FastOpenAPI is an emerging tool designed to automate the generation of OpenAPI documentation for various Python web frameworks, particularly appealing to developers who enjoy the routing style of FastAPI but are working on projects using frameworks such as Flask, Sanic, Falcon, or Starlette. Users have expressed that they find the project promising, highlighting its clean implementation and ease of use (particularly with decorators). There are ongoing discussions regarding the best approaches for API specification, with a divide between spec-first versus code-first philosophies. Additionally, developers are seeking improved UI solutions for documentation that are open-source and visually appealing, pointing out that many current options are proprietary. As the project develops, feedback and community contributions are encouraged. There is also interest in refining tools to help filter large OpenAPI specifications effectively. The conversation reflects a broader trend of integrating streamlined documentation processes across multiple frameworks to enhance developer productivity.
