As AI applications increasingly rely on inference APIs, keeping API documentation accurate and easy to maintain has become more important.
I’ve been looking at alternatives to Mintlify, especially for teams working with model APIs, OpenAPI specifications, and rapidly changing endpoints.
Here are 10 options worth considering:
Apidog is interesting for AI API workflows because it combines API design, documentation, testing, mocking, and OpenAPI management in one platform.
A lightweight option for teams that mainly need interactive OpenAPI documentation.
Useful when OpenAPI governance, validation, and documentation customization are important.
Still a straightforward choice for generating interactive documentation directly from OpenAPI specifications.
A good option for teams looking for a more structured API design and documentation workflow.
Interesting when API documentation needs to live alongside broader developer documentation in a Git-based workflow.
Useful for teams that want documentation, collaboration, and publishing capabilities beyond API reference pages.
A strong option for teams building public-facing developer portals around their APIs.
Worth considering when automatically generating and updating API documentation from OpenAPI specifications is the priority.
For smaller projects, keeping documentation directly in Git and generating API references from OpenAPI can still be a very practical approach. AI APIs can be a little different from traditional REST APIs. Model versions, inference parameters, dynamic responses, authentication, and rapidly changing endpoints can make documentation harder to maintain.
For simple OpenAPI documentation, tools like Scalar or Swagger UI may be enough.
For larger developer portals, ReadMe or GitBook can make sense.
For teams wanting API design, testing, documentation, and collaboration together, **Apidog** is the option I’ve found most interesting.
I’m curious what other Hugging Face developers are using.
Which Mintlify alternative would you recommend for documenting AI or inference APIs?
