Api Reverse Engineer

API Reverse Engineer captures every API call (fetch + XHR) while you browse normally. No DevTools needed — just one click to start recording.

Perfect for:
• Reverse engineering undocumented private APIs
• Building integrations and automation
• Security research and auditing
• API documentation generation
• Learning how web apps communicate

How It Works:
1. Open the extension on any tab
2. (Optional) Set a URL filter to reduce noise
3. Click Start Recording
4. Use the website normally
5. Click Stop → Download JSON

You get a complete JSON export with every unique endpoint: methods, headers, request/response bodies, status codes, and timing.

Key Features:
✓ Intercepts fetch + XHR requests
✓ Tab-scoped recording — only captures from active tab
✓ Live counter badge
✓ Optional URL filter by domain, path, or keyword
✓ Deduplication — one entry per unique endpoint
✓ Works on any website
✓ Clean dark UI
✓ Manifest V3

Privacy: All captures stay on your device. No server uploads, no analytics, no tracking.
