Overview

Product summary

Review the store description, core capabilities, and common use cases.

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

Add arrows to the search so I can cycle through my search. Trying to find stuff in the output window and all it does is highlight it and not even automatically go to it

Didn't work at all for me. Paths is empty and description states "Contains 0 endpoints". Documentation is poor.

Excited to try this out! Definitely a huge need for automated API documentation for time-strapped devs like myself.
