Theneo vs ReadMe: the alternative for teams who outgrew one project

Yes. Theneo is a direct alternative to ReadMe for teams that have outgrown a single-project setup. ReadMe is a capable documentation platform, and most teams who move to Theneo do so because they hit structural ceilings rather than because the product is poor. The most common triggers are the one-project-per-account limit, the need for multi-project separation by product line, region or audience, forced slug flattening that breaks existing URL structures, and access controls or SSO that sit behind ReadMe's Enterprise tier. Theneo supports unlimited projects, preserves your existing URL paths on migration, and includes collaboration and access controls across plans rather than gating them at the top tier.

The clearest differences are structural rather than feature-by-feature. Theneo supports unlimited projects with cross-project search and navigation, while ReadMe is built around one project per account and places multi-project management on its Enterprise plan. Theneo preserves your existing URL and slug structure on import, so paths like /api/v1/user/account/balance stay intact, where ReadMe flattens slugs and typically forces a redirect project to migrate in. Theneo generates API changelogs automatically from spec changes and offers email subscriptions, where ReadMe's changelog is entered manually with no automatic detection of API changes. Theneo also offers real-time collaborative editing with review and approval workflows, richer formatting inside the API reference itself, and self-hosted deployment via Docker.

ReadMe does offer MCP server generation and llms.txt, and both work for basic discovery and retrieval. The difference is depth and operational control. Theneo's MCP layer is built for teams running agent traffic in production: usage logs and analytics so you can see which tools agents actually call, access-aware responses so the server respects the same permissions as your docs and never surfaces private, hidden or deprecated content, and programmatic access to changelog and spec data. On ReadMe, documentation search and fetch tools for MCP require a paid add-on, and the server exposes the same content to every user regardless of permissions. If you are investing in AEO and agent visibility, the operational and permission layers matter more than whether the endpoint exists.

ReadMe publishes three tiers: Starter at no cost, Pro at $300 per month, and Enterprise starting around $3,000 per month. Starter includes one admin. Pro includes five admins and charges $20 for each additional admin. A significant set of capabilities sits on Enterprise only, including SAML, OAuth 2.0, editor and viewer roles, multi-project management, multi-project search and navigation, global landing pages, audit logs and removal of ReadMe branding. AI search is a paid add-on rather than part of the base plan. Theneo prices on flat tiers with no per-seat or per-admin charges, and includes collaboration, access control and agent readiness across plans instead of reserving them for the highest tier.
