Use tool ↗About Theneo
Theneo turns an API spec into a published reference, then keeps the surrounding developer portal (guides, changelogs, authenticated customer portals) in the same place. Editing works like a document, with live cursors and comments, and its AI drafts descriptions and answers reader questions through an embedded assistant. It also emits llms.txt and an MCP server so agents can read the docs. Theneo, Inc. was founded in 2021 by Ana Robakidze and Maria Doliashvili, went through Y Combinator's W22 batch, and builds from Tbilisi. The free tier covers one public project; Business runs $120 a month on annual billing.

Pros & cons of Theneo
The pitch is Stripe-grade API docs without hiring a docs team, and the collaborative editor plus generated changelogs is what makes it stick after launch. The agent-facing extras (llms.txt, an MCP server, private per-customer portals) are ahead of most doc tools. Price is the gate: the free tier is a single public project, and the first real plan is $120 a month per workspace.
Pros
- Generates reference documentation directly from an API spec
- Real-time co-editing with live cursors and comments
- Private, authenticated customer portals with per-customer visibility controls
- Ships llms.txt and an MCP server so AI agents can consume the docs
- Self-hosting available on the enterprise tier
Cons
- Jump from free to $120/month per workspace is steep for small teams
- Project caps per tier: 7 on Business, 20 portals on Growth
- Hosted SaaS by default, with self-hosting reserved for enterprise
Best for
- teams publishing a public API reference without a docs writer
- products needing private per-customer documentation
- engineering orgs that want changelogs generated from spec changes
Not for
- side projects that fit inside the single free public project
- teams committed to docs-as-code inside their own repo
Watch out: Prices are per workspace rather than per seat, so a second product line means a second workspace bill.
