing several settings that were previously API-only into the UI and modernizing how you view and manage your DNS Firewall clusters.

What is new

More settings in the dashboard: cluster options that were previously only configurable through the API — such as attack mitigation, rate limiting, negative TTL, and resolver subnet — are now available directly in the dashboard.
Better table experience: the DNS Firewall cluster table has been revised to surface cluster details at a glance, with resizable columns and the option to show or hide columns to tailor the view to your workflow.
New create and edit UX: adding and editing clusters now uses a modernized form that groups related settings together, making configuration faster and clearer.

Availability

Available to all DNS Firewall customers as part of their existing subscription.

Where to find it

In the Cloudflare dashboard, go to the DNS Firewall page.

Go to Clusters ↗

For more information, refer to DNS Firewall.

Durable Objects, Workers - New Durable Object namespaces must use the SQLite storage backend

Thu, 09 Jul 2026 00:00:00 GMT

If your account does not already have a key-value (KV) backed Durable Object namespace, you can no longer create new ones. New Durable Object namespaces must use the SQLite storage backend, which has been recommended for all new Durable Objects since it became generally available ↗ in 2024.

Create a new class with a new_sqlite_classes migration:

{
  "$schema": "./node_modules/wrangler/config-schema.json",
  "migrations": [
    {
      "tag": "v1",
      "new_sqlite_classes": [
        "MyDurableObject"
      ]
    }
  ]
}

[[migrations]]
tag = "v1"
new_sqlite_classes = ["MyDurableObject"]

SQLite-backed Durable Objects have feature parity with the key-value backend — including the key-value storage API — and additionally support relational SQL queries and point-in-time recovery to restore an object's storage to any point in the past 30 days.

If you attempt to create a new key-value backed namespace (a new_classes migration) on an affected account, the deployment fails with the following error:

Creating new key-value backed Durable Object namespaces is no longer supported on this account. Please create a namespace using a `new_sqlite_classes` migration instead.

This change only affects accounts that are not already using the key-value storage backend. Accounts with at least one existing key-value backed namespace can still create new ones for now, and the Workers Free plan has only ever supported SQLite-backed Durable Objects. It is part of a broader move toward SQLite as the single storage backend for Durable Objects, ahead of a future migration path for existing key-value backed objects.

For more information, refer to Durable Objects migrations.

Cloudflare Tunnel, Cloudflare Tunnel for SASE, Cloudflare Mesh - Zero Trust Networks route endpoints and Cloudflare Tunnel connections field retiring on October 5, 2026

Thu, 09 Jul 2026 00:00:00 GMT

On October 5, 2026, two changes take effect across the Zero Trust Networks API and Cloudflare Tunnel API: the CIDR-encoded route endpoints are removed, and tunnel list and get responses no longer include the connections field. If you manage private network routes or read tunnel connection details through the API, cloudflared, Terraform, or another integration, review the changes in the following sections and migrate before the removal date.

Route endpoints

The CIDR-encoded route endpoints are deprecated in favor of the standard, route_id-based endpoints that already exist today. Both sets of endpoints route a private network through Cloudflare Tunnel or Cloudflare Mesh (the API still refers to Mesh nodes as warp_connector) — only the request shape changes.

Deprecated endpoints (removed October 5, 2026):

Create a tunnel route (CIDR Endpoint): POST /accounts/{account_id}/teamnet/routes/network/{ip_network_encoded}
Update a tunnel route (CIDR Endpoint): PATCH /accounts/{account_id}/teamnet/routes/network/{ip_network_encoded}
Delete a tunnel route (CIDR Endpoint): DELETE /accounts/{account_id}/teamnet/routes/network/{ip_network_encoded}

Replacement endpoints:

Create a tunnel route: POST /accounts/{account_id}/teamnet/routes
Update a tunnel route: PATCH /accounts/{account_id}/teamnet/routes/{route_id}
Delete a tunnel route: DELETE /accounts/{account_id}/teamnet/routes/{route_id}

What is changing

	Deprecated (CIDR-encoded path)	Replacement
Route identifier	URL-encoded CIDR in the path (`/network/{ip_network_encoded}`)	`route_id` in the path (`network` moves to the request body on create)
Create	`POST .../teamnet/routes/network/{ip_network_encoded}`	`POST .../teamnet/routes` with `network` and `tunnel_id` in the body
Update	`PATCH .../teamnet/routes/network/{ip_network_encoded}`	`PATCH .../teamnet/routes/{route_id}`
Delete	`DELETE .../teamnet/routes/network/{ip_network_encoded}`	`DELETE .../teamnet/routes/{route_id}`

Action required

Capture each route's route_id by calling List tunnel routes, or read it from the response the first time you create a route with the replacement endpoint.
Update any scripts, backend services, or CI/CD pipelines that call the CIDR-encoded endpoints directly.
If you manage routes with the cloudflared tunnel route ip add | delete commands, upgrade cloudflared to the latest version ↗.
If you manage routes with Terraform, make sure you are on a current version of the cloudflare_zero_trust_tunnel_cloudflared_route ↗ resource and the Cloudflare Terraform provider ↗.

# Before: create a route by URL-encoding the CIDR into the path
curl https://api.cloudflare.com/client/v4/accounts/$ACCOUNT_ID/teamnet/routes/network/172.16.0.0%2F16 \
     -H 'Content-Type: application/json' \
     -H "Authorization: Bearer $CLOUDFLARE_API_TOKEN" \
     -d '{"tunnel_id": "'$TUNNEL_ID'", "comment": "Example comment for this route."}'

# After: create a route with the network in the request body
curl https://api.cloudflare.com/client/v4/accounts/$ACCOUNT_ID/teamnet/routes \
     -H 'Content-Type: application/json' \
     -H "Authorization: Bearer $CLOUDFLARE_API_TOKEN" \
     -d '{"network": "172.16.0.0/16", "tunnel_id": "'$TUNNEL_ID'", "comment": "Example comment for this route."}'

# After: update or delete a route using its route_id
curl -X PATCH https://api.cloudflare.com/client/v4/accounts/$ACCOUNT_ID/teamnet/routes/$ROUTE_ID \
     -H 'Content-Type: application/json' \
     -H "Authorization: Bearer $CLOUDFLARE_API_TOKEN" \
     -d '{"comment": "Updated comment for this route."}'

curl -X DELETE https://api.cloudflare.com/client/v4/accounts/$ACCOUNT_ID/teamnet/routes/$ROUTE_ID \
     -H "Authorization: Bearer $CLOUDFLARE_API_TOKEN"

Cloudflare Tunnel and Cloudflare Mesh connections

Starting the same day, the connections array is removed from list and get responses for Cloudflare Tunnel and Cloudflare Mesh nodes (the cfd_tunnel and warp_connector API resources). Query the dedicated connections endpoint instead of reading the field off the tunnel or node object.

This affects:

GET /accounts/{account_id}/cfd_tunnel — connections removed from each item in result
GET /accounts/{account_id}/cfd_tunnel/{tunnel_id} — connections removed from result
GET /accounts/{account_id}/warp_connector — connections removed from each item in result
GET /accounts/{account_id}/warp_connector/{tunnel_id} — connections removed from result

Action required

Fetch connection details from the tunnel-specific connections endpoint instead of parsing it off the list or get response. For Cloudflare Tunnel, call GET /accounts/{account_id}/cfd_tunnel/{tunnel_id}/connections. For Cloudflare Mesh, call GET /accounts/{account_id}/warp_connector/{tunnel_id}/connections.

# Before: read connections off the tunnel object
curl https://api.cloudflare.com/client/v4/accounts/$ACCOUNT_ID/cfd_tunnel/$TUNNEL_ID \
     -H "Authorization: Bearer $CLOUDFLARE_API_TOKEN"

# After: query connections directly
curl https://api.cloudflare.com/client/v4/accounts/$ACCOUNT_ID/cfd_tunnel/$TUNNEL_ID/connections \
     -H "Authorization: Bearer $CLOUDFLARE_API_TOKEN"

Update any dashboards, monitoring scripts, or automation that parses connections from the tunnel list or get response. cloudflared and the Cloudflare Terraform provider do not read this field, so no changes are required on their side for this part of the update.

Why we are making these changes

Smaller, faster responses. Cloudflare Tunnel and Cloudflare Mesh nodes with many connections no longer inflate every list and get call — connection detail is only fetched when you need it.
A single way to identify a route. Consolidating on route_id removes the need to URL-encode CIDR ranges into the path and matches how every other resource in the Zero Trust Networks API is addressed.
Consistency across the API. Both changes align these endpoints with Cloudflare's standard REST conventions for resource identifiers and nested detail endpoints.

To learn more, refer to the Zero Trust Networks API, the Cloudflare Tunnel API, and Routes documentation.

Workers - Send npm package dependency metadata with Worker uploads

Thu, 09 Jul 2026 00:00:00 GMT

Wrangler now collects npm package dependency information from your project's package.json during wrangler deploy and wrangler versions upload, and includes it in the upload metadata sent to the Cloudflare API. This data, each dependency's name, declared version range, and exact installed version, enables dependency analytics and future supply chain security features such as vulnerability alerting.

To opt out, set dependencies_instrumentation.enabled to false in your Wrangler configuration file:

{
	"dependencies_instrumentation": {
		"enabled": false
	}
}

[dependencies_instrumentation]
enabled = false

For more details, refer to Wrangler configuration.

AI Search - Filter AI Search list items by exact object key

Wed, 08 Jul 2026 00:00:00 GMT

In AI Search, you can upload files to an instance, or connect a data source such as an R2 bucket, to make your content searchable with natural language. Each file becomes an item identified by an object key (its filename or path). The list items endpoint returns the items in an instance.

That endpoint now accepts a key query parameter, so you can look up a single item by its exact object key without paging through the full list. This complements the existing item_id filter for when you know the key but not the ID.

curl "https://api.cloudflare.com/client/v4/accounts/<ACCOUNT_ID>/ai-search/instances/<INSTANCE_NAME>/items?key=docs/readme.md" \
  -H "Authorization: Bearer <API_TOKEN>"

Keys are unique per data source, so combine key with source (for example, source=builtin) to disambiguate when the same key exists across multiple sources.

For more information, refer to managing items.

Workers AI, AI Search - Workers AI toMarkdown and AI Search now supports GIF and BMP image conversion

Wed, 08 Jul 2026 00:00:00 GMT

Workers AI Markdown conversion (toMarkdown) now supports .gif and .bmp image files, in addition to the JPEG, PNG, WebP, and SVG formats already supported.

GIF and BMP files run through the same image pipeline as other formats. Each image is resized if needed (and for animated GIFs, only the first frame is used), then passed to an object-detection model to identify what it contains. Those detected objects prompt a vision model that writes a natural-language description of the image, which becomes searchable, machine-readable Markdown.

AI Search uses toMarkdown automatically to process the files it ingests, so any .gif and .bmp files are included the next time your index syncs, with no configuration changes required. This helps when your content mixes formats, for example a support knowledge base full of screenshots or an archive of BMP scans.

Learn more about Markdown conversion and the full list of AI Search's supported file types.

Cloudflare One, Cloudflare WAN - IPsec downgrade protection (beta)

Wed, 08 Jul 2026 00:00:00 GMT

Cloudflare IPsec now supports the IKE_SA_INIT_FULL_TRANSCRIPT_AUTH ↗ IKEv2 extension to protect against downgrade attacks on IPsec tunnels.

IKEv2's original authentication design has each endpoint sign only its own outbound messages, not the full handshake transcript. A quantum-capable on-path attacker ↗ can exploit this to bypass post-quantum key exchange by downgrading the connection to classical cryptography. The IKE_SA_INIT_FULL_TRANSCRIPT_AUTH extension addresses this by having both peers sign the entire handshake transcript during the authentication exchange, preventing an attacker from manipulating the negotiation without detection.

Key details:

Available in beta for Cloudflare WAN and Magic Transit IPsec tunnels.
Cloudflare sends the IKE_SA_INIT_FULL_TRANSCRIPT_AUTH notification unconditionally as a responder when the feature flag is enabled.
Both the initiator (your device) and responder (Cloudflare) must support the extension for downgrade protection to be effective.
This feature is currently gated by a per-account feature flag. Contact your account team to turn it on.

Refer to Downgrade protection for more details.

Cloudflare Network Firewall, Magic Transit, Cloudflare WAN - IP lists, IDS, and SIP rules supported in Unified Routing

Wed, 08 Jul 2026 00:00:00 GMT

Cloudflare Advanced Network Firewall IP lists, IDS, and SIP rules are now supported for accounts using Unified Routing mode. These features require a Cloudflare Advanced Network Firewall subscription.

Support for additional features - Threat Intel Lists, Rate Limiting, and Managed Rulesets - is planned.

For the full list of current beta limitations, refer to Traffic steering beta limitations.

R2 SQL - Query R2 Data Catalog tables with R2 SQL from the dashboard

Wed, 08 Jul 2026 00:00:00 GMT

You can now query your R2 Data Catalog tables with R2 SQL directly from the Cloudflare dashboard, without installing a CLI or wiring up a client. This makes it easy to explore your Apache Iceberg ↗ data, validate queries, and inspect results in one place.

To get started, go to R2 Data Catalog ↗ in the Cloudflare dashboard and select Query data to launch the built-in SQL editor. From there you can:

Write and run queries interactively — Iterate on R2 SQL directly in the browser with syntax highlighting and autocomplete, instead of re-running commands through Wrangler or the REST API.
Explore your data — Explore your namespaces and tables alongside the editor so you can discover what's queryable without leaving the page or using other tools.
Understand results and performance — View result sets with per-query statistics, export them, and get helpful EXPLAIN outputs to see exactly how a query runs.

Workers AI - Moondream 3.1 now available on Workers AI

Wed, 08 Jul 2026 00:00:00 GMT

Partnering with Moondream ↗ to bring their latest model @cf/moondream/moondream3.1-9B-A2B to Workers AI. Moondream 3.1 is a fast vision language model built on a mixture-of-experts architecture with 9B total parameters and 2B active, delivering frontier-level visual reasoning while retaining fast, cost-efficient inference.

Moondream 3.1 is designed for real-world vision tasks, with a 32K token context window for handling complex queries and structured outputs.

Key capabilities

Query — ask open-ended questions about an image, with an optional reasoning parameter
Caption — generate short, normal, or long descriptions of an image
Point — return coordinates for objects matching a target phrase
Detect — return bounding boxes for objects matching a target phrase

Real-time vision at the edge

Vision workloads like live camera feeds, robotics, content moderation, and interactive agents need answers in milliseconds, not seconds. Moondream 3.1's small active footprint (2B active parameters) pairs well with Workers AI's serverless, globally distributed inference: requests run close to your users, and streaming responses start returning tokens almost immediately.

In our testing, first tokens streamed back in roughly 20–30 ms, and results were fast across every task. The example end-to-end times below (client-observed median, including network round trip) are for a simple, single-subject image. Actual latency depends heavily on the image and how much detail you ask for.

Task	End-to-end (p50)
`query`	~770 ms
`caption`	~480 ms
`point`	~145 ms
`detect`	~160 ms

At these speeds you can call the model inline while handling a request rather than pushing the work to a background queue or a separate service. That opens up use cases where a slow response breaks the experience: moderating user-uploaded images before they are stored, locating an object in a video frame to drive a live overlay, extracting fields from a document during a form submission, or letting an agent inspect a screenshot and decide its next step within a single turn.

Get started

Use Moondream 3.1 through the Workers AI binding (env.AI.run()) or the REST API at /ai/run. You can also use AI Gateway with these endpoints.

For more information, refer to the Moondream 3.1 model page and pricing.

Workers - Cloudflare Drop

Wed, 08 Jul 2026 00:00:00 GMT

Cloudflare Drop ↗ lets you deploy a static site to Cloudflare without requiring a Cloudflare account to get started.

Upload a folder or zip file of static assets (static HTML, CSS, JavaScript, images, and fonts) and get a temporary live preview that stays live for 1 hour. During that window, you can test the site, share the preview URL, or claim the deployment to keep it.

When you are ready to make the deployment permanent, click Claim to sign in or create a Cloudflare account. You can claim the site into an existing Cloudflare account or create a new account for the deployment.

After claiming the site, you can:

Add a domain: Connect an existing domain or purchase a new one for your site.
Enable observability: Monitor your site's performance and usage.
Enable Markdown for Agents: Allow AI agents to access your site's content in Markdown.
Control access: Make your site private and choose who can view it.

Cloudflare One Client - Cloudflare One Client for Windows (version 2026.6.850.0)

Tue, 07 Jul 2026 18:35:35 GMT

A new GA release for the Windows Cloudflare One Client is now available on the stable releases downloads page.

This hotfix addresses a Windows authentication issue in the embedded WebView2 browser. Single sign-on could fail to use the Windows primary account, causing users to be prompted for an interactive sign-in. The embedded authentication browser now allows SSO providers to use the OS primary account when available.

Workflows - Workflows pricing adds per-step billing. Step and storage billing to start no earlier than August 10, 2026.

Tue, 07 Jul 2026 12:00:00 GMT

Workflows pricing now includes per-step billing. Requests and CPU time billing have been enabled since the initial public beta and is not changing.

Workflows adds step billing

A step is each unit of work executed by a Workflow, including step operations such as sleeping or waiting for events.

You can query Workflows analytics, including stepCount for a Workflow instance, with the GraphQL Analytics API.

Steps and storage billing to take effect August 10th, 2026

Starting no earlier than August 10th, 2026, Cloudflare will begin billing for step and storage usage on Workers Paid plans.

Storage pricing has been published since Workflows became generally available and is not changing. Storage is measured as persisted Workflow state in GB-months.

Dimension	Workers Free	Workers Paid
Steps	3,000 included per day	500,000 included per month, then $0.80 per additional 100,000 steps
Storage	1 GB-month included	1 GB-month included, then $0.20 per additional GB-month

Developers on the Workers Free plan will not be charged for steps or storage beyond the included amounts.

Cloudflare will not bill step and storage usage before August 10, 2026.

You can review Workflows usage in the Cloudflare dashboard ↗ before this change takes effect. To reduce costs, consider reducing the number of steps per Workflow or improving the memory efficiency of your stored state.

Refer to the Workflows pricing page for full details.

Access, Cloudflare One - File transfer controls for browser-based RDP (beta)

Tue, 07 Jul 2026 00:00:00 GMT

You can now configure file transfer controls for browser-based RDP with Cloudflare Access, allowing you to restrict whether users can upload or download files between their local machine and the remote Windows server.

This feature is useful for organizations that support bring-your-own-device (BYOD) policies or third-party contractors using unmanaged devices. By restricting file transfers, you can prevent sensitive data from being moved out of the remote session to a user's personal device.

Configuration options

File transfer controls are configured per policy within your Access application, alongside existing text clipboard controls. For each policy, you can select one of the following options:

Client to remote RDP session allowed — Users can upload files from their local machine into the browser-based RDP session.
Remote RDP session to client allowed — Users can download files from the browser-based RDP session to their local machine.
Both directions allowed — Users can upload and download files between their local machine and the browser-based RDP session.
Disable copying/pasting — Users are not allowed to transfer files between their local machine and the browser-based RDP session.

By default, file transfer is denied for new policies. For existing Access applications created before this feature was available, file transfer remains denied.

How it works

To upload, drag files into the browser window or select the settings gear icon on the left side of the RDP session. To download, copy a file in the remote session and select the settings gear to download it, download multiple files as a zip, or print PDFs to a local printer.

This feature is in beta and available on all Zero Trust plans. For more information, refer to File transfer for browser-based RDP.

Browser Isolation, Cloudflare One - Browser Isolation support for authorization proxy endpoints

Tue, 07 Jul 2026 00:00:00 GMT

Browser Isolation now supports Gateway authorization proxy endpoints. You can apply HTTP Isolate policies to traffic routed through authorization proxy endpoints, the same way you can for traffic from the Cloudflare One Client.

Previously, only source IP proxy endpoints supported Browser Isolation, and only with non-identity policies. Because authorization proxy endpoints authenticate users through an identity provider, you can now apply identity-based Isolate policies to PAC file-proxied traffic without requiring the Cloudflare One Client.

To get started, create an authorization proxy endpoint and build an Isolate policy.

Browser Run - New Browser Run endpoint for accessibility trees

Tue, 07 Jul 2026 00:00:00 GMT

Browser Run now supports a standalone /accessibilityTree endpoint, giving agent and automation workflows direct access to the browser's accessibility tree for a rendered webpage.

An accessibility tree is the browser's structured view of a rendered page: roles, names, states, values, and hierarchy. It is useful for accessibility tooling, but also for AI agents and automation workflows that need page structure without the noise of raw HTML or the cost of screenshots.

For AI agents, this means less inference from pixels and less parsing HTML. You can provide the page structure directly, helping agents identify available elements and determine which actions they can take.

With the new /accessibilityTree endpoint, you can request the accessibility tree directly when you only need the semantic structure of a page. If you need multiple page formats in a single API call, you can use the /snapshot endpoint, which also returns Markdown, HTML, and screenshots.

curl -X POST 'https://api.cloudflare.com/client/v4/accounts/<accountId>/browser-run/accessibilityTree' \
  -H 'Authorization: Bearer <apiToken>' \
  -H 'Content-Type: application/json' \
  -d '{
    "url": "https://example.com/"
}'

{
	"success": true,
	"result": {
		"accessibilityTree": {
			"role": "RootWebArea",
			"name": "Example Domain",
			"children": [
				{
					"role": "heading",
					"name": "Example Domain",
					"level": 1
				},
				{
					"role": "link",
					"name": "Learn more"
				}
			]
		}
	}
}

Use interestingOnly to return only semantically meaningful nodes, or root to capture the accessibility tree for a specific subtree.

Refer to the /accessibilityTree documentation for usage examples and supported parameters.

Logs - New WebSocket Analytics Logpush dataset

Tue, 07 Jul 2026 00:00:00 GMT

Enterprise customers can now push per-connection WebSocket analytics to any Logpush destination using the new websocket_analytics dataset. Each log record is emitted when a WebSocket connection closes and includes fields that were previously only available to Cloudflare engineers via internal tooling.

Key fields include:

ConnectionCloseReason — why the connection ended: peerReset, peerNoError, timedOut, upstreamReset, protocolViolation, unspecifiedError, or none.
ConnectionCloseSource — which side initiated the close: upstream, downstream, me, or both.
ConnectionTransportCloseCode — the TLS alert code or TCP-level close code for additional precision.
RayID — correlate WebSocket connection events with your existing HTTP Request logs.

The dataset also includes directional byte counts (BytesSentClient, BytesReceivedClient, BytesSentOrigin, BytesReceivedOrigin), connection timestamps, client IP, colo code, and request metadata from the original WebSocket upgrade.

This data lets you build alerts on connection close patterns — for example, detecting spikes in TCP resets (ConnectionCloseReason == "peerReset") grouped by host and data center — directly in your existing log analysis tools.

For the full list of available fields, refer to WebSocket Analytics.

R2, R2 Data Catalog - R2 Data Catalog warns before you delete data manually

Tue, 07 Jul 2026 00:00:00 GMT

R2 Data Catalog is a managed Apache Iceberg ↗ catalog built directly into your R2 bucket. Iceberg tracks your data through a tree of metadata files, so every insert, update, and delete must go through a catalog transaction. Manually adding, modifying, or deleting objects outside the catalog can leave pointers referencing files that no longer exist, corrupting the table into an inconsistent state that is difficult to recover from.

To help prevent this, the R2 dashboard and Wrangler now warn you when you attempt a manual delete operation on a Data Catalog-enabled bucket.

Dashboard

When you try to delete objects from a bucket that has R2 Data Catalog enabled, the dashboard displays a warning explaining that the operation could leave the catalog in an invalid state, with a link to the documentation for deleting data correctly. You can cancel the operation or choose to proceed anyway.

Wrangler

Wrangler now checks whether a bucket is Data Catalog-enabled before running a delete and warns you before continuing:

Data Catalog is enabled for this bucket. 
Proceeding may leave the data catalog in an invalid state. Continue?

To learn how to safely manage and delete data in your tables, refer to the R2 Data Catalog documentation.

Cloudflare One Appliance, Cloudflare One, Cloudflare WAN - Self-serve registration of Cloudflare One Virtual Appliance in the dashboard

Mon, 06 Jul 2026 00:00:00 GMT

You can now register a Cloudflare One Virtual Appliance and generate its license key directly from the dashboard, without contacting your account team.

On the Connectors page, select Add an appliance and choose Virtual appliance to register a virtual appliance and generate its authentication key.
Use Regenerate authentication key from a virtual appliance connector's menu to rotate its key. The previous key is immediately and irrevocably revoked.
The authentication key is shown only once — copy and store it securely.

This complements the existing API and Terraform self-serve workflow for provisioning virtual appliances. Hardware appliances continue to use the existing account-team fulfillment workflow.

For details, refer to Configure a Cloudflare One Virtual Appliance.

Durable Objects, Workers - Declare Durable Object class lifecycle with `exports`

Sat, 04 Jul 2026 00:00:00 GMT

A new declarative exports field in your Wrangler configuration file replaces the imperative migrations array for managing Durable Object class lifecycle. Instead of writing an ordered list of migration steps with unique tags, you declare each Durable Object class your Worker exports and Cloudflare compares that against what's already deployed to determine what Durable Object state needs to be created, renamed, or deleted.

With legacy migrations, renaming ChatRoom to Room requires retaining both tagged steps:

Before — legacy migrationsjsonc

{
	"migrations": [
		{ "tag": "v1", "new_sqlite_classes": ["ChatRoom"] },
		{
			"tag": "v2",
			"renamed_classes": [{ "from": "ChatRoom", "to": "Room" }],
		},
	],
}

With exports, you instead declare Room as the current class and mark ChatRoom as renamed:

After — declarative exportsjsonc

{
	"exports": {
		"ChatRoom": {
			"type": "durable-object",
			"state": "renamed",
			"renamed_to": "Room",
		},
		"Room": { "type": "durable-object", "storage": "sqlite" },
	},
}

Each entry is keyed by class name. The state field carries the lifecycle (created by default — a live class — plus tombstone states deleted, renamed, and transferred, and the expecting-transfer receiving state for cross-Worker transfers).

Key improvements over the legacy migrations array:

No migration tags. The current exports map is the source of truth — there is no historical chain of v1, v2, v3 entries to maintain.
Structured deployment output. Wrangler reports when it creates, updates, deletes, renames, or transfers Durable Object classes. It also identifies stale configuration entries that are safe to remove. Deployments with no changes or notices do not print this output.
Zero-downtime rename and transfer patterns are first-class. Tombstones may coexist with the source class still in code, enabling a three-deploy rename and a four-deploy cross-Worker transfer without runtime errors during the rollout window.
Cross-Worker safety. When you delete or rename a class, Cloudflare lists every other Worker in your account whose bindings still reference the namespace, so you can redeploy them before the change goes live.

Existing Workers using the legacy migrations array continue to work unchanged. To move to exports, refer to the migration guide. exports and migrations are mutually exclusive within a single Worker.

For the full reference, refer to Durable Object class exports.

Workers - Simpler runtime types with @cloudflare/workers-types v5

Fri, 03 Jul 2026 00:00:00 GMT

We have released version 5 of @cloudflare/workers-types ↗. This release simplifies the package to expose only the latest runtime types.

We still recommend that you generate types for your Worker using wrangler types, but if you want to use the package directly, you can install it with your package manager of choice:

npm i -D @cloudflare/workers-types@latest

yarn add -D @cloudflare/workers-types@latest

pnpm add -D @cloudflare/workers-types@latest

bun add -d @cloudflare/workers-types@latest

The package now exposes two entrypoints:

@cloudflare/workers-types reflects the latest compatibility date, using the latest stable compatibility flags.
@cloudflare/workers-types/experimental reflects APIs behind experimental compatibility flags.

The dated entrypoints, such as @cloudflare/workers-types/2022-11-30 and @cloudflare/workers-types/2023-03-01, are removed. With runtime type generation in Wrangler v4, you can generate these with the wrangler types command to create types locked to your Worker's compatibility date.

For more information, refer to TypeScript language support.

AI Search - Manage AI Search sync jobs with Wrangler CLI

Thu, 02 Jul 2026 00:00:00 GMT

When you connect a data source to your AI Search instance, AI Search runs sync jobs to keep your index up to date with your content. You can now manage those jobs directly from Wrangler.

For example, you can trigger a sync job from your CI/CD or automated pipelines with the jobs create command so your index refreshes when you push a change:

wrangler ai-search jobs create my-instance

This creates an asynchronous sync job that checks for changes in your data source, and sends new, modified, or deleted files to be indexed. The following commands are available:

Command	Description
`wrangler ai-search jobs create`	Trigger a new sync job
`wrangler ai-search jobs list`	List sync jobs for an instance
`wrangler ai-search jobs get`	Get details for a job
`wrangler ai-search jobs cancel`	Cancel a running job
`wrangler ai-search jobs logs`	View log entries for a job

All commands accept --namespace/-n (defaults to default) and --json for structured output that automation and AI agents can parse directly. The list and logs commands also support --page and --per-page for pagination, and cancel prompts for confirmation unless you pass -y/--force.

For full usage details, refer to the AI Search Wrangler commands documentation.

Cache - Cache multiple versions of a URL with Vary

Thu, 02 Jul 2026 00:00:00 GMT

Your origin can serve different responses for the same URL — different languages based on Accept-Language, or different formats based on Accept — by returning a Vary ↗ response header. Cloudflare's cache now honors that header directly in Cache Rules, so the same URL can hold multiple cached versions and each request is matched to the right one. Content that previously had to bypass cache to stay correct can now be cached, following standard HTTP caching behavior ↗.

What changed

Your origin now decides which request headers matter by listing them in its Vary response, and you control how Cloudflare treats each one. When you have enabled Vary using a cache rule and a response includes a Vary header, the request headers listed become part of the cache key.

For each header your origin varies on, choose one of three actions:

Action	Behavior	Best for
`normalize`	Converts equivalent header values to the same cache key value before matching, collapsing redundant versions.	Most `Accept`, `Accept-Language`, and `Accept-Encoding` use cases.
`passthrough`	Uses the raw header value to select the cached version and forwards it to the origin unchanged.	When byte-for-byte differences in the header value should create versions.
`bypass`	Bypasses cache whenever this header name appears in the origin's `Vary` response.	Per-user values, or headers with too many possible values to cache safely.

Benefits

Higher cache hit ratios: normalize treats semantically equivalent headers as one version. For example, Accept-Language: en-US, fr;q=0.8 and Accept-Language: fr;q=0.8, en-GB both resolve to the same cache key, so you serve more requests from cache instead of the origin.
Correct content negotiation: Requests always receive the cached version that matches their headers, so language and format variants stay accurate.
No origin or Worker changes required: If your origin already sends Vary, you configure the behavior entirely in Cache Rules.
Standards-aligned: Cache key calculation follows RFC 9111, and Vary: * continues to bypass cache as required by RFC 9110.

Availability

Vary in Cache Rules is available on all plans (Free, Pro, Business, and Enterprise). For per-request control in Workers subrequests, use the cf.vary property.

Get started

Configure Vary in the Cloudflare dashboard ↗ under Caching > Cache Rules, or through the Rulesets API. To learn how Vary affects cache keys and how each action works, refer to Vary and the Cache Rules Vary setting.

Logs - Updated fields across multiple Logpush datasets in Cloudflare Logs

Thu, 02 Jul 2026 00:00:00 GMT

Cloudflare has updated Logpush datasets:

Updated fields in existing datasets

Gateway DNS (added): AppliedMaxTTL and UpstreamRecordTTLs.
Gateway HTTP (added): Warnings.
HTTP requests (added): CacheLockWaitedMs.

For the complete field definitions for each dataset, refer to Logpush datasets.

Cloudflare Mesh, Cloudflare One - Hostname routing for Cloudflare Mesh

Thu, 02 Jul 2026 00:00:00 GMT

You can now add hostname routes to a Cloudflare Mesh node, in addition to CIDR routes.

Client device
Requests wiki.internal.local
DNS query
Cloudflare Gateway
Returns a token IP, then rewrites the destination to the real private IP.
172.64.128.0/20
Hostname route
Mesh node
Forwards traffic to the host on the local network
↓
Private host
wiki.internal.local · 10.0.0.50

Instead of managing IP ranges, you can attract traffic for a hostname to a Mesh node:

Private hostname (for example, wiki.internal.local) — reach an internal application by name, which is useful when it has an unknown or ephemeral IP. On Mesh you do not need to run a DNS server; a local hosts-file entry on the node is enough, or you can use a Gateway resolver policy for split DNS.
Public hostname (for example, www.example.com) — route that hostname's traffic through the node and egress via the node's public IP.

Go to Mesh ↗

For setup steps, prerequisites, and DNS options, refer to Hostname routes.

Workers - Work across multiple accounts with Wrangler auth profiles

Wrangler CLI now supports auth profiles: named logins that you scope to specific Cloudflare accounts and switch between automatically, based on the directory you are working in.

A profile is a named OAuth login bound to a directory. Commands run in that directory, and its subdirectories, use the matching account — so you can move between accounts without re-running wrangler login.

Use profiles to keep a separate login for each client when working at an agency, or to separate staging and production into different accounts. Pair a profile with an account_id in your Wrangler configuration file so a command cannot reach the wrong account.

# Create a profile for each account, choosing which accounts it can reach
wrangler auth create client-a
wrangler auth activate client-a ~/clients/client-a

wrangler auth create client-b
wrangler auth activate client-b ~/clients/client-b

Use the --profile flag to run a single command with a specific profile:

wrangler deploy --profile personal

In CI and other automated environments, CLOUDFLARE_API_TOKEN still takes precedence over all profiles.

For setup, the resolution order, and the full command reference, refer to Authentication profiles.

Cloudflare One Client - Cloudflare One Client for Linux (version 2026.6.836.0)

Wed, 01 Jul 2026 19:48:17 GMT

A new GA release for the Linux Cloudflare One Client is now available on the stable releases downloads page.

This package is the same release as 2026.6.822.0, with a fix for our RPM package. Previously the repository served a single build to every OS version, so an install could pull a dependency that isn't available on that release. The repository now serves the correct build for each operating system version, so installs automatically pull the dependencies that version requires. Debian and Ubuntu were not affected.

If you installed version 2026.6.822.0 on an RPM-based distribution, we recommend refreshing your repository configuration:

sudo curl -fsSL https://pkg.cloudflareclient.com/cloudflare-warp-ascii.repo | sudo tee /etc/yum.repos.d/cloudflare-warp.repo
sudo dnf clean all
sudo dnf install cloudflare-warp

Access - Fix redirect URL fragment encoding for single-page applications

Wed, 01 Jul 2026 00:00:00 GMT

Access now correctly preserves URL fragment characters (/, ?, =, &, ;) when redirecting users back to an application after login. Previously, these characters were encoded with encodeURIComponent, which mangled fragment-based routes used by single-page applications (SPAs).

For example, an SPA URL like https://app.example.com/#/dashboard?tab=settings&view=advanced would previously redirect to a broken URL after login. This is now handled correctly.

If your SPA users were experiencing broken navigation after authenticating through Access, this fix resolves the issue without any configuration changes.

Access - Independent MFA for infrastructure applications

Wed, 01 Jul 2026 00:00:00 GMT

Access for Infrastructure now supports independent multi-factor authentication (MFA) for SSH connections using YubiKey PIV keys. This adds a hardware-backed second factor to SSH access, ensuring that a compromised device session alone is not sufficient to reach your servers.

With per-application and per-policy configuration, you can enforce PIV key authentication for sensitive usernames (for example, root) while applying different requirements for other usernames. You can also set an MFA session duration to control how often users must re-authenticate.

Enrollment

Users enroll their YubiKey PIV key through the App Launcher. For enrollment instructions and SSH client setup, refer to Enroll a PIV key for infrastructure apps.

Configuration

For setup instructions, refer to Enforce MFA for infrastructure applications.

Bots - New options to manage AI traffic

Wed, 01 Jul 2026 00:00:00 GMT

Not all AI traffic is the same. Now, all customers — including those on the Free plan — can manage AI crawlers based on what they actually do on your site. Cloudflare groups AI traffic into three behaviors you can control independently: Search, Agent, and Training. This lets you keep the automated traffic that sends readers and revenue back to you, while blocking the traffic that only takes from your content.

Each behavior maps to a real use case. Search covers crawlers that index your content so they can answer questions about it later, where you should expect referral traffic or other equitable compensation in return. Agent covers automated activity acting in real time on a person's behalf, such as chat fetch bots and browser-use agents. Training covers crawlers that take your content to train or fine-tune a model. For each preset you can choose to block on all pages, block only on pages that display ads, or choose not to block.

Starting September 15, 2026, new domains onboarding to Cloudflare receive updated defaults: Bots classified as Training or as Agent are blocked on pages that display ads, while Search remains allowed. On that date, multi-purpose crawlers that combine Search and Training will be affected by the new defaults to block Training. All customers can opt out of the new defaults ↗ at any time before September 15.

Bots - More visibility into bot traffic with BotBase and Attribution Business Insights

Wed, 01 Jul 2026 00:00:00 GMT

With Content Independence Day 2026, Enterprise Bot Management customers get two new tools that make bot traffic far easier to see and reason about: BotBase, a searchable directory of every bot Cloudflare tracks, and Attribution Business Insights, a dashboard that shows how much value each crawler sends back to your business.

BotBase is Cloudflare's directory of all known bots and agents, available directly in the dashboard. It shows how Cloudflare classifies each bot by behavior — Search, Agent, Training, and other categories such as Transact, Data Collection, SEO, and Ads Verification — so you can understand why a given crawler is visiting you. You can search and filter the full catalogue, filter your own traffic down to a single bot to investigate its activity on your zone, and copy any bot's detection ID to target it precisely in Security rules. Every tracked bot in BotBase is also published in Cloudflare Radar's bots and agents directory ↗.

Attribution Business Insights is built for content owners and business decision-makers who want to know which bots help or harm their business, without reading rule syntax. The dashboard reports crawl-to-referral ratios both site-wide and per bot operator — comparing how often a company crawls your content against how many visitors it actually refers back — over the last 24 hours, 7 days, or 30 days. Each operator is labeled with Cloudflare's updated classification and an action status of Allowed, Blocked, or Partially blocked, giving stakeholders a shared, at-a-glance view of the AI traffic reaching your site.

Containers - Use Google Artifact Registry images with Containers

Wed, 01 Jul 2026 00:00:00 GMT

Containers now support Google Artifact Registry ↗ images. After you configure credentials, you can use a fully qualified Google Artifact Registry image reference in your Wrangler configuration instead of first pushing the image to Cloudflare Registry.

Provide the service account email with --gar-email and pipe the service account JSON key through stdin:

cat <PATH_TO_KEY> | npx wrangler containers registries configure <REGION>-docker.pkg.dev --gar-email=<SERVICE_ACCOUNT_EMAIL> --secret-name=<SECRET_NAME>

{
  "$schema": "./node_modules/wrangler/config-schema.json",
  "containers": [
    {
      "image": "<REGION>-docker.pkg.dev/<PROJECT_ID>/<REPOSITORY>/<IMAGE>:<TAG>"
    }
  ]
}

# Example: us-central1-docker.pkg.dev/my-project/my-repo/my-image:latest
[[containers]]
image = "<REGION>-docker.pkg.dev/<PROJECT_ID>/<REPOSITORY>/<IMAGE>:<TAG>"

Only *-docker.pkg.dev hosts are supported. To configure credentials, refer to Use private Google Artifact Registry images.

For more information, refer to Image management.

Cloudflare Images - Images binding is now billed per unique transformation

Wed, 01 Jul 2026 00:00:00 GMT

The Images binding is now billed per unique transformation, matching the model already used for URL-based transformations. Repeat requests for the same combination of source image and parameters within the same calendar month are counted only once.

Previously, every call to the binding counted as a separate transformation regardless of whether the image or parameters were unique. With this change, you can call the binding on hot paths without paying for each individual request.

Calls to .info() are no longer billed.

For more information, refer to Images pricing and the Images binding documentation.

Vectorize - Reduced end-to-end latency for vector changes

Wed, 01 Jul 2026 00:00:00 GMT

We have greatly improved the throughput of the Vectorize write-ahead log (WAL) ↗. As a result, we have significantly reduced the end-to-end latency for a vector change to become queryable: median latency has dropped from 2 minutes to under 30 seconds, and p99 latency from 5 minutes to under 2 minutes.

This means inserts, upserts, and deletes are reflected in query results faster, improving the freshness of semantic search, recommendation, and retrieval-augmented generation (RAG) workloads. You do not need to change your code or configuration to benefit from this improvement.

For more information, refer to the Vectorize documentation.

WAF - WAF Release - 2026-07-01

Wed, 01 Jul 2026 00:00:00 GMT

Gateway, Cloudflare One, Cloudflare Fundamentals - New permissions and roles for Gateway policies and lists

Tue, 30 Jun 2026 00:00:00 GMT

You can now assign granular, resource-scoped roles for Cloudflare Gateway firewall policies and Zero Trust lists. Administrators can delegate access to specific policy types or list management without granting account-wide or product-wide control.

What is new

When you add a member or create a permission policy, the following resource-scoped roles are now available:

Role	Description
Zero Trust Gateway Firewall Policies Admin	Can view and edit all Gateway firewall policies, including DNS, HTTP, and Network policies.
Zero Trust Gateway DNS Policies Admin	Can view and edit Gateway DNS policies.
Zero Trust Gateway HTTP Policies Admin	Can view and edit Gateway HTTP policies.
Zero Trust Gateway Network Policies Admin	Can view and edit Gateway Network policies.
Zero Trust Gateway Egress Policies Admin	Can view and edit Gateway Egress policies.
Zero Trust Gateway Resolver Policies Admin	Can view and edit Gateway Resolver policies.
Zero Trust Gateway Policies Admin	Can view and edit all Gateway policies.
Zero Trust Gateway Policies Read	Can view all Gateway policies.
Zero Trust Gateway Read Only	Can view all Gateway resources.
Zero Trust DNS Locations Admin	Can view and edit DNS locations.
Zero Trust Proxy Endpoints Admin	Can view and edit Gateway Proxy Endpoints.
Zero Trust Account Lists Admin	Can view and edit all Gateway and Access lists.
Zero Trust Account Lists Read	Can view all Gateway and Access lists.

These roles allow you to:

Grant a network engineer write access to Network policies only, without exposing DNS or HTTP policy configuration.
Allow a security analyst to view all Gateway policies in read-only mode for auditing purposes.
Delegate list management to a team that maintains block and allow lists without giving them access to policy configuration.

You can also now assign Resource-scoped roles. These roles are complementary to existing account-level roles, and allow you to grant access to a specific resource, like an individual Gateway policy or Cloudflare One list. Existing account-level roles continue to work. A member with the Cloudflare Gateway or Cloudflare Zero Trust role retains full access to all Gateway resources. This ensures backward compatibility for existing automation and API tokens.

Get started

Review the resource-scoped roles on the Cloudflare role reference.

Logs - Account-scoped firewall events dataset in Logpush

Tue, 30 Jun 2026 00:00:00 GMT

Cloudflare Logpush now supports firewall events as an account-scoped dataset. Configure a single Logpush job at the account level to receive firewall events for every zone in the account, instead of creating and maintaining a separate job per zone.

The dataset includes a new ZoneName field so you can identify which zone each event came from when consuming logs in your downstream pipeline.

What's available

A new account-scoped firewall_events dataset, configurable via the Logpush API or the Cloudflare dashboard.
The same fields and filter expressions supported by the existing zone-scoped firewall events dataset, plus the new ZoneName field.
Support for all existing Logpush destinations.

Workers, Durable Objects - Track memory usage for Workers and Durable Objects in the dashboard

Tue, 30 Jun 2026 00:00:00 GMT

You can now monitor how much memory your Workers and Durable Objects consume across invocations with the new Memory Usage chart in the Workers Metrics tab, broken down by P50, P90, P99, and P999 percentiles.

Memory usage measures the V8 isolate memory at the time of each invocation, subject to the 128 MB per-isolate limit — a single isolate can handle many concurrent requests and shares memory across them.

Use the Memory Usage chart to:

Track memory trends — Spot gradual increases that may indicate a memory leak before they cause Exceeded Memory errors.
Correlate with deployments — Deployment markers on the chart help you identify whether a new version introduced a memory regression.
Right-size your Worker — Understand your baseline memory footprint and how much headroom you have before hitting the 128 MB limit.

For Durable Objects, memory usage reflects the in-memory state an object holds (class properties, caches, active WebSocket connections), which persists across invocations until the object is hibernated or evicted. This state is not preserved across eviction, hibernation, or a crash, so persist anything important to storage.

To view memory usage, open the Metrics tab for your Worker ↗ or Durable Object namespace ↗. For Durable Objects, you can filter by DO ID or name to drill down into memory usage for a specific object. You can also query memory usage programmatically via the GraphQL Analytics API using the workersInvocationsAdaptive dataset — the quantiles.memoryUsageBytesP50 through quantiles.memoryUsageBytesP999 fields return percentile values in bytes.

For local memory debugging, you can also profile memory with DevTools to take heap snapshots and identify specific objects causing high memory usage.

Cloudflare One Client - Cloudflare One Client for Windows (version 2026.6.822.0)

Mon, 29 Jun 2026 20:05:45 GMT

A new GA release for the Windows Cloudflare One Client is now available on the stable releases downloads page.

This release introduces multiple features from our previous beta release into stable release, including:

The client now applies DNS search suffixes configured in your device profile / network policy. Administrators can push a list of DNS search domains that the client appends to single-label queries, alongside any system-configured suffixes. See DNS search suffixes for details.
Added mandatory authentication. When enabled via MDM, the Cloudflare One Client blocks all Internet traffic from the moment the machine boots until the user authenticates, closing the visibility gap on newly deployed devices and during re-authentication. See the announcement blog and documentation for details.
Upgraded security of device registration to be hardware-backed. Registration tokens can now be generated in the TPM (with TPM 2.0+) whenever it is available to provide stronger protection against device impersonation. See Hardware-backed registration for details.
Added a local-file signal source for Emergency Disconnect. In addition to the existing HTTPS polling mechanism, administrators can now configure WARP to monitor for a file on disk; the presence of the file triggers an emergency disconnect even if both Cloudflare and your own infrastructure are unreachable. Either signal being asserted triggers disconnect; both must be cleared for normal operation to resume.
Added new warp-cli debug commands for interactive connection diagnosis. See Extra debug logging for details.
The local DNS proxy now supports DNSSEC passthrough. DNSSEC-signed responses are forwarded to the application intact (including DO/AD bits and RRSIG records), so applications that validate DNSSEC locally — including resolvers and the dig/drill tooling — work correctly through the client.
Added a new MDM format for organization-wide settings, including a cleaner way to configure the compliance environment (e.g. FedRAMP). The previous per-configuration approach still works, but the new format is now recommended. See the updated Cloudflare One MDM documentation for details.
Added support for dashboard-managed client version deployments. Administrators can now upgrade or downgrade the client version on enrolled devices directly from the Zero Trust dashboard. See Client version assignments for details.

Additional Changes and improvements

Starting with 2026.6.822.0, the client unifies all API requests under the api.devices.cloudflare.com SNI, where previously both zero-trust-client.cloudflareclient.com and notifications.cloudflareclient.com were used. Review Cloudflare One Client with firewall to ensure systems that rely on SNI inspection do not block the API traffic. The behavior of previous client versions is unaffected.
Client Certificate device-posture checks now support template variables (e.g. ${serial_number}, ${device_uuid}) in the Subject Alternative Name field. Previously only the Common Name field accepted variables, which broke posture rules that pinned identity to a SAN entry.
Improved accessibility by using high contrast colors and more defined color boundaries when high contrast is enabled in Windows Accessibility settings.
Path MTU Discovery (PMTUD) is now enabled by default.
The UseWebView2 registry value (HKLM\SOFTWARE\Cloudflare\CloudflareWARP\UseWebView2 = y) is once again honored by the new GUI for authentication, so administrators who prefer the embedded WebView2 browser for sign-in can opt back in. This setting was effectively ignored in the previous release; the default browser was always used. This key is now also honored for re-authentications.
Fixed a crash in the authentication browser when navigating to a site that prompts for browser permissions (microphone, camera, notifications, etc.). The same fix had previously landed for the captive-portal browser; this extends it to the auth browser.
Fixed an issue in proxy mode where hostnames containing underscores (e.g. ai_app.com) were rejected, breaking apps that depend on such hostnames (notably ChatGPT sandbox apps). The local proxy now accepts underscore-containing hostnames in CONNECT requests.
Fixed an issue where DNS queries would fail after the connection was idle, requiring users to retry.
Fixed a high CPU issue when the device wakes from sleep.
Users can now register with team names in any case format without errors.
New UI fixes
- Fixed an issue where users with invalid MDM configurations were returned to the onboarding screen after successful authentication.
- Added a re-auth button and banner to the home screen so users don't miss it when their session expires.
- Added clear error messaging when the Cloudflare certificate needs to be installed.
- Brought back support for pausing the tunnel when connected to user-specified Wi-Fi networks for consumer users.
- New client UI now surfaces Split tunnel configuration and Local Domain Fallback configuration.
- Added ability to configure proxy mode for consumer users.
- Added back the option to quit for consumer users.

Known issues

Single sign-on in the embedded WebView2 authentication browser may fail to use the Windows primary account, prompting for an interactive sign-in.
An error indicating that Microsoft Edge can't read and write to its data directory may be displayed during captive portal login; this error is benign and can be dismissed.
In rare cases, a registration may hang at "Checking your organization configuration" due to IPC errors. A system reboot should resolve the error, allowing registration to proceed.
Windows ARM may prompt the user to close running applications while trying to install this version. Simply click "Ok" with the default highlighted option.

Cloudflare One Client - Cloudflare One Client for macOS (version 2026.6.822.0)

Mon, 29 Jun 2026 20:05:45 GMT

A new GA release for the macOS Cloudflare One Client is now available on the stable releases downloads page.

This release introduces multiple features from our previous beta release into stable release, including:

The client now applies DNS search suffixes configured in your device profile / network policy. Administrators can push a list of DNS search domains that the client appends to single-label queries, alongside any system-configured suffixes. See DNS search suffixes for details.
Upgraded security of device registration to be hardware-backed. Registration tokens can now be generated in the Secure Enclave whenever available to provide stronger protection against device impersonation. See Hardware-backed registration for details.
Added a local-file signal source for Emergency Disconnect. In addition to the existing HTTPS polling mechanism, administrators can now configure WARP to monitor for a file on disk; the presence of the file triggers an emergency disconnect even if both Cloudflare and your own infrastructure are unreachable. Either signal being asserted triggers disconnect; both must be cleared for normal operation to resume.

Improved accessibility by using high contrast colors and more defined color boundaries when high contrast is enabled in the macOS Display settings.
Path MTU Discovery (PMTUD) is now enabled by default.
Fixed the in-client captive-portal browser rendering a blank "Success" page on some airline Wi-Fi networks. The browser now more consistently loads the airline's real portal page so users can complete sign-in from inside the client instead of having to open a separate browser.
Fixed an issue in proxy mode where hostnames containing underscores (e.g. ai_app.com) were rejected, breaking apps that depend on such hostnames (notably ChatGPT sandbox apps). The local proxy now accepts underscore-containing hostnames in CONNECT requests.
Fixed an issue where DNS queries would fail after the connection was idle, requiring users to retry.
Users can now register with team names in any case format without errors.
New UI fixes

- New client UI now surfaces Split tunnel configuration and Local Domain Fallback configuration.
- Added ability to configure proxy mode for consumer users.
- Added back the option to quit for consumer users.

Known issues

Registration may hang at "Checking your organization configuration" due to IPC errors. A system reboot should resolve the error, allowing registration to proceed.
When deploying with Microsoft Intune, the client may be repeatedly reinstalled because Intune adds the client's embedded framework bundles to its install-detection list, and those frameworks cannot be detected as installed on their own. See Repeated reinstalls on macOS with Microsoft Intune for the workaround.

Cloudflare One Client - Cloudflare One Client for Linux (version 2026.6.822.0)

For RHEL deployments, this release introduces a dependency on the Extra Packages for Enterprise Linux repository (EPEL). The EPEL repository provides packages that support the captive portal detection’s in-app browser authentication and system tray icon. See Getting started with EPEL for instructions on enabling EPEL.

Known issues

Registration may hang at "Checking your organization configuration" due to IPC errors. A system reboot should resolve the error, allowing registration to proceed.

Workers - Workers fetch requests now support cf.vary

Sun, 28 Jun 2026 00:00:00 GMT

Workers fetch() requests now support the cf.vary request option. Use cf.vary to control how Cloudflare caches origin responses with a Vary header for a single subrequest.

src/index.jsjs

export default {
	async fetch(request) {
		return fetch(request, {
			cf: {
				vary: {
					default: { action: "bypass" },

Agents, Workers - Agents SDK adds background sub-agents and a unified turn entry point

Fri, 26 Jun 2026 00:00:00 GMT

The latest release of the Agents SDK ↗ makes it easier to run long work in the background, drive turns through one entry point, and keep chat agents working through deploys, evictions, and reconnects.

This release adds first-class detached (background) sub-agent runs with live progress and durable milestones, a single runTurn turn-admission entry point, and a large round of recovery and reliability fixes that continue converging @cloudflare/think and @cloudflare/ai-chat onto one model.

Background sub-agents with progress and milestones

runAgentTool can now dispatch a sub-agent without blocking the calling turn. A detached run returns a handle immediately and is owned by a durable, eviction-surviving backbone instead of being abandoned when the dispatching turn ends.

class OrdersAgent extends Think {
	async startImport(input) {
		// Fire-and-forget, or wire a durable completion callback
		// (by method name, like schedule()):
		await this.runAgentTool(ImportAgent, {
			input,
			detached: { onFinish: "onImportDone", maxBudgetMs: 60 * 60 * 1000 },
		});
	}

	// result.status: "completed" | "error" | "aborted" | "interrupted"
	async onImportDone(run, result) {}
}

class OrdersAgent extends Think {
	async startImport(input) {
		// Fire-and-forget, or wire a durable completion callback
		// (by method name, like schedule()):
		await this.runAgentTool(ImportAgent, {
			input,
			detached: { onFinish: "onImportDone", maxBudgetMs: 60 * 60 * 1000 },
		});
	}

	// result.status: "completed" | "error" | "aborted" | "interrupted"
	async onImportDone(run, result) {}
}

Highlights:

Durable, exactly-once-on-the-happy-path completion via a warm fast path plus a self-scheduling reconcile backbone that survives eviction and deploys.
Bounded. An absolute maxBudgetMs ceiling (default 24h) and cancelAgentTool(runId) keep abandoned runs from holding a concurrency slot forever.
detached: { notify: true } lets a finished background run inject a message back into the chat so the model reacts to the result — no hand-wired onFinish needed.

Sub-agents can also report mid-run progress that rides their own turn stream back to the parent's connected clients:

// Inside the child sub-agent:
await this.reportProgress({
	fraction: 0.6,
	phase: "deploying",
	message: "Generating menu page…",
});

// Inside the child sub-agent:
await this.reportProgress({
	fraction: 0.6,
	phase: "deploying",
	message: "Generating menu page…",
});

Progress surfaces on AgentToolRunState.progress via useAgentToolEvents, so a background-runs tray can render a live bar without drilling in, and the latest snapshot is persisted for inspection after eviction. Naming a milestone promotes a signal to a durable, replayable row, and detached: { onMilestones } can surface a milestone as a synthetic chat message ("narrate" for a cheap status line, or "react" to drive a model turn).

One entry point for turns: `runTurn`

@cloudflare/think adds a public runTurn(options) facade that unifies turn admission behind a single mode:

await this.runTurn({ mode: "wait", messages }); // saveMessages / continueLastTurn
await this.runTurn({ mode: "submit", messages }); // durable submitMessages
await this.runTurn({ mode: "stream", messages }); // chat()

await this.runTurn({ mode: "wait", messages }); // saveMessages / continueLastTurn
await this.runTurn({ mode: "submit", messages }); // durable submitMessages
await this.runTurn({ mode: "stream", messages }); // chat()

stream mode accepts array and function inputs to match wait mode, and all entry points now route through a shared internal admission path that throws a clear error on nested blocking admissions that previously could deadlock.

Recovery and reliability

A large part of this release continues hardening recovery and converging @cloudflare/think and @cloudflare/ai-chat onto one model:

Stream stall watchdog. AIChatAgent can detect and recover from a hung model/transport stream via the opt-in chatStreamStallTimeoutMs watchdog. With chatRecovery enabled the stall routes into the same bounded-recovery machinery a deploy or eviction uses; otherwise it surfaces as a terminal stream error so the spinner clears.
Interrupted tool-call repair. AIChatAgent now repairs a transcript with a dead server-tool call before re-entering inference (parity with @cloudflare/think), so a recovered turn no longer fails with AI_MissingToolResultsError. An overridable repairInterruptedToolPart(part) hook lets apps customize the repaired shape.
Stuck status after reconnect. Fixed AI SDK status getting stuck when a reconnect races a turn that has been accepted but has not started streaming yet, so the UI now renders the in-flight turn instead of settling on ready.
Live "recovering…" on connect. AIChatAgent now replays the recovering status to a client that connects mid-recovery, so useAgentChat's isRecovering reflects in-progress recovery immediately instead of appearing frozen.
Terminal connection failures. The client stops reconnecting on terminal WebSocket close events and exposes them via connectionError / onConnectionError on AgentClient, useAgent, and useAgentChat.
Agent-tool child recovery. A healthy long-running sub-agent run is no longer abandoned as interrupted after a deploy (both @cloudflare/think and AIChatAgent).
Workflows from sub-agent facets. Agent Workflows can now start from sub-agent facets, with callbacks and Workflow RPC routed back to the originating facet.
Plus forward-progress crediting convergence, broadcast-first give-up ordering, an event-driven auto-continuation barrier, and structured row-size compaction in AIChatAgent.

Other improvements

Shared chat React core. A new agents/chat/react entry exposes useAgentChat, transport helpers, and shared wire types, with syncMessagesToServer for server-authoritative transcript storage. @cloudflare/think/react and @cloudflare/ai-chat/react are now thin wrappers over it.
Optional ai peer. The root agents and @cloudflare/codemode runtimes no longer reference AI SDK types, so they bundle without ai / zod installed; AI-specific entry points still require the peer when imported. just-bash likewise moves to an optional peer used only by the skills bash runner.
Code Mode. The default DynamicWorkerExecutor timeout increases from 30s to 60s, executions now dispose the dynamically-loaded Worker and its RPC stub after each run (fixing a flaky isolate-shutdown assertion), connector imports are cleaned up, and the outer MCP tool-call context is passed to openApiMcpServer request callbacks.
Voice. Voice turns now support AI SDK fullStream responses (and warn when textStream is used).
MCP. McpAgent server-to-client requests can now be sent from callbacks that do not inherit the agent's async context, including callbacks reached through Worker Loader RPC.
Experimental: server actions and channels. This release lays groundwork for guarded server actions (action() / getActions() with a durable replay ledger and approvals) and a unified channels surface (configureChannels(), deliverNotice()). Both are experimental and their APIs may change, so we don't recommend depending on them yet.

Cloudflare One, Access - Service token support for MCP server portals

Fri, 26 Jun 2026 00:00:00 GMT

You can now connect autonomous agents and bots to an MCP server portal using an Access service token. Service token sessions can reach upstream MCP servers through the portal without a browser-based OAuth flow.

To set this up:

Add a Service Auth policy that matches your service token to the portal's Access application.
Add a Service Auth policy that matches the same token to each linked MCP server's Access application.
Turn Require user auth off (on_behalf: false) for each linked server so the portal uses the admin credential instead of a per-user OAuth grant.

The bot connects with CF-Access-Client-Id and CF-Access-Client-Secret headers and sees the tools from every linked server it is authorized for. Servers that still require per-user OAuth are excluded from service token sessions because a service token cannot complete a per-user OAuth grant.

For step-by-step setup, refer to Connect with a service token.

Durable Objects, Workers - New `us` jurisdiction for Durable Objects

Fri, 26 Jun 2026 00:00:00 GMT

Durable Objects now supports a us jurisdiction, letting you create Durable Objects that only run and store data within the United States. Use the us jurisdiction when you need to keep a Durable Object's compute and storage inside the United States to meet data residency requirements.

Create a namespace restricted to the us jurisdiction the same way as any other jurisdiction:

// Worker
export default {
	async fetch(request, env) {
		const usSubnamespace = env.MY_DURABLE_OBJECT.jurisdiction("us");
		const stub = usSubnamespace.getByName("general");
		return stub.fetch(request);
	},
};

Workers may still access Durable Objects constrained to the us jurisdiction from anywhere in the world. The jurisdiction constraint only controls where the Durable Object itself runs and persists data.

For the full list of supported jurisdictions, refer to Data location — Restrict Durable Objects to a jurisdiction.

Cloudflare Fundamentals - Search API tokens by name

Thu, 25 Jun 2026 00:00:00 GMT

You can now search API tokens by name, making it easier to find specific tokens across large token lists without manually paginating.

What's new

Dashboard search: Both account API tokens ↗ and user API tokens ↗ pages now include a search bar. Type a name to filter results.
API search support: The /user/tokens and /accounts/{account_id}/tokens endpoints now accept a name query parameter to filter tokens by name.

For more information, refer to Create an API token and Account API tokens.

Durable Objects, Workers - Test Durable Object eviction with new cloudflare:test helpers

Thu, 25 Jun 2026 00:00:00 GMT

The @cloudflare/vitest-pool-workers package now includes evictDurableObject and evictAllDurableObjects test helpers, exported from cloudflare:test.

These helpers let you test how a Durable Object behaves across evictions, simulating the production lifecycle where an idle Durable Object can be evicted from memory.

For more context, refer to Lifecycle of a Durable Object.

import { evictDurableObject, evictAllDurableObjects } from "cloudflare:test";
import { env } from "cloudflare:workers";

const id = env.COUNTER.idFromName("my-counter");
const stub = env.COUNTER.get(id);

// Evict the Durable Object instance pointed to by a specific stub
await evictDurableObject(stub);

// Close WebSockets instead of hibernating them
await evictDurableObject(stub, { webSockets: "close" });

// Evict all currently-running Durable Objects in evictable namespaces
await evictAllDurableObjects();

These helpers are available in @cloudflare/vitest-pool-workers@0.16.20 and later.

Learn more in the Test APIs reference and the Testing Durable Objects guide.

Cloudflare One Client - Cloudflare One Client for macOS (version 2026.6.782.1)

Wed, 24 Jun 2026 18:35:32 GMT

A new Beta release for the macOS Cloudflare One Client is now available on the beta releases downloads page.

This beta release introduces upgraded security of device registration to be hardware-backed. Registration tokens can now be generated in the Secure Enclave whenever available to provide stronger protection against device impersonation.

Additional changes and improvements

This release also introduces multiple fixes and improvements including:

Improved accessibility by using high contrast colors and more defined color boundaries when high contrast is enabled in the macOS Display settings.
Path MTU Discovery (PMTUD) is now enabled by default.
Fixed an issue where DNS queries would fail after the connection was idle, requiring users to retry.
Users can now register with team names in any case format without errors.
New UI fixes
- Fixed an issue where users with invalid MDM configurations were returned to the onboarding screen after successful authentication.
- Added a re-auth button and banner to the home screen so users don't miss it when their session expires.
- Added clear error messaging when the Cloudflare certificate needs to be installed.
- Brought back support for pausing the tunnel when connected to user-specified Wi-Fi networks for consumer users.
- New client UI now surfaces Split tunnel configuration and Local Domain Fallback configuration.
- Added ability to configure proxy mode for consumer users.
- Added back the option to quit for consumer users.

Known issues

Registration may hang at "Checking your organization configuration" due to IPC errors. A system reboot should resolve the error, allowing registration to proceed.

AI Search - Control AI Search similarity cache freshness

Wed, 24 Jun 2026 00:00:00 GMT

AI Search now gives you more control over similarity cache freshness. Similarity cache helps reduce latency and inference cost by reusing responses for semantically similar queries.

With these updates, you can choose how long responses are eligible for reuse and clear cached responses when they may be stale.

Cache duration now defaults to 48 hours

Previously, AI Search cached responses for a fixed duration of 30 days. Cached responses now use the instance's cache_ttl setting, and the default is 48 hours.

You can set cache_ttl when creating or updating an instance to choose a cache duration from 10 minutes to 6 days.

Use a shorter TTL when your source content changes frequently and freshness is more important. Use a longer TTL when your content is stable and you want more cache reuse.

For example, set cache_ttl to 518400 to retain cached responses for 6 days:

{
	"cache_ttl": 518400
}

Purge cached responses

You can also purge all cached responses for an instance on demand. Purging cached responses does not delete indexed content or source files.

It prevents AI Search from reusing previous cached responses, so subsequent similar queries generate fresh answers and repopulate the cache.

curl -X POST "https://api.cloudflare.com/client/v4/accounts/$ACCOUNT_ID/ai-search/instances/$INSTANCE_NAME/purge_cache" \
  -H "Authorization: Bearer $CLOUDFLARE_API_TOKEN"

You can also purge cached responses from the instance settings page in the Cloudflare dashboard.

Refer to similarity cache for the full list of supported cache_ttl values and more details about cache behavior.

Audit Logs - Audit Logs v2 — Organization-level audit logs in Cloudflare dashboard

Wed, 24 Jun 2026 00:00:00 GMT

You can now, as an Organization Super Administrator, view organization-level audit logs in the Cloudflare dashboard, in addition to the existing API access.

Organization audit logs help you monitor activity across your organization. You can see who performed an action, what changed, when it happened, how it was performed, and whether it succeeded or failed.

You can filter and search logs by actor, action, result, resource, request details, and timestamp. Use these logs to troubleshoot changes, investigate unexpected access, and support security or compliance workflows.

If you are viewing account-level audit logs and the account belongs to an organization where you are an Organization Super Administrator, select View Organization Audit Logs to open the parent organization's audit logs.

To get started, go to Organizations, select your organization, then go to Manage Organization > Audit Logs.

For more information, refer to the Audit Logs documentation.

Logs - New WebSocket Analytics Logpush dataset and updated fields

Wed, 24 Jun 2026 00:00:00 GMT

Cloudflare has updated Logpush datasets:

New datasets

WebSocket Analytics: A new dataset with fields including BytesReceivedClient, BytesReceivedOrigin, BytesSentClient, BytesSentOrigin, ClientASN, ClientIP, ClientRequestHost, ClientRequestPath, ClientRequestUserAgent, ColoCode, ConnectionCloseReason, ConnectionCloseSource, ConnectionID, ConnectionTransportCloseCode, EdgeEndTimestamp, EdgeStartTimestamp, and RayID.

Updated fields in existing datasets

Firewall events (added): ZoneName. The Firewall events dataset is now also available for account-scope Logpush, in addition to the existing zone scope.
Email Security Alerts (added): BCC, DKIMResult, DMARCPolicy, DMARCResult, and SPFResult.

For the complete field definitions for each dataset, refer to Logpush datasets.

Radar - Precise IP location and richer AS details on the Cloudflare Radar IP page

Wed, 24 Jun 2026 00:00:00 GMT

Radar now plots your IPv4 and IPv6 locations on the IP page ↗, shows the Cloudflare data centers serving your connection, and includes more detail about the autonomous system (AS) your primary IP belongs to.

Your IP location on the map

The map of your connection now shows:

IP location markers — The primary IP will show as a red marker. When both IP addresses do not geolocate to the same place, a second marker will appear in blue with a note explaining why IPv4 and IPv6 can resolve to different locations.
Cloudflare data center markers — Cloudflare data centers now show as orange dots on the map and the one you are connected to is highlighted.
Data center connectors — Each line connects your IP markers to their respective data centers.

Due to the data policies of our geolocation provider, this detailed location is only available for your own IP. Other IP addresses keep the current country-level view.

Extended AS information

The AS card on the IP page now shows additional detail about the network an IP belongs to — including alternate names, the operator website, and an estimate of the AS user population — alongside the AS number and country.

Visit the Cloudflare Radar IP page ↗ to explore more details about your IP.

Workflows - Workflows rollback handlers now include step context

Tue, 23 Jun 2026 12:00:00 GMT

Workflows makes it easier to build reliable multi-step applications that can recover when downstream systems fail. Rollback handlers now receive the original step context via a ctx object for the step being rolled back. This includes ctx.step.name, ctx.step.count, ctx.attempt, and the step config with defaults applied.

The step configuration includes the retry and timeout settings used for that step, so you can customize your step recovery logic according to those fields.

await step.do(
	"create charge",
	async () => {
		const charge = await createCharge();
		return { chargeId: charge.id };
	},
	{
		rollback: async ({ ctx, output, error }) => {
			// `output` is the value returned by the step being rolled back.
			const { chargeId } = output as { chargeId: string };
			await refundCharge(chargeId, {
				// `ctx` is the original step context, including step name, count, attempt, and config.
				reason: `${ctx.step.name}: ${error.message}`,
			});
		},
		rollbackConfig: {
			// `rollbackConfig` controls retries and timeout for the rollback handler.
			retries: { limit: 3, delay: "30 seconds", backoff: "linear" },
			timeout: "5 minutes",
		},
	},
);

Refer to rollback options to learn more.

Data Localization Suite - Regionalized IP Bindings for Regional Services

Tue, 23 Jun 2026 00:00:00 GMT

Regional Services now supports Regionalized IP Bindings, letting you regionalize traffic at the IP layer for prefixes you bring to Cloudflare through Bring Your Own IP (BYOIP).

Where Regional Hostnames regionalize traffic by hostname, Regionalized IP Bindings let you bind a CIDR from one of your prefixes to a region — ideal for address-map deployments and any service you address by IP rather than hostname. Cloudflare then terminates TLS and processes traffic to those addresses only within the data centers in that region.

Regionalized IP Bindings requires the Regional Services and Regional Services for BYOIP entitlements. Contact your account team to enable them.

To get started, refer to Regionalized IP Bindings.

Speed - Cloudflare AMP/SXG is now end of life.

Tue, 23 Jun 2026 00:00:00 GMT

Cloudflare Accelerated Mobile Pages (AMP) and Signed Exchanges (SXG) support has reached end of life. The features have been disabled since October 2025, so customers who had them configured should see no change to their traffic.

Customers will no longer be able to configure AMP/SXG through API or rulesets. The Zone API will start throwing errors. Rulesets with the SXG configuration will fail to save until SXG has been removed.

WAF - WAF Release - 2026-06-23

Tue, 23 Jun 2026 00:00:00 GMT

This week's release introduces new managed protection to address a critical pre-authentication OS command injection vulnerability in Ivanti Sentry (CVE-2026-10520).

Key Findings

CVE-2026-10520: An OS command injection vulnerability in Ivanti Sentry allows remote, unauthenticated attackers to execute arbitrary system commands with root privileges. The flaw stems from improper sanitization of input strings parsed during internal configuration handling.

Ruleset	Rule ID	Legacy Rule ID	Description	Previous Action	New Action	Comments
Cloudflare Managed Ruleset		N/A	Ivanti Sentry - Command Injection - CVE:CVE-2026-10520	Log	Block	This is a new detection.

R2 SQL - R2 SQL now supports window functions, DISTINCT, and set operations

Mon, 22 Jun 2026 00:00:00 GMT

R2 SQL now supports window functions, SELECT DISTINCT, set operations, and additional aggregates, making it easier to write analytical queries without preprocessing your data elsewhere.

R2 SQL is Cloudflare's serverless, distributed SQL engine for querying Apache Iceberg ↗ tables stored in R2 Data Catalog.

New capabilities

Window functions — ROW_NUMBER, RANK, DENSE_RANK, PERCENT_RANK, CUME_DIST, NTILE, LAG, LEAD, FIRST_VALUE, LAST_VALUE, NTH_VALUE, and aggregates with an OVER (...) clause, including PARTITION BY and explicit frames
QUALIFY — filter rows based on a window function result
DISTINCT — SELECT DISTINCT, DISTINCT ON (...), and the DISTINCT modifier on aggregates such as COUNT(DISTINCT ...)
Set operations — UNION, UNION ALL, INTERSECT, and EXCEPT
Grouping extensions — GROUPING SETS, ROLLUP, and CUBE
Exact aggregates — MEDIAN, PERCENTILE_CONT, ARRAY_AGG, and STRING_AGG

Examples

Rank rows with a window function

SELECT customer_id, region,
       ROW_NUMBER() OVER (PARTITION BY region ORDER BY total_amount DESC) AS rank_in_region
FROM my_namespace.sales_data

Filter with QUALIFY

SELECT customer_id, region, total_amount
FROM my_namespace.sales_data
QUALIFY ROW_NUMBER() OVER (PARTITION BY region ORDER BY total_amount DESC) <= 3

Combine tables with a set operation

SELECT customer_id FROM my_namespace.sales_data
EXCEPT
SELECT customer_id FROM my_namespace.archived_sales

The named WINDOW clause is not supported — inline the OVER (...) specification at each call site. For the full syntax reference, refer to the SQL reference. For supported features and performance guidance, refer to Limitations and best practices.

Cloudflare Mesh, Cloudflare Tunnel, Cloudflare WAN, Cloudflare One - Manage all your routes from one page in the dashboard

Fri, 19 Jun 2026 00:00:00 GMT

The Routes page in the Cloudflare dashboard now shows the routes across all of your connectors — Cloudflare Mesh and Cloudflare Tunnel routes alongside Cloudflare WAN and Magic Transit static routes — in a single table, instead of a separate routes view per product.

From the unified Routes page you can:

Visualize your network with an interactive map that shows how your destinations flow through to your connectors — including equal-cost multi-path (ECMP) routes where the same prefix is served by several connectors. Select a node to filter the table down to the routes behind it.
See every route in one table, with its destination, type, connector, priority, and source, and filter or sort to find what you need.
Create, edit, and delete routes of any supported type without leaving the page. When adding a Cloudflare WAN or Magic Transit static route, you now pick the next hop by connector name instead of typing its IP.
Manage virtual networks from a dedicated tab.
Test a route to see which connector and next hop a destination resolves to before you commit a change.

To find it, go to Networking > Routes in the dashboard sidebar.

Go to Routes ↗

Your existing routes, APIs, and configurations are unchanged — this is a dashboard experience that brings them together in one place. Learn how to add routes and manage virtual networks.

Durable Objects, Workers - New Asia-Pacific location hints: apac-ne and apac-se

Fri, 19 Jun 2026 00:00:00 GMT

Durable Objects now supports two new location hints for Asia-Pacific: apac-ne (Northeast Asia-Pacific) and apac-se (Southeast Asia-Pacific). Use apac-ne or apac-se when you want finer-grained placement within Asia-Pacific rather than the broader apac hint.

Use the new hints the same way as any other locationHint:

// Northeast Asia-Pacific (Japan, Korea, etc.)
const stubNE = env.MY_DURABLE_OBJECT.get(id, { locationHint: "apac-ne" });

// Southeast Asia-Pacific (Singapore, Indonesia, etc.)
const stubSE = env.MY_DURABLE_OBJECT.get(id, { locationHint: "apac-se" });

If your users are spread across all of Asia-Pacific, the existing apac hint remains the right choice. Only reach for apac-ne or apac-se when your traffic is clearly concentrated in one sub-region and you want to minimize round-trip time to that audience. The default behavior and what we generally recommended is not adding a location hint unless absolutely needed, this will create the Durable Object as close to the initializing request as possible to reduce latency.

As with all location hints, these are best-effort suggestions. Cloudflare will place the Durable Object in a nearby data center, not necessarily the exact hinted location.

For the full list of supported hints, refer to Data location — Provide a location hint.

Durable Objects - Outbound connections keep Durable Objects alive

Fri, 19 Jun 2026 00:00:00 GMT

Durable Objects now remain alive for the duration of active outbound connections created via connect() or an outbound WebSocket. Previously, a Durable Object would be evicted after 70-140 seconds of no incoming traffic, even if the object had an open outbound connection, which is a common pattern when streaming responses from a large language model (LLM) over TCP or an outbound WebSocket.

With this change, each active outbound connection prevents eviction. Once all outbound connections close, the standard 70-140 second inactivity window applies before the Durable Object is evicted.

Before: streaming connections were cut off by eviction

After: active outbound connections keep the Durable Object alive

If you are building agents on Cloudflare, this is especially relevant. An agent that streams tokens from an LLM while calling models, or that performs long-running tasks over an outbound connection, now stays alive for the duration of that connection instead of being evicted mid-stream.

Limits:

Each outbound connection keeps the Durable Object alive for a maximum of 15 minutes. After 15 minutes, the connection stops preventing eviction (the connection itself continues operating), and the standard eviction rules resume.
The Durable Object's existing per-account instance limits still apply.

For more information, refer to Lifecycle of a Durable Object.

Workers - Temporary accounts for AI agent deployments

Fri, 19 Jun 2026 00:00:00 GMT

AI agents can now deploy Workers to Cloudflare without first requiring a user to sign up, open a browser-based OAuth flow, click through the dashboard, or create an API token. When an agent tries to deploy without Cloudflare credentials, Wrangler can tell it to rerun with --temporary, then deploy the Worker to a temporary preview account.

To try this with your agent, update to Wrangler 4.102.0 or later, make sure you are logged out (wrangler logout), and then ask your agent to build something and deploy it to Cloudflare. The agent should follow Wrangler's output and deploy using the --temporary flag.

wrangler deploy --temporary

The temporary deployment stays live for 60 minutes. During that window, the agent can verify the Worker, redeploy changes, and return both the live Worker URL and claim URL. Opening the claim URL lets you sign in to or create a Cloudflare account and make the temporary account permanent.

Temporary preview accounts currently support a limited set of products, including Workers, Workers Static Assets, Workers KV, D1, Durable Objects, Hyperdrive, Queues, and SSL/TLS certificates. For supported products, limits, and claim behavior, refer to Claim deployments (temporary accounts).

For more context, refer to Temporary Cloudflare Accounts for Agents ↗.

Cloudflare One, Access - Cloudflare identity provider is now the default for new accounts

Thu, 18 Jun 2026 00:00:00 GMT

When you create a new Zero Trust organization, Cloudflare now adds the Cloudflare identity provider as your default login method. Previously, new organizations started with one-time PIN (OTP).

With the Cloudflare identity provider, your users authenticate using their existing Cloudflare account credentials, and authentication is restricted to members of your account. You can still add OTP or connect any third-party identity provider whenever you need to.

This change only applies to newly created accounts. Existing organizations keep the login methods they already have configured. If you would like to use the Cloudflare Identity Provider in an existing account, you must enable it.

Containers - exec() is now available for Containers

Thu, 18 Jun 2026 00:00:00 GMT

exec() is now available for Containers. Use this.ctx.container.exec() to start processes inside a running Container, stream standard input and output, inspect exit codes, and signal each process.

Call exec() from a class extending Container, or from another Durable Object through this.ctx.container. The associated Container must already be running.

This example starts the Container when needed, then reads its Node.js version:

src/index.jsjs

import { Container } from "@cloudflare/containers";

export class MyContainer extends Container {
	async readVersion() {
		if (!this.ctx.container.running) {
			await this.start();
		}

		const process = await this.ctx.container.exec(["node", "--version"]);
		const output = await process.output();
		const decoder = new TextDecoder();

		return {
			exitCode: output.exitCode,
			stdout: decoder.decode(output.stdout),
			stderr: decoder.decode(output.stderr),
		};
	}
}

src/index.tsts

import { Container } from "@cloudflare/containers";

export class MyContainer extends Container {
	async readVersion() {
		if (!this.ctx.container.running) {
			await this.start();
		}

		const process = await this.ctx.container.exec(["node", "--version"]);
		const output = await process.output();
		const decoder = new TextDecoder();

		return {
			exitCode: output.exitCode,
			stdout: decoder.decode(output.stdout),
			stderr: decoder.decode(output.stderr),
		};
	}
}

The command array starts an executable directly, without an implicit shell. Invoke a shell explicitly for pipes, redirects, or variable expansion.

One RPC method can coordinate multiple exec() calls in one caller-to-Durable Object round trip. It can also pass byte-oriented ReadableStream input or return streamed output with flow control.

For options and streaming examples, refer to Execute commands.

Hyperdrive, Workers - Create PlanetScale Postgres and MySQL databases, billed to your Cloudflare account

Thu, 18 Jun 2026 00:00:00 GMT

You can create PlanetScale Postgres and MySQL databases from Cloudflare and bill PlanetScale database usage through your Cloudflare account as a pay-as-you-go customer. Cloudflare contract customers will be able to add PlanetScale usage to their contract in July so reach out to your Cloudflare account team if interested.

Create a PlanetScale database from the Cloudflare dashboard to check out globally distributed Workers optimized for regional data access.

Go to Create a PlanetScale database ↗

PlanetScale databases created from Cloudflare work with Workers through Hyperdrive. Hyperdrive manages database connection pools and query caching, so you can use PlanetScale as a centralized relational database for Workers applications without changing your database drivers, object-relational mapping (ORM) libraries, or SQL tooling.

PlanetScale usage appears on your Cloudflare invoice each billing period as a dollar total at PlanetScale's standard pricing ↗. You can introspect per-database billing usage via PlanetScale's dashboard ↗.

When you create a PlanetScale database from the Cloudflare dashboard, you receive the same PlanetScale developer experience, including development branches, query insights, and Model Context Protocol (MCP) server support for agents.

To get started, refer to PlanetScale Postgres and MySQL with Hyperdrive.

Radar - Updated Workers AI popularity metric in Cloudflare Radar

Thu, 18 Jun 2026 00:00:00 GMT

Radar has changed how it measures Workers AI model and task popularity.

Previously, popularity was based on the number of unique accounts running inferences against each model or task. It is now based on the number of inferences, giving a more representative view of actual usage volume. This change will affect all new measurements as well as historical data. As a result, the model and task distributions shown on Radar may differ from what you saw previously, and historical trends may shift accordingly.

The Workers AI model popularity ↗ chart shows the distribution of inferences across models.

The Workers AI task popularity ↗ chart shows the distribution of inferences across tasks.

The same data is available via the following API endpoints:

Explore the data on the AI Insights page ↗.

Speed - Cloudflare Fonts error handling and security improvements

Thu, 18 Jun 2026 00:00:00 GMT

Cloudflare Fonts now forwards /cf-fonts requests to your origin server when it encounters invalid paths or unexpected runtime errors, instead of returning 4xx or 5xx responses directly. This update also adds additional input validation to enhance security.

Artifacts - Manage Artifacts from the Cloudflare dashboard

Wed, 17 Jun 2026 12:00:00 GMT

You can now configure Artifacts namespaces, repos, and tokens directly from the Cloudflare dashboard.

Artifacts is Git-compatible storage that lets you store repos on Cloudflare and interact with them using standard Git workflows.

You can view and create namespaces, which are top-level containers for repos:

You can view, create, fork, and search repos within a namespace:

You can open a repo to view its files and copy its Git remote URL.

You can also provision tokens directly from the dashboard to scope Git access to a single repo, with read tokens for clone, fetch, and pull workflows, or write tokens when a client needs to push changes.

To get started, go to the Cloudflare dashboard ↗ and select Storage & databases > Artifacts.

If you are enrolled in the Artifacts beta, you can use the dashboard to set up Artifacts. If you would like to join the beta, complete the request form ↗.

SSL/TLS - Post-quantum ML-DSA certificates for Authenticated Origin Pulls and Custom Origin Trust Store

Wed, 17 Jun 2026 00:00:00 GMT

Cloudflare now accepts ML-DSA ↗ (FIPS 204) post-quantum certificates on the connection between Cloudflare's edge and your origin server. Combined with our existing X25519MLKEM768 key agreement, this lets you establish end-to-end post-quantum authentication on the Cloudflare-to-origin connection.

ML-DSA is supported in two origin-facing features:

Authenticated Origin Pulls (AOP) — upload an ML-DSA client certificate that Cloudflare will present during the mTLS handshake to your origin. Available at both zone-level and per-hostname scopes.
Custom Origin Trust Store (COTS) — upload an ML-DSA certificate authority that Cloudflare will trust when validating your origin server certificate under Full (strict) encryption mode.

Agents, Workers - Agents SDK improves browser automation, code execution, and recovery

Tue, 16 Jun 2026 00:00:00 GMT

The latest release of the Agents SDK ↗ makes it easier to build agents that can safely interact with real systems and keep working through interruptions.

Agents can now browse websites through Browser Run, write code against external tools through Code Mode, use client-provided tools when delegating to Think sub-agents, and recover more reliably from deploys, Durable Object evictions, and connection churn.

Safer browser automation

Agents can now use Browser Run through a single durable browser_execute tool. Instead of choosing from a fixed list of actions, the model writes code against the Chrome DevTools Protocol (CDP) and can inspect pages, capture screenshots, read rendered content, debug frontend behavior, and interact with live browser sessions.

const browserTools = createBrowserTools({
	ctx: this.ctx,
	browser: this.env.BROWSER,
	loader: this.env.LOADER,
	session: { mode: "dynamic" },
});

const browserTools = createBrowserTools({
	ctx: this.ctx,
	browser: this.env.BROWSER,
	loader: this.env.LOADER,
	session: { mode: "dynamic" },
});

Browser sessions can be one-time, reused, or promoted from one-time to persistent during a run. This is useful when an agent needs a human to log in, complete MFA, or approve a sensitive action. The run can pause, keep the same tabs and cookies, and resume after approval.

The browser tools also add Live View URLs, optional session recording, and quick actions such as browser_markdown, browser_extract, browser_links, and browser_scrape for one-shot browsing tasks.

Resumable code execution with approvals

Code Mode now uses createCodemodeRuntime, connectors, and a durable execution log. This lets you give a model one codemode tool instead of a large prompt full of tool definitions. The model can discover the capabilities it needs, write code against typed globals, and reuse saved snippets.

const runtime = createCodemodeRuntime({
	ctx: this.ctx,
	executor: new DynamicWorkerExecutor({ loader: this.env.LOADER }),
	connectors: [new GithubConnector(this.ctx, this.env, connection)],
});

const result = streamText({
	model,
	messages,
	tools: { codemode: runtime.tool() },
});

const runtime = createCodemodeRuntime({
	ctx: this.ctx,
	executor: new DynamicWorkerExecutor({ loader: this.env.LOADER }),
	connectors: [new GithubConnector(this.ctx, this.env, connection)],
});

const result = streamText({
	model,
	messages,
	tools: { codemode: runtime.tool() },
});

When the code reaches an approval-gated action, the runtime pauses execution and returns a pending approval. After approval, completed calls replay from the durable log, the approved action runs, and the same code continues. This makes it practical to build agents that create issues, update external systems, or perform other side effects without custom pause-and-resume logic for every tool.

Better Think delegation

Think sub-agents can now use client-defined tools over the RPC chat() path. A parent agent can pass tool schemas with clientTools and resolve tool calls through onClientToolCall. This lets delegated agents use caller-provided capabilities without requiring a browser WebSocket.

await child.chat(message, callback, {
	signal,
	clientTools: [
		{
			name: "get_user_timezone",
			description: "Get the caller's timezone",
			parameters: { type: "object" },
		},
	],
	onClientToolCall: async ({ toolName, input }) => {
		return runClientTool(toolName, input);
	},
});

await child.chat(message, callback, {
	signal,
	clientTools: [
		{
			name: "get_user_timezone",
			description: "Get the caller's timezone",
			parameters: { type: "object" },
		},
	],
	onClientToolCall: async ({ toolName, input }) => {
		return runClientTool(toolName, input);
	},
});

Think Workflows also improve step.prompt(). A prompt step now runs a full agentic turn before returning structured output, so the agent can call tools before producing the typed result. This makes Workflow steps more useful for durable triage, research, and approval flows.

The unified Think execute tool can also include cdp.* browser capabilities alongside state.* and tools.* when Browser Run is bound.

Voice output device selection

Voice clients can route assistant audio to a specific output device. Use outputDeviceId with useVoiceAgent, or call client.setOutputDevice() from the framework-agnostic client.

const voice = useVoiceAgent({
	agent: "MyVoiceAgent",
	outputDeviceId: selectedSpeakerId,
});

const voice = useVoiceAgent({
	agent: "MyVoiceAgent",
	outputDeviceId: selectedSpeakerId,
});

Browsers without speaker-selection support continue playing through the default output device and report a non-fatal outputDeviceError.

Reliability fixes

This release includes several fixes for production agents:

useAgent and AgentClient handle WebSocket replacement more reliably during reconnects and configuration changes.
Chat stream replay is more reliable after reconnects, deploys, and provider errors.
Fiber recovery continues across multi-pass scans and backs off when recovery hooks keep failing.
Agent teardown continues even when the request that started teardown is canceled.
Large session histories use byte-budgeted reads to reduce memory pressure during startup.

AI Crawl Control - Pay Per Crawl advanced configuration

Tue, 16 Jun 2026 00:00:00 GMT

You can now configure advanced Pay Per Crawl settings for your zone, including:

Disable Pay Per Crawl by URI pattern using Configuration Rules to offer free access to specific pages while charging for others.
Dynamic pricing by having your origin return a crawler-price response header, or by using a Cloudflare Worker to set prices based on request properties.

When dynamic pricing is enabled, Pay Per Crawl adds a cf-pay-per-crawl request header to origin requests so your origin or Worker can determine the appropriate price.

Refer to the Advanced configuration documentation for details.

Cloudflare Images - New optimization features in Images

Tue, 16 Jun 2026 00:00:00 GMT

Workers VPC - TCP connections via connect() over VPC Networks

Tue, 16 Jun 2026 00:00:00 GMT

VPC Network bindings now support the connect() Socket API for raw TCP connections to private destinations, in addition to HTTP traffic via fetch().

This means Workers can now open TCP sockets to any private service reachable through the bound Cloudflare Tunnel, Cloudflare Mesh, or Cloudflare WAN on-ramp — Redis, Memcached, MQTT, custom binary protocols, or any other TCP-based service.

{
  "$schema": "./node_modules/wrangler/config-schema.json",
  "vpc_networks": [
    {
      "binding": "PRIVATE_NETWORK",
      "network_id": "cf1:network",
      "remote": true
    }
  ]
}

[[vpc_networks]]
binding = "PRIVATE_NETWORK"
network_id = "cf1:network"
remote = true

At runtime, use connect() on the binding to open a TCP socket to a private destination:

export default {
	async fetch(request: Request, env: Env) {
		// Open a TCP connection to a private Redis instance
		const socket = await env.PRIVATE_NETWORK.connect("10.0.1.50:6379");

		// Write a Redis PING command
		const writer = socket.writable.getWriter();
		await writer.write(new TextEncoder().encode("PING\r\n"));
		await writer.close();

		return new Response(socket.readable);
	},
};

For more details, refer to VPC Networks and the Workers Binding API.

Workers - Workers tracing now supports custom spans

Tue, 16 Jun 2026 00:00:00 GMT

You can now create custom trace spans in your Workers code using tracing.enterSpan(). Custom spans appear alongside the automatic platform instrumentation (fetch calls, KV reads, D1 queries, and other platform operations) in your traces and OpenTelemetry exports, with correct parent-child nesting.

The API is available via import { tracing } from "cloudflare:workers" or through the handler context as ctx.tracing:

import { tracing } from "cloudflare:workers";

export default {
  async fetch(request, env, ctx) {
    return tracing.enterSpan("handleRequest", async (span) => {
      span.setAttribute("url.path", new URL(request.url).pathname);
      const data = await env.MY_KV.get("key");
      return new Response(data);
    });
  },
};

Spans nest automatically based on the JavaScript async context, and are auto-ended when the callback returns or its returned promise settles. The Span object provides setAttribute(key, value) for attaching metadata and an isTraced property to check whether the current request is being sampled.

Tracing must be enabled in your Wrangler configuration for spans to be recorded.

For full API details and examples, refer to Custom spans.

WAF - Use Cloudforce One threat intelligence in WAF rules

Mon, 15 Jun 2026 00:00:00 GMT

You can now match incoming requests against Cloudforce One threat intelligence in your WAF rules. A new detection looks up the client IP address of each request against the threat intelligence database. If the IP was involved in threat activity in the past seven days, Cloudflare populates cf.intel.ip.* fields that you can use in custom rules and rate limiting rules.

The detection populates the following fields. Use the any() function with the [*] wildcard to match array values:

cf.intel.ip.datasets — the dataset that flagged the IP address (ddos or waf).
cf.intel.ip.target_industries — industries the IP address has targeted.
cf.intel.ip.attacker_names — known threat actors associated with the IP address.
cf.intel.ip.attacker_countries — source countries of the threat activity.
cf.intel.ip.target_countries — countries the IP address has targeted.

For example, the following custom rule expression blocks requests from IP addresses associated with DDoS activity that have targeted France:

any(cf.intel.ip.target_countries[*] == "FR") and any(cf.intel.ip.datasets[*] == "ddos")

These fields work with the Cloudflare API and Terraform. Matches are logged in Security Analytics.

The threat intelligence detection is available to customers with an active Cloudforce One subscription. For more information, refer to Threat intelligence.

WAF - WAF Release - 2026-06-15

Mon, 15 Jun 2026 00:00:00 GMT

This week's release introduces new managed protection to address a critical SQL injection vulnerability in Ghost CMS (CVE-2026-26980) and a new generic rule designed to identify and block sophisticated SQL Injection (SQLi) bypass attempts leveraging obfuscated boolean logic. These rules protect affected installations from unauthorized data exfiltration at the network edge.

Key Findings

CVE-2026-26980: A blind SQL injection vulnerability in the Ghost CMS Content API (versions 3.24.0 to 6.19.0) allows unauthenticated remote attackers to inject malicious SQL commands via query parameters due to improper input validation.

Ruleset	Rule ID	Legacy Rule ID	Description	Previous Action	New Action	Comments
Cloudflare Managed Ruleset		N/A	Ghost CMS - SQLi - CVE:CVE-2026-26980	Log	Block	This is a new detection.
Cloudflare Managed Ruleset		N/A	SQLi - Obfuscated Boolean - URI	Log	Disabled	This is a new detection.

AI Gateway - View the user agent of requests in AI Gateway logs

Fri, 12 Jun 2026 00:00:00 GMT

AI Gateway logs now capture the user agent of the client that made each request, making it easier to identify which SDK, library, or application sent the traffic flowing through your gateway. For example, you can tell apart requests coming from openai-python versus a custom application or a Cloudflare Worker.

The user agent appears alongside the other details in each log entry, and you can filter logs by user agent (equals, does not equal, or contains) in the dashboard.

For more information, refer to Logging.

Durable Objects, Workers - Filter Durable Objects metrics by object ID or name

Fri, 12 Jun 2026 00:00:00 GMT

You can now filter the Metrics tab for a Durable Objects namespace by an individual Durable Object's ID or name in the Cloudflare dashboard. Previously, metrics charts only showed aggregate, namespace-level data, making it difficult to isolate the behavior of a specific object.

Go to Durable Objects ↗

Start typing an ID or name into the filter and select a match from the autocomplete dropdown. The autocomplete only shows objects with invocations during the selected time range, so an object that does not appear has not been invoked in that window. This does not necessarily mean the object has been deleted. Every chart on the page updates to reflect only the selected object. This makes it easier to identify and investigate a single Durable Object when debugging a high-traffic object, an error spike, or unexpected storage usage. Clear the filter to return to namespace-level metrics.

Metrics are powered by the GraphQL Analytics API, so standard analytics behavior such as ingestion delay and sampling applies.

For more information, refer to Metrics and analytics.

Terraform - Terraform v5.20.0 now available

Fri, 12 Jun 2026 00:00:00 GMT

Workers AI - Moonshot AI Kimi K2.7 Code now available on Workers AI

Fri, 12 Jun 2026 00:00:00 GMT

@cf/moonshotai/kimi-k2.7-code is now available on Workers AI. Kimi K2.7 Code is a code-optimized variant of the Kimi K2 family, built on a Mixture-of-Experts architecture with 1T total parameters and 32B active per token.

Improved coding and agent performance

K2.7 Code delivers meaningful gains over K2.6 on coding and agentic benchmarks:

+21.8% on Kimi Code Bench v2
+11.0% on Program Bench
+31.5% on MLS Bench Lite

Reasoning efficiency

K2.7 Code uses 30% fewer reasoning tokens compared to K2.6, reducing overthinking and lowering inference cost for reasoning-heavy workloads.

Key capabilities

262.1k token context window for retaining full conversation history, tool definitions, and codebases across long-running agent sessions
Long-horizon coding with improved instruction following and higher end-to-end coding task success rates
Vision inputs for processing images alongside text
Thinking mode with configurable reasoning depth via chat_template_kwargs.thinking
Multi-turn tool calling for building agents that invoke tools across multiple conversation turns
Structured outputs with JSON schema support

Differences from Kimi K2.6

If you are migrating from Kimi K2.6, note the following:

K2.7 Code is optimized for coding tasks with improved benchmark performance and reasoning efficiency
Cached input token pricing is $0.19 per M tokens (vs $0.16 for K2.6)
API usage is identical — no parameter changes required

Get started

Use Kimi K2.7 Code through the Workers AI binding (env.AI.run()), the REST API at /ai/run, or the OpenAI-compatible endpoint at /v1/chat/completions. You can also use AI Gateway with any of these endpoints.

For more information, refer to the Kimi K2.7 Code model page and pricing.

Browser Run - New formats parameter for the Browser Run /snapshot endpoint

Thu, 11 Jun 2026 00:00:00 GMT

Browser Run's /snapshot endpoint now supports a formats parameter that lets you return multiple page formats in a single API call. Previously, /snapshot returned only HTML content and a screenshot. You can now also include Markdown and the accessibility tree in the same response.

These formats are particularly useful for AI agent workflows:

Markdown provides a token-efficient representation of page content that LLMs can process directly, without parsing HTML markup.
The accessibility tree provides a structured representation of a page's elements, including roles, labels, and hierarchy, helping LLMs understand page structure and navigate its contents.

The following example returns a screenshot, Markdown, and the accessibility tree in one call:

curl -X POST 'https://api.cloudflare.com/client/v4/accounts/<accountId>/browser-rendering/snapshot' \
  -H 'Authorization: Bearer <apiToken>' \
  -H 'Content-Type: application/json' \
  -d '{
    "url": "https://example.com/",
    "formats": ["screenshot", "markdown", "accessibilityTree"]
  }'

import Cloudflare from "cloudflare";

const client = new Cloudflare({
	apiToken: process.env["CLOUDFLARE_API_TOKEN"],
});

const snapshot = await client.browserRendering.snapshot.create({
	account_id: process.env["CLOUDFLARE_ACCOUNT_ID"],
	url: "https://example.com/",
	formats: ["screenshot", "markdown", "accessibilityTree"],
});

console.log(snapshot.markdown);
console.log(snapshot.accessibilityTree);

interface Env {
	BROWSER: BrowserRun;
}

export default {
	async fetch(request, env): Promise<Response> {
		return await env.BROWSER.quickAction("snapshot", {
			url: "https://example.com/",
			formats: ["screenshot", "markdown", "accessibilityTree"],
		});
	},
} satisfies ExportedHandler<Env>;

You must request at least two formats. If you only need one, use the respective single-format endpoint such as /screenshot or /markdown.

Refer to the /snapshot documentation for the full list of accepted values.

Data Loss Prevention - Define custom topics for AI prompt protection

Thu, 11 Jun 2026 00:00:00 GMT

You can now define custom topics for AI prompt protection. Predefined AI prompt topics cover common content and intent categories such as PII, source code, and jailbreak attempts. Custom topics let you detect unique or proprietary concepts that are not included in predefined categories.

You describe a custom topic in natural language, and Cloudflare DLP detects whether a prompt matches that topic based on context rather than specific keywords. For example, a topic that describes confidential merger discussions matches a prompt that paraphrases the deal, even when the prompt never uses the word merger or names the companies involved. To detect literal values such as internal codenames or product identifiers, use a custom wordlist or pattern entry instead.

Custom topics run through the same application granular controls path as predefined AI prompt topics. Custom topics are available for ChatGPT, Google Gemini, Perplexity, and Claude.

Create a custom AI prompt topic

In the Cloudflare dashboard ↗, go to Zero Trust > Data loss prevention > Detection entries.
Select AI prompt topics, then select Custom Prompt Topic.
Describe the topic in natural language. Be specific about the concept you want to detect. For example, describe unreleased product roadmap details or confidential customer contract terms.
Add this detection entry to an existing DLP profile, or create a new DLP profile.
Use the profile in a Gateway HTTP policy to log or block prompts that match the topic.

For more information, refer to AI prompt topics.

Workers - Track Dynamic Workers usage from the dashboard and GraphQL API

Thu, 11 Jun 2026 00:00:00 GMT

Customers can now view the number of Dynamic Workers invoked during their billing period from the Workers overview page in the Cloudflare dashboard.

This count reflects the number of Dynamic Workers that Cloudflare would bill for during the selected billing period. Dynamic Workers usage data only goes back to June 1, 2026.

You can also query this count through the GraphQL Analytics API by using workersInvocationsByOwnerAndScriptGroups and selecting distinctDynamicWorkerCount:

query getDynamicWorkersCount(
	$accountTag: string!
	$filter: AccountWorkersInvocationsByOwnerAndScriptGroupsFilter_InputObject
) {
	viewer {
		accounts(filter: { accountTag: $accountTag }) {
			workersInvocationsByOwnerAndScriptGroups(limit: 10000, filter: $filter) {
				uniq {
					distinctDynamicWorkerCount
				}
			}
		}
	}
}

Use variables to set the account and billing-period date range:

{
	"accountTag": "<ACCOUNT_ID>",
	"filter": {
		"date_geq": "2026-06-01",
		"date_leq": "2026-06-30"
	}
}

For more information, refer to Dynamic Workers pricing.

AI Search - Manage AI Search namespaces with Wrangler CLI

Wed, 10 Jun 2026 00:00:00 GMT

AI Search now supports namespace-level Wrangler commands, making it easier to manage namespaces from your terminal, scripts, and agent workflows.

The following commands are available:

Command	Description
`wrangler ai-search namespace list`	List AI Search namespaces
`wrangler ai-search namespace create`	Create a new AI Search namespace
`wrangler ai-search namespace get`	Get details for a namespace
`wrangler ai-search namespace update`	Update a namespace description
`wrangler ai-search namespace delete`	Delete an AI Search namespace

Create a namespace for a new application or tenant directly from the CLI:

wrangler ai-search namespace create docs-production --description "Production documentation search"

List namespaces with pagination or filter by name or description:

wrangler ai-search namespace list --search docs --page 1 --per-page 10

Use --json with list, create, get, and update to return structured output that automation and AI agents can parse directly.

Instance-level commands also now support a --namespace flag, so you can interact with instances inside a specific namespace from the CLI:

wrangler ai-search list --namespace docs-production

For full usage details, refer to the AI Search Wrangler commands documentation.

DNS - Account-level DNS records quota

Wed, 10 Jun 2026 00:00:00 GMT

Cloudflare now enforces DNS records quotas at the account level for Enterprise accounts. Instead of a per-zone limit, these accounts have a quota on the total number of records across all of their zones, letting you distribute records across your zones however you like — regardless of each zone's plan. Public and internal zones are counted separately, each with a default quota of 1,000,000 records.

Accounts without an account-level quota are unaffected: existing per-zone quotas behave exactly as before.

For more details, refer to DNS records quota.

Flagship - Flagship API reference now available

Wed, 10 Jun 2026 00:00:00 GMT

The Flagship API reference is now available. You can use the Cloudflare API to create and update apps, and to create, update, delete, and list feature flags without using the dashboard.

For example, create a new boolean flag with the API:

curl https://api.cloudflare.com/client/v4/accounts/$ACCOUNT_ID/flagship/apps/$APP_ID/flags \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer $CLOUDFLARE_API_TOKEN" \
  -d '{
    "key": "new-checkout",
    "enabled": true,
    "default_variation": "off",
    "variations": {
      "off": false,
      "on": true
    },
    "rules": []
  }'

To create an API token, go to Account API Tokens ↗ in the Cloudflare dashboard and search for Flagship.

The API reference includes endpoints for Flagship apps, flags, changelog entries, and flag evaluation. Agents can also use the Flagship reference in the Cloudflare skill ↗ to create and manage Flagship resources.

Refer to the Flagship documentation to learn more about evaluating feature flags from your applications.

Cloudflare Images - Manage hosted images with the Images binding

Wed, 10 Jun 2026 00:00:00 GMT

Use the Images binding to upload, list, retrieve, update, and delete images stored in Images directly from your Worker without managing API tokens or making HTTP requests.

The env.IMAGES.hosted namespace supports the following storage and management operations:

.upload(image, options) — Upload a new image to your account.
.list(options) — List images with pagination.
.image(imageId).details() — Get image metadata.
.image(imageId).bytes() — Stream the original image bytes.
.image(imageId).update(options) — Update metadata or access controls.
.image(imageId).delete() — Delete an image.

For example, you can upload an image from a request body and return its metadata:

const image = await env.IMAGES.hosted.upload(request.body, {
	filename: "upload.jpg",
	metadata: { source: "worker" },
});

return Response.json(image);

Or retrieve and serve the original bytes of a hosted image:

const bytes = await env.IMAGES.hosted.image("IMAGE_ID").bytes();
return new Response(bytes);

For more information, refer to the Images binding.

Security Center - Automated Cease and Desist templates for Brand Protection

Wed, 10 Jun 2026 00:00:00 GMT

TL;DR: Brand Protection now features an Automated Cease & Desist (C&D) workflow. When you discover an infringing domain hosted outside of Cloudflare, you can instantly generate, review, and download a custom-branded, pre-filled legal notice in seconds.

Why this matters

This update introduces a major shift from pure detection to actionable enforcement, eliminating the manual burden for your Trust & Safety and Legal teams:

Instant WHOIS and Recipient Lookup: We automatically scrape registrar data and WHOIS contact information (such as the registrant or registrar abuse email) behind the scenes, highlighting exactly where your notice needs to be sent
Smart Template Automation: We pre-fill your custom-branded templates with essential metadata, including the infringing domain, registrar name, and discovery date.
Tailored Enforcement Tones: Choose from three default layout strategies depending on the severity of the infrastructure match:
- Exact Match: A formal demand for identical trademark infringements
- Similar Match: A standard notice optimized for typosquatting (one-character distance matches)
- Friendly Tone: An amicable initial outreach for potential unintentional or accidental infringements
Full Editing Control: Before creating the final PDF, a real-time review screen allows you to fine-tune the messaging, modify placeholders, and ensure your text aligns perfectly with internal legal standards

How it works

When reviewing a malicious domain match inside your dashboard, your enforcement path splits depending on where the attacker is located:

On the Cloudflare Network: If the domain uses Cloudflare’s network or registrar, trigger our existing integrated abuse reporting flow with one click.
Hosted Elsewhere: If the domain is hosted on an external provider, click the Generate C&D Letter option to launch the new document builder, pick your template, verify the auto-populated recipient data, and download your finalized PDF.

You can manage your templates and enforce matches by going to the Cloudflare Dashboard > Application Security > Brand Protection and selecting your detected Brand Protection matches. For more information, read the Brand Protection documentation.

Note: Cloudflare does not represent you and cannot provide you with legal advice. Only you can decide whether your rights have been infringed, whether a cease and desist letter is appropriate, and what that letter should say.

Sandbox SDK - Deprecating Sandbox SDK features

Tue, 09 Jun 2026 00:00:00 GMT

Today we are announcing the deprecation of several features from the Sandbox SDK. The SDK has grown and matured substantially since it first launched. As agent workflows have developed, we have shipped many new features and experiments so developers can easily integrate secure, isolated code execution into their workflows.

We want the SDK to continue providing a stable foundation for agentic workflows while we iterate quickly on the codebase. These deprecated features have either been superseded by newer capabilities or seen low adoption. Do not build new work on them. Migrate using the 2026 deprecation migration guide, or move to the Sandbox SDK 1.0 preview when you can.

HTTP and WebSocket transports

In April 2026, we released the new RPC transport and deprecated the WebSocket transport. This setting governs how the sandbox container talks to the Workers ecosystem. The RPC transport removes the limitations of both the HTTP and WebSocket transports. As of this announcement, RPC is the recommended default. HTTP and WebSocket transports are deprecated and will not ship in future Sandbox SDK majors.

To migrate, update the SANDBOX_TRANSPORT variable to rpc or set the transport option when calling getSandbox(). For more information, refer to the transport configuration documentation.

Desktop

The desktop feature ran a full Linux desktop inside the sandbox (display server, desktop environment, and VNC/noVNC) so agents and apps could drive a GUI with screenshots, mouse, and keyboard — the same computer-use shape other sandbox products expose for UI automation. Adoption stayed low, and we removed it in 0.10.2. If you need that capability again, you can build it on top of the sandbox with extensions rather than a built-in sandbox.desktop API.

Expose ports

We recently released support for Cloudflare Tunnel in the Sandbox SDK. This provides a robust API for exposing services running in your sandbox to the public internet. It fixes issues many were facing with local development and deployment to workers.dev domains. To migrate from exposePort() to tunnels, refer to the tunnels API documentation and the expose services guide.

Default sessions

By default, the exec() method in the Sandbox SDK maintains a default session across all calls, so a cd in one call is honored in the next. This convenience helped developers writing exec statements by hand, but confused agents and caused hard-to-trace bugs. As of 0.10.3, we have introduced the enableDefaultSession flag on the getSandbox() interface to turn this off. Default sessions as a concept — and the flag — will be removed in an upcoming release.

We recommend setting enableDefaultSession: false today and using the sandbox.createSession() API when you need the previous behavior.

Other changes

We are also consolidating all APIs that buffer data to support streaming by default. This includes readFile, writeFile, and exec. The stream equivalents will be removed.

We are exploring moving non-core features like the code interpreter, terminal, and git APIs into helpers. These features will retain their existing APIs, so migration should be simple.

Next steps

If you use any of these features on the current stable package, refer to the 2026 deprecation migration guide. Coding agents can use the sandbox-stable skill for stable-package work and that guide for cleanup (Agent setup · Cloudflare Skills ↗).

If you are moving to Sandbox SDK 1.0 (@next), use the 1.0 preview and Migrate guides instead — or the sandbox-migrate-to-next skill after installing Cloudflare Skills. New projects should prefer sandbox-next on @next.

For any questions, ask in the Cloudflare Developers Discord ↗.

WAF - WAF Release - 2026-06-09

Tue, 09 Jun 2026 00:00:00 GMT

This release introduces new detections for a critical SQL injection vulnerability in Drupal installations utilizing PostgreSQL (CVE-2026-9082), alongside targeted protection for an unsafe deserialization flaw in the Mirasvit Cache Warmer extension (CVE-2026-45247). Additionally, this release includes coverage for a prototype pollution vector in Axios (CVE-2026-40175) and a new generic rule designed to identify and block sophisticated SQL Injection (SQLi) bypass attempts leveraging obfuscated boolean logic.

Key Findings

CVE-2026-9082: A database abstraction vulnerability affects Drupal sites configured with a PostgreSQL backend. Remote, unauthenticated attackers can exploit this flaw via crafted inputs to inject malicious SQL commands and access or manipulate backend data.
CVE-2026-45247: A PHP Object Injection vulnerability exists in the Mirasvit Cache Warmer extension for Magento and Adobe Commerce. This flaw stems from unsafe deserialization of untrusted user input, enabling unauthenticated attackers to execute arbitrary code on the hosting server.
CVE-2026-40175: A prototype pollution vulnerability affects the Axios HTTP client library. Attackers can exploit this to inject malicious properties into the global JavaScript object prototype, potentially causing application crashes (Denial of Service) or executing unauthorized code depending on the application structure.

Impact

Successful exploitation of these vulnerabilities could allow unauthenticated attackers to execute arbitrary code, manipulate database contents, or induce application crashes, leading to severe operational disruption or complete server compromise. These newly deployed signatures intercept these advanced malicious payloads at the edge before they can interact with vulnerable software configurations.

Ruleset	Legacy Rule ID	Description	Previous Action	New Action	Comments
Cloudflare Managed Ruleset	N/A	Axios - Prototype Pollution - CVE:CVE-2026-40175	Log	Block	This is a new detection.

Email Service - Authenticated SMTP submission now available in beta

Mon, 08 Jun 2026 00:00:00 GMT

You can now send emails through Cloudflare Email Service using authenticated SMTP submission on smtp.mx.cloudflare.net:465. SMTP joins the REST API and the Workers binding as a third way to send transactional email — useful for existing applications that already speak SMTP and language-native SMTP libraries (Nodemailer, smtplib, PHPMailer, JavaMail).

Setting	Value
Host	`smtp.mx.cloudflare.net`
Port	`465` (implicit TLS)
AUTH	`PLAIN` or `LOGIN`
Username	`api_token`
Password	A Cloudflare API token (account-owned or user-owned) with Email Sending: Edit

Submissions enter the same delivery pipeline as the REST API and Workers binding: identical limits, automatic DKIM and ARC signing, and shared dashboard logs.

Send your first email with a single command:

curl --ssl-reqd \
  --url "smtps://smtp.mx.cloudflare.net:465" \
  --user "api_token:<API_TOKEN>" \
  --mail-from "welcome@yourdomain.com" \
  --mail-rcpt "user@example.com" \
  --upload-file mail.txt

Refer to the SMTP reference for authentication details, response codes, and language-specific examples.

R2 SQL - R2 SQL now supports UNION, INTERSECT, EXCEPT, and SELECT DISTINCT

Mon, 08 Jun 2026 00:00:00 GMT

R2 SQL now supports set operations (UNION, INTERSECT, EXCEPT) and SELECT DISTINCT, expanding the range of analytical queries you can run directly on Apache Iceberg ↗ tables in R2 Data Catalog.

Set operations

Combine the results of multiple SELECT statements:

UNION — returns all rows from both queries, removing duplicates
UNION ALL — returns all rows from both queries, including duplicates
INTERSECT — returns only rows that appear in both queries
EXCEPT — returns rows from the first query that do not appear in the second

-- Find zones that had either firewall blocks OR high-risk requests
SELECT zone_id FROM my_namespace.firewall_events WHERE action = 'block'
UNION
SELECT zone_id FROM my_namespace.http_requests WHERE risk_score > 0.8

-- Find zones with both firewall blocks AND high traffic
SELECT zone_id FROM my_namespace.firewall_events WHERE action = 'block'
INTERSECT
SELECT zone_id FROM my_namespace.http_requests
GROUP BY zone_id
HAVING COUNT(*) > 10000

-- Find enterprise zones that have not been compacted
SELECT zone_id FROM my_namespace.zones WHERE plan = 'enterprise'
EXCEPT
SELECT zone_id FROM my_namespace.compaction_history

Select distinct

Eliminate duplicate rows from query results:

SELECT DISTINCT region, department
FROM my_namespace.sales_data
WHERE total_amount > 1000
ORDER BY region, department
LIMIT 100

For large datasets where approximate results are acceptable, approx_distinct() remains a faster alternative for counting unique values.

For the full syntax reference, refer to the SQL reference. For performance guidance, refer to Limitations and best practices.

Realtime - Post-meeting transcriptions are now Generally Available in RealtimeKit

Mon, 08 Jun 2026 00:00:00 GMT

RealtimeKit lets you build products where people meet over live audio and video — such as HealthTech, EdTech, proctoring, and other real-time platforms — on Cloudflare's global WebRTC infrastructure.

Post-meeting transcription is now Generally Available, so completed RealtimeKit meetings can automatically produce full transcript files after they end. Those transcripts can also power AI-generated summaries for meeting notes, review workflows, and follow-up tasks after the transcript is available.

Post-meeting transcription is a managed service powered by Workers AI using Whisper Large v3 Turbo. RealtimeKit handles transcription processing and can return transcript and summary files through webhooks or the REST API, so you do not need to run your own transcription infrastructure.

Generate transcripts and summaries

To generate a transcript after a meeting ends, set transcribe_on_end: true when creating a meeting. To also generate an AI summary automatically after the transcript is available, set summarize_on_end: true:

curl -X POST "https://api.cloudflare.com/client/v4/accounts/$ACCOUNT_ID/realtime/kit/$APP_ID/meetings" \
  -H "Authorization: Bearer $CLOUDFLARE_API_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
    "title": "Weekly product review",
    "transcribe_on_end": true,
    "summarize_on_end": true,
    "ai_config": {
      "transcription": {
        "language": "en"
      },
      "summarization": {
        "word_limit": 500,
        "text_format": "markdown",
        "summary_type": "team_meeting"
      }
    }
  }'

Consume results

When RealtimeKit finishes processing a meeting, it creates download URLs for the transcript and, if summarize_on_end is set, the summary. You can receive those URLs automatically with webhooks, or fetch them later for a specific session with the REST API.

To receive results as soon as they are ready, configure the meeting.transcript and meeting.summary webhook events:

curl -X POST "https://api.cloudflare.com/client/v4/accounts/$ACCOUNT_ID/realtime/kit/$APP_ID/webhooks" \
  -H "Authorization: Bearer $CLOUDFLARE_API_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
    "name": "AI results webhook",
    "url": "https://example.com/webhook",
    "events": ["meeting.transcript", "meeting.summary"],
    "enabled": true
  }'

To fetch results later, call the transcript or summary endpoint for the session:

curl -X GET "https://api.cloudflare.com/client/v4/accounts/$ACCOUNT_ID/realtime/kit/$APP_ID/sessions/$SESSION_ID/transcript" \
  -H "Authorization: Bearer $CLOUDFLARE_API_TOKEN"

curl -X GET "https://api.cloudflare.com/client/v4/accounts/$ACCOUNT_ID/realtime/kit/$APP_ID/sessions/$SESSION_ID/summary" \
  -H "Authorization: Bearer $CLOUDFLARE_API_TOKEN"

Use the Generate summary of transcripts for the session API only if summarize_on_end was not set and you want to generate a summary manually after the transcript is available:

curl -X POST "https://api.cloudflare.com/client/v4/accounts/$ACCOUNT_ID/realtime/kit/$APP_ID/sessions/$SESSION_ID/summary" \
  -H "Authorization: Bearer $CLOUDFLARE_API_TOKEN"

Post-meeting transcription supports CSV, JSON, SRT, and VTT transcript outputs, automatic language detection and Whisper language codes. RealtimeKit also supports real-time transcription with Deepgram Nova-3 for live captions, in-meeting accessibility, and real-time note-taking.

Learn more in the RealtimeKit transcription docs and summary docs.

Security Center - Create WAF rules directly from Threat Events saved views

Mon, 08 Jun 2026 00:00:00 GMT

Cloudforce One users can now turn Threat Events indicators into active defense. With this update, users can instantly generate a WAF rule that matches the dynamic list of IP addresses returned by any of their Saved Views.

Why this matters

Threat intelligence is most effective when it is immediately actionable. Previously, blocking threat actors required manually extracting indicators from threat events and copying them into your firewall rules. This new integration bridges the gap between threat discovery and threat mitigation:

When you identify an active threat pattern - such as an ongoing campaign targeting a specific industry, or using a known indicator type - you can pivot from investigation to mitigation in a single click.
Instead of writing complex, static IP rules, this functionality allows you to leverage the specific filtering logic you have already defined and saved within your Threat Events ecosystem.
Automating the generation of the WAF rule expression from your threat views eliminates manual copying errors, ensuring that the right malicious infrastructure is blocked instantly.

How to use it

You can implement these rules through both the dashboard UI and via the API / Terraform.

Go to Cloudflare Dashboard > Application Security > Threat Intelligence > Manage Views, select your desired view, and select Create WAF Rule.

This will automatically pre-populate the WAF rule builder with the matching threat event IP indicators.

You can also automate this workflow by utilizing the WAF Rule Builder API alongside your Threat Events saved views endpoints.

Security Center - Introducing Threat Actor Profiles in Threat Events

Mon, 08 Jun 2026 00:00:00 GMT

TL;DR: We’ve launched Threat Actor Profiles directly inside the Threat Events dashboard. You can now immediately pivot from a generic alert or blocked event to a profile that unmasks the "Who, Why, and How" behind a threat event.

Why this matters

Security teams often suffer from a visibility gap. When an attack is blocked, it's difficult to know if it was a random automated bot or a sophisticated advanced persistent threat (APT) campaign specifically targeting your industry. Finding out usually means leaving your security dashboard to hunt through external OSINT feeds or static, out-of-date threat reports. Threat Actor Profiles solve this by sharing Cloudforce One’s deep adversary research directly inside your workflow:

Cloudflare sees the traffic in real-time across approximately 20% of the web. This means actor profiles display active malicious infrastructure the moment it touches our global edge.
Every profile provides clear strategic and tactical modules including alternative aliases, origin tracking, historical threat event volume, and MITRE ATT&CK mapping detailing the adversary's technical methods.
You can search the dedicated threat actor directory or click an actor's name inside any threat event to view all details and related events to the specific threat actor.

How to use it

Adversary tracking is now available in the Cloudflare Dashbboard and ready to be included in your daily investigation workflow:

Click on the Threat Actor name in the Threat Events table to open their full identity profile and review their aliases and attack stats.
Navigate to Cloudflare Dashboard > Application Security > Threat Intelligence to explore the new Threat Actors tab. Here, you can browse a card-based directory of all established entities tracked by Cloudforce One.

Learn more in the Cloudforce One documentation ↗.

Workflows - Rollback support now available in Workflows

Fri, 05 Jun 2026 15:00:00 GMT

Workflows now supports saga-style rollbacks, allowing you to add compensating logic to each step.do() in case of downstream failures. If the instance fails, the rollback handlers will execute in reverse step-start order.

This is useful for multi-step operations that touch external systems, such as inventory reservations, payment authorization, ticket creation, or infrastructure provisioning. Instead of writing all cleanup logic in a top-level catch, you can keep each compensating action next to the step it undoes.

Rollback handlers support their own retry and timeout configuration, and Workflows now exposes rollback outcomes in instance status responses. Workflows analytics also emits rollback lifecycle events, making it easier to distinguish a forward execution failure from a rollback failure when debugging production workflows.

await step.do(
	"provision resource",
	async () => {
		const resource = await provisionResource();
		return { resourceId: resource.id };
	},
	{
		rollback: async ({ output }) => {
			const { resourceId } = output;
			await deleteResource(resourceId);
		},
		rollbackConfig: {
			retries: { limit: 3, delay: "15 seconds", backoff: "linear" },
			timeout: "2 minutes",
		},
	},
);

await step.do(
	"provision resource",
	async () => {
		const resource = await provisionResource();
		return { resourceId: resource.id };
	},
	{
		rollback: async ({ output }) => {
			const { resourceId } = output as { resourceId: string };
			await deleteResource(resourceId);
		},
		rollbackConfig: {
			retries: { limit: 3, delay: "15 seconds", backoff: "linear" },
			timeout: "2 minutes",
		},
	},
);

Refer to rollback options to learn more.

AI Gateway - Control AI costs with spend limits

Fri, 05 Jun 2026 00:00:00 GMT

AI Gateway now supports spend limits — cost-based budgets that track cumulative dollar spend and block requests when the budget is exceeded. Unlike rate limiting, which caps the number of requests, spend limits track actual cost based on token usage and model pricing.

You can scope limits by model, provider, or custom metadata dimensions. For example, give each user a $200/day budget, cap total gateway spend at $10,000/day, or limit a specific model to $50/day per user. Each rule uses a configurable time window with fixed or sliding enforcement.

Spend limits work with both Unified Billing and BYOK requests for models with known pricing.

For more details, refer to the Spend limits documentation.

Radar - Finer-grained chart granularity on Cloudflare Radar for longer time ranges

Fri, 05 Jun 2026 00:00:00 GMT

Radar now provides finer-grained traffic charts for longer time ranges. Previously, selecting a 1-3 month view on HTTP and NetFlows charts defaulted to weekly aggregation, which was too coarse to surface meaningful trends. Views longer than 3 months defaulted to monthly aggregation, returning as few as 7 data points for a 6-month range.

The new defaults are:

1-3 months: daily granularity (7x more data points)
Longer than 3 months (HTTP and NetFlows): weekly granularity (4x more data points)

For example, a 12-week traffic view previously showed weekly data:

The same view now shows daily data:

Similarly, a 1-year HTTP traffic view that previously showed just 12 monthly data points now provides 52 weekly data points.

Visit Cloudflare Radar ↗ to explore the new granular views.

Gateway, Cloudflare Mesh, Workers VPC - Filter Workers' public Internet traffic using Gateway policies

Fri, 05 Jun 2026 00:00:00 GMT

Workers using a VPC Network binding with network_id: "cf1:network" now egress to public Internet destinations through Cloudflare Gateway. This means your existing Zero Trust traffic policies — DNS, HTTP, Network, and egress — extend to traffic that originates from your Workers, the same way they do for WARP users today.

Worker
Calls env.EGRESS.fetch()
VPC binding
Cloudflare Mesh
Bind via cf1:network

Cloudflare Gateway
Policies applied:

Gateway logsDNSHTTPNetwork

What you get by default:

Visibility. Worker egress shows up in Gateway DNS, HTTP, and Network logs alongside your other traffic, so you can audit what your Workers are calling and when.
Enforcement. Any existing Gateway policy whose selectors match a Worker request will apply — including allow / block lists, DNS category filtering, and HTTP destination rules. If you have already blocked a category for your workforce, your Workers inherit that block.

{
	"vpc_networks": [
		{
			"binding": "EGRESS",
			"network_id": "cf1:network",
			"remote": true,
		},
	],
}

[[vpc_networks]]
binding = "EGRESS"
network_id = "cf1:network"
remote = true

// Egress to a public destination — subject to your Gateway policies and logged
const response = await env.EGRESS.fetch("https://api.example.com/data");

// Egress to a public destination — subject to your Gateway policies and logged
const response = await env.EGRESS.fetch("https://api.example.com/data");

For configuration options, refer to VPC Networks. For policy authoring, refer to Cloudflare Gateway traffic policies.

Access - Share identity providers across accounts with IdP federation

Thu, 04 Jun 2026 00:00:00 GMT

Cloudflare Access now supports IdP federation, which allows organizations to share a single identity provider across multiple Cloudflare accounts.

Instead of configuring the same IdP (for example, Okta or Entra ID) separately in every account, you configure it once in a source account and share it with the other accounts in your organization. Each recipient account gets a read-only IdP connection that routes authentication back to the source account through a bridge — a hidden application in the source account that brokers the cross-account login. End users sign in with their existing IdP credentials, and each account's Access policies evaluate the resulting identity just like any other IdP login.

Key capabilities:

One IdP, many accounts — Configure your IdP once and share it with all accounts in your organization.
Lifecycle management — As accounts join or leave your Cloudflare organization, their IdP connections are provisioned and removed automatically — no manual cleanup required.
Immutable recipient connections — IdP connections in recipient accounts cannot be accidentally modified or deleted.

To get started, refer to IdP federation.

Cloudflare Fundamentals, Workers, D1, R2, KV, Queues, Vectorize, Durable Objects, Containers - Billable usage and budget alerts now in product sidebars

Thu, 04 Jun 2026 00:00:00 GMT

Pay-as-you-go customers can now view billable usage and create budget alerts directly from the product overview pages for Workers & Pages, D1, R2, Workers KV, Queues, Vectorize, Durable Objects, and Containers. A new sidebar widget shows current-period spend and the billing cycle date range, alongside a button to create a budget alert.

The widget pulls from the same data as the Billable Usage dashboard and aligns to your billing cycle (or the current day on Free plans), so the numbers match your invoice. Enterprise contract accounts are not yet supported.

Selecting Create budget alert opens the budget alert flow inline so you can set a dollar threshold in the same place you are reviewing usage. Budget alerts apply to your total account-level spend across all products, not just the product page you create them from.

For more information, refer to the Usage-based billing documentation.

Pipelines, Workers - Pipeline binding configuration field renamed to stream

Thu, 04 Jun 2026 00:00:00 GMT

The pipeline field inside the pipelines binding configuration in your Wrangler configuration file has been renamed to stream. The old field is deprecated but still accepted.

Update your configuration to use stream to avoid the deprecation warning.

Before (deprecated):

{
  "$schema": "./node_modules/wrangler/config-schema.json",
  "pipelines": [
    {
      "binding": "MY_PIPELINE",
      "pipeline": "<STREAM_ID>"
    }
  ]
}

[[pipelines]]
binding = "MY_PIPELINE"
pipeline = "<STREAM_ID>"

After:

{
  "$schema": "./node_modules/wrangler/config-schema.json",
  "pipelines": [
    {
      "binding": "MY_PIPELINE",
      "stream": "<STREAM_ID>"
    }
  ]
}

[[pipelines]]
binding = "MY_PIPELINE"
stream = "<STREAM_ID>"

No other changes are required. The binding name, TypeScript types, and runtime API (env.MY_PIPELINE.send(...)) remain the same.

For more information on configuring pipeline bindings, refer to Writing to streams.

Access - SAML assertion encryption for identity providers

Wed, 03 Jun 2026 00:00:00 GMT

Cloudflare Access now supports SAML assertion encryption for identity provider integrations. When turned on, your identity provider encrypts SAML assertions using a Cloudflare-managed certificate before sending them through the user's browser. Only Access can decrypt these assertions, protecting sensitive identity data even after TLS termination.

Without encryption, SAML assertions are transmitted in plaintext and could be visible to browser extensions or client-side malware.

SAML encryption includes built-in certificate lifecycle management:

Automatic certificate generation: Access generates an encryption certificate when you turn on SAML encryption for an identity provider.
Certificate rotation: Rotate certificates without downtime. The previous certificate remains valid until expiration, giving you time to update your IdP.
PEM export: Copy the certificate in PEM format for manual upload to your IdP, or point your IdP to the SAML metadata endpoint for automatic retrieval.

To get started, refer to Encrypt SAML assertions.

Cloudflare Fundamentals - Introducing self-managed OAuth clients

Wed, 03 Jun 2026 00:00:00 GMT

Today we are launching self-managed OAuth, enabling developers to build third-party applications that integrate with Cloudflare via OAuth. This provides a more secure, user-friendly, and manageable alternative to API tokens.

OAuth lets third-party applications act on behalf of a user to access their Cloudflare account. For example, after a user grants consent, Wrangler can deploy Workers into that account.

What is new

Cloudflare Developers can now create and manage their own OAuth applications to integrate with Cloudflare.

Create an application

To create an application, go to Manage account > OAuth clients in your account on the Cloudflare dashboard.

Go to OAuth clients ↗

Select limited scopes

If you have used an API token to call Cloudflare APIs, OAuth client scopes will look familiar. Select only the scopes your application needs during application creation, and include that scope list when sending users to Cloudflare for consent.

Users can review the requested scopes before they consent.

Apps for both private and public use

Applications start with private visibility. Private applications can only be used by members of the account where the application was created.

To make an application available to any Cloudflare user, complete the prerequisites for public visibility.

For more information, refer to client visibility.

Client domain verification

Before an application can be made public, you must verify the client domain. Domain verification helps users confirm that the application owner controls the domain shown on the consent page.

After verification, users see a verified badge on the consent page.

For more information, refer to domain verification.

For more information, refer to OAuth clients.

Workers - New Workers bulk secrets API endpoint

Wed, 03 Jun 2026 00:00:00 GMT

You can now create, update, or delete multiple secrets for your Worker in a single request using the bulk secrets endpoint.

Include a secret with a value to create or update.
Set a secret to null to delete.
Secrets not included in the request are left unchanged.

The following example creates API_KEY, updates the already existing DB_PASSWORD, and deletes OLD_SECRET:

{
  "secrets": {
    "API_KEY": { "type": "secret_text", "name": "API_KEY", "text": "my-api-key" },
    "DB_PASSWORD": { "type": "secret_text", "name": "DB_PASSWORD", "text": "my-db-password" },
    "OLD_SECRET": null
  }
}

You can do the same from the command line using wrangler secret bulk:

npx wrangler secret bulk < secrets.json

To delete a key, set its value to null in the JSON file. Deletion is not supported with .env files.

Each request supports up to 100 total operations (creates, updates, and deletes combined).

Workers - Store Wrangler's OAuth credentials in your OS keychain

Wed, 03 Jun 2026 00:00:00 GMT

Wrangler can now store the OAuth credentials returned by wrangler login in an AES-256-GCM ↗-encrypted file, with the encryption key held in your operating system keychain. The default behavior is unchanged — credentials still live in a plaintext TOML file unless you opt in.

To opt in, run:

npx wrangler login --use-keyring

The choice is persisted across Wrangler invocations. Opt back out with npx wrangler login --no-use-keyring, or override the preference for a single command with the CLOUDFLARE_AUTH_USE_KEYRING environment variable.

wrangler whoami now reports where credentials are stored:

🔐 Credentials are stored in: Encrypted file (~/.config/.wrangler/config/default.enc) with key in macOS Keychain (service=wrangler, account=default)

Per-platform backends:

macOS uses the built-in Keychain via /usr/bin/security.
Linux uses libsecret ↗ via the secret-tool CLI from the libsecret-tools package.
Windows uses Credential Manager via @napi-rs/keyring ↗, installed on-demand the first time you opt in.

Refer to Storing OAuth credentials in the OS keychain for the full details, including the migration behavior on opt-in/opt-out and the CLOUDFLARE_AUTH_USE_KEYRING environment variable.

Workflows, Workers - Schedule Workflow instances directly from your Workflow binding

Tue, 02 Jun 2026 15:00:00 GMT

You can now attach cron schedules directly to a Workflow binding in wrangler.jsonc. Each scheduled run creates a new Workflow instance automatically, so you do not need to define a separate Worker with a scheduled handler just to trigger your Workflow on an interval.

For example, you can configure hourly, every-15-minute, or weekday schedules on the same Workflow:

{
	"workflows": [
		{
			"name": "my-scheduled-workflow",
			"binding": "MY_WORKFLOW",
			"class_name": "MyScheduledWorkflow",
			"schedules": ["0 * * * *", "*/15 * * * *", "0 9 * * MON-FRI"],
		},
	],
}

Cron workloads get all the same benefits of Workflows with built-in retries, multi-step durable execution, and configurable timeouts of Workflows.

import {
	WorkflowEntrypoint,
	WorkflowEvent,
	WorkflowStep,
} from "cloudflare:workers";

// Runs automatically on each cron schedule defined for the MY_WORKFLOW binding in wrangler.jsonc.
export class MyScheduledWorkflow extends WorkflowEntrypoint<Env> {
	async run(event: WorkflowEvent, step: WorkflowStep) {
		const data = await step.do("fetch source data", async () => {
			return await fetchSourceData();
		});

		// If this step fails, only this step is retried with the custom logic below
		await step.do(
			"process and store results",
			{
				retries: { limit: 5, delay: "30 seconds", backoff: "exponential" },
				timeout: "10 minutes",
			},
			async () => {
				await processAndStore(data);
			},
		);
	}
}

This makes it easier to build recurring, scheduled jobs such as database backups, invoice generation, report aggregation, and cleanup tasks without wiring up a separate Cron Trigger entrypoint.

Agents, Workers - Agents SDK v0.14.0: Agent Skills, messengers, scheduled tasks, Workflows, and hardened chat recovery

Tue, 02 Jun 2026 00:00:00 GMT

The latest release of the Agents SDK ↗ adds four new ways to build with @cloudflare/think: on-demand Agent Skills, chat messengers (starting with Telegram), declarative scheduled tasks, and durable reasoning steps inside Workflows. This release also significantly hardens durable chat recovery, so turns reliably ride through deploys, evictions, and stalled model streams in production.

Agent Skills (experimental)

Give an agent a catalog of on-demand instructions, resources, and scripts. A skill source adds a catalog to the system prompt, and the model activates a skill only when a task matches — so a large library of capabilities does not bloat every prompt.

import { Think, skills } from "@cloudflare/think";
import bundledSkills from "agents:skills";

export class SkillsAgent extends Think {
	getSkills() {
		return [
			bundledSkills,
			skills.r2(this.env.SKILLS_BUCKET, { prefix: "skills/" }),
		];
	}
}

import { Think, skills } from "@cloudflare/think";
import bundledSkills from "agents:skills";

export class SkillsAgent extends Think<Env> {
	getSkills() {
		return [
			bundledSkills,
			skills.r2(this.env.SKILLS_BUCKET, { prefix: "skills/" }),
		];
	}
}

The agents:skills import bundles a local ./skills directory through the Agents Vite plugin (one directory per skill, each with a SKILL.md). Skills can also load from R2 or a manifest. When skills are available, Think exposes activate_skill, read_skill_resource, and an optional run_skill_script tool. Skill loading is resilient: a duplicate or failing source is skipped with a warning instead of breaking the agent.

Agent Skills are experimental, and script execution in particular is early. The API may change in a future release. We would love your feedback — tell us what you are building and what is missing in the Agents repository ↗.

Messengers

Connect a Think agent directly to a chat platform. Think owns the webhook route, conversation routing, durable reply fiber, and streamed delivery back to the provider. Telegram ships as the first provider.

import { Think } from "@cloudflare/think";
import {
	defineMessengers,
	ThinkMessengerStateAgent,
} from "@cloudflare/think/messengers";
import telegramMessenger from "@cloudflare/think/messengers/telegram";

export { ThinkMessengerStateAgent };

export class SupportAgent extends Think {
	getMessengers() {
		return defineMessengers({
			telegram: telegramMessenger({
				token: this.env.TELEGRAM_BOT_TOKEN,
				userName: "support_bot",
				secretToken: this.env.TELEGRAM_WEBHOOK_SECRET_TOKEN,
			}),
		});
	}
}

import { Think } from "@cloudflare/think";
import {
	defineMessengers,
	ThinkMessengerStateAgent,
} from "@cloudflare/think/messengers";
import telegramMessenger from "@cloudflare/think/messengers/telegram";

export { ThinkMessengerStateAgent };

export class SupportAgent extends Think<Env> {
	getMessengers() {
		return defineMessengers({
			telegram: telegramMessenger({
				token: this.env.TELEGRAM_BOT_TOKEN,
				userName: "support_bot",
				secretToken: this.env.TELEGRAM_WEBHOOK_SECRET_TOKEN,
			}),
		});
	}
}

Each Chat SDK thread maps to its own Think sub-agent by default, so group chats and direct messages do not share memory. Multiple bots, custom conversation routing, and custom providers are all supported.

Scheduled tasks

Declare recurring, timezone-aware prompts and handlers with a typed domain-specific language (DSL). Think reconciles the declarations on startup and re-arms the next occurrence after each run, backed by durable idempotent submissions.

import { Think, defineScheduledTasks } from "@cloudflare/think";

export class DigestAgent extends Think {
	getScheduledTasks() {
		return defineScheduledTasks({
			weeklyCommitReport: {
				schedule: "every week on monday at 09:00",
				prompt:
					"Compile my GitHub commits for the last week and summarize them.",
			},
			workout: {
				schedule: "every day at 08:00 in Europe/London",
				prompt: "Start my workout.",
			},
		});
	}
}

import { Think, defineScheduledTasks } from "@cloudflare/think";

export class DigestAgent extends Think<Env> {
	getScheduledTasks() {
		return defineScheduledTasks({
			weeklyCommitReport: {
				schedule: "every week on monday at 09:00",
				prompt:
					"Compile my GitHub commits for the last week and summarize them.",
			},
			workout: {
				schedule: "every day at 08:00 in Europe/London",
				prompt: "Start my workout.",
			},
		});
	}
}

Think Workflows

Run a model-driven reasoning step inside a Cloudflare Workflow with ThinkWorkflow and step.prompt(), with durable typed structured output, long waits, and approval gates.

import { z } from "zod";
import { ThinkWorkflow } from "@cloudflare/think/workflows";

const draftSchema = z.object({
	title: z.string(),
	summary: z.string(),
	labels: z.array(z.string()),
});

export class TriageWorkflow extends ThinkWorkflow {
	async run(event, step) {
		const draft = await step.prompt("triage-issue", {
			prompt: `Triage issue #${event.payload.issueNumber}`,
			output: draftSchema,
			timeout: "3 days",
		});

		await step.do("apply-labels", async () => {
			await this.agent.applyLabels(draft.labels);
		});
	}
}

import { z } from "zod";
import { ThinkWorkflow } from "@cloudflare/think/workflows";
import type { ThinkWorkflowStep } from "@cloudflare/think/workflows";
import type { AgentWorkflowEvent } from "agents/workflows";

const draftSchema = z.object({
	title: z.string(),
	summary: z.string(),
	labels: z.array(z.string()),
});

export class TriageWorkflow extends ThinkWorkflow<TriageAgent, Params> {
	async run(event: AgentWorkflowEvent<Params>, step: ThinkWorkflowStep) {
		const draft = await step.prompt("triage-issue", {
			prompt: `Triage issue #${event.payload.issueNumber}`,
			output: draftSchema,
			timeout: "3 days",
		});

		await step.do("apply-labels", async () => {
			await this.agent.applyLabels(draft.labels);
		});
	}
}

Production hardening for durable chat recovery

Durable chat turns have always been designed to survive a mid-turn deploy or Durable Object eviction. This release is a major hardening pass on that machinery for production.

Better recovery during deploys. Turns now ride through continuous deploys and evictions without losing completed work or re-running tools that already ran.
A live "recovering…" signal. useAgentChat exposes a new isRecovering flag, so a recovering turn shows progress instead of looking frozen. Most UIs render isStreaming || isRecovering as "busy".
Stalled streams recover. Set chatStreamStallTimeoutMs to route a hung provider stream into the same recovery path instead of leaving an infinite spinner.
Sub-agents re-attach. On parent recovery, an in-flight agentTool() child is re-attached to its result rather than abandoned and re-run, so long-running children no longer lose work under deploys.

MCP transport improvements

Resumable streams — In-flight tool calls over Server-Sent Events (SSE) survive a dropped connection. Clients reconnect with Last-Event-ID and replay anything they missed.
Readable server IDs — addMcpServer accepts an optional id, so tools surface as readable keys (for example tool_github_create_pull_request) instead of opaque connection IDs.
Better handling of concurrent requests — Overlapping JSON-RPC requests are now correctly correlated to their responses across the HTTP and RPC transports.

Other improvements

Compaction — A Session's tokenCounter now also drives the compaction boundary decision ("what to compress"), not just the fire/no-fire trigger.
@cloudflare/worker-bundler — Adds a virtualModules option to createWorker to provide in-memory module source during bundling.
Client-tool continuations — Parallel tool results now coalesce into a single continuation, immediate resume requests attach to the pending continuation, and server-side needsApproval continuations resume reliably after approval.

Logs - New Turnstile Events Logpush dataset in Cloudflare Logs

Mon, 01 Jun 2026 00:00:00 GMT

Cloudflare has updated Logpush datasets:

New datasets

Turnstile Events: A new dataset with fields including ASN, Action, BrowserMajor, BrowserName, ClientIP, CountryCode, EventType, Hostname, OSMajor, OSName, Sitekey, Timestamp, and UserAgent.

Cloudflare One Client - Cloudflare One Client for macOS (version 2026.5.1155.1)

Fri, 29 May 2026 00:55:38 GMT

A new Beta release for the macOS Cloudflare One Client is now available on the beta releases downloads page.

This release introduces the new Cloudflare One Client UI for macOS! You can expect a cleaner and more intuitive design as well as easier access to common actions and information. Here are some of the many things we have found our users appreciate:

Right click context menu to access the most common client actions quickly
Built-in captive portal login experience

Additional Changes and improvements

The client now applies DNS search suffixes configured in your device profile / network policy. Administrators can push a list of DNS search domains that the client appends to single-label queries, alongside any system-configured suffixes. See DNS search suffixes for details.
Administrators can now control which virtual networks (VNETs) are available to which users via WARP device profile settings in the Zero Trust dashboard. Previously, every VNET in the organization was visible to every device; you can now scope the VNET picker per profile so users only see the networks relevant to them. See VNET availability for details.
Added a local-file signal source for Emergency Disconnect. In addition to the existing HTTPS polling mechanism, administrators can now configure WARP to monitor for a file on disk; the presence of the file triggers an emergency disconnect even if both Cloudflare and your own infrastructure are unreachable. Either signal being asserted triggers disconnect; both must be cleared for normal operation to resume.
Added new warp-cli debug commands for interactive connection diagnosis. See Extra debug logging for details.
The local DNS proxy now supports DNSSEC passthrough. DNSSEC-signed responses are forwarded to the application intact (including DO/AD bits and RRSIG records), so applications that validate DNSSEC locally — including resolvers and the dig/drill tooling — work correctly through the client.
Added a new MDM format for organization-wide settings, including a cleaner way to configure the compliance environment (e.g. FedRAMP). The previous per-configuration approach still works, but the new format is now recommended. See the updated Cloudflare One MDM documentation for details.
Client Certificate device-posture checks now support template variables (e.g. ${serial_number}, ${device_uuid}) in the Subject Alternative Name field, matching what the documentation has always claimed. Previously only the Common Name field accepted variables, which broke posture rules that pinned identity to a SAN entry.
Fixed the in-client captive-portal browser rendering a blank "Success" page on some airline Wi-Fi networks (United inflight Wi-Fi was the reported case). The browser now reliably loads the airline's real portal page so users can complete sign-in from inside the client instead of having to open a separate browser.
Fixed an issue in proxy mode where hostnames containing underscores (e.g. ai_app.com) were rejected, breaking apps that depend on such hostnames (notably ChatGPT sandbox apps). The local proxy now accepts underscore-containing hostnames in CONNECT requests.

Known issues

Registration may hang at "Checking your organization configuration" due to IPC errors. A system reboot should resolve the error, allowing registration to proceed.
Split tunnel list configuration is not available in the new UI. Management of split tunnel entries is currently only possible via warp-cli tunnel ip and warp-cli tunnel host. UI support will be added in a future release.

Cloudflare One Client - Cloudflare One Client for Windows (version 2026.5.1155.1)

Fri, 29 May 2026 00:55:37 GMT

A new Beta release for the Windows Cloudflare One Client is now available on the beta releases downloads page.

This release introduces the new Cloudflare One Client UI for Windows! You can expect a cleaner and more intuitive design as well as easier access to common actions and information. Here are some of the many things we have found our users appreciate:

Right click context menu to access the most common client actions quickly
Built-in captive portal login experience

Additional Changes and improvements

The client now applies DNS search suffixes configured in your device profile / network policy. Administrators can push a list of DNS search domains that the client appends to single-label queries, alongside any system-configured suffixes. See DNS search suffixes for details.
Administrators can now control which virtual networks (VNETs) are available to which users via WARP device profile settings in the Zero Trust dashboard. Previously, every VNET in the organization was visible to every device; you can now scope the VNET picker per profile so users only see the networks relevant to them. See VNET availability for details.
Added mandatory authentication. When enabled via MDM, the Cloudflare One Client blocks all Internet traffic from the moment the machine boots until the user authenticates, closing the visibility gap on newly deployed devices and during re-authentication. See the announcement blog and documentation for details.
Added a local-file signal source for Emergency Disconnect. In addition to the existing HTTPS polling mechanism, administrators can now configure WARP to monitor for a file on disk; the presence of the file triggers an emergency disconnect even if both Cloudflare and your own infrastructure are unreachable. Either signal being asserted triggers disconnect; both must be cleared for normal operation to resume.
Added new warp-cli debug commands for interactive connection diagnosis. See Extra debug logging for details.
The local DNS proxy now supports DNSSEC passthrough. DNSSEC-signed responses are forwarded to the application intact (including DO/AD bits and RRSIG records), so applications that validate DNSSEC locally — including resolvers and the dig/drill tooling — work correctly through the client.
Added a new MDM format for organization-wide settings, including a cleaner way to configure the compliance environment (e.g. FedRAMP). The previous per-configuration approach still works, but the new format is now recommended. See the updated Cloudflare One MDM documentation for details.
Client Certificate device-posture checks now support template variables (e.g. ${serial_number}, ${device_uuid}) in the Subject Alternative Name field, matching what the documentation has always claimed. Previously only the Common Name field accepted variables, which broke posture rules that pinned identity to a SAN entry.
The UseWebView2 registry value (HKLM\SOFTWARE\Cloudflare\CloudflareWARP\UseWebView2 = y) is once again honored by the new GUI for authentication, so administrators who prefer the embedded WebView2 browser for sign-in can opt back in. This setting was effectively ignored in the previous release; the default browser was always used. This key is now also honored for re-authentications.
Fixed a crash in the authentication browser when navigating to a site that prompts for browser permissions (microphone, camera, notifications, etc.). The same fix had previously landed for the captive-portal browser; this extends it to the auth browser.
Fixed an issue in proxy mode where hostnames containing underscores (e.g. ai_app.com) were rejected, breaking apps that depend on such hostnames (notably ChatGPT sandbox apps). The local proxy now accepts underscore-containing hostnames in CONNECT requests.

Known issues

An error indicating that Microsoft Edge can't read and write to its data directory may be displayed during captive portal login; this error is benign and can be dismissed.
Registration may hang at "Checking your organization configuration" due to IPC errors. A system reboot should resolve the error, allowing registration to proceed.
Split tunnel list configuration is not available in the new UI. Management of Split Tunnel entries is currently only possible via warp-cli tunnel ip and warp-cli tunnel host. UI support will be added in a future release.
Windows ARM may prompt the user to close running applications while trying to install this version. Simply click “Ok” with the default highlighted option.
DNS resolution may be broken when the following conditions are all true:
- The client is in Secure Web Gateway without DNS filtering (tunnel-only) mode.
- A custom DNS server address is configured on the primary network adapter.
- The custom DNS server address on the primary network adapter is changed while the client is connected.
  To work around this issue, please reconnect the client by selecting "disconnect" and then "connect" in the client user interface.

Agents - Share sandbox previews through Cloudflare Tunnel

Fri, 29 May 2026 00:00:00 GMT

Sandboxes can expose a service running inside the container on a public preview URL through the sandbox.tunnels namespace. The SDK uses cloudflared inside the sandbox so you can share a running service without configuring exposePort() or a custom domain.

By default, sandbox.tunnels.get(port) creates a quick tunnel ↗ on a zero-config *.trycloudflare.com URL — no Cloudflare account, DNS record, or custom domain required. This is perfect for quick development and for .workers.dev deployments.

import { getSandbox } from "@cloudflare/sandbox";

const sandbox = getSandbox(env.Sandbox, "my-sandbox");
await sandbox.startProcess("python -m http.server 8080");

const tunnel = await sandbox.tunnels.get(8080);
console.log(tunnel.url); // → https://random-words-here.trycloudflare.com

import { getSandbox } from "@cloudflare/sandbox";

const sandbox = getSandbox(env.Sandbox, "my-sandbox");
await sandbox.startProcess("python -m http.server 8080");

const tunnel = await sandbox.tunnels.get(8080);
console.log(tunnel.url); // → https://random-words-here.trycloudflare.com

Named tunnels

For more control you can create a named tunnel through sandbox.tunnels.get(port, { name }). A named tunnel binds a hostname (<name>.<your-zone>) backed by a Cloudflare Tunnel and a CNAME record on your zone resulting in something like https://my-app-preview.example.com ↗.

Unlike quick tunnels, which generate a new random URL each time, a named tunnel produces a persistent URL that survives container restarts. This makes named tunnels suitable for production use cases where you want control over the tunnel and it's origin.

const tunnel = await sandbox.tunnels.get(8080, { name: "my-app-preview" });
console.log(tunnel.url); // → https://my-app-preview.example.com

const tunnel = await sandbox.tunnels.get(8080, { name: "my-app-preview" });
console.log(tunnel.url); // → https://my-app-preview.example.com

Calling sandbox.destroy() tears down the Cloudflare Tunnel and the associated DNS record alongside the container, so you do not leave dangling tunnels or records behind.

Upgrade

To update to the latest version:

npm i @cloudflare/sandbox@latest

yarn add @cloudflare/sandbox@latest

pnpm add @cloudflare/sandbox@latest

bun add @cloudflare/sandbox@latest

For full API details, refer to the Sandbox tunnels reference.

D1 - D1 migrations support nested layouts via `migrations_pattern`

Fri, 29 May 2026 00:00:00 GMT

You can now point wrangler d1 migrations apply at a nested migrations layout — such as the one produced by Drizzle ↗ (migrations/0001_init/migration.sql) — using the new migrations_pattern D1 binding config:

{
	"d1_databases": [
		{
			"binding": "DB",
			"database_name": "my-database",
			"database_id": "<UUID>",
			"migrations_dir": "migrations",
			"migrations_pattern": "migrations/*/migration.sql",
		},
	],
}

migrations_pattern is a glob (relative to your Wrangler config file) used to discover migration files. It defaults to ${migrations_dir}/*.sql, so existing projects keep working unchanged. Each migration's name is recorded in the migrations table as a path relative to migrations_dir.

To learn more, visit D1's migrations documentation.

Logs - Updated fields across multiple Logpush datasets in Cloudflare Logs

Fri, 29 May 2026 00:00:00 GMT

Cloudflare has updated Logpush datasets:

Updated fields in existing datasets

DEX Device State Events (added): DeviceRegistrationProfileID.
Gateway HTTP (added): AddedHeaders, DeletedHeaders, and SetHeaders.
HTTP requests (added): MatchedRules.

For the complete field definitions for each dataset, refer to Logpush datasets.

Radar - TLS bug detection in the Cloudflare Radar post-quantum checker

Fri, 29 May 2026 00:00:00 GMT

The Radar post-quantum TLS support checker ↗ now also reports TLS bugs detected during the handshake test. When a scanned host exhibits compatibility issues, the results include details on the specific bugs detected, along with guidance on how to investigate and remediate each issue. The bugs section only appears for hosts where issues are found.

The following TLS bugs are detected:

Split ClientHello — The connection fails with a fragmented post-quantum ClientHello but succeeds with classical handshakes. Typically caused by middleboxes or firewalls that cannot reassemble split TLS messages.
HRR Failure — The server sends a HelloRetryRequest but fails to complete the handshake afterward.
Unknown Keyshare — The server cannot handle unknown key exchange algorithms and fails instead of responding with a HelloRetryRequest as required by the TLS 1.3 specification.

Bug detection data is available through the existing /post_quantum/tls/support endpoint.

Visit the Post-Quantum Encryption ↗ page to test a host.

Realtime - Cloudflare's Realtime WebSocket adapter now auto-reconnects and buffers WebRTC media

Fri, 29 May 2026 00:00:00 GMT

Cloudflare Realtime SFU is a WebRTC Selective Forwarding Unit that runs on Cloudflare's global network, so you can route live audio, video, and data between WebRTC clients around the world without managing SFU infrastructure or regions.

When you use the WebSocket adapter to stream WebRTC media to a WebSocket endpoint, the adapter now auto-reconnects and buffers audio and video after brief endpoint disconnects or restarts.

Streaming WebRTC media to WebSocket endpoints

Many teams also use Realtime SFU as the media layer for backend applications, such as transcription, recording, note-taking, and agentic media-processing services. These systems often need to consume live WebRTC audio or video from the SFU in backend infrastructure, including Durable Objects, Workers, Containers, or external services, without running a WebRTC client themselves.

The WebSocket adapter bridges that gap by streaming WebRTC media from the SFU to a standard WebSocket endpoint as application-consumable payloads: PCM audio frames and JPEG video frames.

What changed

When you use the WebSocket adapter in Stream mode (egress) to send live audio or video from the SFU to your own WebSocket endpoint, the SFU now automatically reconnects after brief endpoint disconnects or restarts. This is especially helpful for long-running media pipelines where the WebSocket endpoint may briefly restart while a recording, transcription, or live analysis job is still in progress.

Previously, a brief disconnect from your WebSocket endpoint could close the adapter and require your application to recreate it before media could resume. Now, the SFU retries the same endpoint for up to 5 seconds with no API change required. If the endpoint comes back within that window, audio and video delivery resumes automatically.

The reconnect behavior also includes live-first media buffering, so brief interruptions reduce media loss without replaying stale video.

Reconnect behavior

During reconnect:

Audio uses a short bounded backlog to reduce audible loss. If the interruption lasts longer than the backlog can cover, older audio may be dropped.
Video resumes from the latest available JPEG frame instead of replaying stale frames.
Recovery is best effort and does not guarantee gapless or exactly-once delivery.

If the endpoint remains unavailable after the 5-second reconnect window, the adapter closes and must be recreated.

Security Center - Security scans more frequent

Fri, 29 May 2026 00:00:00 GMT

Security Insights scans now run more often. Cloudflare scans Free accounts every 7 days, Pro and Business accounts every 3 days, and Enterprise accounts daily.

In addition, all accounts and zones now receive scans by default. You no longer need to enable scans before Cloudflare checks your account for misconfigurations, vulnerabilities, and other security risks.

Granular on-demand scans are now available on any plan. You can trigger an on-demand scan for any zone, insight, insight type from the Cloudflare dashboard in order to quickly re-check your security posture after remediating an issue.

To learn more, refer to the Security Insights documentation.

Access - Tool and prompt aliases for MCP server portals

Thu, 28 May 2026 00:00:00 GMT

When you connect third-party MCP servers through MCP server portals, you have no control over how the server author named tools or wrote descriptions. Unclear names make it harder for AI agents to select the right tool and harder for users to understand what is available.

You can now rename tools and prompts and rewrite their descriptions directly on the portal, without modifying the upstream server. For example, a tool named super_cool_tool can become search_customer_records with a description tailored to your organization.

Modified tools display a Modified label in the tools list so administrators can see which tools have been customized at a glance.

Aliases override the metadata that MCP clients receive. You can set them at two levels:

Per portal: Applies only within a specific portal. Takes precedence over server-level aliases.
Per server: Applies across all portals that use the server.

You can reset an alias at any time to restore the original upstream name.

For more information, refer to Tool and prompt aliases.

Browser Run - Use Browser Run Quick Actions directly from Workers

Thu, 28 May 2026 00:00:00 GMT

You can now call Browser Run Quick Actions directly from a Cloudflare Worker using the quickAction() method on the browser binding. This simplifies how Workers interact with Browser Run by removing the need for API tokens or external HTTP requests. Your Worker communicates with Browser Run directly over Cloudflare's network, resulting in simpler code and lower latency.

With the quickAction() method you can:

Capture screenshots from URLs or HTML
Generate PDFs with custom styling, headers, and footers
Extract HTML content from fully rendered pages
Convert pages to Markdown
Extract structured JSON using AI
Scrape elements with CSS selectors
Get all links from a page
Capture snapshots (HTML + screenshot in one request)

To get started, add a browser binding to your Wrangler configuration:

{
  "compatibility_date": "2026-03-24",
  "browser": {
    "binding": "BROWSER"
  }
}

compatibility_date = "2026-03-24"

[browser]
binding = "BROWSER"

Then call any Quick Action directly from your Worker. For example, to capture a screenshot:

const screenshot = await env.BROWSER.quickAction("screenshot", {
	url: "https://www.cloudflare.com/",
});

const screenshot = await env.BROWSER.quickAction("screenshot", {
  url: "https://www.cloudflare.com/",
});

The quickAction() method requires a compatibility date of 2026-03-24 or later.

For setup instructions and the full list of available actions, refer to Browser Run Quick Actions.

Cloudflare Mesh, Cloudflare One - High availability replica management for Cloudflare Mesh

Thu, 28 May 2026 00:00:00 GMT

The Cloudflare Mesh dashboard now shows per-replica details for high availability nodes. You can see which replica is active, view each replica's Mesh IP and connection details, and manually trigger failover — all from the node detail page.

What's new

Replica tabs on the node detail page — switch between replicas to see each one's Mesh IP, edge data center, origin IP, platform, version, and uptime.
Active/passive badges identify which replica is currently routing traffic.
Manual failover — promote a passive replica to active with a single click. The previous active replica switches to standby.
HA badge in the overview table identifies nodes running multiple replicas.
Active replica IP shown in the overview table — the dashboard now resolves which replica is active and displays the correct Mesh IP.

Manual failover

To manually promote a passive replica:

In the Cloudflare dashboard ↗, go to Networking > Mesh.
Select an HA-enabled node.
Select the passive replica tab.
Select Promote to active and confirm.

Traffic reroutes to the promoted replica immediately. Refer to High availability for details on failover behavior.

Containers - Wrangler supports SSH ProxyCommand for Containers

Thu, 28 May 2026 00:00:00 GMT

Wrangler supports using wrangler containers ssh as an OpenSSH ProxyCommand for Containers. This lets your local SSH client connect to a running Container through Wrangler.

ssh -o ProxyCommand="wrangler containers ssh %h" cloudchamber@<INSTANCE_ID>

When standard input and output are piped, Wrangler forwards data to the SSH server in the Container. You can also pass --stdio to force this mode.

For more information, refer to the SSH documentation.

Email Service - Send emails with named recipient addresses

Thu, 28 May 2026 00:00:00 GMT

You can now send emails with display names on recipient addresses in addition to the existing from support. Pass an object with email and an optional name field for to, cc, bcc, replyTo, or from:

src/index.jsjs

export default {
	async fetch(request, env) {
		const response = await env.EMAIL.send({
			from: { email: "support@example.com", name: "Support Team" },
			to: { email: "jane@example.com", name: "Jane Doe" },
			cc: [
				"manager@company.com",
				{ email: "team@company.com", name: "Engineering Team" },
			],
			subject: "Welcome!",
			html: "<h1>Thanks for joining!</h1>",
			text: "Thanks for joining!",
		});

		return Response.json({ messageId: response.messageId });
	},
};

src/index.tsts

export default {
	async fetch(request, env): Promise<Response> {
		const response = await env.EMAIL.send({
			from: { email: "support@example.com", name: "Support Team" },
			to: { email: "jane@example.com", name: "Jane Doe" },
			cc: [
				"manager@company.com",

Pipelines - Pipelines pricing announced

Thu, 28 May 2026 00:00:00 GMT

Cloudflare Pipelines is a streaming data platform that ingests events, transforms them with SQL, and writes to R2 as JSON, Parquet, or Apache Iceberg ↗ tables. Pipelines now has published pricing based on two usage dimensions: the volume of data processed by SQL transforms and the volume of data delivered to sinks. Ingress into a Pipeline stream is free.

Billing is not yet enabled. We will provide at least 30 days notice before we start charging for Pipelines usage.

Pipelines pricing model is designed to charge per GB based on what you use:

Streams (ingress): Free, regardless of volume.
SQL transforms: $0.04 / GB for stateless transforms (filter, reshape, unnest, cast, compute).
Sinks: $0.03 / GB for JSON, $0.06 / GB for Parquet or Iceberg output.

Workers Free plans include 1 GB / month for each dimension. Workers Paid plans include 50 GB / month.

For full pricing details and billing examples, refer to Pipelines pricing.

R2, R2 Data Catalog - R2 Data Catalog pricing announced

Thu, 28 May 2026 00:00:00 GMT

R2 Data Catalog is a managed Apache Iceberg ↗ data catalog built directly into R2 buckets, queryable by any Iceberg-compatible engine such as Spark, Snowflake, and DuckDB. R2 Data Catalog now has published pricing for catalog operations and table compaction, in addition to standard R2 storage and operations.

Billing is not yet enabled. We will provide at least 30 days notice before we start charging for R2 Data Catalog usage.

Pricing is based on two dimensions:

Catalog operations: $9.00 / million operations for metadata requests such as creating tables, reading table metadata, and updating table properties.
Compaction: $0.005 / GB processed and $2.00 / million objects processed. These charges only apply when automatic compaction is turned on for a table.

Both dimensions include a monthly free tier: 1 million catalog operations, 10 GB of compaction data processed, and 1 million compaction objects processed.

For full pricing details and billing examples, refer to R2 Data Catalog pricing.

R2, R2 Data Catalog - R2 Data Catalog gets a dedicated dashboard experience

Thu, 28 May 2026 00:00:00 GMT

R2 Data Catalog is a managed Apache Iceberg ↗ data catalog built directly into your R2 bucket. It exposes a standard Iceberg REST catalog interface so you can connect query engines like Spark, Snowflake, DuckDB, and R2 SQL to your data in R2.

R2 Data Catalog now has a dedicated section in the Cloudflare dashboard, replacing the previous settings panel embedded in R2 bucket configuration. The new experience includes:

Catalog overview — View all your catalogs in one place with catalog request counts, bucket sizes, and table maintenance status at a glance.
Guided setup wizard — Create a catalog in three steps: choose or create an R2 bucket, configure table maintenance (compaction and snapshot expiration), and review. The wizard creates the bucket and generates a service credential automatically.
Settings management — A dedicated settings page for each catalog with sections for general configuration, table maintenance, service credentials, and disabling the catalog. You can now enable and configure snapshot expiration directly from the dashboard.
Built-in metrics — Five charts on each catalog's metrics tab: bytes compacted, files compacted, catalog requests, storage size, and snapshots expired.

To get started, go to R2 Data Catalog in the Cloudflare dashboard or refer to the getting started guide and manage catalogs documentation.

R2 SQL - R2 SQL pricing announced

Thu, 28 May 2026 00:00:00 GMT

R2 SQL is a serverless, distributed query engine that runs SQL against Apache Iceberg ↗ tables stored in R2 Data Catalog. R2 SQL now has published pricing based on a single dimension: the volume of compressed data scanned to execute your queries. At $2.50 / TB ($0.0025 / GB), R2 SQL is priced at half the cost of AWS Athena and less than half of Google BigQuery on-demand.

Billing is not yet enabled. We will provide at least 30 days notice before we start charging for R2 SQL usage.

Data scanned is measured on compressed bytes read from R2 object storage. This matches what you see in your R2 bucket — if a Parquet file is 100 MB on disk, scanning that file bills for 100 MB. Each query has a minimum billing increment of 10 MB.

All plans include 10 GB of data scanned per month. Standard R2 storage and operations and R2 Data Catalog charges apply separately.

For full pricing details and billing examples, refer to R2 SQL pricing.

Realtime - Record specific participant audio tracks in RealtimeKit

Thu, 28 May 2026 00:00:00 GMT

You can now record specific participant audio tracks in RealtimeKit with track recording. Track recording creates separate WebM files for each participant instead of a single composite recording, which is useful for post-processing, transcription, and regulated or content-sensitive workflows.

To record specific participants, pass user_ids when starting a track recording:

curl --request POST \
  --url https://api.cloudflare.com/client/v4/accounts/<account_id>/realtime/kit/<app_id>/recordings/track \
  --header 'Authorization: Bearer <api_token>' \
  --header 'Content-Type: application/json' \
  --data '{
  "meeting_id": "97440c6a-140b-40a9-9499-b23fd7a3868a",
  "user_ids": ["user-123", "user-456"]
}'

To pass user_ids for selective track recording, use the following minimum SDK versions:

Web Core: @cloudflare/realtimekit version 1.4.0 or later
Web UI Kit: @cloudflare/realtimekit-ui, @cloudflare/realtimekit-react-ui, or @cloudflare/realtimekit-angular-ui version 1.1.2 or later
Android Core or iOS Core: version 2.0.0 or later
Android UI Kit or iOS UI Kit: version 1.1.0 or later

RealtimeKit provides SDKs and UI components so that you can build your own meeting experience on Cloudflare's global WebRTC infrastructure. Teams today build products ranging from telehealth to education on RealtimeKit for global audiences. You can get started today with our Quickstart or take a look at our Cloudflare Meet repo ↗ as a reference.

Cloudflare One, Gateway - Write regex using natural language in Cloudflare One

Wed, 27 May 2026 00:00:00 GMT

Cloudflare Gateway policy selectors which support regular expressions can now be authored in the dashboard using natural language. When building a policy with a regex-based selector (like matches regex), you can describe what you want to match in plain English and the Cloudflare Agent will generate and validate a corresponding regular expression.

To get started, select a regex-compatible selector in the Gateway policy builder and select the icon. You'll see an input field for natural language, such as "any URL starting with /api/v1" or ".com, .net, and .app hosts which contain gooogle in the host."

You can also use the tool to explain existing regular expressions. If a policy already contains a regex pattern, you can instantly generate a plain-language description.

A built-in feedback mechanism allows you to rate each interaction to help improve output quality over time.

For more information, refer to Cloudflare One firewall policies and expect to see the same functionality supported soon in Data loss prevention profiles.

Cloudflare Images - Transformation flows in Images

Wed, 27 May 2026 00:00:00 GMT

Flows are automated rules that pair conditions (such as file extension, URL path, or query parameter) with parameters. Set up a flow to automatically apply image optimization to matching requests on your zone without writing code or changing URLs.

There are two modes for transformation flows:

Provider flows — Migrate from another image optimization service. Your existing URLs continue to work while Cloudflare rewrites provider-specific parameters to their Cloudflare equivalents. Currently, Cloudflare supports provider flows for Fastly Image Optimizer.
Custom flows — Define your own conditions and actions for use cases like automatic format conversion, responsive sizing with width=auto, or directory-based optimization.

To get started, go to Images > Transformations > Automation in the Cloudflare dashboard ↗.

Learn more about transformation flows.

Cloudflare Tunnel, Cloudflare Tunnel for SASE - Cloudflare Tunnel now runs connectivity pre-checks at startup

Wed, 27 May 2026 00:00:00 GMT

Starting with cloudflared version 2026.5.2 ↗, Cloudflare Tunnel automates the entire connectivity pre-checks workflow directly inside the binary. Previously, customers had to install dig and netcat and run those commands by hand to verify their environment. Now cloudflared does it natively at startup — and surfaces actionable remediation when something is blocked.

On every cloudflared tunnel run (and cloudflared tunnel diag), the binary now natively checks:

DNS resolution — region1.v2.argotunnel.com and region2.v2.argotunnel.com resolve to valid Cloudflare IPs.
Transport connectivity — outbound UDP (QUIC) and TCP (HTTP/2) on port 7844.
Management API — outbound TCP/443 to api.cloudflare.com for software updates.

Results are printed in a scannable CLI table with three states:

✅ Pass — the check succeeded.
⚠️ Warn — a non-blocking issue, for example the Management API is unreachable so automatic updates will not work, but the tunnel will still come up.
❌ Fail — a blocking issue, with a specific remediation hint (for example, Allow outbound UDP on port 7844).

If DNS is unresolvable, or both UDP and TCP fail on port 7844, cloudflared exits early with the failure rather than looping on opaque failed to dial errors.

Pre-checks now run automatically on every start, which also catches regressions like overnight firewall policy changes — no need to remember to rerun the troubleshooting guide.

To get the new behavior, upgrade cloudflared to version 2026.5.2 or later. For more details, refer to the Connectivity pre-checks documentation.

Split tunnel list configuration is not available in the new UI. Management of split tunnel entries is currently only possible via warp-cli tunnel ip and warp-cli tunnel host. UI support will be added in a future release.

Cache - BYPASS status now returned for uncacheable responses

Tue, 26 May 2026 00:00:00 GMT

Cloudflare now returns a BYPASS cache status whenever a response is not cacheable, instead of the previous mix of BYPASS and MISS that depended on why Cloudflare chose not to cache the response.

There are multiple reasons Cloudflare may refuse to cache a response — for example, the response exceeds the maximum cacheable file size for your plan, the origin sends Cache-Control: no-cache, private, or max-age=0, the response includes a Set-Cookie header, or the request includes an Authorization header.

Previously, only some of these conditions returned BYPASS. Others — such as responses exceeding the maximum cacheable file size — returned MISS on every request, regardless of whether Origin Cache Control was on or off. Because the response could never be cached, every subsequent request also returned MISS, which looked indistinguishable from a broken cache and made it hard to tell whether Cloudflare was trying and failing to cache the asset or had deliberately chosen not to cache it.

BYPASS now consistently signals that Cloudflare refused to cache the response, regardless of the reason. MISS is reserved for cacheable responses that simply were not in the local cache at request time.

What to expect in your analytics

After this change rolls out, you should see:

MISS rate decreases: Uncacheable responses no longer count as cache misses.
BYPASS rate increases: These same responses are now reported as bypasses.
Cache hit ratio increases: Hit ratio calculations no longer include uncacheable traffic that could never have been cached, giving you a more accurate view of cache effectiveness.

Your total request volume and origin traffic are unchanged — only the cache status label is different.

Browser cache TTL behavior is preserved

The cache status label is the only thing changing — browser cache TTL handling for any given response is identical to what it was before:

Responses that historically returned MISS because Cloudflare refused to cache them (for example, responses over the maximum cacheable file size) now return BYPASS, but continue to have browser cache TTL applied — exactly as they did when they were labeled MISS.
Responses that historically returned BYPASS and skipped browser cache TTL continue to skip browser cache TTL.

In both cases, the decision to apply browser cache TTL depends on the underlying reason Cloudflare did not cache the response, not on the new BYPASS label.

Flagship - Flagship now in public beta

Tue, 26 May 2026 00:00:00 GMT

Flagship is now in public beta. Evaluate feature flags directly from Cloudflare Workers with no outbound HTTP calls, using globally distributed flag configuration backed by Workers KV and Durable Objects. Flagship supports typed flag values, targeting rules, percentage rollouts, audit history, and OpenFeature-compatible SDKs.

Evaluate a flag from a Worker in a few lines of code:

src/index.jsjs

export default {
	async fetch(request, env) {
		const showNewCheckout = await env.FLAGS.getBooleanValue(
			"new-checkout",
			false,
		);

		return new Response(showNewCheckout ? "New checkout" : "Standard checkout");
	},
};

src/index.tsts

export default {
	async fetch(request: Request, env: Env): Promise<Response> {
		const showNewCheckout = await env.FLAGS.getBooleanValue("new-checkout", false);

		return new Response(
			showNewCheckout ? "New checkout" : "Standard checkout",
		);
	},
} satisfies ExportedHandler<Env>;

Start creating flags from the Cloudflare dashboard today. Refer to the Flagship documentation to get started.

AI Gateway - Call any AI model through AI Gateway's new REST API

Thu, 21 May 2026 00:00:00 GMT

AI Gateway now uses the AI REST API on api.cloudflare.com. You can call any model — whether from OpenAI, Anthropic, Google, or hosted on Workers AI — through one unified API, using the same endpoints and authentication regardless of provider. Four endpoints are available:

POST /ai/run — universal endpoint for all models and modalities
POST /ai/v1/chat/completions — OpenAI SDK compatible
POST /ai/v1/responses — OpenAI Responses API compatible
POST /ai/v1/messages — Anthropic SDK compatible

curl -X POST "https://api.cloudflare.com/client/v4/accounts/$CLOUDFLARE_ACCOUNT_ID/ai/v1/chat/completions" \
  --header "Authorization: Bearer $CLOUDFLARE_API_TOKEN" \
  --header "Content-Type: application/json" \
  --data '{
    "model": "openai/gpt-5.5",
    "messages": [{"role": "user", "content": "What is Cloudflare?"}]
  }'

All AI Gateway features — logging, caching, rate limiting, and guardrails — are applied automatically. Third-party models are billed through Unified Billing, so you do not need to manage separate provider API keys.

Third-party model requests are routed through your account's default gateway, which is created automatically on first use. To route requests through a specific gateway, add the cf-aig-gateway-id header.

If you are already calling Workers AI models through the existing REST API, that path (/ai/run/@cf/{model}) continues to work. To call Workers AI models through AI Gateway, use the @cf/ model prefix (for example, @cf/moonshotai/kimi-k2.6) and include the cf-aig-gateway-id header to specify which gateway to route through.

For more details and examples, refer to the REST API documentation.

Billing - Modernized Billing Profile with new payment options

Thu, 21 May 2026 00:00:00 GMT

The Billing Profile now has a modern UI and a single space that unifies billing information, payment method management and an enhanced subscriptions view under a single Subscriptions tab.

What changed

The Subscriptions tab brings billing information, payment method management, and your subscriptions together in one place. The payment management and Pay overdue balances flows now use the latest checkout as product purchase flows, so you can pay with Apple Pay, Google Pay, Link, and Instant Bank Payments via Link alongside cards and PayPal.

New cards complete 3D Secure authentication when the issuer requires it — for example, the EU under PSD2 and India under RBI.

For details, refer to the Billing Home documentation.

Cloudflare Fundamentals, Cloudflare One, Cloudflare Tunnel for SASE, Cloudflare Tunnel, Cloudflare Mesh - Granular permissions for Cloudflare Tunnel and Cloudflare Mesh

Thu, 21 May 2026 00:00:00 GMT

You can now scope Cloudflare permissions to individual Cloudflare Tunnel instances and Cloudflare Mesh nodes. Administrators can delegate access to specific Tunnels or Mesh nodes without granting account-wide control over private networking.

What is new

When you add a member or create a permission policy, the resource picker now lists Cloudflare Tunnel instances and Cloudflare Mesh nodes as scopable resource types. You can:

Grant a read-only role on a single Cloudflare Tunnel instance to a support operator for log streaming and diagnostics — without exposing other Tunnels or destructive actions.
Grant a write role on a specific Cloudflare Mesh node to an application team — without giving them access to the rest of your private network.
Scope a single policy to one or many Tunnels and Mesh nodes at once.

How it works

Granular permissions are a parallel layer to existing account-level roles — they do not replace them.

Existing account-level roles continue to work. A member with Cloudflare Access or Cloudflare Zero Trust retains write access to every Tunnel and Mesh node in the account. This ensures backward compatibility for existing automation and tokens.
Granular permissions are additive. For any API request on a specific Tunnel or Mesh node, access is granted if the principal has either the account-level role or a granular permission for that resource.
Resource enumeration is authorization-aware. Listing endpoints (GET /accounts/{id}/cfd_tunnel, GET /accounts/{id}/warp_connector) return only the resources the principal has at least read access to.

Get started

Configure granular permissions for Cloudflare Tunnel.
Configure granular permissions for Cloudflare Tunnel and Cloudflare Mesh in Cloudflare One.
Review the resource-scoped roles on the Cloudflare role reference.

Workers VPC - Reach Cloudflare WAN destinations from Workers VPC

Thu, 21 May 2026 00:00:00 GMT

You can now use VPC Network bindings with network_id: "cf1:network" to reach your full private network from Workers, including:

Cloudflare Mesh nodes and client devices
Subnet routes and hostname routes announced through Cloudflare Tunnel or Cloudflare Mesh
Destinations connected through Cloudflare WAN on-ramps — GRE, IPsec, and CNI

This means a single VPC Network binding can route Worker requests to private services regardless of how those services are connected to Cloudflare: through a Cloudflare Tunnel from a cloud VPC, a Mesh node on a private subnet, or a Cloudflare WAN on-ramp from your data center or branch site.

{
	"vpc_networks": [
		{
			"binding": "PRIVATE_NETWORK",
			"network_id": "cf1:network",
			"remote": true,
		},
	],
}

[[vpc_networks]]
binding = "PRIVATE_NETWORK"
network_id = "cf1:network"
remote = true

At runtime, the URL you pass to fetch() determines the destination:

// Reach a service behind a Cloudflare WAN IPsec on-ramp
const response = await env.PRIVATE_NETWORK.fetch("http://10.50.0.100:8080/api");

For configuration options, refer to VPC Networks.

DNS - New DNS records UX is rolling out

Wed, 20 May 2026 00:00:00 GMT

Starting today, everyone can opt in to a refreshed DNS records page in the Cloudflare dashboard. Over the coming weeks, the new experience will become the default for Free plan users first, followed by paid plans.

What is new

Better table experience: resizable and hideable columns, row pinning, advanced filters with logical operators (AND/OR), configurable pagination, and expanded input fields so long values are no longer cut off.
First-class mobile experience: responsive layout with a touch-friendly, card-based UI and compact controls for small screens.
DNS quick reference: bite-sized explainers for DNS, proxy status, and TTL, available directly in the product to help users configure records without leaving the page.
Modern frontend: a refactor onto Cloudflare's new UI framework that improves performance and lays the foundation for future improvements.

Rollout plan

Dates are subject to change based on feedback received during the rollout.

20 May - 05 June: ramped rollout to Free, then Pro and Business plans.
08 June - 03 July: ramped rollout to Enterprise plans.

Once the new experience is turned on for your account, look for the feedback link at the top of the DNS records page in the Cloudflare dashboard and let us know what you think. Your input helps us prioritize the next round of improvements.

Radar - Content type distribution and API traffic share on Cloudflare Radar

Wed, 20 May 2026 00:00:00 GMT

Radar now includes two new charts on the traffic page ↗ that provide deeper insights into the composition of HTTP traffic: a content type distribution chart and an API traffic share chart.

Content type distribution

The new Content type ↗ chart displays the distribution of HTTP response content types, grouped into high-level categories. A traffic type selector allows filtering by human, bot, or all traffic. The existing Bot vs. Human ↗ chart also gained a content type category filter, allowing users to see the bot/human split for specific content categories.

Content type categories:

HTML — Web pages (text/html)
Images — All image formats (image/*)
JSON — JSON data and API responses (application/json, *+json)
JavaScript — Scripts (application/javascript, text/javascript)
CSS — Stylesheets (text/css)
Plain Text — Unformatted text (text/plain)
Fonts — Web fonts (font/*, application/font-*)
XML — XML documents and feeds (text/xml, application/xml, application/rss+xml, application/atom+xml)
YAML — Configuration files (text/yaml, application/yaml)
Video — Video content and streaming (video/*, application/ogg, *mpegurl)
Audio — Audio content (audio/*)
Markdown — Markdown documents (text/markdown)
Documents — PDFs, Office documents, ePub, CSV (application/pdf, application/msword, text/csv)
Binary — Executables, archives, WebAssembly (application/octet-stream, application/zip, application/wasm)
Serialization — Binary API formats (application/protobuf, application/grpc, application/msgpack)
Other — All other content types

The CONTENT_TYPE dimension and contentType filter are available on the HTTP summary, timeseries groups, and timeseries endpoints.

The new API traffic ↗ chart shows the percentage of dynamic (non-cacheable) HTTP request traffic that is API-related. API traffic is identified by JSON or XML response content types (application/json, application/xml, text/xml) on HTTP requests that returned a 200 status code. A traffic type selector allows switching between human traffic, bot traffic, or all traffic.

The API_TRAFFIC dimension is available on the existing HTTP summary and timeseries groups endpoints. An apiTraffic filter (API or NON_API) can also be applied to HTTP timeseries requests to retrieve raw request counts for API-only or non-API traffic.

Visit the Radar traffic page ↗ to explore these new charts.

WAF - WAF Release - 2026-05-20

Wed, 20 May 2026 00:00:00 GMT

Key Findings

Existing rule enhancements have been deployed to improve detection resilience against broad classes of web attacks and strengthen behavioral coverage.

Continuous Rule Improvements

We are continuously refining our managed rules to provide more resilient protection and deeper insights into attack patterns. To ensure an optimal security posture, we recommend consistently monitoring the Security Events dashboard and adjusting rule actions as these enhancements are deployed.

Ruleset	Rule ID	Legacy Rule ID	Description	Previous Action	New Action	Comments
Cloudflare Managed Ruleset		N/A	Sitecore - Cache Poisoning - CVE:CVE-2025-53693 Beta	N/A	Block	This rule is merged into the original rule "Sitecore - Cache Poisoning - CVE:CVE-2025-53693" (ID: ).

Access - Cloudflare as identity provider and account membership selector

Tue, 19 May 2026 00:00:00 GMT

Cloudflare Access now supports using Cloudflare itself as an identity provider. If you publish an Access application and select Cloudflare as the login method, users can sign in with their existing Cloudflare account — no one-time PINs, no third-party IdP configuration, and no shared email inboxes. Authentication is backed by Cloudflare's own account security (including multi-factor authentication), making it both simpler to set up and more secure than OTP-based login for most use cases.

Cloudflare is now the default identity provider for all newly created Zero Trust accounts, replacing One-time PIN.

This also enables two new capabilities:

Cloudflare Account Member selector — A new policy selector that matches users based on their membership in a Cloudflare account. You can target the current account or specify a different account ID for cross-account access scenarios.
Restrict to account members — An identity provider configuration option that limits authentication to users who are members of your Cloudflare account.

To get started, add Cloudflare as an identity provider in your Zero Trust settings.

Artifacts, Queues - Event subscriptions for Artifacts lifecycle events

Tue, 19 May 2026 00:00:00 GMT

You can now receive event notifications for Artifacts repository changes and consume them from a Worker to build commit-driven automation.

This allows you to:

Run custom workflows when a repository is created or imported
Kick off a build and deploy a change when an agent pushes to a repo
Trigger a review agent on every push

Available events include:

Account-level events (artifacts source) — repo.created, repo.deleted, repo.forked, repo.imported
Repository-level events (artifacts.repo source) — pushed, cloned, fetched

To learn more, refer to Artifacts documentation.

CASB - CASB adds support for Claude Compliance API

Tue, 19 May 2026 00:00:00 GMT

Cloudflare CASB now integrates with the Claude Compliance API ↗. This enhancement gives security teams visibility into Claude usage patterns, admin activity, and compliance-relevant events across their organization.

The Claude Compliance API provides structured access to audit logs and administrative actions within Claude Enterprise and Claude Platform. Cloudflare CASB ingests this data to surface security findings that help organizations enhance their security posture and enforce AI governance.

Key capabilities

Starting today, security teams can scan for security findings across the following assets:

Public projects — Projects set to public visibility
Project attachment — Files and documents added to projects that violate DLP policies
Chat files — User-uploaded and provider-generated files that violate DLP policies
Chat messages — User prompts and provider responses that violate DLP policies
Artifacts — Provider-generated documents and files that violate DLP policies

Learn more

This integration is available to all Cloudflare One customers. New Cloudflare customers can sign up and start with their first two integrations for free. Existing customers can enable the integration directly in the dashboard. The integration begins scanning immediately and surfaces findings in the dashboard within minutes.

Radar - MRT Explorer on Cloudflare Radar

Tue, 19 May 2026 00:00:00 GMT

Radar now includes an MRT Explorer ↗ tool in the Routing section. Route collectors like RIPE RIS and RouteViews publish MRT (Multi-Threaded Routing Toolkit) dump files containing BGP announcements, withdrawals, and route attributes. The new tool parses these files entirely in the browser — nothing gets uploaded.

Loading a file

Paste a URL to fetch an MRT file remotely, drag and drop one onto the page, or browse for a local file. Gzip and bzip2 compressed files are supported. A sample file is also available to get started right away.

Inspecting events

Once parsed, the tool lists every BGP event with its timestamp, prefix, AS path, OTC (Only to Customer), and community attributes.

Event details

Clicking on the "View details" action opens a modal with additional properties and the full event JSON.

Shareable URLs

When loading a file by URL, the query string captures the source so the link can be shared directly — the recipient's browser immediately fetches and parses the same file.

Try the MRT Explorer on Cloudflare Radar ↗.

Artifacts - Manage Artifacts namespaces and repos with Wrangler CLI

Available commands:

wrangler artifacts namespaces list — List Artifacts namespaces in your account.
wrangler artifacts namespaces get — Get metadata for a namespace.
wrangler artifacts repos create — Create a repo in a namespace.
wrangler artifacts repos list — List repos in a namespace.
wrangler artifacts repos get — Get metadata for a repo.
wrangler artifacts repos delete — Delete a repo.
wrangler artifacts repos issue-token — Issue a repo-scoped token for Git access.

Cloudflare WAN, Magic Transit - Network Analytics support for Unified Routing

Mon, 18 May 2026 00:00:00 GMT

Network Analytics is now fully supported for accounts using Unified Routing mode. Traffic that traverses Unified Routing onramps and offramps is now visible in Network Analytics with the same dimensions and filters as traffic on the standard data plane.

This closes a parity gap for customers who had moved tunnels onto Unified Routing and lost visibility into their dataplane traffic in the Network Analytics dashboard. No configuration change is required — analytics data is collected automatically for all accounts with Unified Routing enabled.

For the remaining beta limitations, refer to Traffic steering beta limitations.

Workers - Share local dev servers through Cloudflare Tunnel in Wrangler and Vite

Mon, 18 May 2026 00:00:00 GMT

You can now share local dev sessions through Cloudflare Tunnel and get a public URL when using either Wrangler or the Cloudflare Vite plugin. This is useful when you need to share a preview, test a webhook, or access your app from another device.

This lets you either:

start a temporary Quick tunnel with a random *.trycloudflare.com hostname, or
use an existing named tunnel for a stable hostname and to restrict access with Cloudflare Access.

To start a tunnel, press t in Wrangler or t + Enter in Vite while your dev server is running. For details on setting up a named tunnel, refer to Share a local dev server.

Hyperdrive, Workers - Hyperdrive exposes database connection pool size metrics

Fri, 15 May 2026 00:00:00 GMT

You can now view the size of your Hyperdrive database connection pools, giving you the ability to self-diagnose connection issues. Using the Cloudflare dashboard or the hyperdrivePoolSizesAdaptiveGroups dataset in the GraphQL Analytics API, you can see waitingClients, currentPoolSize, availablePoolSlots, and maxPoolSize for each of your configurations.

A new Pool connections chart has been added to the Metrics tab of each Hyperdrive configuration in the Cloudflare dashboard ↗. You can use the location selector to drill down into specific locations hosting your connection pool by airport code.

The chart shows:

Waiting clients: Client requests waiting for an available connection.
Open connections: Active connections to your database.
Pool size maximum: Your configured origin connection limit.

Connection contention appears as a spike in waiting clients, or when open connections consistently approach the pool size maximum. If your open connections regularly approach this limit, consider contacting Cloudflare to increase your Hyperdrive connection limit.

Pool size metrics

The hyperdrivePoolSizesAdaptiveGroups dataset in the GraphQL Analytics API exposes the following key connection pool metrics for each Hyperdrive configuration:

Under avg:

currentPoolSize — Average number of connections currently open in the pool.
availablePoolSlots — Average number of pool connections available for checkout.
waitingClients — Average number of clients waiting for a connection from the pool.

Under max:

maxPoolSize — Configured maximum size of the connection pool.
currentPoolSize — Peak number of connections open in the pool.
waitingClients — Peak number of clients waiting for a connection from the pool.

For more information, refer to Metrics and analytics and Connection pooling.

R2 SQL - R2 SQL now supports JOINs, subqueries, and multi-table queries

Fri, 15 May 2026 00:00:00 GMT

R2 SQL is Cloudflare's serverless, distributed SQL engine for querying Apache Iceberg ↗ tables stored in R2 Data Catalog. R2 SQL runs directly on Cloudflare's global network with no infrastructure to manage, so you can analyze data in R2 without exporting it to an external warehouse.

R2 SQL now supports joining multiple Iceberg tables in a single query. You can combine tables with JOINs, filter with subqueries, and define multi-table CTEs to build complex analytical queries.

New capabilities

JOINs — INNER JOIN, LEFT JOIN, RIGHT JOIN, FULL OUTER JOIN, CROSS JOIN, and implicit joins (comma-separated FROM with conditions in WHERE)
Subqueries — IN / NOT IN, EXISTS / NOT EXISTS, scalar subqueries in SELECT / WHERE / HAVING, and derived tables (subqueries in FROM)
Multi-table CTEs — WITH clauses can reference different tables and include JOINs
Self-joins — join a table with itself using different aliases
Multi-way joins — join three or more tables in a single query

Examples

Two-table JOIN with aggregation

SELECT z.domain, z.plan, COUNT(*) AS request_count
FROM my_namespace.zones z
INNER JOIN my_namespace.http_requests h ON z.zone_id = h.zone_id
WHERE z.plan = 'enterprise'
GROUP BY z.domain, z.plan
ORDER BY request_count DESC
LIMIT 20

`EXISTS` subquery

SELECT z.domain, z.plan
FROM my_namespace.zones z
WHERE EXISTS (
    SELECT 1 FROM my_namespace.firewall_events f
    WHERE f.zone_id = z.zone_id AND f.action = 'block'
)
ORDER BY z.domain
LIMIT 20

Multi-table CTE with JOIN

WITH top_zones AS (
    SELECT zone_id, COUNT(*) AS req_count
    FROM my_namespace.http_requests
    GROUP BY zone_id
    ORDER BY req_count DESC
    LIMIT 50
),
zone_threats AS (
    SELECT zone_id, COUNT(*) AS threat_count
    FROM my_namespace.firewall_events
    WHERE risk_score > 0.5
    GROUP BY zone_id
)
SELECT tz.zone_id, tz.req_count, COALESCE(zt.threat_count, 0) AS threat_count
FROM top_zones tz
LEFT JOIN zone_threats zt ON tz.zone_id = zt.zone_id
ORDER BY tz.req_count DESC
LIMIT 20

WAF - WAF Release - 2026-05-15 - Emergency

Fri, 15 May 2026 00:00:00 GMT

This emergency release introduces two new rules to detect nginx heap buffer overflow and heap spray exploitation attempts targeting the rewrite module's is_args stale-state bug (CVE-2026-42945).

Key Findings

CVE-2026-42945: nginx Heap Buffer Overflow via Stale is_args in Rewrite Module

Successful exploitation allows remote attackers to trigger a heap buffer overflow in nginx's rewrite module by sending crafted URIs containing escapable characters. A length/copy pass mismatch in ngx_http_script_copy_capture_code() causes the copy pass to write escaped data into an undersized buffer, leading to heap corruption. This enables denial of service (worker process crash) and, with heap feng shui techniques, potential remote code execution.

We strongly recommend upgrading to nginx 1.30.1 (or later) immediately to address the underlying vulnerability. If you cannot upgrade immediately, avoid rewrite directives with ? in the replacement string followed by set or if referencing capture groups.

Ruleset	Rule ID	Legacy Rule ID	Description	Previous Action	New Action	Comments
Cloudflare Managed Ruleset		N/A	nginx - Remote Code Execution - Buffer Overread - CVE:CVE-2026-42945	N/A	Block	This is a new detection.
Cloudflare Managed Ruleset		N/A	nginx - Remote Code Execution - Heap Spray - CVE:CVE-2026-42945	N/A	Block	This is a new detection.

Workers - New Domains tab in the Workers dashboard

Thu, 14 May 2026 00:00:00 GMT

In your Worker's dashboard, there is now a dedicated Domains tab where you can purchase a new domain through Cloudflare Registrar and have it automatically connected, add an existing domain, and manage all of your Worker's routing in one place.

You can also enable or disable your workers.dev subdomain and Preview URLs, put them behind Cloudflare Access to require sign-in, and jump directly to analytics or domain overview for any connected domain.

To get started, go to Workers & Pages, select a Worker, and open the Domains tab.

Agents, Workers - Agents SDK v0.12.4: chat recovery, routing retries, durable Think submissions, and Voice connection control

Wed, 13 May 2026 00:00:00 GMT

The latest release of the Agents SDK ↗ brings more reliable chat recovery, fixes Agent state synchronization during reconnects, adds durable submissions for Think, exposes routing retry configuration, and adds connection control for Voice agents.

Chat recovery improvements

@cloudflare/ai-chat now keeps server turns running when a browser or client stream is interrupted. This is useful for long-running AI responses where users refresh the page, close a tab, or temporarily lose connection. Calling stop() still cancels the server turn.

Set cancelOnClientAbort: true if browser or client aborts should also cancel the server turn:

const chat = useAgentChat({
	agent: "assistant",
	name: "user-123",
	cancelOnClientAbort: true,
});

const chat = useAgentChat({
	agent: "assistant",
	name: "user-123",
	cancelOnClientAbort: true,
});

Notable bug fixes:

Chat stream resume negotiation no longer throws when replay races with a closed WebSocket connection.
Recovered chat continuations no longer leave useAgentChat stuck in a streaming state when the original socket disconnects before a terminal response.
Approval auto-continuation preserves reasoning parts and persists continuation reasoning in the final message.
isServerStreaming now resets correctly when a resumed stream moves from the fallback observer path to a transport-owned stream.

Agent state and routing fixes

agents@0.12.4 prevents duplicate initial state frames during WebSocket connection setup. This avoids stale initial state messages overwriting state updates already sent by the client.

Agent recovery is also more reliable when tool calls span a Durable Object restart. Recovery now defers user finish hooks until after agent startup and isolates hook failures, so one failed hook does not block other recovered runs from finalizing.

getAgentByName() now supports routingRetry for transient Durable Object routing failures:

import { getAgentByName } from "agents";

const agent = await getAgentByName(env.AssistantAgent, "user-123", {
	routingRetry: {
		maxAttempts: 3,
	},
});

import { getAgentByName } from "agents";

const agent = await getAgentByName(env.AssistantAgent, "user-123", {
	routingRetry: {
		maxAttempts: 3,
	},
});

Durable Think submissions

@cloudflare/think now supports durable programmatic submissions. submitMessages() provides durable acceptance, idempotent retries, status inspection, cancellation, and cleanup for server-driven turns that should continue after the caller returns.

Think.chat() RPC turns now run inside chat recovery fibers and persist their stream chunks. Interrupted sub-agent turns can recover partial output instead of starting over.

ChatOptions.tools has been removed from the TypeScript API. Define durable tools on the child agent or use agent tools for orchestration. Runtime options.tools values passed by legacy callers are ignored with a warning.

Think message pruning behavior change

@cloudflare/think no longer applies pruneMessages({ toolCalls: "before-last-2-messages" }) to model context by default. The previous default could strip client-side tool results from longer multi-turn flows.

truncateOlderMessages still runs as before, so context cost remains bounded. Subclasses that relied on the old aggressive pruning can opt back in from beforeTurn:

import { Think } from "@cloudflare/think";
import { pruneMessages } from "ai";

export class MyAgent extends Think {
	beforeTurn(ctx) {
		return {
			messages: pruneMessages({
				messages: ctx.messages,
				toolCalls: "before-last-2-messages",
			}),
		};
	}
}

import { Think } from "@cloudflare/think";
import { pruneMessages } from "ai";

export class MyAgent extends Think<Env> {
	beforeTurn(ctx) {
		return {
			messages: pruneMessages({
				messages: ctx.messages,
				toolCalls: "before-last-2-messages",
			}),
		};
	}
}

Voice agent connection control

@cloudflare/voice adds an enabled option to useVoiceAgent. React apps can now delay creating and connecting a VoiceClient until prerequisites such as capability tokens are ready.

const voice = useVoiceAgent({
	agent: "MyVoiceAgent",
	enabled: Boolean(token),
});

const voice = useVoiceAgent({
	agent: "MyVoiceAgent",
	enabled: Boolean(token),
});

This release also fixes Workers AI speech-to-text session edge cases and withVoice text streaming from AI SDK textStream responses.

Other improvements

Streamable HTTP routing — Server-to-client requests now route through the originating POST stream when no standalone SSE stream is available.
Structured tool output — Tool output shapes are preserved when truncating older messages or oversized persisted rows.
Non-chat Think tool steps — Think agent-tool children can complete without emitting assistant text and can return structured output through getAgentToolOutput.
Sub-agent schedules — Stale sub-agent schedule rows are pruned when their owning facet registry entry no longer exists.
@cloudflare/codemode — Adds a browser-safe export with an iframe sandbox executor and resolves OpenAPI specs inside the sandbox to avoid Worker Loader RPC size limits.

Upgrade

To update to the latest version:

npm i agents@latest @cloudflare/ai-chat@latest @cloudflare/think@latest @cloudflare/voice@latest

Refer to the Agents API reference and Chat agents documentation for more information.

Logs - New Logpush datasets and updated fields across multiple Logpush datasets in Cloudflare Logs

Wed, 13 May 2026 00:00:00 GMT

Cloudflare has updated Logpush datasets:

New datasets

Email Security Post-Delivery Events: A new dataset with fields including AlertID, CompletedAt, Destination, FinalDisposition, Folder, From, FromName, MessageID, MessageTimestamp, MicrosoftTenantID, Operation, PostfixID, Reasons, Recipient, RequestedAt, RequestedBy, RequestedDisposition, Status, Subject, Success, and To.
Magic Network Monitoring Flow Logs: A new dataset with fields including AWSVPCFlowJSON, Bits, DestinationAS, DestinationAddress, DestinationPort, DeviceID, EgressBits, EgressPackets, Ethertype, FlowProtocol, FlowTimestamp, NumFlows, PacketID, Packets, Protocol, RuleIDs, SampleRate, SampleRateType, SamplerAddress, SourceAS, SourceAddress, SourcePort, TcpFlags, and Timestamp.

Updated fields in existing datasets

Firewall events (added): AISecurityInjectionScore, AISecurityPIICategories, AISecurityTokenCount, and AISecurityUnsafeTopicCategories.
HTTP requests (added): AISecurityInjectionScore, AISecurityPIICategories, AISecurityTokenCount, AISecurityUnsafeTopicCategories, and Subrequests.

For the complete field definitions for each dataset, refer to Logpush datasets.

Cloudflare Web Analytics - /cdn-cgi/rum endpoint now returns 405 for non-POST requests

Wed, 13 May 2026 00:00:00 GMT

The /cdn-cgi/rum beacon endpoint now returns 405 Method Not Allowed for non-POST requests instead of 404 Not Found. The response includes an Allow: POST, OPTIONS header per RFC 9110 §15.5.6 ↗.

Previously, sending a GET or other non-POST request to this endpoint returned a 404, which was misleading because it suggested the endpoint did not exist. The new 405 response clearly indicates that the endpoint exists but only accepts POST requests.

The Web Analytics beacon (beacon.min.js) already uses POST for all metric submissions, so this change does not affect normal beacon operation. OPTIONS requests for CORS preflight continue to work as before.

For more information, refer to the Web Analytics FAQ.

Cloudflare One, Access - Refreshed Access login page

Tue, 12 May 2026 00:00:00 GMT

The Access login page and one-time password (OTP) page now feature a refreshed design that improves visual consistency, user trust, and mobile responsiveness.

Before:

After:

The updated login experience includes:

Unified authentication card - All sign-in options (identity provider buttons, email input, OTP) now appear in a single card with consistent styling, replacing the previous multi-section layout.
Consistent button styling - Identity provider buttons use a uniform size and layout for easier scanning and selection.
Better mobile experience - Responsive layout improvements ensure the login page renders correctly on phones and tablets.
Dark mode support - The login page now supports dark mode.

Cloudflare WAN, Magic Transit, Cloudflare One - New accounts assigned a single IPv4 anycast address

Tue, 12 May 2026 00:00:00 GMT

New Magic Transit and Cloudflare WAN accounts are now assigned a single IPv4 anycast address by default.

Cloudflare handles failures on its network automatically by advertising your endpoint IP from multiple nodes across many globally distributed data centers. To handle failures on your network, configure two tunnels from separate routers.

To request additional anycast IP addresses for your account, contact your account team.

For tunnel configuration guidance, refer to Configure tunnel endpoints for Cloudflare WAN or Configure tunnel endpoints for Magic Transit.

Containers - SSH through Wrangler is now enabled by default for Containers

Tue, 12 May 2026 00:00:00 GMT

SSH through Wrangler is now enabled by default for Containers. Previously, you had to set ssh.enabled to true in your Container configuration before you could connect.

This change does not expose any publicly accessible ports on your Container. The SSH service is reachable only through wrangler containers ssh, which authenticates against your Cloudflare account. You also need to add an ssh-ed25519 public key to authorized_keys before anyone can connect, so enabling SSH alone does not grant access.

To connect, add a public key to your Container configuration and run wrangler containers ssh <INSTANCE_ID>:

{
	"containers": [
		{
			"authorized_keys": [
				{
					"name": "<NAME>",
					"public_key": "<YOUR_PUBLIC_KEY_HERE>",
				},
			],
		},
	],
}

[[containers]]
[[containers.authorized_keys]]
name = "<NAME>"
public_key = "<YOUR_PUBLIC_KEY_HERE>"

To disable SSH, set ssh.enabled to false in your Container configuration:

{
	"containers": [
		{
			"ssh": {
				"enabled": false,
			},
		},
	],
}

[[containers]]
[containers.ssh]
enabled = false

For more information, refer to the SSH documentation.

Gateway - Create Gateway firewall policies with natural language

Tue, 12 May 2026 00:00:00 GMT

Cloudflare Gateway now supports natural language policy creation for DNS, HTTP, and Network firewall policies. Administrators can describe the outcome they want in plain language, and Cloudflare will generate a complete policy rule that populates the policy builder form.

To create a policy with natural language, select Create with AI on any Gateway firewall policy tab. Choose a policy type, describe what the policy should do, and a fully configured rule will appear in the policy builder for review. You can edit any field before saving, or re-generate with a different prompt.

The generated policy incorporates your account context - including lists, DLP profiles, applications, and device posture checks - so that references to your existing resources resolve automatically.

A built-in feedback mechanism allows you to rate each generated policy and provide optional comments, which Cloudflare uses to improve output quality over time.

For more information, refer to Gateway firewall policies.

R2, R2 Data Catalog - R2 Data Catalog now exposes metrics via the GraphQL Analytics API

Tue, 12 May 2026 00:00:00 GMT

R2 Data Catalog is a managed Apache Iceberg data catalog built directly into your R2 bucket that allows you to connect query engines like R2 SQL, Spark, Snowflake, and DuckDB to your data in R2.

You can now query analytics for your R2 Data Catalog warehouses via Cloudflare's GraphQL Analytics API. Two new datasets are available:

r2CatalogDataOperationsAdaptiveGroups tracks Iceberg REST API requests made to your catalog, including operation type, request duration, HTTP status, and request body bytes. Use this to monitor request volume and latency across warehouses, namespaces, and tables.
r2CatalogTableMaintenanceAdaptiveGroups tracks table maintenance jobs such as compaction and snapshot expiration. Use this to monitor job success rates, files processed, bytes read and written, and job duration.

Both datasets support filtering by warehouse name, namespace, table name, and time range. They also include percentile aggregations for duration metrics.

For detailed schema information and example queries, refer to the R2 Data Catalog metrics and analytics documentation.

Security Center - Agent Readiness scores now available in URL Scanner via the Cloudflare Dashboard

Tue, 12 May 2026 00:00:00 GMT

We’ve added a new Agent Readiness tab to URL Scanner reports accessible via the Cloudflare dashboard. This feature evaluates your site against emerging AI standards and provides six specialized scores to help you optimize for the next generation of AI agents and automated discovery.

The Internet is shifting from a human-read web to a machine-read web. AI agents now browse, interact with, and even perform transactions on websites. If a site isn't "agent-ready," these bots may consume excessive bandwidth, fail to find critical information, or be unable to navigate your services efficiently.

This update provides material value by breaking down readiness into six actionable categories:

Basic Web Presence
Discoverability
Content Accessibility
Bot Access Control
Protocol Discovery
Commerce

Accessing the report

You can view these scores for any scanned URL directly in the dashboard or via our API.

Dashboard: Go to Protect & Connect > Application Security > Investigate. After running a scan, select the Agent Readiness tab in the report.
API: Use the URL Scanner API ↗ to programmatically retrieve these scores for your infrastructure.

To learn more about the methodology behind these scores, refer to the blogpost ↗.

Cloudflare One Client - Cloudflare One Client for Windows (version 2026.4.1350.0)

Mon, 11 May 2026 17:35:58 GMT

A new GA release for the Windows Cloudflare One Client is now available on the stable releases downloads page.

Right click context menu to access the most common client actions quickly
Built-in captive portal login experience

Additional Changes and improvements

Added a new CLI command: warp-cli mdm refresh. This command executes an immediate refresh of the Mobile Device Management (MDM) configuration file.

Known issues

Registration authentication for devices via the integrated WebView2 browser is unavailable in this version as a temporary measure. As a result, the client will utilize the default browser on the device to complete the authentication process.
An error indicating that Microsoft Edge can't read and write to its data directory may be displayed during captive portal login; this error is benign and can be dismissed.
Registration may hang at "Checking your organization configuration" due to IPC errors. A system reboot should resolve the error, allowing registration to proceed.
Split tunnel list configuration is not available in the new UI. Management of Split Tunnel entries is currently only possible via warp-cli tunnel ip and warp-cli tunnel host. UI support will be added in a future release.
Windows ARM may prompt the user to close running applications while trying to install this version. Simply click “Ok” with the default highlighted option.
DNS resolution may be broken when the following conditions are all true:
- The client is in Secure Web Gateway without DNS filtering (tunnel-only) mode.
- A custom DNS server address is configured on the primary network adapter.
- The custom DNS server address on the primary network adapter is changed while the client is connected.
  To work around this issue, please reconnect the client by selecting "disconnect" and then "connect" in the client user interface.

Changes and improvements

Added a new CLI command: warp-cli mdm refresh. This command executes an immediate refresh of the Mobile Device Management (MDM) configuration file.
Official support for RHEL 9 has been added for Cloudflare Mesh nodes. To install the RHEL 9 package, the Extra Packages for Enterprise Linux (EPEL) repository must be active, as it contains dependencies required for the tray icon and captive portal webview.

Known issues

Registration may hang at "Checking your organization configuration" due to IPC errors. A system reboot should resolve the error, allowing registration to proceed.
Split tunnel list configuration is not available in the new UI. Management of split tunnel entries is currently only possible via warp-cli tunnel ip and warp-cli tunnel host. UI support will be added in a future release.

Cloudflare WAN, Magic Transit - NAT-T support for IKE on UDP port 500

Mon, 11 May 2026 00:00:00 GMT

Cloudflare IPsec now supports the standard NAT traversal (NAT-T) flow, where IKE begins on UDP port 500 and switches to UDP port 4500 after NAT is detected.

Previously, devices behind NAT had to be configured to initiate IKE on UDP port 4500 directly. Devices that started on UDP port 500 could not complete the IKE handshake when NAT was in the path. This required custom configuration on devices such as VeloCloud SD-WAN edges, Cisco IOS-XE routers, and Juniper SRX firewalls, and was not possible on every platform.

What changed:

Devices behind NAT can now initiate IKE on either UDP port 500 or UDP port 4500.
Devices that start IKE on UDP port 500 and switch to UDP port 4500 after NAT detection now complete the handshake successfully.
No configuration change is required on Cloudflare. The change is available for all IPsec tunnels on Cloudflare WAN and Magic Transit.

This change does not affect existing tunnels:

Tunnels using UDP port 500 with no NAT detected continue to operate as before.
Tunnels configured to start IKE on UDP port 4500 continue to operate as before.
NAT detection logic is unchanged.

For configuration details, refer to GRE and IPsec tunnels.

Workers, WAF - WAF and framework adapter mitigations for React and Next.js vulnerabilities

Thu, 07 May 2026 12:00:00 GMT

Multiple security vulnerabilities were disclosed by the React team and Vercel affecting React Server Components and Next.js. These include denial of service, middleware and proxy bypass, server-side request forgery, cross-site scripting, and cache poisoning issues across a range of severity levels.

We strongly recommend updating your application and its dependencies immediately. Patched versions are available for React (react-server-dom-webpack, react-server-dom-parcel, and react-server-dom-turbopack 19.0.6, 19.1.7, and 19.2.6) and Next.js (15.5.16 and 16.2.5).

WAF protections

Cloudflare WAF rules deployed in response to prior React Server Component CVEs (CVE-2025-55184 ↗ and CVE-2026-23864 ↗) already provide coverage for the newly disclosed denial-of-service vulnerabilities. These rules are enabled by default with a Block action for all customers using the Cloudflare Managed Ruleset, including Free plan customers using the Free Managed Ruleset.

Ruleset	Rule description	Rule ID	Default action
Cloudflare Managed Ruleset	React - DoS - `CVE-2025-55184` ↗	`2694f1610c0b471393b21aef102ec699`	Block
Cloudflare Managed Ruleset	React - DoS - `CVE-2026-23864` ↗	`aaede80b4d414dc89c443cea61680354`	Block

The existing rules detect the underlying attack patterns generically. As a result, they apply to the new CVE-2026-23870 ↗ denial-of-service vulnerability in Server Components and the corresponding Next.js advisory GHSA-8h8q-6873-q5fj ↗.

Cloudflare is investigating whether WAF rules can be safely and effectively deployed for three of the high-severity advisories: CVE-2026-23870 ↗ / GHSA-8h8q-6873-q5fj ↗, GHSA-267c-6grr-h53f ↗, and GHSA-mg66-mrh9-m8jx ↗. If it is possible to create a managed WAF rule that mitigates these CVEs and does not potentially break application behavior, Cloudflare will add additional managed WAF rules. These rules will be announced through the WAF changelog. Because these vulnerabilities were shared with Cloudflare with minimal advance notice, we are still investigating what WAF mitigations are possible.

Several of the disclosed vulnerabilities are not possible to block in WAF. We strongly recommend updating your applications so they are not purely reliant on WAF mitigations.

Customers on Pro, Business, or Enterprise plans should ensure that Managed Rules are enabled.

Next.js adapters

Vinext: Vinext ↗ is a Vite plugin that reimplements the Next.js API surface. Vinext's latest release is not vulnerable to any of the disclosed CVEs. Vinext's architecture differs from stock Next.js in ways that sidestep the affected code paths. For example, it does not implement the PPR resume protocol, does not expose Pages Router data-route endpoints, and strips internal headers such as x-nextjs-data at request boundaries. As an extra layer of defense, we added a React 19.2.6 or later requirement when running vinext init (PR #1118 ↗, PR #1112 ↗) to prevent accidentally running a vulnerable version of React with Vinext.

OpenNext on Cloudflare: OpenNext is an adapter that lets you deploy Next.js apps to the Cloudflare Workers platform. OpenNext itself is not directly vulnerable to the React denial-of-service CVE, but users must update the Next.js version in their application. The OpenNext team has updated the adapter to further harden against these vectors and released a new version of the Cloudflare adapter. Test fixtures and examples have been updated to use patched versions (PR #1255 ↗).

Cloudflare One Appliance, Cloudflare One, Cloudflare WAN - Custom DHCP options on Cloudflare One Appliance

Thu, 07 May 2026 00:00:00 GMT

When the Cloudflare One Appliance is acting as the DHCP server for a LAN, you can now configure custom DHCP options on the leases it issues. This unlocks workflows such as PXE / iPXE boot, VoIP phone provisioning, and vendor-specific client configuration.

Each option is defined by option_number, value, and one of four value types: text, integer, hex, or ip. Configurations are validated on the appliance before being applied — invalid configurations are rejected and the underlying error is returned to the API caller, so a bad option will not disrupt the live DHCP service.

For details, refer to DHCP server options.

Cloudflare One Appliance, Cloudflare One, Cloudflare WAN - Source-based breakout and prioritization on Cloudflare One Appliance

Thu, 07 May 2026 00:00:00 GMT

Breakout and traffic prioritization rules on the Cloudflare One Appliance can now match by source in addition to destination application. You can pin breakout or priority behavior to:

A source LAN interface — VLANs attached to that LAN are included automatically.
A source IP address, range, or CIDR block.

This is the natural way to break out a guest VLAN to the local Internet, or to prioritize traffic from a specific subnet, without enumerating destination applications.

For details, refer to Breakout traffic.

Cloudflare One Appliance, Cloudflare One, Cloudflare WAN - Self-serve provisioning of Cloudflare One Virtual Appliance via API

Thu, 07 May 2026 00:00:00 GMT

You can now create, rotate, and delete Cloudflare One Virtual Appliance instances and their license keys directly via the API and Terraform.

Create a virtual appliance and receive a license key: POST /accounts/{account_id}/magic/connectors with device.provision_license: true.
Rotate the license key for an existing virtual appliance: PATCH /accounts/{account_id}/magic/connectors/{connector_id} with provision_license: true. The previous key is immediately and irrevocably revoked.
Delete a virtual appliance to release the associated licensed device.

The license key is returned in the response only once, at create or rotate time. Copy and store it securely.

For details, refer to Configure a Cloudflare One Virtual Appliance.

Security Center - CSV export and adjustable page density for RFIs

Thu, 07 May 2026 00:00:00 GMT

You can now export your Requests for Information (RFI) history to a CSV document and customize your dashboard view by choosing how many RFI records to load per page.

Why this matters

These quality-of-life updates focus on data portability and dashboard performance, allowing power users to manage high volumes of requests more efficiently:

The new CSV export allows you to move RFI data into external tools for custom reporting, internal auditing, or cross-referencing with other security projects without manual data entry
With adjustable page density, you can now choose to load more records at once (10, 25 or 50) to scan through history faster

Cloudforce One subscribers can find these new options in Cloudflare Dashboard > Application Security > Threat Intelligence > Requests for Information ↗.

Stream - Introducing Stream Bindings for Workers

Thu, 07 May 2026 00:00:00 GMT

You can now interact with your Stream video library using new bindings for Workers! This allows customers to upload content to Stream, provision direct uploads, manage videos, and generate signed URLs from a Worker without making authenticated API calls. We're excited to bring Stream and Workers closer together to empower more programmatic pipelines, tighter integrations, and support generative AI and inference workloads.

Use the Stream binding when you want to:

Upload videos from URLs or create basic direct upload links for end users
Generate signed playback tokens without managing signing keys
Manage video metadata, captions, downloads, and watermarks
Build video pipelines entirely within Workers

To get started, add the Stream binding to your Wrangler configuration:

{
  "$schema": "./node_modules/wrangler/config-schema.json",
  "stream": {
    "binding": "STREAM"
  }
}

[stream]
binding = "STREAM"

Generate a video with AI and upload directly to Stream or send a URL of a file you already have:

const aiResponse = await env.AI.run(
	"google/veo-3.1",
	{
		prompt: "A dog walking next to a river",
		duration: "10s",
		aspect_ratio: "16:9",
		resolution: "1080p",
		generate_audio: true,
	},
	{
		gateway: { id: "experiments" },
	},
);

// Veo will return a URL of the generated asset.
const videoUrl = aiResponse.result.video;

// Alternative option: a video of the Austin Office mobile
// const videoUrl = 'https://pub-d9fcbc1abcd244c1821f38b99017347f.r2.dev/aus-mobile.mp4';

// Upload to Stream by providing a URL
const streamVideo = await env.STREAM.upload(videoUrl);

// The streamVideo response will include the video ID, playback and manifest
// URLs, and other information, just like the REST API.

const aiResponse = await env.AI.run(
	'google/veo-3.1',
	{
		prompt: 'A dog walking next to a river',
		duration: '10s',
		aspect_ratio: '16:9',
		resolution: '1080p',
		generate_audio: true,
	},
	{
		gateway: { id: 'experiments' },
	},
);

// Veo will return a URL of the generated asset.
const videoUrl = aiResponse.result.video;

// Alternative option: a video of the Austin Office mobile
// const videoUrl = 'https://pub-d9fcbc1abcd244c1821f38b99017347f.r2.dev/aus-mobile.mp4';

// Upload to Stream by providing a URL
const streamVideo = await env.STREAM.upload(videoUrl);

// The streamVideo response will include the video ID, playback and manifest
// URLs, and other information, just like the REST API.

Generate a signed URL without using a signing key or an API call:

const video_id = "ce800be43a9772f4bb02f35b860fb516";
const token = await env.STREAM.video(video_id).generateToken();

// Use the "token" in an iframe embed code, manifest URL, or thumbnail:
const embedUrl = `https://customer-igynxd2rwhmuoxw8.cloudflarestream.com/${token}/iframe`;

const video_id = 'ce800be43a9772f4bb02f35b860fb516';
const token = await env.STREAM.video(video_id).generateToken();

// Use the "token" in an iframe embed code, manifest URL, or thumbnail:
const embedUrl = `https://customer-igynxd2rwhmuoxw8.cloudflarestream.com/${token}/iframe`;

Get and set video properties easily:

const video_id = "46c8b7f480d410840758c1cb14a72e47";
const result = await env.STREAM.video(video_id).details();

await env.STREAM.video(video_id).update({
	meta: { name: "sample video" },
});

const video_id = '46c8b7f480d410840758c1cb14a72e47';
const result = await env.STREAM.video(video_id).details();

await env.STREAM.video(video_id).update({
  meta: { name: 'sample video' }
});

For setup instructions and the full API reference, refer to Bind to Workers API.

Get started with your Agent

Add a binding for Cloudflare Stream (env.STREAM). On the watch page, use the Stream binding to get info based on the ID, and leverage video.meta.name as the page title.

WAF - WAF Release - 2026-05-07 - Emergency

Thu, 07 May 2026 00:00:00 GMT

This emergency release introduces a new rule to detect Next.js App Router middleware and proxy bypass attempts via segment-prefetch routes (CVE-2026-44575).

Key Findings

CVE-2026-44575: Next.js Middleware / Proxy Bypass in App Router Applications via Segment-Prefetch Routes

Successful exploitation allows unauthenticated attackers to bypass middleware or proxy-based authorization checks in affected Next.js App Router applications. This leads to unauthorized access to protected content, potential exposure of sensitive application data, and compromise of application security boundaries.

We strongly recommend upgrading to Next.js 15.5.16 or 16.2.5 (or later) immediately to address the underlying vulnerability. If you cannot upgrade immediately, enforce authorization in the underlying route or page logic instead of relying solely on middleware.

Ruleset	Rule ID	Legacy Rule ID	Description	Previous Action	New Action	Comments
Cloudflare Managed Ruleset		N/A	Next.js - Middleware Bypass via Invalid RSC Header - CVE:CVE-2026-44575	N/A	Disabled	This is a new detection.

Workers - Automatic tracing across Durable Object and Worker subrequests

Thu, 07 May 2026 00:00:00 GMT

You can now get a single unified trace across Worker-to-Worker subrequests, with trace context propagating automatically. Previously, automatic tracing produced disconnected traces when a Worker called another Worker through a service binding or Durable Object.

This means you can:

Follow a request through your entire Worker architecture in one trace view
See service binding and Durable Object calls as nested child spans instead of separate traces
Debug cross-Worker request flows in the Cloudflare dashboard or in an external observability platform via OpenTelemetry

Tracing must be enabled in your Wrangler configuration for traces to be recorded. Checkout Workers tracing to get started.

Up next, we are working on external trace context propagation using W3C Trace Context standards ↗, which will allow traces from your Workers to link with traces from services outside of Cloudflare.

Email security - Cloudy Summaries in PhishNet O365

Wed, 06 May 2026 18:15:13 GMT

PhishNet users can now access Cloudy summaries directly within the email investigation experience. When reviewing a message in PhishNet, users will see an AI-generated summary that provides additional context and key details about the email.

These summaries help users quickly understand the nature of a message without needing to manually parse through headers, body content, and detection signals. Cloudy surfaces the most relevant information so users can make faster, more informed decisions about suspicious emails.

These summaries are not trained on customer data. They are generated using the outputs of our existing detection models and analysis systems.

This feature is available for PhishNet with Office 365. Support for Gmail will be available by the end of the quarter.

Cloudflare One - IPv6 CIDR routes for Cloudflare Mesh

Wed, 06 May 2026 00:00:00 GMT

Cloudflare Mesh nodes now support IPv6 CIDR routes. You can advertise both IPv4 and IPv6 subnets through your Mesh nodes, making IPv6-only or dual-stack private networks reachable from any enrolled device.

To add an IPv6 route, follow the same steps as adding an IPv4 route — enter the IPv6 CIDR (for example, fd00::/64) when configuring the route in the dashboard ↗ or via the API.

Radar - TLD Nameserver Performance in Cloudflare Radar

Wed, 06 May 2026 00:00:00 GMT

Radar now provides TLD authoritative nameserver performance insights, measuring response time (latency) as observed from Cloudflare's 1.1.1.1 resolver infrastructure when forwarding queries upstream to TLD nameservers.

New widgets on TLD detail pages ↗:

Aggregate nameserver latency ↗: Response time percentiles (p25/p50/p75) for all authoritative nameservers of the selected TLD.
Latency per nameserver ↗: Median response time (p50) broken down by each authoritative nameserver over time.

Median latency geographic distribution ↗: p50 response time by Cloudflare data center country, displayed on a choropleth map.
TLD ranking over time ↗: Daily DNS magnitude rank and magnitude value with a Rank/Magnitude toggle.
Rank change deltas ↗: 1 week, 4 weeks, and 3 months rank changes added to the TLD magnitude table and the TLD detail info panel.

The new TLD Performance API provides the following endpoints:

/tlds/performance/summary/{dimension} — TLD nameserver performance summarized by dimension.
/tlds/performance/timeseries_groups/{dimension} — TLD nameserver performance over time grouped by dimension.

Available dimensions: LATENCY (aggregate p25/p50/p75), NAMESERVER_LATENCY (per-nameserver p50), LOCATION_LATENCY (per-data-center-country p50).

TLD Performance is also available as a dataset in the Data Explorer ↗.

Check out the updated TLD detail page ↗.

Security Center - TAXII support added to Threat Events API

Wed, 06 May 2026 00:00:00 GMT

The Cloudforce One Threat Events API now supports TAXII ↗ as an output format, enabling standardized, automated sharing of cyber threat intelligence with your existing security stack.

Why this matters

You can now ingest Cloudforce One threat data directly into your SIEM, TIP or SOAR tools that prefer TAXII-formatted streams without needing custom translation scripts.
By supporting the TAXII format parameter in our API, security teams can automate the synchronization of indicator data, reducing the manual overhead of updating blocklists and detection rules.
This alignment with industry standards ensures that your threat data remains consistent across different security ecosystems and partner integrations.

How to use it

When calling the Threat Events API, you can now specify taxii in the format query parameter:

GET /accounts/{account_id}/cloudforce_one/threat_events?format=taxii

You can find the updated documentation in the Cloudflare API Reference ↗.

Cache - Pingora now powers Cloudflare's cache

Mon, 04 May 2026 00:00:00 GMT

Cloudflare's cache now runs on a new proxy built on Pingora ↗, the Rust-based framework that already serves a significant portion of Cloudflare's network traffic. The new proxy is faster, more memory-safe, and designed to evolve our cache architecture. It delivers immediate performance improvements and enables new caching capabilities.

What this brings

Lower latency: The new proxy reduces per-request overhead through improved connection reuse.
Reduced cache MISSes: Enhanced cache retention improves origin offload.
Better RFC compliance: Caching behavior more closely follows HTTP caching standards.
Foundation for future features: The new architecture enables upcoming improvements to cache functionality and efficiency.

New features

Asynchronous stale-while-revalidate: Every request returns stale content immediately while revalidation happens in the background, instead of the first request after expiry blocking on the origin. Refer to the asynchronous stale-while-revalidate changelog for details.
Unbuffered bypass by default: Responses that bypass cache are streamed directly to the client without buffering, reducing time-to-first-byte for uncacheable content.

Behavioral changes

The new architecture introduces the following behavioral changes to improve RFC compliance and correctness:

Vary: * results in cache bypass: According to RFC 9110 Section 12.5.5 ↗, a Vary header value of * indicates the response varies on factors beyond request headers and must not be served from cache. Cloudflare now bypasses cache for these responses instead of storing them.
Set-Cookie stripped on MISS and EXPIRED: For cacheable assets, Set-Cookie is now stripped on MISS and EXPIRED responses, not only on HITs.
Floating-point TTL values: Floating-point time-to-live values (for example, max-age=1.5) are rounded down to the nearest integer instead of being rejected as invalid.

What's next

A deeper look at the new cache proxy is coming soon to the Cloudflare blog ↗. For background on the underlying framework, read:

Pipelines - Pipelines and R2 Data Catalog now supported in Terraform

Mon, 04 May 2026 00:00:00 GMT

Cloudflare Pipelines ingests streaming data via Workers or HTTP endpoints, transforms it with SQL, and writes it to R2 as Apache Iceberg tables. R2 Data Catalog manages those Iceberg tables, compaction, and compatibility with query engines like R2 SQL, Spark, and DuckDB.

You can now create and manage both products using Terraform, supported in the Cloudflare Terraform provider v5.19.0 ↗.

This adds four new resources that let you define your entire data pipeline as infrastructure-as-code: a data catalog, a stream for ingestion, a sink that writes to R2 Data Catalog or R2, and a pipeline that connects them with SQL.

The new Terraform resources are:

cloudflare_r2_data_catalog ↗ — enable the data catalog on an R2 bucket
cloudflare_pipeline_stream ↗ — create a stream that receives events via HTTP or Worker bindings
cloudflare_pipeline_sink ↗ — create a sink that writes to R2 Data Catalog or R2
cloudflare_pipeline ↗ — create a pipeline with SQL connecting a stream to a sink

Here is a minimal example that creates a stream, an R2 Data Catalog sink, and a pipeline:

resource "cloudflare_pipeline_stream" "my_stream" {
  account_id = var.cloudflare_account_id
  name       = "my_stream"
  format     = { type = "json" }
  schema = {
    fields = [{
      name     = "value"
      type     = "json"
      required = true
    }]
  }
  http           = { enabled = true, authentication = false, cors = {} }
  worker_binding = { enabled = false }
}

resource "cloudflare_pipeline_sink" "my_sink" {
  account_id = var.cloudflare_account_id
  name       = "my_sink"
  type       = "r2_data_catalog"
  format     = { type = "parquet" }
  schema     = { fields = [] }
  config = {
    account_id = var.cloudflare_account_id
    bucket     = "my-pipeline-bucket"
    table_name = "my_table"
    token      = var.catalog_token
  }
}

resource "cloudflare_pipeline" "my_pipeline" {
  account_id = var.cloudflare_account_id
  name       = "my_pipeline"
  sql        = "INSERT INTO ${cloudflare_pipeline_sink.my_sink.name} SELECT * FROM ${cloudflare_pipeline_stream.my_stream.name}"
}

For a full end-to-end example that includes R2 bucket creation, data catalog setup, and scoped API token provisioning, refer to the Pipelines Terraform documentation.

Radar - New routing widgets on Cloudflare Radar

Mon, 04 May 2026 00:00:00 GMT

Radar is expanding its Routing section ↗ with two new widgets that give a deeper view into how networks announce address space and how RPKI ROA coverage evolves over time.

Top ASes by announced IP space on country pages

Country routing pages now include a Top ASes by announced IP space chart, breaking down the IPv4 and IPv6 address space announced from a country across the autonomous systems that originate it. The chart stacks the IPv4 and IPv6 views vertically, with the top contributing ASes called out by color and the remaining networks aggregated as Other.

RPKI ROA deployment timeseries

The RPKI sub-page ↗ adds an RPKI ROA deployment timeseries widget that tracks the share of announced BGP space covered by a valid Route Origin Authorization (ROA) over time, with separate IPv4 and IPv6 lines. A toggle switches the view between the share of covered prefixes and the share of covered IP address space. The widget is available on global, country, and AS views, so operators can monitor RPKI adoption progress and compare deployment trends across different scopes.

API endpoints

The data behind these widgets is also available through two new endpoints on the BGP API:

/bgp/ips/top/ases - Returns the top autonomous systems by announced IP space (IPv4 /24s or IPv6 /48s), globally or filtered by country, snapped to the nearest 8-hour RIB boundary.
/bgp/rpki/roas/timeseries - Returns RPKI ROA validation coverage over time, by share of prefixes or share of IP address space, split by IP version, with optional ASN or location filters.

Visit the Radar routing section ↗ to explore both widgets.

WAF - WAF Release - 2026-05-04

Mon, 04 May 2026 00:00:00 GMT

This week's release focuses on new detections to expand coverage across command injection, SQL injection, PHP object injection, remote code execution, and XSS attack vectors.

Key Findings

Existing rule enhancements have been deployed to improve detection resilience against broad classes of web attacks and strengthen behavioral coverage.

Workflows, Workers - Run Workflows inside Dynamic Workers with the @cloudflare/dynamic-workflows library

Fri, 01 May 2026 00:00:00 GMT

You can now use @cloudflare/dynamic-workflows ↗ to run a Workflow inside a Dynamic Worker, ensuring durable execution for code that is loaded at runtime.

The Worker Loader loads Dynamic Workers on demand, which previously made durability challenging. Even within a Dynamic Worker, a Workflow might sleep for hours or days between steps, and by the time it resumes, the original Dynamic Worker code would no longer be in memory.

The library solves this by tagging each Workflow instance with metadata that identifies which Dynamic Worker to load — for example, a tenant ID — then reloading the matching Dynamic Worker through the Worker Loader whenever a Workflow awakens.

Because Dynamic Workers are created on-demand, you do not have to register each Workflow up front or manage them individually. Load the Workflow code in the Dynamic Worker when it is needed, and the Workflows engine handles persistence and retries behind the scenes. Your Workflow code itself is unaffected by the routing and behaves as normal.

This unlocks patterns where the Workflow code itself is dynamic. For example, this is useful with:

SaaS platforms where each tenant defines their own automation, such as onboarding sequences, approval chains, or billing retry logic.
AI agent frameworks where agents generate and execute multi-step plans at runtime, surviving restarts and waiting for human approval between tool calls.
Multi-tenant job systems where each customer submits their own processing logic and every step persists progress and retries on failure.

import {
	createDynamicWorkflowEntrypoint,
	DynamicWorkflowBinding,
	wrapWorkflowBinding,
	type WorkflowRunner,
} from "@cloudflare/dynamic-workflows";

export { DynamicWorkflowBinding };

interface Env {
	WORKFLOWS: Workflow;
	LOADER: WorkerLoader;
}

function loadTenant(env: Env, tenantId: string) {
	return env.LOADER.get(tenantId, async () => ({
		compatibilityDate: "2026-01-01",
		mainModule: "index.js",
		modules: { "index.js": await fetchTenantCode(tenantId) },
		// The Dynamic Worker uses this exactly like a real Workflow binding;
		// every create() is tagged with { tenantId } automatically.
		env: { WORKFLOWS: wrapWorkflowBinding({ tenantId }) },
	}));
}

// The entrypoint name must match `class_name` in the workflows binding of your Wrangler config file.
export const DynamicWorkflow = createDynamicWorkflowEntrypoint<Env>(
	async ({ env, metadata }) => {
		const stub = loadTenant(env, metadata.tenantId as string);
		return stub.getEntrypoint("TenantWorkflow") as unknown as WorkflowRunner;
	},
);

export default {
	fetch(request: Request, env: Env) {
		const tenantId = request.headers.get("x-tenant-id")!;
		return loadTenant(env, tenantId).getEntrypoint().fetch(request);
	},
};

Cloudflare One, Cloudflare WAN - Post-quantum IPsec interoperability with third-party devices

Thu, 30 Apr 2026 00:00:00 GMT

Cloudflare IPsec now supports post-quantum key agreement with compatible third-party devices. Cisco ↗ and Fortinet ↗ are the first third-party vendors validated to interoperate with Cloudflare IPsec using ML-KEM (Module-Lattice-Based Key-Encapsulation Mechanism).

Post-quantum IPsec uses RFC 9370 ↗ and draft-ietf-ipsecme-ikev2-mlkem ↗ to negotiate hybrid key agreement during the IKEv2 IKE_INTERMEDIATE phase. This combines classical Diffie-Hellman (Group 20) with ML-KEM-768 or ML-KEM-1024 to protect against harvest-now, decrypt-later ↗ attacks.

Key details:

Compatible with Cisco 8000 Series Secure Routers with IOS XR Release 26.1.1 and Fortinet FortiOS 7.6.6 and later.
Uses ML-KEM-768 or ML-KEM-1024 as an additional Key Exchange to DH Group 20.
Follows RFC 9370 and draft-ietf-ipsecme-ikev2-mlkem standards.
No additional licensing required.

Post-quantum IPsec with third-party devices is now generally available with confirmed interoperability for the platforms listed above. Cloudflare intends to support interoperability with more vendors as they build out support for draft-ietf-ipsecme-ikev2-mlkem. Contact your account team to discuss support for additional vendors.

For supported key exchange methods and the list of validated platforms, refer to GRE and IPsec tunnels.

Data Loss Prevention - Classify sensitive content with Data Classification

Thu, 30 Apr 2026 00:00:00 GMT

Cloudflare DLP now includes Data Classification, which lets administrators organize and label sensitive content using labels, templates, and reusable data classes.

With Data Classification, administrators can define labels such as sensitivity schemas and levels, and data tag groups and tags. Administrators can also build from Cloudflare-managed templates and create reusable data classes that combine detection entries, other data classes, sensitivity levels, and data tags.

You can then use those classifications in custom DLP profiles to identify the severity of sensitive content, understand where it exists, and apply that logic consistently across DLP profiles.

For more information, refer to Data Classification.

Data Loss Prevention - New predefined detection entries are available

Thu, 30 Apr 2026 00:00:00 GMT

Cloudflare DLP now includes new predefined detection entries.

The expanded catalog includes detections for specific credential types, webhooks, addresses, tax identifiers, national IDs, financial data, and crypto wallets.

Examples include GitHub PAT, OpenAI API Key, Slack Webhook, Discord Webhook, US Physical Address, and Bitcoin Wallet.

For the full list, refer to Predefined detection entries.

The Investigate.Get, Investigate.Move.New, and Investigate.Reclassify.New methods now use investigateID instead of postfixID as the path parameter name.

Email Security - Domains BulkDelete Method Removed

The SettingDomainService.BulkDelete method and its associated types have been removed:

SettingDomainBulkDeleteResponse
SettingDomainBulkDeleteParams

Email Security - TrustedDomains Return Type Change

SettingTrustedDomainService.New now returns *SettingTrustedDomainNewResponse instead of *SettingTrustedDomainNewResponseUnion.

Email Security - Investigate.Move Return Type Change

InvestigateMoveService.New now returns *pagination.SinglePage[InvestigateMoveNewResponse] instead of *[]InvestigateMoveNewResponse.

Workers - Observability Telemetry Filter Restructuring

The observability telemetry filter parameter types have been restructured to support nested filter groups. New discriminated union types replace the previous flat filter arrays:

ObservabilityTelemetryKeysParams.Filters now accepts FiltersObjectFilterUnion (was []interface\{\})
ObservabilityTelemetryQueryParams.Parameters.Filters now accepts FiltersObjectFilterUnion
ObservabilityTelemetryValuesParams.Filters now accepts FiltersObjectFilterUnion

New types include FiltersObjectFiltersObject (for group filters with FilterCombination) and FiltersWorkersObservabilityFilterLeaf (for leaf filters with typed Operation, Type, and Value fields).

Features

R2 - Empty buckets and delete folders from the R2 dashboard

Thu, 30 Apr 2026 00:00:00 GMT

You can now empty an entire R2 bucket or delete folders directly from the dashboard. Emptying a bucket is required before you can delete it. Previously, this required scripting or configuring lifecycle rules. Now, the dashboard can handle it in a single action.

Empty a bucket

Go to your bucket's Settings tab and select Empty under the Empty Bucket section. This deletes all objects in the bucket while preserving the bucket and its configuration. For large buckets, the operation runs in the background and the dashboard displays progress.

Emptying a bucket is also a prerequisite for deleting it. The dashboard now guides you through both steps in one place.

Delete folders

R2 uses a flat object structure. The dashboard groups objects that share a common prefix into folders when the View prefixes as directories checkbox is selected. Deleting a folder removes every object under that prefix.

From the Objects tab, you can select one or more folders and delete them alongside individual objects.

For step-by-step instructions, refer to Delete buckets and Delete objects.

Radar - Cloud Observatory connection metrics improvements

Thu, 30 Apr 2026 00:00:00 GMT

The Cloud Observatory ↗ on Radar now provides improved connection metric insights, offering new ways to explore TCP round-trip time, TCP handshake duration, TLS handshake duration, and response header receive duration across cloud provider origin servers.

The Cloud Observatory overview ↗ now shows connection metrics broken down by cloud provider, making it easy to compare connection performance across Amazon Web Services, Google Cloud, Microsoft Azure, and Oracle Cloud.

Each provider page ↗ now shows connection metrics for the top five regions, with a selector to rank by lowest or highest values.

Each region page ↗ now displays connection metrics as percentile distributions (25th percentile, median, and 75th percentile), providing insight into the range and variability of connection times.

These views are also available through the Origins API, using the timeseries_groups endpoint with the ORIGIN, REGION, or PERCENTILE dimension.

Radar - Dark mode support on Cloudflare Radar

Thu, 30 Apr 2026 00:00:00 GMT

Radar now supports dark mode. A theme selector in the upper right corner of the page lets users explicitly choose between three display options:

Light — standard light theme
Dark — full dark theme
System — follows the operating system preference

The selected theme applies consistently across all Radar pages and widgets.

The theme choice also applies to shared and embedded graphs.

Try it out at Cloudflare Radar ↗.

SDK - Cloudflare TypeScript SDK v6.0.0 Released

Thu, 30 Apr 2026 00:00:00 GMT

Full Changelog: v6.0.0-beta.2...v6.0.0 ↗

This is a major version release of the Cloudflare TypeScript SDK. It includes 11 entirely new top-level API resources, new sub-resources and methods across 50+ existing resources, SDK infrastructure improvements, and breaking changes to the generated API surface from the v5.x line.

Please ensure you read through the list of changes below before moving to this version - this will help you understand any down or upstream issues it may cause to your environments.

Breaking Changes

SDK Infrastructure

Retry-After handling changed: The SDK now respects any server-specified Retry-After value for rate-limited requests. Previously, values over 60 seconds were ignored and a default backoff was used instead.
Empty response handling: Responses with content-length: 0 now return undefined instead of attempting to parse the body.
Environment variable reading: Empty string env vars (for example, CLOUDFLARE_API_TOKEN="") are now treated as unset.
Path query parameter merging: URL search params embedded in endpoint paths are now extracted and merged into the query object.

Removed Endpoints (17)

17 HTTP endpoints were removed from the SDK, affecting abuse-reports, cloudforce-one, dlp/profiles/predefined, email-security/investigate, email-security/settings, and intel/ip-list.

Method Signature Changes

client.ai.toMarkdown.transform(file, \{ ...params \}) -> client.ai.toMarkdown.transform(\{ ...params \}) -- file moved from positional arg into params body
client.radar.ai.toMarkdown.create(body, \{ ...params \}) -> client.radar.ai.toMarkdown.create(\{ ...params \}) -- body moved from positional arg into params
client.abuseReports.create(reportType, \{ ...params \}) -> client.abuseReports.create(reportParam, \{ ...params \}) -- positional arg renamed
client.iam.userGroups.members.create(userGroupId, [ ...body ]) -> client.iam.userGroups.members.create(userGroupId, [ ...members ]) -- body array param renamed

Renamed Client Paths

client.originTLSClientAuth.hostnames.certificates -> client.originTLSClientAuth.zoneCertificates
client.radar.netflows -> client.radar.netFlows (casing change)

Return Type Changes (179)

133 methods now return null instead of a typed response object. This primarily affects delete operations across accounts, cache, d1, filters, firewall, hyperdrive, iam, kv, logpush, logs, r2, stream, workers, zero-trust, zones, and others.
17 methods changed pagination type (for example, KeysCursorPaginationAfter -> KeysCursorLimitPagination).
29 methods changed to a different named type (for example, CloudflaredCreateResponse -> CloudflareTunnel).

Removed Types (43)

24 shared types removed from root namespace (ASN, AuditLog, Member, Permission, Role, Subscription, Token, etc.). 19 response types consolidated or renamed.

Resource Restructuring

19 resources were restructured from single files to directories. Public API client paths are unchanged, but deep imports may break.

New Top-Level Resources

11 entirely new resources added to the client:

Resource	Client Path	Methods	Description
AI Search	`client.aiSearch`	46	Instances, namespaces, tokens, and items

Speed - Shared dictionaries passthrough now in open beta

Thu, 30 Apr 2026 00:00:00 GMT

Shared dictionaries (RFC 9842 ↗) let an origin compress a response against a previous version of the same resource that the browser already has cached, so only the difference between versions travels over the wire. Shared dictionaries passthrough is now in open beta on all plans.

What changed

In passthrough mode, Cloudflare:

Forwards the Use-As-Dictionary and Available-Dictionary headers between client and origin without modification.
Treats dcb (Dictionary-Compressed Brotli) and dcz (Dictionary-Compressed Zstandard) as valid Content-Encoding values end to end, without recompressing them.
Extends the cache key to vary on Available-Dictionary and Accept-Encoding so each delta-compressed variant is cached correctly.

Your origin manages the dictionary lifecycle: deciding which assets are dictionaries, attaching Use-As-Dictionary headers, and producing deltas in response to Available-Dictionary requests. Cloudflare handles the transport and the cache.

In internal testing on a 272 KB JavaScript bundle, the asset shrinks from 92.1 KB with Gzip to 2.6 KB with delta Zstandard against the previous version — a 97% reduction over standard compression — with download times improving by 81–89% versus Gzip.

Shared dictionaries work with browsers that advertise dcb or dcz in Accept-Encoding. Today, this includes Chrome 130 or later and Edge 130 or later.

Get started

Turn on passthrough for your zone with a single API call:

curl "https://api.cloudflare.com/client/v4/zones/$ZONE_ID/settings/shared_dictionary_mode" \
	--request PATCH \
	--header "Authorization: Bearer $CLOUDFLARE_API_TOKEN" \
	--json '{
		"value": "passthrough"
	}'

You can also turn it on under Speed > Settings > Content Optimization in the Cloudflare dashboard ↗. For full origin setup instructions and a working test recipe, refer to Shared dictionaries, or try the live demo at canicompress.com ↗.

WAF - WAF Release - 2026-04-30 - Emergency

Thu, 30 Apr 2026 00:00:00 GMT

This emergency release introduces a new rule to block a cPanel & WHM Authentication Bypass related to CVE-2026-41940.

Key Findings

CVE-2026-41940: A critical authentication bypass vulnerability in cPanel & WHM allows unauthenticated remote attackers to bypass authentication mechanisms and gain unauthorized administrative access to the web hosting control panel. This vulnerability affects the session validation logic, enabling attackers to craft malicious requests that circumvent normal authentication checks.

Impact

Successful exploitation allows unauthenticated attackers to gain administrative control over affected cPanel & WHM installations. This leads to complete server compromise, potential theft or manipulation of hosted data, and significant service disruption across managed environments.

We strongly recommend applying official vendor patches for cPanel & WHM immediately to address the underlying vulnerability.

Ruleset	Rule ID	Legacy Rule ID	Description	Previous Action	New Action	Comments
Cloudflare Managed Ruleset		N/A	cPanel - Auth Bypass - CVE:CVE-2026-41940	N/A	Block	This is a new detection.

Cloudflare Web Analytics - Web Analytics adds Navigation Type filtering and reporting

Thu, 30 Apr 2026 00:00:00 GMT

Cloudflare Web Analytics now supports Navigation Type reporting and filtering.

This update allows developers and performance analysts to see how users are navigating between pages — whether through a link click or form submission, a page reload, or using the browser's back/forward buttons — and whether a browser cache hit occurred for these behaviors.

Understanding navigation types is critical for optimizing user experience. For example, if a high volume of your traffic consists of "Back-forward" navigations versus "Back-forward Cache", those visitors are not benefiting from the Back/Forward Cache (bfcache) and therefore are experiencing higher load times due to potentially unnecessary network requests.

The same applies for regular "Navigate" entries — where "Navigate Cache", "Navigate Prefetch Cache" and "Prerender" would provide instant document retrieval — and "Reload", where "Reload cache" would be more optimal.

A high volume of "Reload" entries can also indicate a potential stability problem with your website.

By identifying these patterns, you can tune your browser caching strategies to ensure HTML documents are served instantaneously from local caches rather than requiring a roundtrip to the network.

For more information, refer to Navigation Types.

Key benefits

Monitor Cache Effectiveness: See how often your site is served from the HTTP cache or bfcache.
Identify Performance Bottlenecks: Filter by the different types to understand performance opportunity of improving browser cache hit ratio.

You can now find the Navigation Type dimension in the Web Analytics dashboard. You can filter to include/exclude one or more specific types using "equals", "does not equal", "in", or "not in" matchers.

To check the list of popular navigation types, select Page views on the Web Analytics sidebar and scroll down to the bottom:

Digital Experience Monitoring - Digital experience tests to authenticated resources and enhanced configuration

Wed, 29 Apr 2026 00:00:00 GMT

Digital experience tests now support testing applications protected by Cloudflare Access or third-party authentication. All authentication secrets are managed via Cloudflare Secret Store.

Digital experience tests also have enhanced configuration options including:

New HTTP methods (DELETE, PATCH, POST, PUT)
Secret Store headers, custom plain text headers, and custom request bodies
Advanced settings: follow redirects, response bodies, response headers, and allow untrusted certificates

Cloudflare Fundamentals - Instant Bank Payments via Link

Wed, 29 Apr 2026 00:00:00 GMT

You can now pay for Cloudflare services directly from your bank account using Instant Bank Payments via Link.

What changed

Link ↗ now supports bank account payments in addition to cards. If you have a bank account saved in Link, it appears as a payment option at checkout. If not, you can connect one during the checkout flow.

How to use it

During checkout, select your bank account from your saved Link payment methods.
Confirm the payment.

After your first Link authentication, your bank account is available for future purchases without re-entering details.

Who is eligible

Instant Bank Payments via Link is available to US-based self-serve accounts across all Cloudflare products. Your existing cards remain available at checkout.

Bank-based Link payments appear in your billing history with the payment method shown as link and last four digits as 0000. For details, refer to the Instant Bank Payments via Link documentation.

Gateway - Gateway Authorization Proxy and hosted PAC files are now generally available

Wed, 29 Apr 2026 00:00:00 GMT

The Gateway Authorization Proxy and hosted PAC files are now generally available for all plan types.

Authorization proxy endpoints add an identity-aware option alongside the existing source IP proxy endpoints, using Cloudflare Access authentication to verify who a user is before applying Gateway filtering — without installing the Cloudflare One Client. Cloudflare-hosted PAC files let you create and distribute PAC files directly from Cloudflare One on Cloudflare's global network.

These features are ideal for environments where deploying a device client is not an option, such as virtual desktops (VDI) or compliance-restricted endpoints.

To get started, refer to the proxy endpoints documentation.

Hyperdrive - Hyperdrive support for private databases with Workers VPC

Wed, 29 Apr 2026 00:00:00 GMT

You can now connect Hyperdrive to a private database through a Workers VPC service. This is the recommended way to connect Hyperdrive to a private database that is not exposed to the public Internet.

When creating a Hyperdrive configuration in the Cloudflare dashboard, choose Connect to private database and then Workers VPC. From there, you can select an existing VPC service or create a new one inline by picking a Cloudflare Tunnel and entering your origin host and TCP port.

You can also create a Hyperdrive configuration backed by a Workers VPC service from the command line:

npx wrangler hyperdrive create my-vpc-database \
  --service-id <YOUR_VPC_SERVICE_ID> \
  --database <DATABASE_NAME> \
  --user <DATABASE_USER> \
  --password <DATABASE_PASSWORD> \
  --scheme postgresql

Workers VPC services are reusable across Hyperdrive configurations and can also be bound directly to Workers, so you can share the same private connection across multiple products.

To get started, refer to Connect Hyperdrive to a private database using Workers VPC.

Digital Experience Monitoring - Internet outage notifications for devices

Tue, 28 Apr 2026 00:00:00 GMT

Digital Experience will display a dashboard notification when an Internet outage or traffic anomaly may impact a Cloudflare One Client device based on its geographic location or network connection.

This Internet outage and traffic anomaly data is pulled from Cloudflare Radar ↗. All Internet outage and traffic anomaly observations can be viewed in the Radar Outage Center ↗.

Digital Experience Monitoring - Cloudflare One Client speed tests

Tue, 28 Apr 2026 00:00:00 GMT

IT teams can now remotely run speed tests from the Cloudflare One Client to Cloudflare's network edge.

Each speed test includes the following metrics:

Internet speed: download and upload throughput
Latency: download, upload, unloaded latency, and jitter
Network quality score: video streaming, webchat/real-time communication (RTC)

In the Cloudflare dashboard ↗, go to Zero Trust > Insights > Digital experience > Diagnostics and select Run diagnostics to use the feature today.

Data Loss Prevention - Create and manage DLP detection entries outside of profiles

Tue, 28 Apr 2026 00:00:00 GMT

You can now create, view, and manage DLP detection entries outside of profiles.

Detection entries are no longer hidden inside individual profiles. Administrators can manage detection entries directly from the Detection entries section and use them in custom DLP profiles.

For more information, refer to Configure detection entries.

Data Loss Prevention - Detect PII records with a new predefined DLP profile

Tue, 28 Apr 2026 00:00:00 GMT

Cloudflare DLP now includes a new predefined profile designed to detect PII records that contain multiple types of personal data: Personally Identifiable Information (PII) Record.

Most predefined and custom DLP profiles match when any enabled detection entry matches. The Personally Identifiable Information (PII) Record profile is different. It only matches when at least three unique detection entries are found in close proximity, which reduces false positives from standalone values that may not represent a real PII record.

Detection entries included in the profile:

AU Passport Number
American Express Card Number
Diners Club Card Number
US Driver's License Number
Email Address
Full Name
US Mailing Address
Mastercard Card Number
US Individual Tax Identification Number (ITIN)
US Passport Number
US Phone Number
Union Pay Card Number
United States SSN Numeric Detection
Visa Card Number

For more information, refer to predefined DLP profiles.

DNS - Account-level enforce DNS-only

Tue, 28 Apr 2026 00:00:00 GMT

You can now disable Cloudflare's reverse proxy across all zones in your account simultaneously using the new enforce_dns_only setting. When enabled, Cloudflare responds to DNS queries for all proxied records with your origin IP addresses instead of Cloudflare's anycast IPs. This account-level kill switch is designed for incident response scenarios where you need to quickly route traffic directly to your origin servers.

Key characteristics

Account-level — Affects all zones in the account simultaneously with a single API call.
Non-destructive — Does not modify your DNS records. Disabling the setting restores normal proxy behavior.
API-only — Available through the API only, not in the Cloudflare dashboard.

What's affected

Included: Standard proxied A, AAAA, and CNAME records, Load Balancing records, and records matching Worker routes.

Queues - Realtime backlog metrics now available for Queues

Tue, 28 Apr 2026 00:00:00 GMT

Queues, Cloudflare's managed message queue, now exposes realtime backlog metrics via the dashboard, REST API, and JavaScript API. Three new fields are available:

backlog_count — the number of unacknowledged messages in the queue
backlog_bytes — the total size of those messages in bytes
oldest_message_timestamp_ms — the timestamp of the oldest unacknowledged message

The following endpoints also now include a metadata.metrics object on the result field after successful message consumption:

/accounts/{account_id}/queues/{queue_id}/messages/pull
/accounts/{account_id}/queues/{queue_id}/messages
/accounts/{account_id}/queues/{queue_id}/messages/batch

Javascript APIs

Call env.QUEUE.metrics() to get realtime backlog metrics:

const {
	backlogCount, // number
	backlogBytes, // number
	oldestMessageTimestamp, // Date | undefined
} = await env.QUEUE.metrics();

env.QUEUE.send() and env.QUEUE.sendBatch() also now return a metrics object on the response.

You can also query these fields via the GraphQL Analytics API or view realtime backlog on the dashboard ↗.

For more information, refer to Queues metrics.

Support - Direct access to Support from the dashboard

Tue, 28 Apr 2026 00:00:00 GMT

Direct access to Support from the dashboard

The Support button in the dashboard global navigation header now takes you directly to the Cloudflare Support Portal ↗, eliminating the previous dropdown menu.

This change ensures that when you need help, you spend less time navigating the UI and more time getting the answers you need.

What changed?

Previous behavior: Selecting ? Support opened a dropdown menu with various links (Help Center, Cloudflare Community, etc.).
New behavior: Selecting Support immediately redirects your current tab to the Support Portal.

To learn more about the resources available to you, refer to the Cloudflare Support documentation ↗.

Cache - Cache Response Rules now support zone versioning

Mon, 27 Apr 2026 00:00:00 GMT

Cache Response Rules now work with Version Management. You can version response-phase cache settings and promote them through environments, just like Cache Rules and other supported configurations.

What changed

Previously, Cache Response Rules were excluded from zone versioning. Any response-phase rule you created applied globally across all environments with no way to test changes in staging first. Cache Rules already supported versioning, but the response phase, where you modify Cache-Control directives, manage cache tags, and strip headers, did not.

Cache Response Rules are now fully integrated with Version Management. You can create or modify response-phase rules within a version, and those changes stay scoped to that version until promoted.

Benefits

Safe rollout of cache behavior changes: Test response-phase rules in a staging environment before promoting to production. Catch unintended caching side effects early.
Parity with Cache Rules: Cache Response Rules now follow the same versioning workflow as Cache Rules, so you can manage all cache configuration through a single promotion pipeline.
Independent environment control: Run different response-phase cache settings per environment. For example, strip Set-Cookie headers in staging to validate cacheability without affecting production traffic.

Get started

Configure Cache Response Rules in the Cloudflare dashboard ↗ under Caching > Cache Rules, or via the Rulesets API. For more details, refer to the Cache Response Rules documentation and the Version Management documentation.

Cloudflare Fundamentals - Structured error responses for Cloudflare 5xx errors

Mon, 27 Apr 2026 00:00:00 GMT

Cloudflare-generated 5xx error responses now return structured JSON and Markdown when agents request them, matching the format already available for 1xxx errors. Responses follow RFC 9457 (Problem Details for HTTP APIs) ↗ and include a Retry-After HTTP header on retryable codes.

Changes

5xx coverage. Ten Cloudflare-generated error codes (500, 502, 504, 520-526) now serve structured responses. These are errors Cloudflare itself generates when it cannot reach or understand the origin server. Origin-generated 5xx responses that Cloudflare passes through are not affected.

Fault attribution. The error_category field tells agents where the fault lies:

origin (502, 504, 520-524) — the origin server is responsible. Transient; retry with the backoff in retry_after.
cloudflare (500) — Cloudflare's fault, not the website or the request. Short retry.
ssl (525, 526) — the origin's TLS configuration is broken. Do not retry.

Retry-After header. Retryable codes (500, 502, 504, 520-524) include a Retry-After HTTP header matching the retry_after body field. Non-retryable codes (525, 526) do not include the header.

Negotiation behavior

Request header sent	Response format
`Accept: application/json`	JSON (`application/json` content type)
`Accept: application/problem+json`	JSON (`application/problem+json` content type)
`Accept: application/json, text/markdown;q=0.9`	JSON
`Accept: text/markdown`	Markdown
`Accept: text/markdown, application/json`	Markdown (equal `q`, first-listed wins)
`Accept: /`	HTML (default)

Availability

Available now for all zones on all plans.

Get started

Get JSON response for error 522:

curl -s --compressed -H "Accept: application/json" -A "TestAgent/1.0" -H "Accept-Encoding: gzip, deflate" "<YOUR_DOMAIN>/cdn-cgi/error/522" | jq .

Check presence of the Retry-After HTTP header associated with the JSON response for error 521:

curl -s --compressed -D - -o /dev/null -H "Accept: application/json" -A "TestAgent/1.0" -H "Accept-Encoding: gzip, deflate" "<YOUR_DOMAIN>/cdn-cgi/error/521" | grep -i retry-after

Cloudflare Fundamentals, Resource Tagging - Resource Tagging enters public beta

Mon, 27 Apr 2026 00:00:00 GMT

Resource Tagging is now in public beta and rolling out to all Cloudflare accounts over the coming days. You can attach custom key-value metadata to your Cloudflare resources and query across your entire account to find what you need.

What's included

Broad resource type support — Tag zones, custom hostnames, Cloudflare Tunnels, Workers, D1 databases, R2 buckets, KV namespaces, Durable Object namespaces, Queues, Stream videos, Images, Access applications, Gateway rules, AI Gateways, and more. Refer to the full list of supported resource types.
Powerful filtering — Query tagged resources using AND/OR logic, negation, and key-only matching. Combine up to 20 filters per query to build precise resource views.
Account and zone-level endpoints — Full CRUD operations across both scopes.
Token-based authentication — Tagging supports Account Owned Tokens that persist independently of individual users, so your automation keeps running through credential rotations and team changes.
Flexible role support — Super Administrators, Workers Admins, and Tag Admins can all manage tags.

API-first by design

The API is the primary interface for Resource Tagging and the recommended path for all workflows — scripting tag assignments, building CI/CD pipelines, or integrating with your infrastructure-as-code toolchain.

Dashboard UI

You can also view and manage tagged resources directly in the Cloudflare dashboard. Navigate to Manage Account > Resource Tagging to see all tagged resources across your account, filter by resource name or tag, and add or edit tags inline.

What's coming next

In future releases, expect support for additional resource types across the Cloudflare platform, tag-based access control policies for scoping user permissions to tagged resources, billing and usage attribution by tag for breaking down costs by team, project, or environment, and Terraform provider support for managing tags declaratively.

Current limitations

PUT replaces all tags on a resource (no partial update). Use the GET, merge, PUT workflow to modify individual tags safely.
DELETE removes all tags from a resource. To remove a single tag, PUT the remaining tags back.
Querying tags for a resource that has never been tagged returns 500 instead of 404. This is a known beta limitation.

To get started, refer to the Resource Tagging documentation.

Security Center - Unified workspace for Brand Protection

Mon, 27 Apr 2026 00:00:00 GMT

We have introduced a unified investigation workspace within Brand Protection to help analysts manage complex brand portfolios. Instead of jumping between individual queries, you can now consolidate your workflow into a single, cohesive view.

What's new

You can now elect multiple saved queries from your dashboard to generate a consolidated "Combined Matches" view. This allows you to triage results from different brand queries in one unified table
You can open query extended views in distinct tabs within the Brand Protection dashboard. This enables you to maintain multiple investigation contexts simultaneously and switch between them without losing your place.
You can reset your workspace using the new "Clear Selection" action, making it easier to pivot between different investigation sets.

Key benefits

Eliminate fragmented workflows by viewing all matches across different query buckets in a single table, reducing the need to click through dozens of individual query pages
Correlate related campaigns by seeing similar domains or infrastructure patterns that appear across multiple saved queries

Learn more in our Brand Protection documentation.

Gateway, Cloudflare One - Network Session Logs now available for all on-ramps

Fri, 24 Apr 2026 00:00:00 GMT

Zero Trust Network Session Logs are now generated for all traffic proxied through Cloudflare Gateway, regardless of on-ramp type. This includes traffic from proxy endpoints (PAC files) and Browser Isolation egress — on-ramps that previously did not generate session logs.

Customers who already consume the zero_trust_network_sessions dataset via Logpush or Log Explorer may see increased log volume if they use these on-ramps.

For field definitions, refer to Zero Trust Network Session Logs. For traffic analysis, refer to Network session analytics.

Terraform - Automate migration from Cloudflare's Terraform v4 to v5 provider

Fri, 24 Apr 2026 00:00:00 GMT

We're excited to announce tf-migrate, a purpose-built CLI tool that simplifies migrating from Cloudflare Terraform Provider v4 to v5.

v5 is stable and ready for production

Terraform Provider v5 is stable and actively receiving updates. We encourage all users to migrate to v5 to take advantage of ongoing enhancements and new capabilities.

Cloudflare uses tf-migrate to migrate our own infrastructure — the same tool we're providing to the community — ensuring the best possible migration experience.

What tf-migrate does

tf-migrate automates the tedious and error-prone parts of the v4 to v5 migration process:

Resource type renames – Automatically updates cloudflare_record → cloudflare_dns_record, cloudflare_access_application → cloudflare_zero_trust_access_application, and 40+ other renamed resources
Attribute transformations – Updates field names (e.g., value → content for DNS records) and restructures nested blocks
Moved block generation – Creates Terraform 1.8+ moved blocks to prevent resource replacements and ensure zero-downtime migrations
Cross-file reference updates – Automatically finds and updates all references to renamed resources across your entire configuration
Dry-run mode – Preview all changes before applying them to ensure safety

Combined with the automatic state upgraders introduced in v5.19+, tf-migrate eliminates the manual work and risk that previously made v5 migrations challenging. Tf-migrate operates directly on the config, and the built-in state upgraders handle the rest.

Supported resources

Tf-migrate currently supports the most common Terraform resources our customers use. We are actively working to expand coverage, with the most commonly used resources prioritized first.

For the complete list of supported resources and their migration status, refer to the v5 Stabilization Tracker ↗. This list is updated regularly as additional resources are stabilized and migration support is added.

Resources not yet supported by tf-migrate will need to be migrated manually using the version 5 upgrade guide ↗. The upgrade guide provides step-by-step instructions for handling resource renames, attribute changes, and state migrations.

Get started

We have been releasing Betas over the past month and a half while testing this tool. See the full changelog of those Betas here: tf-migrate releases ↗.

Access - AAGUID restrictions and AMR matching for Access independent MFA

Thu, 23 Apr 2026 00:00:00 GMT

Independent MFA in Cloudflare Access now supports two additional organization-level controls:

Restrict authenticators by AAGUID — Limit enrollment to a specific set of WebAuthn authenticators using their AAGUID ↗. This is useful for organizations that require FIPS-validated security keys or company-issued hardware. AAGUIDs are managed through a new List type.
AMR matching — Skip the independent MFA prompt when the identity provider has already performed an equivalent MFA. Access reads the amr claim defined in RFC 8176 ↗ and matches supported values such as hwk, otp, and fpt to the authenticator types allowed on the application or policy. This prevents users from having to complete MFA twice when their identity provider already enforces it.

To get started, refer to Independent MFA.

Audit Logs - Audit Logs v2 — Organization-level support

Thu, 23 Apr 2026 00:00:00 GMT

Audit Logs v2 now supports organization-level audit logs. Org Admins can retrieve audit events for actions performed at the organization level via the Audit Logs v2 API.

To retrieve organization-level audit logs, use the following endpoint:

GET https://api.cloudflare.com/client/v4/organizations/{organization_id}/logs/audit

This release covers user-initiated actions performed through organization-level APIs. Audit logs for system-initiated actions, a dashboard UI, and Logpush support for organizations will be added in future releases.

For more information, refer to the Audit Logs documentation.

SDK, Go SDK - Go SDK v6.10.0 Released

Thu, 23 Apr 2026 00:00:00 GMT

v6.10.0

In this release, you'll see a number of breaking changes. This is primarily due to changes in OpenAPI definitions, which our libraries are based off of, and codegen updates that we rely on to read those OpenAPI definitions and produce our SDK libraries.

Please ensure you read through the list of changes below before moving to this version - this will help you understand any down or upstream issues it may cause to your environments.

Breaking Changes

See the v6.10.0 Migration Guide ↗ for before/after code examples and actions needed for each change.

Analytics, Log Explorer - Custom dashboards available to all customers

Wed, 22 Apr 2026 00:00:00 GMT

Custom Dashboards are now available to all Cloudflare customers. Build personalized views that highlight the metrics most critical to your infrastructure and security posture, moving beyond standard product dashboards.

This update significantly expands the data available for visualization. Build charts based on any of the 100+ datasets available via the Cloudflare GraphQL API, covering everything from WAF events and Workers metrics to Load Balancing and Zero Trust logs.

Log Explorer integration

For Log Explorer customers, you can now turn raw log queries directly into dashboard charts. When you identify a specific pattern or spike while investigating logs, save that query as a visualization to monitor those signals in real-time without leaving the dashboard.

Key benefits

Unified visibility: Consolidate signals from different Cloudflare products (for example, HTTP Traffic and R2 Storage) into a single view.
Flexible monitoring: Create charts that focus on specific status codes, ASN regions, or security actions that matter to your business.
Expanded limits: Log Explorer customers can create up to 100 dashboards (up from 25 for standard customers).

To get started, refer to the Custom Dashboards documentation.

R2, R2 Data Catalog - R2 Data Catalog snapshot expiration now removes unreferenced data files

Wed, 22 Apr 2026 00:00:00 GMT

R2 Data Catalog, a managed Apache Iceberg ↗ catalog built into R2, now removes unreferenced data files during automatic snapshot expiration. This improvement reduces storage costs and eliminates the need to run manual maintenance jobs to reclaim space from deleted data.

Previously, snapshot expiration only cleaned up Iceberg metadata files such as manifests and manifest lists. Data files that were no longer referenced by active snapshots remained in R2 storage until you manually ran remove_orphan_files or expire_snapshots through an engine like Spark. This required extra operational overhead and left stale data files consuming storage.

Snapshot expiration now handles both metadata and data file cleanup automatically. When a snapshot is expired, any data files that are no longer referenced by retained snapshots are removed from R2 storage.

# Enable catalog-level snapshot expiration
npx wrangler r2 bucket catalog snapshot-expiration enable my-bucket \
  --older-than-days 7 \
  --retain-last 10

For more information, refer to the table maintenance documentation.

Cloudflare Network Firewall, Magic Transit, Cloudflare WAN - Country rules supported in Unified Routing

Tue, 21 Apr 2026 12:00:00 GMT

Cloudflare Advanced Network Firewall Country rules are now supported for accounts using Unified Routing mode. This feature requires a Cloudflare Advanced Network Firewall subscription.

You can create firewall rules that match traffic based on source or destination country to enforce geographic access policies across your network.

This is the first of the Cloudflare Advanced Network Firewall features to become available in Unified Routing. Support for additional features - IP Lists, ASN Lists, Threat Intel Lists, IDS, Rate Limiting, SIP, and Managed Rulesets - is planned.

For the full list of current beta limitations, refer to Traffic steering beta limitations.

Cloudflare Fundamentals - Network Overview page in the dashboard

Tue, 21 Apr 2026 12:00:00 GMT

A new Network Overview page in the Cloudflare dashboard gives you a single starting point for network security and connectivity products.

From the Network Overview page, you can:

Connect resources with Cloudflare Tunnel - Create tunnels to connect your infrastructure to Cloudflare without exposing it to the public Internet.
Monitor traffic with Network Flow - Get real-time visibility into traffic volume from your routers.
Configure Address Maps - Map dedicated static IPs or BYOIP prefixes to specific hostnames.
Explore Magic Transit and Cloudflare WAN - Set up DDoS protection for your networks and connectivity for your branch offices and data centers.

To find it, go to Networking ↗ in the dashboard sidebar.

If you already use Magic Transit, Cloudflare WAN, or other Cloudflare network services products, your existing experience is unchanged.

Workflows - Additional step context and ReadableStream support now available in Workflows step.do()

Tue, 21 Apr 2026 12:00:00 GMT

Workflows now provides additional context inside step.do() callbacks and supports returning ReadableStream to handle larger step outputs.

Step context properties

The step.do() callback receives a context object with new properties alongside attempt:

step.name — The name passed to step.do()
step.count — How many times a step with that name has been invoked in this instance (1-indexed)
- Useful when running the same step in a loop.
config — The resolved step configuration, including timeout and retries with defaults applied

type ResolvedStepConfig = {
	retries: {
		limit: number;
		delay: WorkflowDelayDuration | number;
		backoff?: "constant" | "linear" | "exponential";
	};
	timeout: WorkflowTimeoutDuration | number;
};

type WorkflowStepContext = {
	step: {
		name: string;
		count: number;
	};
	attempt: number;
	config: ResolvedStepConfig;
};

ReadableStream support in `step.do()`

Steps can now return a ReadableStream directly. Although non-stream step outputs are limited to 1 MiB, streamed outputs support much larger payloads.

const largePayload = await step.do("fetch-large-file", async () => {
	const object = await env.MY_BUCKET.get("large-file.bin");
	return object.body;
});

Note that streamed outputs are still considered part of the Workflow instance storage limit.

Containers - Container logs page now includes relevant Worker and Durable Object logs

Tue, 21 Apr 2026 00:00:00 GMT

The Container logs page now displays related Worker and Durable Object logs alongside container logs. This co-locates all relevant log events for a container application in one place, making it easier to trace requests and debug issues.

You can filter to a single source when you need to isolate Container, Worker, or Durable Object output.

For information on configuring container logging, refer to How do Container logs work?.

Cloudflare Fundamentals, Workers - Introducing Billable Usage dashboard and Budget alerts

Tue, 21 Apr 2026 00:00:00 GMT

Pay-as-you-go customers can now monitor usage-based costs and configure spend alerts through two new features: the Billable Usage dashboard and Budget alerts.

Billable Usage dashboard

The Billable Usage dashboard provides daily visibility into usage-based costs across your Cloudflare account. The data comes from the same system that generates your monthly invoice, so the figures match your bill.

The dashboard displays:

A bar chart showing daily usage charges for your billing period
A sortable table breaking down usage by product, including total usage, billable usage, and cumulative costs
Ability to view previous billing periods

Usage data aligns to your billing cycle, not the calendar month. The total usage cost shown at the end of a completed billing period matches the usage overage charges on your corresponding invoice.

To access the dashboard, go to Manage Account > Billing > Billable Usage.

Budget alerts

Budget alerts allow you to set dollar-based thresholds for your account-level usage spend. You receive an email notification when your projected monthly spend reaches your configured threshold, giving you proactive visibility into your bill before month-end.

To configure a budget alert:

Go to Manage Account > Billing > Billable Usage.
Select Set Budget Alert.
Enter a budget threshold amount greater than $0.
Select Create.

Alternatively, configure alerts via Notifications > Add > Budget Alert.

You can create multiple budget alerts at different dollar amounts. The notifications system automatically deduplicates alerts if multiple thresholds trigger at the same time. Budget alerts are calculated daily based on your usage trends and fire once per billing cycle when your projected spend first crosses your threshold.

Both features are available to Pay-as-you-go accounts with usage-based products (Workers, R2, Images, etc.). Enterprise contract accounts are not supported.

For more information, refer to the Usage based billing documentation.

Logs - Logpush subrequest merging for HTTP requests

Tue, 21 Apr 2026 00:00:00 GMT

When a Cloudflare Worker intercepts a visitor request, it can dispatch additional outbound fetch calls called subrequests. By default, each subrequest generates its own log entry in Logpush, resulting in multiple log lines per visitor request. With subrequest merging enabled, subrequest data is embedded as a nested array field on the parent log record instead.

What's new

New subrequest_merging field on Logpush jobs — Set "merge_subrequests": true when creating or updating an http_requests Logpush job to enable the feature.
New Subrequests log field — When subrequest merging is enabled, a Subrequests field (array\<object\>) is added to each parent request log record. Each element in the array contains the standard http_requests fields for that subrequest.

Limitations

Applies to the http_requests (zone-scoped) dataset only.
A maximum of 50 subrequests are merged per parent request. Subrequests beyond this limit are passed through unmodified as individual log entries.
Subrequests must complete within 5 minutes of the visitor request. Subrequests that exceed this window are passed through unmodified.
Subrequests that do not qualify appear as separate log entries — no data is lost.
Subrequest merging is being gradually rolled out and is not yet available on all zones. Contact your account team for concerns or to ensure it is enabled for your zone.
For more information, refer to Subrequests.

WAF - WAF Release - 2026-04-21

Tue, 21 Apr 2026 00:00:00 GMT

This week's release introduces a new detection for a Remote Code Execution (RCE) vulnerability in Apache ActiveMQ (CVE-2026-34197) and an updated signature for Magento 2 - Unrestricted File Upload. Alongside these detections, we are continuing our work on rule refinements to provide deeper security insights for our customers.

Key Findings

Apache ActiveMQ (CVE-2026-34197): A vulnerability in Apache ActiveMQ allows an unauthenticated, remote attacker to execute arbitrary code. This flaw occurs during the processing of specially crafted network packets, leading to potential full system compromise.
Magento 2 - Unrestricted File Upload - 2: This is a follow-up enhancement to our existing protections for Magento and Adobe Commerce.

Impact

Successful exploitation of these vulnerabilities could allow unauthenticated attackers to execute arbitrary code or gain full administrative control over affected servers. We strongly recommend applying official vendor patches for Apache ActiveMQ and Magento to address the underlying vulnerabilities.

Workers - WebSocket binary messages now delivered as Blob by default

Tue, 21 Apr 2026 00:00:00 GMT

Binary frames received on a WebSocket are now delivered to the message event as Blob ↗ objects by default. This matches the WebSocket specification ↗ and standard browser behavior. Previously, binary frames were always delivered as ArrayBuffer ↗. The binaryType property on WebSocket controls the delivery type on a per-WebSocket basis.

This change has been active for Workers with compatibility dates on or after 2026-03-17, via the websocket_standard_binary_type compatibility flag. We should have documented this change when it shipped but didn't. We're sorry for the trouble that caused. If your Worker handles binary WebSocket messages and assumes event.data is an ArrayBuffer, the frames will arrive as Blob instead, and a naive instanceof ArrayBuffer check will silently drop every frame.

To opt back into ArrayBuffer delivery, assign binaryType before calling accept(). This works regardless of the compatibility flag:

const resp = await fetch("https://example.com", {
	headers: { Upgrade: "websocket" },
});
const ws = resp.webSocket;

// Opt back into ArrayBuffer delivery for this WebSocket.
ws.binaryType = "arraybuffer";
ws.accept();

ws.addEventListener("message", (event) => {
	if (typeof event.data === "string") {
		// Text frame.
	} else {
		// event.data is an ArrayBuffer because we set binaryType above.
	}
});

If you are not ready to migrate and want to keep ArrayBuffer as the default for all WebSockets in your Worker, add the no_websocket_standard_binary_type flag to your Wrangler configuration file.

This change has no effect on the Durable Object hibernatable WebSocket webSocketMessage handler, which continues to receive binary data as ArrayBuffer.

For more information, refer to WebSockets binary messages.

Logs, Pipelines - Cloudflare Pipelines as a Logpush destination

Mon, 20 Apr 2026 00:00:00 GMT

Logpush has traditionally been great at delivering Cloudflare logs to a variety of destinations in JSON format. While JSON is flexible and easily readable, it can be inefficient to store and query at scale.

With this release, you can now send your logs directly to Pipelines to ingest, transform, and store your logs in R2 as Parquet files or Apache Iceberg tables managed by R2 Data Catalog. This makes the data footprint more compact and more efficient at querying your logs instantly with R2 SQL or any other query engine that supports Apache Iceberg or Parquet.

Transform logs before storage

Pipelines SQL runs on each log record in-flight, so you can reshape your data before it is written. For example, you can drop noisy fields, redact sensitive values, or derive new columns:

INSERT INTO http_logs_sink
SELECT
  ClientIP,
  EdgeResponseStatus,
  to_timestamp_micros(EdgeStartTimestamp) AS event_time,
  upper(ClientRequestMethod) AS method,
  sha256(ClientIP) AS hashed_ip
FROM http_logs_stream
WHERE EdgeResponseStatus >= 400;

Pipelines SQL supports string functions, regex, hashing, JSON extraction, timestamp conversion, conditional expressions, and more. For the full list, refer to the Pipelines SQL reference.

Get started

To configure Pipelines as a Logpush destination, refer to Enable Cloudflare Pipelines.

R2 SQL - R2 SQL adds JSON functions, EXPLAIN FORMAT JSON, and unpartitioned table support

Mon, 20 Apr 2026 00:00:00 GMT

R2 SQL is Cloudflare's serverless, distributed, analytics query engine for querying Apache Iceberg ↗ tables stored in R2 Data Catalog.

R2 SQL now supports functions for querying JSON data stored in Apache Iceberg tables, an easier way to parse query plans with EXPLAIN FORMAT JSON, and querying tables without partition keys stored in R2 Data Catalog.

JSON functions extract and manipulate JSON values directly in SQL without client-side processing:

SELECT
  json_get_str(doc, 'name') AS name,
  json_get_int(doc, 'user', 'profile', 'level') AS level,
  json_get_bool(doc, 'active') AS is_active
FROM my_namespace.sales_data
WHERE json_contains(doc, 'email')

For a full list of available functions, refer to JSON functions.

EXPLAIN FORMAT JSON returns query execution plans as structured JSON for programmatic analysis and observability integrations:

npx wrangler r2 sql query "${WAREHOUSE}" "EXPLAIN FORMAT JSON SELECT * FROM logpush.requests LIMIT 10;"

Security Overview - Archive and audit security action items

Mon, 20 Apr 2026 00:00:00 GMT

Archive and audit security action items

Introducing enhanced archiving capabilities for security action items within the Security Overview dashboard. This update allows security teams to maintain a cleaner workspace by removing resolved, accepted, or irrelevant items from their active list while maintaining a clear paper trail for compliance.

Why this matters

Managing a high volume of security insights can be overwhelming. Previously, users lacked a structured way to dismiss items without losing the context of why they were ignored.

With these new archiving options—False Positive, Accept Risk, and Other—you can now suppress items indefinitely with required rationale text for risk-based decisions. This ensures that your team remains focused on critical, actionable vulnerabilities while preserving institutional knowledge for audits.

Key features

Structured Archiving: Choose from specific categories to define why an action item is being moved.
Required Rationale: For "Accept Risk" and "Other" categories, users must provide documentation, ensuring accountability for security decisions.
Audit Log Transparency: New API endpoints allow you to programmatically retrieve the history of status changes and rationale for any insight at the account or zone level.
Reversible Actions: Any archived item can be moved back to the active list at any time if the security context changes.

:::note Archiving a suspicious activity item will remove it from the Security Overview page, but the activity will remain visible in your Security Analytics dashboard for deeper forensic analysis. :::

Example: Retrieve audit logs via API

To review the history and rationale of a specific archived issue at the account level, you can use the following API command:

curl "[https://api.cloudflare.com/client/v4/accounts/](https://api.cloudflare.com/client/v4/accounts/){account_id}/insights/{insight_id}/audit-log" \
     -H "Authorization: Bearer <API_TOKEN>" \
     -H "Content-Type: application/json"

AI Crawl Control - Introducing Redirects for AI Training

Fri, 17 Apr 2026 00:00:00 GMT

Cloudflare's network now supports redirecting verified AI training crawlers to canonical URLs when they request deprecated or duplicate pages. When enabled via AI Crawl Control > Quick Actions, AI training crawlers that request a page with a canonical tag pointing elsewhere receive a 301 redirect to the canonical version. Humans, search engine crawlers, and AI Search agents continue to see the original page normally.

This feature leverages your existing <link rel="canonical"> tags. No additional configuration required beyond enabling the toggle. Available on Pro, Business, and Enterprise plans at no additional cost.

Refer to the Redirects for AI Training documentation for details.

AI Crawl Control - Tools to prepare your site for the agentic Internet

Fri, 17 Apr 2026 00:00:00 GMT

AI Crawl Control now includes new tools to help you prepare your site for the agentic Internet—a web where AI agents are first-class citizens that discover and interact with content differently than human visitors.

Content Format insights

The Metrics tab now includes a Content Format chart showing what content types AI systems request versus what your origin serves. Understanding these patterns helps you optimize content delivery for both human and agent consumption.

Directives tab (formerly Robots.txt)

The Robots.txt tab has been renamed to Directives and now includes a link to check your site's Agent Readiness ↗ score.

Refer to our blog post on preparing for the agentic Internet ↗ for more on why these capabilities matter.

Cache - Smart Tiered Cache optimizes public cloud origins

Fri, 17 Apr 2026 00:00:00 GMT

You can now achieve higher cache HIT rates and reduce origin load for origins hosted on public cloud providers with Smart Tiered Cache. By setting a cloud region hint for your origin, Cloudflare selects the optimal upper-tier data center for that cloud region, funneling all cache MISSes through a single location close to your origin.

Previously, Smart Tiered Cache could not reliably select an optimal upper tier for origins behind anycast or regional unicast networks commonly used by cloud providers. Origins on AWS, GCP, Azure, and Oracle Cloud would fall back to a multi-upper-tier topology, resulting in lower cache HIT rates and more requests reaching your origin.

How it works

Set a cloud region hint (for example, aws/us-east-1 or gcp/europe-west1) for your origin IP or hostname. Smart Tiered Cache uses this hint along with real-time latency data to select a primary upper tier close to your cloud region, plus a fallback in a different location for resilience.

Supported providers: AWS, GCP, Azure, and Oracle Cloud.
All plans: Available on Free, Pro, Business, and Enterprise plans at no additional cost.
Dashboard and API: Configure from Caching > Tiered Cache > Origin Configuration, or use the API and Terraform.

Get started

To get started, enable Smart Tiered Cache and set a cloud region hint for your origin in the Tiered Cache settings.

Radar - AI Insights updates on Cloudflare Radar

Fri, 17 Apr 2026 00:00:00 GMT

Radar adds three new features to the AI Insights ↗ page, expanding visibility into how AI bots, crawlers, and agents interact with the web.

Adoption of AI agent standards

The AI Insights page now includes an adoption of AI agent standards ↗ widget that tracks how websites adopt agent-facing standards. The data is filterable by domain category and updated weekly on Mondays. This data is also available through the Agent Readiness API reference.

URL Scanner ↗ reports now include an Agent readiness tab that evaluates a scanned URL against the criteria used by the Agent Readiness score tool ↗.

For more details, refer to the Agent Readiness blog post ↗.

Markdown for Agents savings

A new savings gauge ↗ shows the median response-size reduction when serving Markdown instead of HTML to AI bots and crawlers. This highlights the bandwidth and token savings that Markdown for Agents provides.

For more details, refer to the Markdown for Agents API reference.

Response status

The new response status widget ↗ displays the distribution of HTTP response status codes returned to AI bots and crawlers. Results are groupable by individual status code (200, 403, 404) or by category (2xx, 3xx, 4xx, 5xx).

The same widget is available on each verified bot's detail page (only available for AI bots), for example Google ↗.

AI Search - AI Search instances now include built-in storage and namespace Workers Bindings

Thu, 16 Apr 2026 12:00:00 GMT

New AI Search instances created after today will work differently. New instances come with built-in storage and a vector index, so you can upload a file, have it indexed immediately, and search it right away.

Additionally new Workers Bindings are now available to use with AI Search. The new namespace binding lets you create and manage instances at runtime, and cross-instance search API lets you query across multiple instances in one call.

Built-in storage and vector index

All new instances now comes with built-in storage which allows you to upload files directly to it using the Items API or the dashboard. No R2 buckets to set up, no external data sources to connect first.

const instance = env.AI_SEARCH.get("my-instance");

// upload and wait for indexing to complete
const item = await instance.items.uploadAndPoll("faq.md", content);

// search immediately after indexing
const results = await instance.search({
	messages: [{ role: "user", content: "onboarding guide" }],
});

Namespace binding

The new ai_search_namespaces binding replaces the previous env.AI.autorag() API provided through the AI binding. It gives your Worker access to all instances within a namespace and lets you create, update, and delete instances at runtime without redeploying.

// wrangler.jsonc
{
	"ai_search_namespaces": [
		{
			"binding": "AI_SEARCH",
			"namespace": "default",
		},
	],
}

// create an instance at runtime
const instance = await env.AI_SEARCH.create({
	id: "my-instance",
});

For migration details, refer to Workers binding migration. For more on namespaces, refer to Namespaces.

Cross-instance search

Within the new AI Search binding, you now have access to a Search and Chat API on the namespace level. Pass an array of instance IDs and get one ranked list of results back.

const results = await env.AI_SEARCH.search({
	messages: [{ role: "user", content: "What is Cloudflare?" }],
	ai_search_options: {
		instance_ids: ["product-docs", "customer-abc123"],
	},
});

Refer to Namespace-level search for details.

AI Search - AI Search now has hybrid search and relevance boosting

Thu, 16 Apr 2026 12:00:00 GMT

AI Search now supports hybrid search and relevance boosting, giving you more control over how results are found and ranked.

Hybrid search

Hybrid search combines vector (semantic) search with BM25 keyword search in a single query. Vector search finds chunks with similar meaning, even when the exact words differ. Keyword search matches chunks that contain your query terms exactly. When you enable hybrid search, both run in parallel and the results are fused into a single ranked list.

You can configure the tokenizer (porter for natural language, trigram for code), keyword match mode (and for precision, or for recall), and fusion method (rrf or max) per instance:

const instance = await env.AI_SEARCH.create({
	id: "my-instance",
	index_method: { vector: true, keyword: true },
	fusion_method: "rrf",
	indexing_options: { keyword_tokenizer: "porter" },
	retrieval_options: { keyword_match_mode: "and" },
});

Refer to Search modes for an overview and Hybrid search for configuration details.

Relevance boosting

Relevance boosting lets you nudge search rankings based on document metadata. For example, you can prioritize recent documents by boosting on timestamp, or surface high-priority content by boosting on a custom metadata field like priority.

Configure up to 3 boost fields per instance or override them per request:

const results = await env.AI_SEARCH.get("my-instance").search({
	messages: [{ role: "user", content: "deployment guide" }],
	ai_search_options: {
		retrieval: {
			boost_by: [
				{ field: "timestamp", direction: "desc" },
				{ field: "priority", direction: "desc" },
			],
		},
	},
});

Refer to Relevance boosting for configuration details.

Artifacts - Artifacts now in beta: versioned filesystem with Git access

Thu, 16 Apr 2026 00:00:00 GMT

Artifacts is now in private beta. Artifacts is Git-compatible storage built for scale: create tens of millions of repos, fork from any remote, and hand off a URL to any Git client. It provides a versioned filesystem for storing and exchanging file trees across Workers, the REST API, and any Git client, running locally or within an agent.

You can read the announcement blog ↗ to learn more about what Artifacts does, how it works, and how to create repositories for your agents to use.

Artifacts has three API surfaces:

Workers bindings (for creating and managing repositories)
REST API (for creating and managing repos from any other compute platform)
Git protocol (for interacting with repos)

As an example: you can use the Workers binding to create a repo and read back its remote URL:

# Create a thousand, a million or ten million repos: one for every agent, for every upstream branch, or every user.
const created = await env.PROD_ARTIFACTS.create("agent-007");
const remote = (await created.repo.info())?.remote;

Or, use the REST API to create a repo inside a namespace from your agent(s) running on any platform:

curl --request POST "https://artifacts.cloudflare.net/v1/api/namespaces/some-namespace/repos" --header "Authorization: Bearer $CLOUDFLARE_API_TOKEN" --header "Content-Type: application/json" --data '{"name":"agent-007"}'

Any Git client that speaks smart HTTP can use the returned remote URL:

# Agents know git.
# Every repository can act as a git repo, allowing agents to interact with Artifacts the way they know best: using the git CLI.
git clone https://x:${REPO_TOKEN}@artifacts.cloudflare.net/some-namespace/agent-007.git

To learn more, refer to Get started, Workers binding, and Git protocol.

Email Service - Email Sending now in public beta

Thu, 16 Apr 2026 00:00:00 GMT

Email Sending is now in public beta. Send transactional emails directly from Workers (env.EMAIL.send()) or the REST API, with support for HTML, plain text, attachments, inline images, and custom headers. Email Sending joins Email Routing ↗ under the new Cloudflare Email Service — a single service for sending and receiving email on the Cloudflare developer platform.

Send an email from a Worker in a few lines of code:

src/index.jsjs

export default {
	async fetch(request, env) {
		const response = await env.EMAIL.send({
			from: "notifications@yourdomain.com",
			to: "user@example.com",
			subject: "Order confirmed",
			html: "<h1>Your order has been confirmed</h1>",
			text: "Your order has been confirmed.",
		});

		return Response.json({ messageId: response.messageId });
	},
};

src/index.tsts

export default {
	async fetch(request, env): Promise<Response> {
		const response = await env.EMAIL.send({
			from: "notifications@yourdomain.com",
			to: "user@example.com",
			subject: "Order confirmed",
			html: "<h1>Your order has been confirmed</h1>",
			text: "Your order has been confirmed.",
		});

		return Response.json({ messageId: response.messageId });
	},
} satisfies ExportedHandler<Env>;

Email Service also integrates with the Agents SDK, giving your agents a native onEmail hook to receive, process, and reply to emails. Combined with the new Email MCP server ↗ and Wrangler CLI email commands, any agent can send email regardless of where it runs.

Start sending and receiving emails from Workers and agents today. Email Sending is available on the Workers paid plan. Refer to the Email Service documentation to get started.

Workflows, Workers - Increased concurrency, creation rate, and queued instance limits for Workflows instances

Wed, 15 Apr 2026 13:00:00 GMT

Workflows limits have been raised to the following:

Limit	Previous	New
Concurrent instances (running in parallel)	10,000	50,000
Instance creation rate (per account)	100/second per account	300/second per account, 100/second per workflow
Queued instances per Workflow ¹	1 million	2 million

These increases apply to all users on the Workers Paid plan. Refer to the Workflows limits documentation for more details.

Queued instances are instances that have been created or awoken and are waiting for a concurrency slot. ↩

Browser Run - Browser Rendering is now Browser Run

Wed, 15 Apr 2026 12:00:00 GMT

We are renaming Browser Rendering to Browser Run. The name Browser Rendering never fully captured what the product does. Browser Run lets you run full browser sessions on Cloudflare's global network, drive them with code or AI, record and replay sessions, crawl pages for content, debug in real time, and let humans intervene when your agent needs help.

Along with the rename, we have increased limits for Workers Paid plans and redesigned the Browser Run dashboard.

We have 4x-ed concurrency limits for Workers Paid plan users:

Concurrent browsers per account: 30 → 120 per account
New browser instances: 30 per minute → 1 per second
REST API rate limits: recently increased from 3 to 10 requests per second

Rate limits across the limits page are now expressed in per-second terms, matching how they are enforced. No action is needed to benefit from the higher limits.

The redesigned dashboard ↗ now shows every request in a single Runs tab, not just browser sessions but also quick actions like screenshots, PDFs, markdown, and crawls. Filter by endpoint, view target URLs, status, and duration, and expand any row for more detail.

We are also shipping several new features:

Live View, Human in the Loop, and Session Recordings - See what your agent is doing in real time, let humans step in when automation hits a wall, and replay any session after it ends.
WebMCP - Websites can expose structured tools for AI agents to discover and call directly, replacing slow screenshot-analyze-click loops.

For the full story, read our Agents Week blog Browser Run: Give your agents a browser ↗.

Browser Run - Browser Run adds Live View, Human in the Loop, and Session Recordings

Wed, 15 Apr 2026 11:00:00 GMT

When browser automation fails or behaves unexpectedly, it can be hard to understand what happened. We are shipping three new features in Browser Run (formerly Browser Rendering) to help:

Live View for real-time visibility
Human in the Loop for human intervention
Session Recordings for replaying sessions after they end

Live View

Live View lets you see what your agent is doing in real time. The page, DOM, console, and network requests are all visible for any active browser session. Access Live View from the Cloudflare dashboard, via the hosted UI at live.browser.run, or using native Chrome DevTools.

Human in the Loop

When your agent hits a snag like a login page or unexpected edge case, it can hand off to a human instead of failing. With Human in the Loop, a human steps into the live browser session through Live View, resolves the issue, and hands control back to the script.

Today, you can step in by opening the Live View URL for any active session. Next, we are adding a handoff flow where the agent can signal that it needs help, notify a human to step in, then hand control back to the agent once the issue is resolved.

Session Recordings

Session Recordings records DOM state so you can replay any session after it ends. Enable recordings by passing recording: true when launching a browser. After the session closes, view the recording in the Cloudflare dashboard under Browser Run > Runs, or retrieve via API using the session ID. Next, we are adding the ability to inspect DOM state and console output at any point during the recording.

To get started, refer to the documentation for Live View, Human in the Loop, and Session Recording.

Browser Run - Browser Run adds WebMCP support

Wed, 15 Apr 2026 10:00:00 GMT

Browser Run (formerly Browser Rendering) now supports WebMCP ↗ (Web Model Context Protocol), a new browser API from the Google Chrome team.

The Internet was built for humans, so navigating as an AI agent today is unreliable. WebMCP lets websites expose structured tools for AI agents to discover and call directly. Instead of slow screenshot-analyze-click loops, agents can call website functions like searchFlights() or bookTicket() with typed parameters, making browser automation faster, more reliable, and less fragile.

With WebMCP, you can:

Discover website tools - Use navigator.modelContextTesting.listTools() to see available actions on any WebMCP-enabled site
Execute tools directly - Call navigator.modelContextTesting.executeTool() with typed parameters
Handle human-in-the-loop interactions - Some tools pause for user confirmation before completing sensitive actions

WebMCP requires Chrome beta features. We have an experimental pool with browser instances running Chrome beta so you can test emerging browser features before they reach stable Chrome. To start a WebMCP session, add lab=true to your /devtools/browser request:

curl -X POST "https://api.cloudflare.com/client/v4/accounts/{account_id}/browser-rendering/devtools/browser?lab=true&keep_alive=300000" \
  -H "Authorization: Bearer {api_token}"

Combined with the recently launched CDP endpoint, AI agents can also use WebMCP. Connect an MCP client to Browser Run via CDP, and your agent can discover and call website tools directly. Here's the same hotel booking demo, this time driven by an AI agent through OpenCode:

For a step-by-step guide, refer to the WebMCP documentation.

Access - Independent MFA for Access applications

Wed, 15 Apr 2026 00:00:00 GMT

Cloudflare Access now supports independent multi-factor authentication (MFA), allowing you to enforce MFA requirements without relying on your identity provider (IdP). With per-application and per-policy configuration, you can enforce stricter authentication methods like hardware security keys on sensitive applications without requiring them across your entire organization. This reduces the risk of MFA fatigue for your broader user population while adding additional security where it matters most.

This feature also addresses common gaps in IdP-based MFA, such as inconsistent MFA policies across different identity providers or the need for additional security layers beyond what the IdP provides.

Independent MFA supports the following authenticator types:

Authenticator application — Time-based one-time passwords (TOTP) using apps like Google Authenticator, Microsoft Authenticator, or Authy.
Security key — Hardware security keys such as YubiKeys.
Biometrics — Built-in device authenticators including Apple Touch ID, Apple Face ID, and Windows Hello.

Configuration levels

You can configure MFA requirements at three levels:

Level	Description
Organization	Enforce MFA by default for all applications in your account.
Application	Require or turn off MFA for a specific application.
Policy	Require or turn off MFA for users who match a specific policy.

Settings at lower levels (policy) override settings at higher levels (organization), giving you granular control over MFA enforcement.

User enrollment

Users enroll their authenticators through the App Launcher. To help with onboarding, administrators can share a direct enrollment link: <your-team-name>.cloudflareaccess.com/AddMfaDevice.

To get started with Independent MFA, refer to Independent MFA.

Agents - Agent Lee adds Write Operations and Generative UI

Wed, 15 Apr 2026 00:00:00 GMT

Agent Lee adds Write Operations and Generative UI

We are excited to announce two major capability upgrades for Agent Lee, the AI co-pilot built directly into the Cloudflare dashboard. Agent Lee is designed to understand your specific account configuration, and with this release, it moves from a passive advisor to an active assistant that can help you manage your infrastructure and visualize your data through natural language.

Take action with Write Operations

Agent Lee can now perform changes on your behalf across your Cloudflare account. Whether you need to update DNS records, modify SSL/TLS settings, or configure Workers routes, you can simply ask.

To ensure security and accuracy, every write operation requires explicit user approval. Before any change is committed, Agent Lee will present a summary of the proposed action in plain language. No action is taken until you select Confirm, and this approval requirement is enforced at the infrastructure level to prevent unauthorized changes.

Example requests:

"Add an A record for blog.example.com pointing to 192.0.2.10."
"Enable Always Use HTTPS on my zone."
"Set the SSL mode for example.com to Full (strict)."

Visualize data with Generative UI

Understanding your traffic and security trends is now as easy as asking a question. Agent Lee now features Generative UI, allowing it to render inline charts and structured data visualizations directly within the chat interface using your actual account telemetry.

Example requests:

"Show me a chart of my traffic over the last 7 days."
"What does my error rate look like for the past 24 hours?"
"Graph my cache hit rate for example.com this week."

Availability

These features are currently available in Beta for all users on the Free plan. To get started, log in to the Cloudflare dashboard ↗ and select Ask AI in the upper right corner.

To learn more about how to interact with your account using AI, refer to the Agent Lee documentation.

Cloudflare One - New, streamlined creation experience for Access Applications and Gateway Policies

Wed, 15 Apr 2026 00:00:00 GMT

The Cloudflare One dashboard now features redesigned builders for two core workflows: creating Gateway policies and configuring self-hosted Access applications.

Gateway rule builder

The Gateway rule builder now features a redesigned user experience, bringing it in line with the Access policy builder experience. Improvements include:

Streamlined UX with clearer states and improved user interactions
Wirefilter editing for viewing and editing Gateway rules directly from wirefilter expressions
Preview state to review the impact of your policy in a simple graphic

For more information, refer to Traffic policies.

Access application builder for self-hosted apps

The self-hosted Access application builder now offers a simplified creation workflow with fewer steps from setup to save. Improvements include:

New application selection experience that makes choosing the right application type before you begin easier.
Streamlined creation flow with fewer clicks to build and save an application
Inline policy creation for building Access policies directly within the application creation flow
Preview state to understand how your policies enforce user access before saving

For more information, refer to self-hosted applications.

Digital Experience Monitoring - Last seen timestamp for Cloudflare One Client devices is more consistent

Wed, 15 Apr 2026 00:00:00 GMT

The last seen timestamp for Cloudflare One Client devices is now more consistent across the dashboard. IT teams will see more consistent information about the most recent client event between a device and Cloudflare's network.

Logs - New TenantID and Firewall for AI fields in Logpush datasets

Wed, 15 Apr 2026 00:00:00 GMT

Cloudflare has added new fields to multiple Logpush datasets:

TenantID field

The following Gateway and Zero Trust datasets now include a TenantID field:

Gateway DNS: Identifies the tenant ID of the DNS request, if it exists.
Gateway HTTP: Identifies the tenant ID of the HTTP request, if it exists.
Gateway Network: Identifies the tenant ID of the network session, if it exists.
Zero Trust Network Sessions: Identifies the tenant ID of the network session, if it exists.

Firewall for AI fields

The following datasets now include Firewall for AI fields:

Firewall Events:
- FirewallForAIInjectionScore: The score indicating the likelihood of a prompt injection attack in the request.
- FirewallForAIPIICategories: List of PII categories detected in the request.
- FirewallForAITokenCount: The number of tokens in the request.
- FirewallForAIUnsafeTopicCategories: List of unsafe topic categories detected in the request.
HTTP Requests:
- FirewallForAIInjectionScore: The score indicating the likelihood of a prompt injection attack in the request.
- FirewallForAIPIICategories: List of PII categories detected in the request.
- FirewallForAITokenCount: The number of tokens in the request.
- FirewallForAIUnsafeTopicCategories: List of unsafe topic categories detected in the request.

For the complete field definitions for each dataset, refer to Logpush datasets.

Privacy Proxy - Privacy Proxy metrics now available via GraphQL Analytics API

Wed, 15 Apr 2026 00:00:00 GMT

Privacy Proxy metrics are now queryable through Cloudflare's GraphQL Analytics API, the new default method for accessing Privacy Proxy observability data. All metrics are available through a single endpoint:

curl https://api.cloudflare.com/client/v4/graphql \
  --header "Authorization: Bearer <API_TOKEN>" \
  --header "Content-Type: application/json" \
  --data '{
    "query": "{ viewer { accounts(filter: { accountTag: $accountTag }) { privacyProxyRequestMetricsAdaptiveGroups(filter: { date_geq: $startDate, date_leq: $endDate }, limit: 10000, orderBy: [date_ASC]) { count dimensions { date } } } } }",
    "variables": {
      "accountTag": "<YOUR_ACCOUNT_TAG>",
      "startDate": "2026-04-04",
      "endDate": "2026-04-06"
    }
  }'

Available nodes

Four GraphQL nodes are now live, providing aggregate metrics across all key dimensions of your Privacy Proxy deployment:

privacyProxyRequestMetricsAdaptiveGroups — Request volume, error rates, status codes, and proxy status breakdowns.
privacyProxyIngressConnMetricsAdaptiveGroups — Client-to-proxy connection counts, bytes transferred, and latency percentiles.
privacyProxyEgressConnMetricsAdaptiveGroups — Proxy-to-origin connection counts, bytes transferred, and latency percentiles.
privacyProxyAuthMetricsAdaptiveGroups — Authentication attempt counts by method and result.

All nodes support filtering by time, data center (coloCode), and endpoint, with additional node-specific dimensions such as transport protocol and authentication method.

What this means for existing OpenTelemetry users

OpenTelemetry-based metrics export remains available. The GraphQL Analytics API is now the recommended default method — a plug-and-play method that requires no collector infrastructure, saving engineering overhead.

WAF - WAF Release - 2026-04-15

Wed, 15 Apr 2026 00:00:00 GMT

This week's release introduces a new detection for a critical Remote Code Execution (RCE) vulnerability in Mesop (CVE-2026-33057), alongside protections for high-impact vulnerabilities in Cisco Secure Firewall Management Center (CVE-2026-20079) and FortiClient EMS (CVE-2026-21643). Additionally, this release includes an update to our existing React Server DoS coverage to address recently identified resource exhaustion vectors (CVE-2026-23869).

Key Findings

Cisco Secure FMC (CVE-2026-20079): A vulnerability in the web-based management interface of Cisco Secure Firewall Management Center (FMC) that allows an unauthenticated, remote attacker to execute arbitrary commands or bypass security filters.
FortiClient EMS (CVE-2026-21643): A critical vulnerability in the FortiClient EMS permitting unauthorized access or administrative configuration manipulation via crafted HTTP requests.
Mesop (CVE-2026-33057): A vulnerability in the Mesop Python-based UI framework where unauthenticated attackers can execute arbitrary code by sending specially crafted, Base64-encoded payloads in the request body.

Impact

Successful exploitation of these vulnerabilities could allow unauthenticated attackers to execute arbitrary code, gain administrative control over network management infrastructure, or trigger server-side resource exhaustion. Administrators are strongly encouraged to apply official vendor updates.

Data Loss Prevention - DLP account-level settings

Tue, 14 Apr 2026 12:00:00 GMT

Account-level DLP settings are now available in Cloudflare One. You can now configure advanced DLP settings at the account level, including OCR, AI context analysis, and payload masking. This provides consistent enforcement across all DLP profiles and simplifies configuration management.

Key changes:

Consistent enforcement: Settings configured at the account level apply to all DLP profiles
Simplified migration: Settings enabled on any profile are automatically migrated to account level
Deprecation notice: Profile-level advanced settings will be deprecated in a future release

Migration details:

During the migration period, if a setting is enabled on any profile, it will automatically be enabled at the account level. This means profiles that previously had a setting disabled may now have it enabled if another profile in the account had it enabled.

Settings are evaluated using OR logic - a setting is enabled if it is turned on at either the account level or the profile level. However, profile-level settings cannot be enabled when the account-level setting is off.

For more details, refer to the DLP settings documentation.

Browser Run - Manage Browser Rendering sessions with Wrangler CLI

Tue, 14 Apr 2026 00:00:00 GMT

Browser Rendering now supports wrangler browser commands, letting you create, manage, and view browser sessions directly from your terminal, streamlining your workflow. Since Wrangler handles authentication, you do not need to pass API tokens in your commands.

The following commands are available:

Command	Description
`wrangler browser create`	Create a new browser session
`wrangler browser close`	Close a session
`wrangler browser list`	List active sessions
`wrangler browser view`	View a live browser session

The create command spins up a browser instance on Cloudflare's network and returns a session URL. Once created, you can connect to the session using any CDP-compatible client like Puppeteer, Playwright, or MCP clients to automate browsing, scrape content, or debug remotely.

wrangler browser create

Use --keepAlive to set the session keep-alive duration (60-600 seconds):

wrangler browser create --keepAlive 300

The view command auto-selects when only one session exists, or prompts for selection when multiple sessions are available.

All commands support --json for structured output, and because these are CLI commands, you can incorporate them into scripts to automate session management.

For full usage details, refer to the Wrangler commands documentation.

Cloudflare One - Introducing Cloudflare Mesh

Tue, 14 Apr 2026 00:00:00 GMT

Cloudflare Mesh is now available (blog post ↗). Mesh connects your services and devices with post-quantum encrypted networking, allowing you to route traffic privately between servers, laptops, and phones over TCP, UDP, and ICMP.

What Cloudflare Mesh does

Assigns a private Mesh IP to every enrolled device and node.
Enables any participant to reach any other participant by IP — including client-to-client, without deploying any infrastructure.
Supports CIDR routes for subnet routing through Mesh nodes.
Supports high availability with active-passive replicas for nodes with routes.
All traffic flows through Cloudflare, so Gateway network policies, device posture checks, and access rules apply to every connection.

What changed

WARP Connector is now Cloudflare Mesh. Existing WARP Connectors are now called mesh nodes. All existing deployments continue to work — no migration required.
Peer-to-peer connectivity is now called Mesh connectivity and is part of the Cloudflare Mesh documentation.
Mesh node limit increased from 10 to 50 per account.
New dashboard experience ↗ at Networking > Mesh with an interactive network map, node management, route configuration, diagnostics, and a setup wizard.

Get started

Refer to the Cloudflare Mesh documentation to set up your first Mesh network.

Data Loss Prevention - Detect Cloudflare API tokens with DLP

Tue, 14 Apr 2026 00:00:00 GMT

The Credentials and Secrets DLP profile now includes three new predefined entries for detecting Cloudflare API credentials:

Entry name	Token prefix	Detects
Cloudflare User API Key	`cfk_`	User-scoped API keys
Cloudflare User API Token	`cfut_`	User-scoped API tokens
Cloudflare Account Owned API Token	`cfat_`	Account-scoped API tokens

These detections target the new Cloudflare API credential format, which uses a structured prefix and a CRC32 checksum suffix. The identifiable prefix makes it possible to detect leaked credentials with high confidence and low false positive rates — no surrounding context such as Authorization: Bearer headers is required.

Credentials generated before this format change will not be matched by these entries.

How to enable Cloudflare API token detections

In the Cloudflare dashboard ↗, go to Zero Trust > DLP > DLP Profiles.
Select the Credentials and Secrets profile.
Turn on one or more of the new Cloudflare API token entries.
Use the profile in a Gateway HTTP policy to log or block traffic containing these credentials.

Example policy:

Selector	Operator	Value	Action
DLP Profile	in	Credentials and Secrets	Block

You can also enable individual entries to scope detection to specific credential types — for example, enabling Account Owned API Token detection without enabling User API Key detection.

For more information, refer to predefined DLP profiles.

Gateway, Data Loss Prevention - Configure how sensitive data appears in DLP payload logs

Tue, 14 Apr 2026 00:00:00 GMT

You can now configure how sensitive data matches are displayed in your DLP payload match logs — giving your incident response team the context they need to validate alerts without compromising your security posture.

To get started, go to the Cloudflare dashboard ↗, select Zero Trust > Data loss prevention > DLP settings and find the Payload log masking card.

Previously, all DLP payload logs used a single masking mode that obscured matched data entirely and hid the original character count, making it difficult to distinguish true positives from false positives. This update introduces three options:

Full Mask (default): Masks the match while preserving character count and visual formatting (for example, ***-**-**** for a Social Security Number). This is an improvement over the previous default, which did not preserve character count.
Partial Mask: Reveals 25% of the matched content while masking the remainder (for example, ***-**-6789).
Clear Text: Stores the full, unmasked violation for deep investigation (for example, 123-45-6789).

Important: The masking level you select is applied at detection time, before the payload is encrypted. This means the chosen format is what your team will see after decrypting the log with your private key — the existing encryption workflow is unchanged.

Applies to all enabled detections: When a masking level other than Full Mask is selected, it applies to all sensitive data matches found within a payload window — not just the match that triggered the policy. Any data matched by your enabled DLP detection entries will be masked at the selected level.

For more information, refer to DLP logging options.

Cloudflare Fundamentals - Improved OAuth experience for consent and management

Tue, 14 Apr 2026 00:00:00 GMT

OAuth allows third-party applications to access your Cloudflare account on your behalf — like when Wrangler deploys Workers or when monitoring tools read your analytics. You now have granular control over which accounts these applications can access, plus the ability to revoke access anytime.

What's new

Choose which accounts to authorize

When authorizing an OAuth application, you can now select specific accounts instead of granting access to all your accounts:

Account-by-account selection — Choose exactly which accounts the application can access
"All accounts" option — Still available for trusted tools like Wrangler This gives you precise control who can access your data.

The OAuth consent screen now shows:

What the application can access — Explicit list of permissions being requested
Who created the application — Application owner and contact information
Which accounts you're authorizing — Checkboxes for account selection

WAF - Email obfuscation decode script is now non-render-blocking

Tue, 14 Apr 2026 00:00:00 GMT

The decode script injected by Email Address Obfuscation now loads with the defer attribute. This means the script no longer blocks page rendering. It downloads in parallel with HTML parsing and executes after the document is fully parsed, before the DOMContentLoaded event.

This improves page loading performance, contributing to better Core Web Vitals, for all zones with Email Address Obfuscation on. No action is required.

If you have custom JavaScript that depends on email addresses being decoded at a specific point during page load, note that the decode script now executes after HTML parsing completes rather than inline during parsing.

Workers VPC - VPC Networks and Cloudflare Mesh support now in public beta

Tue, 14 Apr 2026 00:00:00 GMT

VPC Network bindings now give your Workers access to any service in your private network without pre-registering individual hosts or ports. This complements existing VPC Service bindings, which scope each binding to a specific host and port.

You can bind to a Cloudflare Tunnel by tunnel_id to reach any service on the network where that tunnel is running, or bind to your Cloudflare Mesh network using cf1:network to reach any Mesh node, client device, or subnet route in your account:

{
  "vpc_networks": [
    {
      "binding": "MESH",
      "network_id": "cf1:network",
      "remote": true
    }
  ]
}

[[vpc_networks]]
binding = "MESH"
network_id = "cf1:network"
remote = true

At runtime, fetch() routes through the network to reach the service at the IP and port you specify:

const response = await env.MESH.fetch("http://10.0.1.50:8080/api/data");

For configuration options and examples, refer to VPC Networks and Connect Workers to Cloudflare Mesh.

Containers - Containers and Sandboxes are now generally available

Mon, 13 Apr 2026 00:00:00 GMT

Cloudflare Containers and Sandboxes are now generally available.

Containers let you run more workloads on the Workers platform, including resource-intensive applications, different languages, and CLI tools that need full Linux environments.

Since the initial launch of Containers, there have been significant improvements to Containers' performance, stability, and feature set. Some highlights include:

Higher limits allow you to run thousands of containers concurrently.
Active-CPU pricing means that you only pay for used CPU cycles.
Easy connections to Workers and other bindings via hostnames help you extend your Containers with additional functionality.
Docker Hub support makes it easy to use your existing images and registries.
SSH support helps you access and debug issues in live containers.

The Sandbox SDK provides isolated environments for running untrusted code securely, with a simple TypeScript API for executing commands, managing files, and exposing services. This makes it easier to secure and manage your agents at scale. Some additions since launch include:

Live preview URLs so agents can run long-lived services and verify in-flight changes.
Persistent code interpreters for Python, JavaScript, and TypeScript, with rich structured outputs.
Interactive PTY terminals for real browser-based terminal access with multiple isolated shells per sandbox.
Backup and restore APIs to snapshot a workspace and quickly restore an agent's coding session without repeating expensive setup steps.
Real-time filesystem watching so apps and agents can react immediately to file changes inside a sandbox.

For more information, refer to Containers and Sandbox SDK documentation.

Containers, Agents - Secure credential injection and dynamic egress policies for Sandboxes

Mon, 13 Apr 2026 00:00:00 GMT

Outbound Workers for Sandboxes and Containers now support zero-trust credential injection, TLS interception, allow/deny lists, and dynamic per-instance egress policies. These features give platforms running agentic workloads full control over what leaves the sandbox, without exposing secrets to untrusted workloads, like user-generated code or coding agents.

Credential injection

Because outbound handlers run in the Workers runtime, outside the sandbox, they can hold secrets the sandbox never sees. A sandboxed workload can make a plain request, and credentials are transparently attached before a request is forwarded upstream.

For instance, you could run an agent in a sandbox and ensure that any requests it makes to Github are authenticated. But it will never be able to access the credentials:

export class MySandbox extends Sandbox {}

MySandbox.outboundByHost = {
	"github.com": (request: Request, env: Env, ctx: OutboundHandlerContext) => {
		const requestWithAuth = new Request(request);
		requestWithAuth.headers.set("x-auth-token", env.SECRET);
		return fetch(requestWithAuth);
	},
};

You can easily inject unique credentials for different instances by using ctx.containerId:

MySandbox.outboundByHost = {
	"my-internal-vcs.dev": async (
		request: Request,
		env: Env,
		ctx: OutboundHandlerContext,
	) => {
		const authKey = await env.KEYS.get(ctx.containerId);

		const requestWithAuth = new Request(request);
		requestWithAuth.headers.set("x-auth-token", authKey);
		return fetch(requestWithAuth);
	},
};

No token is ever passed into the sandbox. You can rotate secrets in the Worker environment and every request will pick them up immediately.

TLS interception

Outbound Workers now intercept HTTPS traffic. A unique ephemeral certificate authority (CA) and private key are created for each sandbox instance. The CA is placed into the sandbox and trusted by default. The ephemeral private key never leaves the container runtime sidecar process and is never shared across instances.

With TLS interception active, outbound Workers can act as a transparent proxy for both HTTP and HTTPS traffic.

Allow and deny hosts

Easily filter outbound traffic with allowedHosts and deniedHosts. When allowedHosts is set, it becomes a deny-by-default allowlist. Both properties support glob patterns.

export class MySandbox extends Sandbox {
	allowedHosts = ["github.com", "npmjs.org"];
}

Dynamic outbound handlers

Define named outbound handlers then apply or remove them at runtime using setOutboundHandler() or setOutboundByHost(). This lets you change egress policy for a running sandbox without restarting it.

export class MySandbox extends Sandbox {}

MySandbox.outboundHandlers = {
	allowHosts: async (req: Request, env: Env, ctx: OutboundHandlerContext ) => {
		const url = new URL(req.url);
		if (ctx.params.allowedHostnames.includes(url.hostname)) {
			return fetch(req);
		}
		return new Response(null, { status: 403 });
	},

	noHttp: async () => {
		return new Response(null, { status: 403 });
	},
};

Apply handlers programmatically from your Worker:

const sandbox = getSandbox(env.Sandbox, userId);

// Open network for setup
await sandbox.setOutboundHandler("allowHosts", {
	allowedHostnames: ["github.com", "npmjs.org"],
});
await sandbox.exec("npm install");

// Lock down after setup
await sandbox.setOutboundHandler("noHttp");

Handlers accept params, so you can customize behavior per instance without defining separate handler functions.

Get started

Upgrade to @cloudflare/containers@0.3.0 or @cloudflare/sandbox@0.8.9 to use these features.

For more details, refer to Sandbox outbound traffic and Container outbound traffic.

Workers - Local Explorer for local resource data

Mon, 13 Apr 2026 00:00:00 GMT

Local Explorer is a browser-based interface and REST API for viewing and editing local resource data during development. It removes the need to write throwaway scripts or dig through .wrangler/state to understand what data your Worker has stored locally.

Local Explorer is available in Wrangler 4.82.1+ and the Cloudflare Vite plugin 1.32.0+. Start a local development session and press e in your terminal, or navigate to /cdn-cgi/explorer on your local dev server.

Supported resources

Local Explorer supports five resource types and works across multiple workers running locally:

KV — Browse keys, view values and metadata, create, update, and delete key-value pairs.
R2 — List objects, view metadata, upload files, and delete objects. Supports directory views and multi-select.
D1 — Browse tables and rows, run arbitrary SQL queries, and edit schemas in a full data studio.
Durable Objects (SQLite storage) — Browse individual object SQLite tables, run SQL queries, and edit schemas.
Workflows — List instances, view status and step history, trigger new runs, and pause, resume, restart, or terminate instances.

OpenAPI-powered REST API

Local Explorer exposes a REST API at /cdn-cgi/explorer/api that provides programmatic access to the same operations available in the browser. The root endpoint returns an OpenAPI specification ↗ describing all available endpoints, parameters, and response formats.

curl http://localhost:8787/cdn-cgi/explorer/api

Point an AI coding agent at /cdn-cgi/explorer/api and it can discover and interact with your local resources without manual setup. This enables iterative development loops where an agent can populate test data in KV or D1, inspect Durable Object state, trigger Workflow runs, or upload files to R2.

For more details, refer to the Local Explorer documentation.

Browser Isolation - Canvas Remoting optimizes performance for productivity applications

Fri, 10 Apr 2026 00:00:00 GMT

Remote Browser Isolation now supports Canvas Remoting, improving performance for HTML5 Canvas applications by sending vector draw commands instead of rasterized bitmaps.

Key improvements

10x bandwidth reduction: Microsoft Word and other Office apps use 90% less bandwidth
Smooth performance: Google Sheets maintains consistent 30fps rendering
Responsive terminals: Web-based development environments and AI notebooks work in real-time
Zero configuration: Enabled by default for all Browser Isolation customers

How it works

Instead of sending rasterized bitmaps for every Canvas update, Browser Isolation now:

Captures Canvas draw commands at the source
Converts them to lightweight vector instructions
Renders Canvas content on the client

This reduces bandwidth from hundreds of kilobytes per second to tens of kilobytes per second.

Managing Canvas Remoting

To temporarily disable for troubleshooting:

Right-click the isolated webpage background
Select Disable Canvas Remoting
Re-enable the same way by selecting Enable Canvas Remoting

Limitations

Currently supports 2D Canvas contexts only. WebGL and 3D graphics applications continue using bitmap rendering. For more information, refer to Canvas Remoting.

Browser Run - Browser Rendering adds Chrome DevTools Protocol (CDP) and MCP client support

Fri, 10 Apr 2026 00:00:00 GMT

Browser Rendering now exposes the Chrome DevTools Protocol (CDP), the low-level protocol that powers browser automation. The growing ecosystem of CDP-based agent tools, along with existing CDP automation scripts, can now use Browser Rendering directly.

Any CDP-compatible client, including Puppeteer and Playwright, can connect from any environment, whether that is Cloudflare Workers, your local machine, or a cloud environment. All you need is your Cloudflare API key.

For any existing CDP script, switching to Browser Rendering is a one-line change:

const puppeteer = require("puppeteer-core");

const browser = await puppeteer.connect({
	browserWSEndpoint: `wss://api.cloudflare.com/client/v4/accounts/${ACCOUNT_ID}/browser-rendering/devtools/browser?keep_alive=600000`,
	headers: { Authorization: `Bearer ${API_TOKEN}` },
});

const page = await browser.newPage();
await page.goto("https://example.com");
console.log(await page.title());
await browser.close();

Additionally, MCP clients like Claude Desktop, Claude Code, Cursor, and OpenCode can now use Browser Rendering as their remote browser via the chrome-devtools-mcp ↗ package.

Here is an example of how to configure Browser Rendering for Claude Desktop:

{
	"mcpServers": {
		"browser-rendering": {
			"command": "npx",
			"args": [
				"-y",
				"chrome-devtools-mcp@latest",
				"--wsEndpoint=wss://api.cloudflare.com/client/v4/accounts/<ACCOUNT_ID>/browser-rendering/devtools/browser?keep_alive=600000",
				"--wsHeaders={\"Authorization\":\"Bearer <API_TOKEN>\"}"
			]
		}
	}
}

To get started, refer to the CDP documentation.

Cloudflare Fundamentals - API tokens now detectable by secret scanning tools

Fri, 10 Apr 2026 00:00:00 GMT

Cloudflare API tokens now include identifiable patterns that enable secret scanning tools to automatically detect them when leaked in code repositories, configuration files, or other public locations.

What changed

API tokens generated by Cloudflare now follow a standardized format that secret scanning tools can recognize. When a Cloudflare token is accidentally committed to GitHub, GitLab, or another platform with secret scanning enabled, the tool will flag it and alert you.

Why this matters

Leaked credentials are a common security risk. By making Cloudflare tokens detectable by scanning tools, you can:

Detect leaks faster — Get notified immediately when a token is exposed.
Reduce risk window — Exposed tokens are deactivated immediately, before they can be exploited.
Automate security — Leverage existing secret scanning infrastructure without additional configuration.

What happens when a leak is detected

When a third-party secret scanning tool detects a leaked Cloudflare API token:

Cloudflare immediately deactivates the token to prevent unauthorized access.
The token creator receives an email notification alerting them to the leak.
The token is marked as "Exposed" in the Cloudflare dashboard.
You can then roll or delete the token from the token management pages.

Supported platforms

GitHub Secret Scanning — Automatically enabled for public repositories

For more information on token formats and secret scanning, refer to API token formats.

CASB - Send CASB posture finding instances with webhooks

Thu, 09 Apr 2026 00:00:00 GMT

You can now use CASB webhooks in Cloudflare One to send posture finding instances to external systems such as chat platforms, ticketing systems, SIEMs, SOAR tools, and custom automation services.

This gives security teams a simple way to route CASB posture findings into the tools and workflows they already use for triage and response.

To get started, go to Integrations > Webhooks in the Cloudflare One dashboard to create a webhook destination. After you configure a webhook, open a posture finding instance and select Send webhook to send it.

Key capabilities

Flexible authentication — Configure destinations using None, Basic Auth, Bearer Auth, Static Headers, or HMAC-Signing.
Built-in testing — Use Test delivery to send a test request before sending a live finding instance.
Posture finding workflows — Send posture finding instances directly from the finding details workflow in Cloud & SaaS findings.
HTTPS destinations — Configure webhook destinations with public https:// URLs.

Workers - Relaxed simultaneous connection limiting for Workers

Thu, 09 Apr 2026 00:00:00 GMT

The simultaneous open connections limit has been relaxed. Previously, each Worker invocation was limited to six open connections at a time for the entire lifetime of each connection, including while reading the response body. Now, a connection is freed as soon as response headers arrive, so the six-connection limit only constrains how many connections can be in the initial "waiting for headers" phase simultaneously.

Before: New connections are blocked until an earlier connection fully completes

After: New connections can start as soon as response headers arrive

This means Workers can now have many more connections open at the same time without queueing, as long as no more than six are waiting for their initial response. This eliminates the Response closed due to connection limit exception that could previously occur when the runtime canceled stalled connections to prevent deadlocks.

Previously, the runtime used a deadlock avoidance algorithm that watched each open connection for I/O activity. If all six connections appeared idle — even momentarily — the runtime would cancel the least-recently-used connection to make room for new requests. In practice, this heuristic was fragile. For example, when a response used Content-Encoding: gzip, the runtime's internal decompression created brief gaps between read and write operations. During these gaps, the connection appeared stalled despite being actively read by the Worker. If multiple connections hit these gaps at the same time, the runtime could spuriously cancel a connection that was working correctly. By only counting connections during the waiting-for-headers phase — where the runtime is fully in control and there is no ambiguity about whether the connection is active — this class of bug is eliminated entirely.

Before: Connections could be canceled during brief internal pauses

After: Connections complete normally regardless of internal pauses

AI Search - Website Source CSS content selectors for precise content extraction in AI Search

Wed, 08 Apr 2026 00:00:00 GMT

AI Search now supports CSS content selectors for website data sources. You can now define which parts of a crawled page are extracted and indexed by specifying CSS selectors paired with URL glob patterns.

Content selectors solve the problem of indexing only relevant content while ignoring navigation, sidebars, footers, and other boilerplate. When a page URL matches a glob pattern, only elements matching the corresponding CSS selector are extracted and converted to Markdown for indexing.

Configure content selectors via the dashboard or API:

curl "https://api.cloudflare.com/client/v4/accounts/{account_id}/ai-search/instances" \
  -H "Authorization: Bearer {api_token}" \
  -H "Content-Type: application/json" \
  -d '{
    "id": "my-ai-search",
    "source": "https://example.com",
    "type": "web-crawler",
    "source_params": {
      "web_crawler": {
        "parse_options": {
          "content_selector": [
            {
              "path": "**/blog/**",
              "selector": "article .post-body"
            }
          ]
        }
      }
    }
  }'

Selectors are evaluated in order, and the first matching pattern wins. You can define up to 10 content selector entries per instance.

For configuration details and examples, refer to the content selectors documentation.

AI Search - New Workers AI models for text generation and embedding in AI Search

Wed, 08 Apr 2026 00:00:00 GMT

AI Search now supports four additional Workers AI models across text generation and embedding.

Text generation

Model	Context window (tokens)
`@cf/zai-org/glm-4.7-flash`	131,072
`@cf/qwen/qwen3-30b-a3b-fp8`	32,000

GLM-4.7-Flash is a lightweight model from Zhipu AI with a 131,072 token context window, suitable for long-document summarization and retrieval tasks. Qwen3-30B-A3B is a mixture-of-experts model from Alibaba that activates only 3 billion parameters per forward pass, keeping inference fast while maintaining strong response quality.

Embedding

Model	Vector dims	Input tokens	Metric
`@cf/qwen/qwen3-embedding-0.6b`	1,024	4,096	cosine
`@cf/google/embeddinggemma-300m`	768	512	cosine

Qwen3-Embedding-0.6B supports up to 4,096 input tokens, making it a good fit for indexing longer text chunks. EmbeddingGemma-300M from Google produces 768-dimension vectors and is optimized for low-latency embedding workloads.

All four models are available without additional provider keys since they run on Workers AI. Select them when creating or updating an AI Search instance in the dashboard or through the API.

For the full list of supported models, refer to Supported models.

Risk Score - User risk scoring for high risk browsing activity

Wed, 08 Apr 2026 00:00:00 GMT

Cloudflare One's User Risk Scoring now incorporates direct signals from Gateway DNS traffic patterns. This update allows security teams to automatically elevate a user's risk score when they visit high-risk or malicious domains, providing a more holistic view of internal threats.

Why this matters

Browsing activity is a primary indicator of potential compromise. By tying Gateway DNS logs to specific users, administrators can now flag individuals interacting with:

Security threats: Domains associated with malware, phishing, or command-and-control (C2) centers.
High-risk content: Categories such as questionable content or violence that may violate corporate compliance.

Even if a Gateway policy is set to Block the traffic, the interaction is still captured as a "hit" to ensure the user's risk profile reflects the attempted activity.

New risk behaviors

Two new behaviors are now available in the dashboard:

Suspicious Security Domain Visited: Triggers when a user visits a domain in the security threats or security risk categories.
High risk domain visited: Triggers when a user visits domains categorized as questionable content, violence, or CIPA.

To learn more and get started, refer to the User Risk Scoring documentation.

Security Center - Real-time alerts and daily digests for Threat Events

Wed, 08 Apr 2026 00:00:00 GMT

You can now automate your threat monitoring by setting up custom alerts in your saved views. Instead of manually checking the dashboard for updates, you can subscribe to notifications that trigger whenever new data matches your specific filter sets, like new activity associated to a particular threat actor or spikes in activity within your industry.

Stay ahead of emerging threats

By linking your saved views to the Cloudflare Notifications Center, you can ensure the right information reaches your team at the right time.

Immediate Alerts: receive real-time notifications the moment a critical event is detected that matches your saved criteria. This is essential for high-priority monitoring, such as tracking active campaigns from specific APT groups.
Daily Digests: opt for a summarized report delivered once a day. This is ideal for maintaining situational awareness of broader trends, like regional activity shifts or industry-wide threat landscapes, without cluttering your inbox.

How to get started

To set up an alert, go to Application Security > Threat Intelligence > Threat Events. From there:

Choose your datasets and apply your desired filters and select Save View (or select an existing one).
Open the Manage Saved Views menu.
Select Add Alert next to your chosen view to configure your notification preferences in the Cloudflare dashboard.

For more technical details on configuring notifications, refer to the Threat Events documentation.

Cloudflare One Client - Cloudflare One Client for Windows (version 2026.3.851.0)

Tue, 07 Apr 2026 15:56:36 GMT

A new GA release for the Windows Cloudflare One Client is now available on the stable releases downloads page.

This release contains minor fixes and improvements.

The next stable release for Windows will introduce the new Cloudflare One Client UI, providing a cleaner and more intuitive design as well as easier access to common actions and information.

Changes and improvements

Fixed an issue causing Windows client tunnel interface initialization failure which prevented clients from establishing a tunnel for connection.
Consumer-only CLI commands are now clearly distinguished from Zero Trust commands.
Added detailed QUIC connection metrics to diagnostic logs for better troubleshooting.
Added monitoring for tunnel statistics collection timeouts.
Switched tunnel congestion control algorithm for local proxy mode to Cubic for improved reliability across platforms.
Fixed packet capture failing on tunnel interface when the tunnel interface is renamed by SCCM VPN boundary support.
Fixed unnecessary registration deletion caused by RDP connections in multi-user mode.
Fixed increased tunnel interface start-up time due to a race between duplicate address detection (DAD) and disabling NetBT.
Fixed tunnel failing to connect when the system DNS search list contains unexpected characters.
Empty MDM files are now rejected instead of being incorrectly accepted as a single MDM config.
Fixed an issue in local proxy mode where the client could become unresponsive due to upstream connection timeouts.
Fixed an issue where the emergency disconnect status of a prior organization persisted after a switch to a different organization.
Fixed initiating managed network detections checks when no network is available, which caused device profile flapping.
Fixed an issue where degraded Windows Management Instrumentation (WMI) state could put the client in a failed connection state loop during initialization.

Known issues

For Windows 11 24H2 users, Microsoft has confirmed a regression that may lead to performance issues like mouse lag, audio cracking, or other slowdowns. Cloudflare recommends users experiencing these issues upgrade to a minimum Windows 11 24H2 version KB5062553 or higher for resolution. This warning will be omitted from future release notes. This Windows update was released in July 2025.
Devices with KB5055523 installed may receive a warning about Win32/ClickFix.ABA being present in the installer. To resolve this false positive, update Microsoft Security Intelligence to version 1.429.19.0 or later. This warning will be omitted from future release notes. This Microsoft Security Intelligence update was released in May 2025.
DNS resolution may be broken when the following conditions are all true:
- The client is in Secure Web Gateway without DNS filtering (tunnel-only) mode.
- A custom DNS server address is configured on the primary network adapter.
- The custom DNS server address on the primary network adapter is changed while the client is connected.
To work around this issue, reconnect the client by selecting Disconnect and then Connect in the client user interface.

Email security - User Submission Triage Status Tracking

Tue, 07 Apr 2026 09:00:00 GMT

Cloudflare Email security now supports Triage Status Tracking for User Submissions. This enhancement gives SOC teams a streamlined way to track, manage, and prioritize user-submitted emails directly within the Cloudflare One dashboard.

The User Submissions table now includes a Status column with three states: Unreviewed (new submissions awaiting triage), Reviewed (submissions assessed by the SOC team), and Escalated (submissions escalated to team submissions for further investigation). Analysts can quickly update statuses and filter the table to focus on what needs attention.
SOC teams can now organize their triage workflows, avoid duplicate reviews, and make sure critical threats get escalated for deeper investigation—bringing order to the chaos of high-volume submission management.

Triage Status Tracking is automatically available for all Email security customers using the user submissions feature. No additional configuration is required; customers just need to make sure user submissions are being sent to their user submission aliases.

This applies to all Email security packages:

Advantage
Enterprise
Enterprise + PhishGuard

Cloudflare One Appliance, Cloudflare One, Cloudflare WAN - Link aggregation (LACP) support for Cloudflare One Appliance

Tue, 07 Apr 2026 00:00:00 GMT

Cloudflare One Appliance now supports Link Aggregation Control Protocol (LACP), allowing you to bundle up to six physical LAN ports into a single logical interface. Link aggregation increases available bandwidth and eliminates single points of failure on the LAN side of the appliance.

This feature is available in beta on physical appliance hardware with the latest OS. No entitlement is required.

To configure a Link Aggregation Group, refer to Configure link aggregation groups.

SSL/TLS - Manage mTLS and BYO CA certificates from the Cloudflare dashboard

Tue, 07 Apr 2026 00:00:00 GMT

You can now manage mutual TLS (mTLS) and Bring Your Own Certificate Authority (BYO CA) configurations directly from the Cloudflare dashboard — no API required.

Previously, these advanced workflows required the Cloudflare API. The following are now available in the dashboard:

AOP certificate management — Upload and manage your own certificate authorities for Authenticated Origin Pulls (AOP) directly from the dashboard.
BYO Client mTLS certificate management — Upload and manage your own CA certificates for client mTLS enforcement without needing API access.
CDN hostname to client mTLS certificate mapping — Associate client mTLS certificates with specific hostnames directly from the dashboard.

Support - Redesigned Support Portal for faster, personalized help

Tue, 07 Apr 2026 00:00:00 GMT

Redesigned "Get Help" Portal for faster, personalized help

Cloudflare has officially launched a redesigned "Get Help" Support Portal to eliminate friction and get you to a resolution faster. Previously, navigating support meant clicking through multiple tiles, categorizing your own technical issues across 50+ conditional fields, and translating your problem into Cloudflare's internal taxonomy.

The new experience replaces that complexity with a personalized front door built around your specific account plan. Whether you are under a DDoS attack or have a simple billing question, the portal now presents a single, clean page that surfaces the direct paths available to you — such as "Ask AI", "Chat with a human", or "Community" — without the manual triage.

What's New

One Page, Clear Choices: No more navigating a grid of overlapping categories. The portal now uses action cards tailored to your plan (Free, Pro, Business, or Enterprise), ensuring you only see the support channels you can actually use.
A Radically Simpler Support Form: We've reduced the ticket submission process from four+ screens and 50+ fields to a single screen with five critical inputs. You describe the issue in your own words, and our backend handles the categorization.
AI-Driven Triage: Using Cloudflare Workers AI ↗ and Vectorize ↗, the portal now automatically generates case subjects and predicts product categories.

Moving complexity to the backend

Behind the scenes, we've moved the complexity from the user to our own developer stack. When you describe an issue, we use semantic embeddings to capture intent rather than just keywords.

By leveraging case-based reasoning, our system compares your request against millions of resolved cases to route your inquiry to the specialist best equipped to help. This ensures that while the front-end experience is simpler for you, the back-end routing is more accurate than ever.

To learn more, refer to the Support documentation or select Get Help directly in the Cloudflare Dashboard ↗.

WAF - WAF Release - 2026-04-07

Tue, 07 Apr 2026 00:00:00 GMT

This week's release introduces new detections for a critical Remote Code Execution (RCE) vulnerability in MCP Server (CVE-2026-23744), alongside targeted protection for an authentication bypass vulnerability in SolarWinds products (CVE-2025-40552). Additionally, this release includes a new generic detection rule designed to identify and block Cross-Site Scripting (XSS) injection attempts leveraging "OnEvent" handlers within HTTP cookies.

Key Findings

MCP Server (CVE-2026-23744): A vulnerability in the Model Context Protocol (MCP) server implementation where malformed input payloads can trigger a memory corruption state, allowing for arbitrary code execution.
SolarWinds (CVE-2025-40552): A critical flaw in the authentication module allows unauthenticated attackers to bypass security filters and gain unauthorized access to the management console due to improper identity token validation.
XSS OnEvents Cookies: This generic rule identifies malicious event handlers (such as onload or onerror) embedded within HTTP cookie values.

Impact

Successful exploitation of the MCP Server and SolarWinds vulnerabilities could allow unauthenticated attackers to execute arbitrary code or gain administrative control, leading to a full system takeover. Additionally, the new generic XSS detection prevents attackers from leveraging browser event handlers in cookies to hijack user sessions or execute malicious scripts.

Ruleset	Legacy Rule ID	Description	Previous Action	New Action	Comments
Cloudflare Managed Ruleset	N/A	Generic Rules - Command Execution - 5 - Body	Log	Disabled	This is a new detection.
Cloudflare Managed Ruleset	N/A	Generic Rules - Command Execution - 5 - Header	Log	Disabled	This is a new detection.

Workers - WebSockets now automatically reply to Close frames

Tue, 07 Apr 2026 00:00:00 GMT

The Workers runtime now automatically sends a reciprocal Close frame when it receives a Close frame from the peer. The readyState transitions to CLOSED before the close event fires. This matches the WebSocket specification ↗ and standard browser behavior.

This change is enabled by default for Workers using compatibility dates on or after 2026-04-07 (via the web_socket_auto_reply_to_close compatibility flag). Existing code that manually calls close() inside the close event handler will continue to work — the call is silently ignored when the WebSocket is already closed.

const [client, server] = Object.values(new WebSocketPair());
server.accept();

server.addEventListener("close", (event) => {
	// readyState is already CLOSED — no need to call server.close().
	console.log(server.readyState); // WebSocket.CLOSED
	console.log(event.code); // 1000
	console.log(event.wasClean); // true
});

Half-open mode for WebSocket proxying

The automatic close behavior can interfere with WebSocket proxying, where a Worker sits between a client and a backend and needs to coordinate the close on both sides independently. To support this use case, pass { allowHalfOpen: true } to accept():

const [client, server] = Object.values(new WebSocketPair());

server.accept({ allowHalfOpen: true });

server.addEventListener("close", (event) => {
	// readyState is still CLOSING here, giving you time
	// to coordinate the close on the other side.
	console.log(server.readyState); // WebSocket.CLOSING

	// Manually close when ready.
	server.close(event.code, "done");
});

For more information, refer to WebSockets Close behavior.

Email security - DANE Support for MX Deployments

Mon, 06 Apr 2026 09:00:00 GMT

Cloudflare Email Security now supports DANE (DNS-based Authentication of Named Entities) for MX deployments. This enhancement strengthens email transport security by enabling DNSSEC-backed certificate verification for our regional MX records.

Regional MX hostnames now publish DANE TLSA records backed by DNSSEC, enabling DANE-capable SMTP senders to cryptographically validate certificate identities before establishing TLS connections—moving beyond opportunistic encryption to verified encrypted delivery.
DANE support is automatically available for all customers using regional MX deployments. No additional configuration is required; DANE-capable mail infrastructure will automatically validate MX certificates using the published records.

This applies to all Email Security packages:

Cloudflare Fundamentals, Cloudflare One, Gateway, Organizations - Organizations is now in public beta for enterprises

Mon, 06 Apr 2026 00:00:00 GMT

We're announcing the public beta of Organizations for enterprise customers, a new top-level Cloudflare container that lets Cloudflare customers manage multiple accounts, members, analytics, and shared policies from one centralized location.

What's New

Organizations [BETA]: Organizations are a new top-level container for centrally managing multiple accounts. Each Organization supports up to 500 accounts and 5000 zones, giving larger teams a single place to administer resources at scale.

Self-serve onboarding: Enterprise customers can create an Organization in the dashboard and assign accounts where they are already Super Administrators.

Centralized Account Management: At launch, every Organization member has the Organization Super Admin role. Organization Super Admins can invite other users and manage any child account under the Organization implicitly. Shared policies: Share WAF or Gateway policies across multiple accounts within your Organization to simplify centralized policy management. Implicit access: Members of an Organization automatically receive Super Administrator permissions across child accounts, removing the need for explicit membership on each account. Additional Org-level roles will be available over the course of the year.

Unified analytics: View, filter, and download aggregate HTTP analytics across all Organization child accounts from a single dashboard for centralized visibility into traffic patterns and security events.

Terraform provider support: Manage Organizations with infrastructure as code from day one. Provision organizations, assign accounts, and configure settings programmatically with the Cloudflare Terraform provider ↗.

Shared policies: Share WAF or Gateway policies across multiple accounts within your Organization to simplify centralized policy management.

Logs - New ResponseTimeMs field in Gateway DNS Logpush dataset

Mon, 06 Apr 2026 00:00:00 GMT

Cloudflare has added a new field to the Gateway DNS Logpush dataset:

ResponseTimeMs: Total response time of the DNS request in milliseconds.

For the complete field definitions, refer to Gateway DNS dataset.

Containers - Control where your Containers run with regional and jurisdictional placement

Sun, 05 Apr 2026 00:00:00 GMT

You can now specify placement constraints to control where your Containers run.

Constraint	Values	Use case
`regions`	`ENAM`, `WNAM`, `EEUR`, `WEUR`	Geographic placement
`jurisdiction`	`eu`, `fedramp`	Compliance boundaries

Use regions to limit placement to specific geographic areas. Use jurisdiction to restrict containers to compliance boundaries — eu maps to European regions (EEUR, WEUR) and fedramp maps to North American regions (ENAM, WNAM).

Refer to Containers placement for more details.

Access - Session management for MCP server portals

Thu, 02 Apr 2026 00:00:00 GMT

MCP server portals support in-session management of upstream MCP server connections. Users can return to the server selection page at any time to enable or disable servers, reauthenticate, or change which data a server has access to — all without leaving their MCP client.

To return to the server selection page, ask your AI agent with a prompt like "take me back to the server selection page." The portal responds with an authorization URL via MCP elicitation ↗ that you open in your browser:

https://<subdomain>.<domain>/authorize?elicitationId=<ELICITATION_ID>

From the server selection page you can:

Enable or disable servers — Toggle individual upstream MCP servers on or off. Disabling a server removes its tools from the active session, which reduces context window usage.
Log out and reauthenticate — Log out of a server and log back in to change which data the server has access to, or to reauthenticate with different permissions.

Users can also enable or disable a server inline by asking their AI agent directly, for example "enable the wiki server" or "disable my Jira server."

The portal also automatically prompts connected users to authorize new servers when an admin adds them to the portal. This requires the use of managed OAuth.

For more information, refer to Manage portal sessions.

AI Gateway - Automatically retry on upstream provider failures on AI Gateway

Thu, 02 Apr 2026 00:00:00 GMT

AI Gateway now supports automatic retries at the gateway level. When an upstream provider returns an error, your gateway retries the request based on the retry policy you configure, without requiring any client-side changes.

You can configure the retry count (up to 5 attempts), the delay between retries (from 100ms to 5 seconds), and the backoff strategy (Constant, Linear, or Exponential). These defaults apply to all requests through the gateway, and per-request headers can override them.

This is particularly useful when you do not control the client making the request and cannot implement retry logic on the caller side. For more complex failover scenarios — such as failing across different providers — use Dynamic Routing.

For more information, refer to Manage gateways.

Logs - BigQuery as Logpush destination

Thu, 02 Apr 2026 00:00:00 GMT

Cloudflare Logpush now supports BigQuery as a native destination.

Logs from Cloudflare can be sent to Google Cloud BigQuery ↗ via Logpush. The destination can be configured through the Logpush UI in the Cloudflare dashboard or by using the Logpush API.

For more information, refer to the Destination Configuration documentation.

Workflows, Workers - All Wrangler commands for Workflows now support local development

Wed, 01 Apr 2026 12:00:00 GMT

All wrangler workflows commands now accept a --local flag to target a Workflow running in a local wrangler dev session instead of the production API.

You can now manage the full Workflow lifecycle locally, including triggering Workflows, listing instances, pausing, resuming, restarting, terminating, and sending events:

npx wrangler workflows list --local
npx wrangler workflows trigger my-workflow --local
npx wrangler workflows instances list my-workflow --local
npx wrangler workflows instances pause my-workflow <INSTANCE_ID> --local
npx wrangler workflows instances send-event my-workflow <INSTANCE_ID> --type my-event --local

All commands also accept --port to target a specific wrangler dev session (defaults to 8787).

For more information, refer to Workflows local development.

AI Search - Create, manage, search AI Search instances with Wrangler CLI

Wed, 01 Apr 2026 00:00:00 GMT

AI Search supports a wrangler ai-search command namespace. Use it to manage instances from the command line.

The following commands are available:

Command	Description
`wrangler ai-search create`	Create a new instance with an interactive wizard
`wrangler ai-search list`	List all instances in your account
`wrangler ai-search get`	Get details of a specific instance
`wrangler ai-search update`	Update the configuration of an instance
`wrangler ai-search delete`	Delete an instance
`wrangler ai-search search`	Run a search query against an instance
`wrangler ai-search stats`	Get usage statistics for an instance

The create command guides you through setup, choosing a name, source type (r2 or web), and data source. You can also pass all options as flags for non-interactive use:

wrangler ai-search create my-instance --type r2 --source my-bucket

Use wrangler ai-search search to query an instance directly from the CLI:

wrangler ai-search search my-instance --query "how do I configure caching?"

All commands support --json for structured output that scripts and AI agents can parse directly.

For full usage details, refer to the Wrangler commands documentation.

Cloudflare One, Access, Gateway - Logs UI refresh

Wed, 01 Apr 2026 00:00:00 GMT

Access authentication logs and Gateway activity logs (DNS, Network, and HTTP) now feature a refreshed user interface that gives you more flexibility when viewing and analyzing your logs.

The updated UI includes:

Filter by field - Select any field value to add it as a filter and narrow down your results.
Customizable fields - Choose which fields to display in the log table. Querying for fewer fields improves log loading performance.
View details - Select a timestamp to view the full details of a log entry.
Switch to classic view - Return to the previous log viewer interface if needed.

For more information, refer to Access authentication logs and Gateway activity logs.

Radar - Routing Section Expansion on Cloudflare Radar

Wed, 01 Apr 2026 00:00:00 GMT

Radar now features an expanded Routing section ↗ with dedicated sub-pages, providing a more organized and in-depth view of the global routing ecosystem. This restructuring lays the groundwork for additional routing features and widgets coming in the near future.

Dedicated sub-pages

The single Routing page has been split into three focused sub-pages:

Overview ↗ — Routing statistics, IP address space trends, BGP announcements, and the new Top 100 ASes ranking.
RPKI ↗ — RPKI validation status, ASPA deployment trends, and per-ASN ASPA provider details.
Anomalies ↗ — BGP route leaks, origin hijacks, and Multi-Origin AS (MOAS) conflicts.

New widgets

The routing overview now includes a Top 100 ASes table ranking autonomous systems by customer cone size, IPv4 address space, or IPv6 address space. Users can switch between rankings using a segmented control.

The RPKI sub-page introduces a RPKI validation view for per-ASN pages, showing prefixes grouped by RPKI validation status (Valid, Invalid, Unknown) with visibility scores.

Improved IP address space chart

The IP address space ↗ chart now displays both IPv4 and IPv6 trends stacked vertically and is available on global, country, and AS views.

Check out the Radar routing section ↗ to explore the data, and stay tuned for more routing insights coming soon.

Rules - New QUIC RTT and delivery rate fields

Wed, 01 Apr 2026 00:00:00 GMT

Two new fields are now available in rule expressions that surface Layer 4 transport telemetry from the client connection. Together with the existing cf.timings.client_tcp_rtt_msec field, these fields give you a complete picture of connection quality for both TCP and QUIC traffic — enabling transport-aware rules without requiring any client-side changes.

Previously, QUIC RTT and delivery rate data was only available via the Server-Timing: cfL4 response header. These new fields make the same data available directly in rule expressions, so you can use them in Transform Rules, WAF Custom Rules, and other phases that support dynamic fields.

New fields

Field	Type	Description
`cf.timings.client_quic_rtt_msec`	Integer	The smoothed QUIC round-trip time (RTT) between Cloudflare and the client in milliseconds. Only populated for QUIC (HTTP/3) connections. Returns `0` for TCP connections.
`cf.edge.l4.delivery_rate`	Integer	The most recent data delivery rate estimate for the client connection, in bytes per second. Returns `0` when L4 statistics are not available for the request.

Example: Route slow connections to a lightweight origin

Use a request header transform rule to tag requests from high-latency connections, so your origin can serve a lighter page variant:

Rule expression:

cf.timings.client_tcp_rtt_msec > 200 or cf.timings.client_quic_rtt_msec > 200

Header modifications:

Operation	Header name	Value
Set	`X-High-Latency`	`true`

Example: Match low-bandwidth connections

cf.edge.l4.delivery_rate > 0 and cf.edge.l4.delivery_rate < 100000

For more information, refer to Request Header Transform Rules and the fields reference.

Workers - Deploy Hooks are now available for Workers Builds

Wed, 01 Apr 2026 00:00:00 GMT

Workers Builds now supports Deploy Hooks — trigger builds from your headless CMS, a Cron Trigger, a Slack bot, or any system that can send an HTTP request.

Each Deploy Hook is a unique URL tied to a specific branch. Send it a POST and your Worker builds and deploys.

curl -X POST "https://api.cloudflare.com/client/v4/workers/builds/deploy_hooks/<DEPLOY_HOOK_ID>"

To create one, go to Workers & Pages > your Worker > Settings > Builds > Deploy Hooks.

Since a Deploy Hook is a URL, you can also call it from another Worker. For example, a Worker with a Cron Trigger can rebuild your project on a schedule:

export default {
	async scheduled(event, env, ctx) {
		ctx.waitUntil(fetch(env.DEPLOY_HOOK_URL, { method: "POST" }));
	},
};

export default {
  async scheduled(event: ScheduledEvent, env: Env, ctx: ExecutionContext): Promise<void> {
    ctx.waitUntil(fetch(env.DEPLOY_HOOK_URL, { method: "POST" }));
  },
} satisfies ExportedHandler<Env>;

You can also use Deploy Hooks to rebuild when your CMS publishes new content or deploy from a Slack slash command.

Built-in optimizations

Automatic deduplication: If a Deploy Hook fires multiple times before the first build starts running, redundant builds are automatically skipped. This keeps your build queue clean when webhooks retry or CMS events arrive in bursts.
Last triggered: The dashboard shows when each hook was last triggered.
Build source: Your Worker's build history shows which Deploy Hook started each build by name.

Deploy Hooks are rate limited to 10 builds per minute per Worker and 100 builds per minute per account. For all limits, see Limits & pricing.

To get started, read the Deploy Hooks documentation.

Workers - New L4 transport telemetry fields in Workers

Wed, 01 Apr 2026 00:00:00 GMT

Three new properties are now available on request.cf in Workers that expose Layer 4 transport telemetry from the client connection. These properties let your Worker make decisions based on real-time connection quality signals — such as round-trip time and data delivery rate — without requiring any client-side changes.

Previously, this telemetry was only available via the Server-Timing: cfL4 response header. These new properties surface the same data directly in the Workers runtime, so you can use it for routing, logging, or response customization.

New properties

Property	Type	Description
`clientTcpRtt`	number \| undefined	The smoothed TCP round-trip time (RTT) between Cloudflare and the client in milliseconds. Only present for TCP connections (HTTP/1, HTTP/2). For example, `22`.
`clientQuicRtt`	number \| undefined	The smoothed QUIC round-trip time (RTT) between Cloudflare and the client in milliseconds. Only present for QUIC connections (HTTP/3). For example, `42`.
`edgeL4`	Object \| undefined	Layer 4 transport statistics. Contains `deliveryRate` (number) — the most recent data delivery rate estimate for the connection, in bytes per second. For example, `123456`.

Example: Log connection quality metrics

export default {
  async fetch(request) {
    const cf = request.cf;

    const rtt = cf.clientTcpRtt ?? cf.clientQuicRtt ?? 0;
    const deliveryRate = cf.edgeL4?.deliveryRate ?? 0;
    const transport = cf.clientTcpRtt ? "TCP" : "QUIC";

    console.log(`Transport: ${transport}, RTT: ${rtt}ms, Delivery rate: ${deliveryRate} B/s`);

    const headers = new Headers(request.headers);
    headers.set("X-Client-RTT", String(rtt));
    headers.set("X-Delivery-Rate", String(deliveryRate));

    return fetch(new Request(request, { headers }));
  },
};

For more information, refer to Workers Runtime APIs: Request.

WAF - WAF Release - 2026-03-30

Mon, 30 Mar 2026 00:00:00 GMT

This week's release introduces new detections for a critical authentication bypass vulnerability in Fortinet products (CVE-2025-59718), alongside three new generic detection rules designed to identify and block HTTP Parameter Pollution attempts. Additionally, this release includes targeted protection for a high-impact unrestricted file upload vulnerability in Magento and Adobe Commerce.

Key Findings

CVE-2025-59718: An improper cryptographic signature verification vulnerability in Fortinet FortiOS, FortiProxy, and FortiSwitchManager. This may allow an unauthenticated attacker to bypass the FortiCloud SSO login authentication using a maliciously crafted SAML message, if that feature is enabled on the device.
Magento 2 - Unrestricted File Upload: A critical flaw in Magento and Adobe Commerce allows unauthenticated attackers to bypass security checks and upload malicious files to the server, potentially leading to Remote Code Execution (RCE).

Impact

Successful exploitation of the Fortinet and Magento vulnerabilities could allow unauthenticated attackers to gain administrative control or deploy webshells, leading to complete server compromise and data theft.

Ruleset	Legacy Rule ID	Description	Previous Action	New Action	Comments
Cloudflare Managed Ruleset	N/A	Generic Rules - Parameter Pollution - Body	Log	Disabled	This is a new detection.
Cloudflare Managed Ruleset	N/A	Generic Rules - Parameter Pollution - Header - Form	Log	Disabled	This is a new detection.
Cloudflare Managed Ruleset	N/A	Generic Rules - Parameter Pollution - URI	Log	Disabled	This is a new detection.
Cloudflare Managed Ruleset	N/A	Magento 2 - Unrestricted file upload	Log	Block	This is a new detection.
Cloudflare Managed Ruleset	N/A	Fortinet FortiCloud SSO - Authentication Bypass - CVE:CVE-2025-59718	Log	Block	This is a new detection.

Workers - New RFC 9440 mTLS certificate fields in Workers

Fri, 27 Mar 2026 00:00:00 GMT

Four new fields are now available on request.cf.tlsClientAuth in Workers for requests that include a mutual TLS (mTLS) client certificate. These fields encode the client certificate and its intermediate chain in RFC 9440 ↗ format — the same standard format used by the Client-Cert and Client-Cert-Chain HTTP headers — so your Worker can forward them directly to your origin without any custom parsing or encoding logic.

New fields

Field	Type	Description
`certRFC9440`	String	The client leaf certificate in RFC 9440 format (`:base64-DER:`). Empty if no client certificate was presented.
`certRFC9440TooLarge`	Boolean	`true` if the leaf certificate exceeded 10 KB and was omitted from `certRFC9440`.
`certChainRFC9440`	String	The intermediate certificate chain in RFC 9440 format as a comma-separated list. Empty if no intermediates were sent or if the chain exceeded 16 KB.
`certChainRFC9440TooLarge`	Boolean	`true` if the intermediate chain exceeded 16 KB and was omitted from `certChainRFC9440`.

Example: forwarding client certificate headers to your origin

export default {
  async fetch(request) {
    const tls = request.cf.tlsClientAuth;

    // Only forward if cert was verified and chain is complete
    if (!tls || !tls.certVerified || tls.certRevoked || tls.certChainRFC9440TooLarge) {
      return new Response("Unauthorized", { status: 401 });
    }

    const headers = new Headers(request.headers);
    headers.set("Client-Cert", tls.certRFC9440);
    headers.set("Client-Cert-Chain", tls.certChainRFC9440);

    return fetch(new Request(request, { headers }));
  },
};

For more information, refer to Client certificate variables and Mutual TLS authentication.

Access - Code Mode for MCP server portals

Thu, 26 Mar 2026 00:00:00 GMT

MCP server portals support Code Mode MCP server patterns, a technique that reduces context window usage by replacing individual tool definitions with a single code execution tool. Code Mode is turned on by default on all portals.

To turn it off, edit the portal in Access controls > AI controls and turn off Code Mode under Basic information.

When Code Mode is active, the portal exposes a single code tool instead of listing every tool from every upstream MCP server. The connected AI agent writes JavaScript that calls typed codemode.* methods for each upstream tool. The generated code runs in an isolated Dynamic Worker environment, keeping authentication credentials and environment variables out of the model context.

To use Code Mode, append ?codemode=search_and_execute to your portal URL when connecting from an MCP client:

https://<subdomain>.<domain>/mcp?codemode=search_and_execute

For more information, refer to Code Mode.

Access - Context optimization for MCP server portals

Thu, 26 Mar 2026 00:00:00 GMT

MCP server portals support two context optimization options that reduce how many tokens tool definitions consume in the model's context window. Both options are activated by appending the optimize_context query parameter to the portal URL.

`minimize_tools`

Strips tool descriptions and input schemas from all upstream tools, leaving only their names. The portal exposes a special query tool that agents use to retrieve full definitions on demand. This provides up to 5x savings in token usage.

https://<subdomain>.<domain>/mcp?optimize_context=minimize_tools

`search_and_execute`

Hides all upstream tools and exposes only two tools: query and execute. The query tool searches and retrieves tool definitions. The execute tool runs the upstream tools in an isolated Dynamic Worker environment. This reduces the initial token cost to a small constant, regardless of how many tools are available through the portal.

https://<subdomain>.<domain>/mcp?optimize_context=search_and_execute

For more information, refer to Optimize context.

Containers - Easily connect Containers and Sandboxes to Workers

Thu, 26 Mar 2026 00:00:00 GMT

Containers and Sandboxes now support connecting directly to Workers over HTTP. This allows you to call Workers functions and bindings, like KV or R2, from within the container at specific hostnames.

Run Worker code

Define an outbound handler to capture any HTTP request or use outboundByHost to capture requests to individual hostnames and IPs.

export class MyApp extends Sandbox {}

MyApp.outbound = async (request, env, ctx) => {
	// you can run arbitrary functions defined in your Worker on any HTTP request
	return await someWorkersFunction(request.body);
};

MyApp.outboundByHost = {
	"my.worker": async (request, env, ctx) => {
		return await anotherFunction(request.body);
	},
};

In this example, requests from the container to http://my.worker will run the function defined within outboundByHost, and any other HTTP requests will run the outbound handler. These handlers run entirely inside the Workers runtime, outside of the container sandbox.

Access Workers bindings

Each handler has access to env, so it can call any binding set in Wrangler config. Code inside the container makes a standard HTTP request to that hostname and the outbound Worker translates it into a binding call.

export class MyApp extends Sandbox {}

MyApp.outboundByHost = {
	"my.kv": async (request, env, ctx) => {
		const key = new URL(request.url).pathname.slice(1);
		const value = await env.KV.get(key);
		return new Response(value ?? "", { status: value ? 200 : 404 });
	},
	"my.r2": async (request, env, ctx) => {
		const key = new URL(request.url).pathname.slice(1);
		const object = await env.BUCKET.get(key);
		return new Response(object?.body ?? "", { status: object ? 200 : 404 });
	},
};

Now, from inside the container sandbox, curl http://my.kv/some-key will access Workers KV and curl http://my.r2/some-object will access R2.

Access Durable Object state

Use ctx.containerId to reference the container's automatically provisioned Durable Object.

export class MyContainer extends Container {}

MyContainer.outboundByHost = {
	"get-state.do": async (request, env, ctx) => {
		const id = env.MY_CONTAINER.idFromString(ctx.containerId);
		const stub = env.MY_CONTAINER.get(id);
		return stub.getStateForKey(request.body);
	},
};

This provides an easy way to associate state with any container instance, and includes a built-in SQLite database.

Get Started Today

Upgrade to @cloudflare/containers version 0.2.0 or later, or @cloudflare/sandbox version 0.8.0 or later to use outbound Workers.

Refer to Containers outbound traffic and Sandboxes outbound traffic for more details and examples.

Data Loss Prevention - Streaming ZIP file scanning removes per-file size limits

Thu, 26 Mar 2026 00:00:00 GMT

DLP now processes ZIP files using a streaming handler that scans archive contents element-by-element as data arrives. This removes previous file size limitations and improves memory efficiency when scanning large archives.

Microsoft Office documents (DOCX, XLSX, PPTX) also benefit from this improvement, as they use ZIP as a container format.

This improvement is automatic — no configuration changes are required.

Durable Objects, Workers - Access Durable Object jurisdiction via `ctx.id.jurisdiction`

Thu, 26 Mar 2026 00:00:00 GMT

ctx.id.jurisdiction inside a Durable Object now reports the jurisdiction the object was created in — for example "eu" when accessed through env.MY_DURABLE_OBJECT.jurisdiction("eu") — so you can make region-aware decisions without passing the jurisdiction through method arguments or persisting it in storage. For the full list of ID-construction paths that preserve jurisdiction, refer to the Durable Object ID documentation.

export class RegionalRoom extends DurableObject {
	async fetch(request) {
		// "eu" when accessed through env.MY_DURABLE_OBJECT.jurisdiction("eu")
		const region = this.ctx.id.jurisdiction;
		return new Response(`Hello from ${region ?? "the default region"}!`);
	}
}

// Worker
export default {
	async fetch(request, env) {
		const stub = env.MY_DURABLE_OBJECT.jurisdiction("eu").getByName("general");
		return stub.fetch(request);
	},
};

ctx.id.jurisdiction is undefined for Durable Objects that were not created in a jurisdiction-restricted namespace. Alarms scheduled before 2026-03-15 also do not have jurisdiction stored; to backfill the value, reschedule the alarm from a fetch() or RPC handler.

Radar - URL Scanner improvements on Cloudflare Radar

Thu, 26 Mar 2026 00:00:00 GMT

Radar ships several improvements to the URL Scanner ↗ that make scan reports more informative and easier to share:

Live screenshots — the summary card now includes an option to capture a live screenshot of the scanned URL on demand using the Browser Rendering API.
Save as PDF — a new button generates a print-optimized document aggregating all tab contents (Summary, Security, Network, Behavior, and Indicators) into a single file.
Download as JSON — raw scan data is available as a JSON download for programmatic use.
Redesigned summary layout — page information and security details are now displayed side by side with the screenshot, with a layout that adapts to narrower viewports.
File downloads — downloads are separated into a dedicated card with expandable rows showing each file's source URL and SHA256 hash.
Detailed IP address data — the Network tab now includes additional detail per IP address observed during the scan.

Explore these improvements on the Cloudflare Radar URL Scanner ↗.

Data Loss Prevention - Detect and sanitize HAR files

Wed, 25 Mar 2026 00:00:00 GMT

HTTP Archive (HAR) files are used by engineering and support teams to capture and share web traffic logs for troubleshooting. However, these files routinely contain highly sensitive data — including session cookies, authorization headers, and other credentials — that can pose a significant risk if uploaded to third-party services without being reviewed or cleaned first.

Gateway now includes a predefined DLP profile called Unsanitized HAR that detects HAR files in HTTP traffic. You can use this profile in a Gateway HTTP policy to either block HAR file uploads entirely or redirect users to a sanitization tool before allowing the upload to proceed.

How to configure a HAR file policy

In the Cloudflare dashboard ↗, go to Zero Trust > Traffic policies > Firewall Policies > HTTP and create a new HTTP policy using the DLP Profile selector:

Selector	Operator	Value	Action
DLP Profile	in	Unsanitized HAR

Then choose one of the following actions:

Block: Prevents the upload of any HAR file that has not been sanitized by Cloudflare's sanitizer. Use this for strict environments where HAR file sharing must be disallowed entirely.
Block with Gateway Redirect: Intercepts the upload and redirects the user to https://har-sanitizer.pages.dev/, where they can sanitize the file. Once sanitized, the user can re-upload the clean file and proceed with their workflow.

Sanitized HAR recognition

HAR files processed by the Cloudflare HAR sanitizer receive a tamper-evident sanitized marker. DLP recognizes this marker and will not re-trigger the policy on a file that has already been sanitized and has not been modified since. If a previously sanitized file is edited, it will be treated as unsanitized and flagged again.

Visibility in Gateway logs

Gateway logs will reflect whether a detected HAR file was classified as Unsanitized or Sanitized, giving your security team full visibility into HAR file activity across your organization.

For more information, refer to predefined DLP profiles.

logpush, Logs - Logpush — More granular timestamps

Wed, 25 Mar 2026 00:00:00 GMT

Logpush now supports higher-precision timestamp formats for log output. You can configure jobs to output timestamps at millisecond or nanosecond precision. This is available in both the Logpush UI in the Cloudflare dashboard and the Logpush API.

To use the new formats, set timestamp_format in your Logpush job's output_options:

rfc3339ms — 2024-02-17T23:52:01.123Z
rfc3339ns — 2024-02-17T23:52:01.123456789Z

Default timestamp formats apply unless explicitly set. The dashboard defaults to rfc3339 and the API defaults to unixnano.

For more information, refer to the Log output options documentation.

Rules - New mTLS certificate fields for Transform Rules

Wed, 25 Mar 2026 00:00:00 GMT

Cloudflare now exposes four new fields in the Transform Rules phase that encode client certificate data in RFC 9440 ↗ format. Previously, forwarding client certificate information to your origin required custom parsing of PEM-encoded fields or non-standard HTTP header formats. These new fields produce output in the standardized Client-Cert and Client-Cert-Chain header format defined by RFC 9440, so your origin can consume them directly without any additional decoding logic.

Each certificate is DER-encoded, Base64-encoded, and wrapped in colons. For example, :MIIDsT...Vw==:. A chain of intermediates is expressed as a comma-separated list of such values.

New fields

Field	Type	Description
`cf.tls_client_auth.cert_rfc9440`	String	The client leaf certificate in RFC 9440 format. Empty if no client certificate was presented.
`cf.tls_client_auth.cert_rfc9440_too_large`	Boolean	`true` if the leaf certificate exceeded 10 KB and was omitted. In practice this will almost always be `false`.
`cf.tls_client_auth.cert_chain_rfc9440`	String	The intermediate certificate chain in RFC 9440 format as a comma-separated list. Empty if no intermediate certificates were sent or if the chain exceeded 16 KB.
`cf.tls_client_auth.cert_chain_rfc9440_too_large`	Boolean	`true` if the intermediate chain exceeded 16 KB and was omitted.

The chain encoding follows the same ordering as the TLS handshake: the certificate closest to the leaf appears first, working up toward the trust anchor. The root certificate is not included.

Example: Forwarding client certificate headers to your origin server

Add a request header transform rule to set the Client-Cert and Client-Cert-Chain headers on requests forwarded to your origin server. For example, to forward headers for verified, non-revoked certificates:

Rule expression:

cf.tls_client_auth.cert_verified and not cf.tls_client_auth.cert_revoked

Header modifications:

Operation	Header name	Value
Set	`Client-Cert`	`cf.tls_client_auth.cert_rfc9440`
Set	`Client-Cert-Chain`	`cf.tls_client_auth.cert_chain_rfc9440`

To get the most out of these fields, upload your client CA certificate to Cloudflare so that Cloudflare validates the client certificate at the edge and populates cf.tls_client_auth.cert_verified and cf.tls_client_auth.cert_revoked.

For more information, refer to Mutual TLS authentication, Request Header Transform Rules, and the fields reference.

Workers - Declare required secrets in your Wrangler configuration

Wed, 25 Mar 2026 00:00:00 GMT

The new secrets configuration property lets you declare the secret names your Worker requires in your Wrangler configuration file. Required secrets are validated during local development and deploy, and used as the source of truth for type generation.

{
	"secrets": {
		"required": ["API_KEY", "DB_PASSWORD"],
	},
}

[secrets]
required = [ "API_KEY", "DB_PASSWORD" ]

Local development

When secrets is defined, wrangler dev and vite dev load only the keys listed in secrets.required from .dev.vars or .env/process.env. Additional keys in those files are excluded. If any required secrets are missing, a warning is logged listing the missing names.

Type generation

wrangler types generates typed bindings from secrets.required instead of inferring names from .dev.vars or .env. This lets you run type generation in CI or other environments where those files are not present. Per-environment secrets are supported — the aggregated Env type marks secrets that only appear in some environments as optional.

Deploy

wrangler deploy and wrangler versions upload validate that all secrets in secrets.required are configured on the Worker before the operation succeeds. If any required secrets are missing, the command fails with an error listing which secrets need to be set.

For more information, refer to the secrets configuration property reference.

AI Crawl Control - Advanced WAF customization for AI Crawl Control blocks

Tue, 24 Mar 2026 00:00:00 GMT

AI Crawl Control now supports extending the underlying WAF rule with custom modifications. Any changes you make directly in the WAF custom rules editor — such as adding path-based exceptions, extra user agents, or additional expression clauses — are preserved when you update crawler actions in AI Crawl Control.

If the WAF rule expression has been modified in a way AI Crawl Control cannot parse, a warning banner appears on the Crawlers page with a link to view the rule directly in WAF.

For more information, refer to WAF rule management.

Cache - Cache Response Rules

Tue, 24 Mar 2026 00:00:00 GMT

You can now control how Cloudflare handles origin responses without changing your origin. Cache Response Rules let you modify Cache-Control directives, manage cache tags, and strip headers like Set-Cookie from origin responses before they reach Cloudflare's cache. Whether traffic is cached or passed through dynamically, these rules give you control over origin response behavior that was previously out of reach.

What changed

Cache Rules previously only operated on request attributes. Cache Response Rules introduce a new response phase that evaluates origin responses and lets you act on them before caching. You can now:

Modify Cache-Control directives: Set or remove individual directives like no-store, no-cache, max-age, s-maxage, stale-while-revalidate, immutable, and more. For example, remove a no-cache directive your origin sends so Cloudflare can cache the asset, or set an s-maxage to control how long Cloudflare stores it.
Set a different browser Cache-Control: Send a different Cache-Control header downstream to browsers and other clients than what Cloudflare uses internally, giving you independent control over edge and browser caching strategies.
Manage cache tags: Add, set, or remove cache tags on responses, including converting tags from another CDN's header format into Cloudflare's Cache-Tag header. This is especially useful if you are migrating from a CDN that uses a different tag header or delimiter.
Strip headers that block caching: Remove Set-Cookie, ETag, or Last-Modified headers from origin responses before caching, so responses that would otherwise be treated as uncacheable can be stored and served from cache.

Benefits

No origin changes required: Fix caching behavior entirely from Cloudflare, even when your origin configuration is locked down or managed by a different team.
Simpler CDN migration: Match caching behavior from other CDN providers without rewriting your origin. Translate cache tag formats and override directives that do not align with Cloudflare's defaults.
Native support, fewer workarounds: Functionality that previously required workarounds is now built into Cache Rules with full Tiered Cache compatibility.
Fine-grained control: Use expressions to match on request and response attributes, then apply precise cache settings per rule. Rules are stackable and composable with existing Cache Rules.

Get started

Configure Cache Response Rules in the Cloudflare dashboard ↗ under Caching > Cache Rules, or via the Rulesets API ↗. For more details, refer to the Cache Rules documentation ↗.

Containers - Use Docker Hub images with Containers

Tue, 24 Mar 2026 00:00:00 GMT

Containers now support Docker Hub ↗ images. You can use a fully qualified Docker Hub image reference in your Wrangler configuration ↗ instead of first pushing the image to Cloudflare Registry.

{
	"containers": [
		{
			// Example: docker.io/cloudflare/sandbox:0.7.18
			"image": "docker.io/<NAMESPACE>/<REPOSITORY>:<TAG>",
		},
	],
}

[[containers]]
image = "docker.io/<NAMESPACE>/<REPOSITORY>:<TAG>"

Containers also support private Docker Hub images. To configure credentials, refer to Use private Docker Hub images.

For more information, refer to Image management.

Gateway - OIDC Claims filtering now available in Gateway Firewall, Resolver, and Egress policies

Tue, 24 Mar 2026 00:00:00 GMT

Cloudflare Gateway now supports OIDC Claims as a selector in Firewall, Resolver, and Egress policies. Administrators can use custom OIDC claims from their identity provider to build fine-grained, identity-based traffic policies across all Gateway policy types.

With this update, you can:

Filter traffic in DNS, HTTP, and Network firewall policies based on OIDC claim values.
Apply custom resolver policies to route DNS queries to specific resolvers depending on a user's OIDC claims.
Control egress policies to assign dedicated egress IPs based on OIDC claim attributes.

For example, you can create a policy that routes traffic differently for users with department=engineering in their OIDC claims, or restrict access to certain destinations based on a user's role claim.

To get started, configure custom OIDC claims on your identity provider and use the OIDC Claims selector in the Gateway policy builder.

For more information, refer to Identity-based policies.

Network Interconnect - Interconnects moved to Connectors

Tue, 24 Mar 2026 00:00:00 GMT

The top-level Interconnects page in the Cloudflare dashboard has been removed. Interconnects are now located under Connectors > Interconnects.

Your existing configurations and functionality remain the same.

Workers - Dynamic Workers, now in open beta

Tue, 24 Mar 2026 00:00:00 GMT

Dynamic Workers are now in open beta ↗ for all paid Workers users. You can now have a Worker spin up other Workers, called Dynamic Workers, at runtime to execute code on-demand in a secure, sandboxed environment. Dynamic Workers start in milliseconds, making them well suited for fast, secure code execution at scale.

Use Dynamic Workers for

Code Mode: LLMs are trained to write code. Run tool-calling logic written in code instead of stepping through many tool calls, which can save up to 80% in inference tokens and cost.
AI agents executing code: Run code for tasks like data analysis, file transformation, API calls, and chained actions.
Running AI-generated code: Run generated code for prototypes, projects, and automations in a secure, isolated sandboxed environment.
Fast development and previews: Load prototypes, previews, and playgrounds in milliseconds.
Custom automations: Create custom tools on the fly that execute a task, call an integration, or automate a workflow.

Executing Dynamic Workers

Dynamic Workers support two loading modes:

load(code) — for one-time code execution (equivalent to calling get() with a null ID).
get(id, callback) — caches a Dynamic Worker by ID so it can stay warm across requests. Use this when the same code will receive subsequent requests.

export default {
	async fetch(request, env) {
		const worker = env.LOADER.load({
			compatibilityDate: "2026-01-01",
			mainModule: "src/index.js",
			modules: {
				"src/index.js": `
					export default {
						fetch() {
							return new Response("Hello from a dynamic Worker");
						},
					};
				`,
			},
			// Block all outbound network access from the Dynamic Worker.
			globalOutbound: null,
		});

		return worker.getEntrypoint().fetch(request);
	},
};

export default {
	async fetch(request: Request, env: Env): Promise<Response> {
		const worker = env.LOADER.load({
			compatibilityDate: "2026-01-01",
			mainModule: "src/index.js",
			modules: {
				"src/index.js": `
					export default {
						fetch() {
							return new Response("Hello from a dynamic Worker");
						},
					};
				`,
			},
			// Block all outbound network access from the Dynamic Worker.
			globalOutbound: null,
		});

		return worker.getEntrypoint().fetch(request);
	},
};

Helper libraries for Dynamic Workers

Here are 3 new libraries to help you build with Dynamic Workers:

@cloudflare/codemode ↗: Replace individual tool calls with a single code() tool, so LLMs write and execute TypeScript that orchestrates multiple API calls in one pass.
@cloudflare/worker-bundler ↗: Resolve npm dependencies and bundle source files into ready-to-load modules for Dynamic Workers, all at runtime.
@cloudflare/shell ↗: Give your agent a virtual filesystem inside a Dynamic Worker with persistent storage backed by SQLite and R2.

Try it out

Dynamic Workers Starter

Use this starter ↗ to deploy a Worker that can load and execute Dynamic Workers.

Dynamic Workers Playground

Deploy the Dynamic Workers Playground ↗ to write or import code, bundle it at runtime with @cloudflare/worker-bundler, execute it through a Dynamic Worker, and see real-time responses and execution logs.

For the full API reference and configuration options, refer to the Dynamic Workers documentation.

Pricing

Dynamic Workers pricing is based on three dimensions: Dynamic Workers created daily, requests, and CPU time.

	Included	Additional usage
Dynamic Workers created daily	1,000 unique Dynamic Workers per month	+$0.002 per Dynamic Worker per day
Requests ¹	10 million per month	+$0.30 per million requests
CPU time ¹	30 million CPU milliseconds per month	+$0.02 per million CPU milliseconds

¹ Uses Workers Standard rates and will appear as part of your existing Workers bill, not as separate Dynamic Workers charges.

Note: Dynamic Workers requests and CPU time are already billed as part of your Workers plan and will count toward your Workers requests and CPU usage. The Dynamic Workers created daily charge is not yet active — you will not be billed for the number of Dynamic Workers created at this time. Pricing information is shared in advance so you can estimate future costs.
