Project overview
OpenAPI DevTools is a Chrome and Firefox extension that watches network traffic in a dedicated DevTools tab and builds an OpenAPI 3.1 specification as an application is used. It merges requests, responses, headers, bodies, query parameters, and configured path parameters, then lets users preview, export, or share the result. The repository now directs users to the rewritten successor, Demystify, for the expanded and final version.
