API Capture Pro

API Capture Pro instantly captures every Fetch/XHR API call your browser makes — no manual setup, no proxy, no server required. WHY USE IT If you're a developer, QA engineer, or API integrator, you've probably opened DevTools' Network tab a hundred times just to find one request, copy its headers, and manually rebuild it in Postman. API Capture Pro automates that entire workflow. HOW IT WORKS 1. Add the site(s) you want to track (or capture everywhere — your choice) 2. Browse your app normally — every Fetch/XHR call is captured automatically in the background 3. Open the popup to search, filter, and inspect any request — full headers, body, status, and timing 4. Export straight to a Postman collection, a cURL list, or CSV KEY FEATURES - Automatic capture — no need to manually copy requests one by one - Smart deduplication — collapses repeated calls by method + URL, so you get a clean list of unique endpoints instead of hundreds of duplicate log lines - Scoped capture — track only the sites you choose ("Selected only" mode) or capture everywhere - Auth detection — automatically flags Authorization, Cookie, and tenant/workspace headers plus JWTs so you can spot them at a glance - One-click Postman export — organized into folders by URL path, ready to drag-and-drop import - cURL and CSV export — for scripting, documentation, or sharing with teammates - Noise filtering — static assets, source maps, and analytics calls are filtered out automatically PRIVACY BY DESIGN API Capture Pro runs 100% locally in your browser. There is no backend server — your captured data never leaves your device unless you choose to export it. No accounts, no tracking, no analytics. WHO IT'S FOR - Frontend/backend developers reverse-engineering an API to build against it - QA engineers documenting real API traffic for test cases - Anyone migrating from manual DevTools copy-pasting to a faster Postman-ready workflow Free to use. Load it, browse your app, and export your first Postman collection in minutes.
