HTTP Intelligence Capture

HTTP/API inspection extension

HTTP Intelligence Capture is a powerful, privacy-first alternative to heavy proxy tools like Charles or Fiddler, running entirely inside your browser. It automatically records every API call your web app makes and perfectly correlates them with exactly what UI interactions (clicks, form inputs) triggered them. Key Features: Unified Timeline: See network requests side-by-side with user UI clicks. Deep Capture: Intercepts raw request and response JSON bodies. Smart Filtering: Easily include or exclude specific domains or URL patterns using wildcards. Standalone Popout: Undock the panel into a separate window for a full DevTools-like experience. cURL Generation: One-click export of any request into a replayable cURL command. HAR Export: Download your entire session as a standard HAR file to share with teammates. How to use: Pin the extension and open the side panel on any website. Ensure you have the permissions granted for the active tab (or globally). Interact with the website — network calls and clicks will automatically populate in real-time. Click any request to view its raw request headers, response headers, and JSON bodies. Privacy & Security: Your data is 100% yours. The extension operates entirely locally. All captured network traffic, session recordings, and filter configurations are saved in your browser's sandboxed IndexedDB. No data is ever transmitted to a remote server.
