The open-source IRC client and framework for the mobile era.

mIRC taught a generation how to script. IRCap by Carlos Esteve Cremades (since 1997) showed what a truly complete IRC experience could look like. AndroidIRCX carries that spirit forward - open source, built on React Native, and designed so you can learn, hack, extend, and build your own IRC experience from real production code.

Back in the day, mIRC wasn't just an IRC client - it was a platform. Scripts like IRCap turned it into a complete environment with protection systems, away management, writing styles, and channel moderation panels. People learned scripting, built addons, automated bots, and made IRC their own.

AndroidIRCX is built for that same crowd, but open source and for today's platforms.

This is a full-featured, production IRC client - but it's also a learning platform and a * framework* you can study, fork, and build on top of:

• Learn TCP sockets -- see how raw IRC protocol works over react-native-tcp-socket, TLS handshakes, proxy tunneling, SOCKS5/Tor
• Learn state management - Zustand stores and a large set of custom hooks for complex React Native apps
• Learn cryptography - E2E encryption with libsodium (XChaCha20-Poly1305), SCRAM-SHA-256 authentication (RFC 7677), X.509 certificate generation
• Learn protocol implementation - 390+ IRC numeric handlers, full IRCv3 compliance, CAP negotiation, SASL state machines
• Learn architecture - service-oriented design, EventEmitter patterns, context interfaces, modular handler extraction
• Learn testing - extensive Jest coverage across services, hooks, components, stores, utilities, screens, and end-to-end flows
• Learn CI/CD - GitHub Actions, Docker-based release builds, automated coverage reports

Everything is TypeScript. Everything is documented. Everything is yours to read, modify, and ship.

This isn't a toy project. It's a real app on Google Play with real users - and the entire codebase is GPL-3.0, because the best way to learn is from code that actually works in production.

AndroidIRCX follows a service-oriented architecture with clear separation of concerns:

App.tsx -- main UI orchestrator
|
+-- Zustand Stores
|   connectionStore, tabStore, uiStore, messageStore, callStore
|
+-- Custom Hooks
|   Connection lifecycle, tab management, message sending,
|   encryption, DCC, settings, deep links, ads, UI state, and more
|
+-- Components
|   AppLayout, MessageArea, MessageInput, ChannelTabs,
|   UserList, HeaderBar, settings sections, media and certificate modals
|
+-- Screens
|   Settings, network config, theme editor, scripting,
|   key management, privacy, backup, purchases, channel list, help screens
|
+-- Services
|   IRCService -- core protocol handler
|   irc/ -- extracted protocol modules for commands, numerics,
|     send commands, SCRAM-SHA-256 auth, CTCP, batch/label,
|     multiline, and CAP negotiation
|   ConnectionManager, SettingsService, TabService,
|   EncryptedDMService, MediaEncryptionService,
|   ScriptingService, WebRTCCallService, and more
|
+-- Utils
    IRCFormatter, MessageParser, encodings, tab utils

• Context Interfaces -- extracted handler modules receive typed context objects, not full service references. This keeps modules testable and decoupled.
• EventEmitter Communication -- services talk via events, never cross-service direct mutation
• Lazy Initialization -- handlers instantiated on first use
• Write Batching -- messages batched (10/2s), tabs debounced (500ms)
• StorageCache -- LRU cache with TTL over AsyncStorage
• Progressive Loading -- critical data first, message history deferred per-tab

Start with src/services/IRCService.ts -- the connect() method shows raw TCP socket creation, TLS upgrade, proxy tunneling (SOCKS5/HTTP/Tor), and buffer processing. Then look at processBuffer() to see how IRC protocol lines are parsed from a TCP byte stream.

Look at the hooks in src/hooks/ -- they extract complex business logic from components. useConnectionLifecycle.ts shows how to wire up event listeners for a real-time protocol. useLazyMessageHistory.ts shows on-demand data loading patterns.

The src/services/irc/ directory is a textbook implementation of the IRC protocol:

• numerics/ -- 15 modules handling 390+ server response codes
• commands/ -- 18 handlers for every incoming IRC command
• sendCommands/ -- 10 modules for user-initiated commands
• cap/CAPHandlers.ts -- IRCv3 capability negotiation state machine
• ScramAuth.ts -- SCRAM-SHA-256 challenge-response auth (RFC 7677/5802)

• src/services/EncryptedDMService.ts -- TOFU key exchange, key pinning, XChaCha20-Poly1305
• src/services/MediaEncryptionService.ts -- file encryption with context-bound AAD
• src/services/irc/ScramAuth.ts -- SCRAM-SHA-256 with HMAC, PBKDF2, salted hashing
• src/services/CertificateManagerService.ts -- X.509 certificate generation with node-forge

1. Create a handler in src/services/irc/sendCommands/
2. Register it in IRCSendMessageHandlers.ts
3. Add an alias in CommandService.ts
4. Write tests in __tests__/

That's it. The context interface pattern means your handler receives only what it needs -- no god objects, no tight coupling.

• Tap the network name in the header to connect
• Tap the dropdown -> "Connect to Default" for one-click connection
• Connect Another Network for simultaneous multi-network connections

1. Dropdown -> "Choose Network" -> tap [+] in the header
2. Configure: Network Name, Nickname, Alt Nick, Real Name, Auto-Join Channels
3. Add servers with hostname, port, SSL/TLS settings
4. Optional: SASL (PLAIN/SCRAM-SHA-256/EXTERNAL), proxy, client certificate
5. Save

AndroidIRCX supports passwordless authentication with X.509 client certificates:

1. Generate -- Settings -> Network -> SASL EXTERNAL -> Generate New (RSA-2048, SHA-256)
2. Register -- /msg NickServ CERT ADD <fingerprint> or use /certadd
3. Connect -- SASL EXTERNAL authenticates automatically

Commands: /certfp (view fingerprint), /certadd [service] (register with NickServ/CertFP/HostServ)

For networks that support it, SCRAM-SHA-256 provides challenge-response authentication without sending your password in cleartext. Configure SASL with mechanism "SCRAM-SHA-256" in network settings.

GitHub Actions runs the Jest suite with coverage, uploaded to Codecov.

Automated Docker-based builds on push to master:

Dockerfile -> reactnativecommunity/react-native-android
           -> yarn install
           -> prepare-secrets.sh (inject signing keys)
           -> assembleRelease + bundleRelease (armeabi-v7a, arm64-v8a)
           -> upload artifacts

IRCap (c) Carlos Esteve Cremades, 1997-2026 - the legendary mIRC script that inspired AndroidIRCX's away system, protection features, writing styles, and the IRcap theme. If you used mIRC in the 2000s, you probably know IRCap. Its futuristic design and complete feature set set the bar for what an IRC experience should be.

IRcap theme for AndroidIRCX by ARGENTIN07, based on the original IRCap theme.

Translations: ARGENTIN07 and Cubanita83 (Spanish), Yusbastian Lemon (Indonesian). See the full credits in the app's Credits screen.

As an open-source creator, I deeply respect the work of Linus Torvalds and Richard Stallman for the free/open-source software movement. Their vision and persistence were a direct inspiration for building this app as open source.

This project was built with modern tools, including AI-assisted development.

Like robotics in manufacturing, autopilot systems in agriculture, and autocomplete in software, AI is a tool -- no more, no less.

AI did not build this project on its own. Every decision, architectural choice, security consideration, and final line of code was reviewed, validated, and maintained by a human engineer with more than 25 years of professional experience.

AI did not replace engineering judgment; it accelerated routine work so more time could be spent on architecture, quality, and usability.

If you prefer software created without automation or AI assistance, that choice is fully respected. At the same time, refusing tools has never stopped progress -- it has only determined who participates in shaping it.

This project exists to contribute something real to open source, with practical value and long-term maintenance. You are welcome to:

• use it or study it
• fork it or improve it
• or simply ignore it

All are valid choices.

Builders shape the future in silence. Spectators explain it when the work is already done.

In the end, technology moves forward with or without permission. The only question is who chose to be part of it.

Some build loudly. Others build correctly.

Those who recognize the work will understand. Time will explain the rest.
