Theneo

What is Theneo?

Theneo is an API documentation platform that turns a specification into a live, interactive reference and keeps it current as the API changes. You import OpenAPI, Swagger, Postman, GraphQL, gRPC, SOAP or AsyncAPI files, and its AI drafts endpoint and parameter descriptions, examples and guides. Engineers, product managers and technical writers then edit in a visual editor with real-time collaboration, comments, version history and rollback. Published docs include an API explorer where readers make authenticated calls, code samples, an automated changelog that flags changes, Ask AI search for readers, and an MCP server and llms.txt so AI agents can read the content. Git sync with GitHub or GitLab, Bitbucket and Postman sync, and a VS Code extension fit it into developer workflows. Pricing starts with a free Starter package, Business costs $120 per month per workspace, Growth is $400 per month per workspace, and a custom Enterprise plan adds self-hosting, SAML SSO and OAuth 2.0.

Use cases

Why use Theneo

• Importing a spec produces a full reference quickly, so teams spend less time writing descriptions by hand.
• Non-engineers can edit docs in a visual editor while engineers own the API schema.
• Spec changes pulled from your repository keep docs from drifting out of date.
• Readers can try calls in the explorer and ask questions through Ask AI instead of opening support tickets.
• A free Starter package lets you test the platform before paying.
