ReadMe helps companies document their APIs. Teams upload an OpenAPI specification, and the platform generates an interactive reference with code samples in several languages and a try-it console that makes real requests with the reader’s own key. Guides and changelogs sit alongside, forming a single developer hub.
It is also a source of insight. API owners see which endpoints developers use, where requests fail, and which pages cause confusion, so documentation can improve based on evidence. Personalized docs show a logged-in developer their own API keys and data, which makes onboarding faster. An AI assistant answers questions from the documentation.
ReadMe has a free tier and paid plans for custom domains, branding, and analytics. It focuses on API documentation, and general knowledge bases may be better served by other tools. Alternatives include Mintlify, Stoplight, Redocly, GitBook, and Docusaurus for open source. ReadMe suits companies with public or partner APIs.
