API Forensics

Professional API & network traffic inspector. Capture requests, detect schema shifts, replay calls, and export to Postman.

API Forensics is a professional-grade network traffic analyzer designed specifically for front-end developers, QA engineers, and security auditors. Stop switching back and forth between DevTools and your editor—keep your API data right alongside your application in a dedicated, high-performance Side Panel. Key Forensic Features: Deep Inspection: Capture every XHR and Fetch request with full header, body, and response visibility. Schema Drift Detection: Automatically track the "shape" of your JSON responses. Be the first to know when a backend change breaks your data contracts. Sandbox Replay: Need to test a request again? Replay any captured call with one click or modify it in our built-in sandbox. Postman Export: Instantly turn your debugging session into a Postman Collection for documentation or team sharing. Persistent History: Track the performance and reliability of your endpoints over time with locally stored history.
