harview lets you browse HAR files directly in your terminal—no browser required. It's designed for developers and security professionals who prefer the command line and want a quick, lightweight way to inspect HTTP traffic in the terminal.

• Split-Pane Interface — Request list on top, detailed view below
• Search & Filter — Vim-style / search with full regex support; filter by URL, host, headers, body, status code, method, size, duration, and more. Matches are highlighted in both the table and the detail pane
• Tab Navigation — Quickly switch between Headers, Cookies, Request, Response, and Help tabs
• Syntax Highlighting — Toggle with h. Supports JSON, HTML, XML, JavaScript, and CSS. Automatically skipped for bodies over 200KB to keep the UI responsive — use b to open large content in bat instead
• Pretty Printing — Auto-formatted JSON and XML/HTML for readability
• Base64 Decoding — Response bodies with base64 encoding are automatically decoded for display

The top pane displays a list of all entries with the following columns:

• Pane-Aware Scrolling — Scroll independently in list or details pane based on cursor position
• Visual Focus Indicator — Active pane highlighted with a green border
• Clickable Tabs — Switch views with a single click
• Clickable Rows — Click a row in the request table to select it

External viewers are available on the Request and Response tabs. They open the current tab's body in an external program for full-featured viewing.

• fx — Open JSON bodies for advanced querying and exploration (only activates for JSON content)
• bat — Open bodies with syntax highlighting. File type is auto-detected from the response MIME type (json, html, js, css, xml)
• $EDITOR — Open bodies in your preferred editor (falls back to vi)

git clone https://github.com/armsultan/harview.git
cd harview
cargo install --path . --locked

If needed, add $HOME/.cargo/bin to your PATH to be able to run the installed binaries

#zsh
echo 'export PATH="$HOME/.cargo/bin:$PATH"' >> ~/.zshrc && source ~/.zshrc
# bash
echo 'export PATH="$HOME/.cargo/bin:$PATH"' >> ~/.bashrc && source ~/.bashrc

# To verify it worked:
which harview

• Rust (cargo)
• fx (optional, for JSON viewing): npm install -g fx or via package manager
• bat (optional, for enhanced text viewing): brew install bat or equivalent

Open your browser's DevTools (F12), go to the Network tab, and export the session as a HAR file.

harview path/to/file.har

The search bar appears at the bottom of the request table while active:

/ [ALL] api\.example▏                              47/312

Search scopes (cycle with Tab):

Regex examples: ^GET, 4\d{2}, application/json, api/v[0-9]+
