OpenAPI DevTools is a powerful Firefox extension that automatically generates OpenAPI 3.1 specifications in real time by capturing network requests from any app or website. Once installed, it adds a dedicated OpenAPI tab to the Firefox DevTools, where you can monitor live network traffic being converted into a comprehensive API specification.

Key features include automatic merging of request and response headers, bodies, and query parameters per endpoint, as well as intelligent handling of path parameters by merging matching requests. Users can easily view, download, export, and share API specifications or sessions directly from the tool. This extension streamlines API documentation and testing without manual effort, making it an essential tool for developers and API designers.
