About OpenAPI DevTools

Instantly generate API specifications in real time for any app or website. OpenAPI DevTools generates OpenAPI specifications in real time from network requests. Once installed it adds a new tab to Chrome DevTools called OpenAPI. While the tool is open it automatically converts network requests into a specification. The algorithm works locally on your device. This extension doesn't make requests of any form. It only has access to network requests when developer tools is open and you have begun recording. Features: - Instantly generate an OpenAPI 3.1 specification for any website or application just by using it - Automatically merges new request & response headers, bodies, and query parameters per endpoint - Click on a path parameter and the app will automatically merge existing and future matching requests - View the specification inside the tool and download with a click - Export and save a session at any time, or share it with others
