Open-source tool to generate OpenAPI docs from your code
We built an open-source tool that scans your codebase and generates OpenAPI docs in minutes. Right now it supports Rails, Go, Python, and NodeJS frameworks, and we will keep adding more. It picks up routes, params, request bodies, and models directly from the code and outputs a clean OpenAPI spec you can drop into your workflow.
In plain words
This open-source tool automatically generates OpenAPI documentation by scanning codebases and extracting routes, parameters, request bodies, and data models directly from the code. It currently supports Rails, Go, Python, and NodeJS frameworks with plans to add more. The tool produces a clean, ready-to-use OpenAPI specification that developers can integrate into their existing workflows, eliminating the need to manually write API documentation.
