If you're looking for a ReadMe alternative, ReAPI is worth a look. ReAPI is a collection of tools for designing, testing and documenting APIs, including a visual API designer based on OpenAPI, AI-generated schema and examples, and a no-code test case designer. It also has collaboration and versioning abilities so teams can work on API projects together, and it offers detailed test reports and AI-powered help for debugging.
Another contender is Theneo, which uses AI to generate high-quality API documentation with a minimal amount of work. Theneo supports multiple platforms like OpenAPI, Postman and GraphQL, and can automate updates with integrations with GitHub, GitLab and npm packages. It also offers custom branding and advanced analytics, so it can be used for more than just generating API documentation.
