Open-source alternative
Replace GitBook with Docmost / BookStack / Tela
The best open-source alternative to GitBook is Docmost (or BookStack) with zcag/tela, self-hosted on Railway. A team wiki you host, including a Go wiki with MCP so agents can edit the docs — and a GitBook-shaped manual if the job is docs, not notes.
Estimated save $1,920 a year.

FAQ
- Is it free?
- The Docmost / BookStack / Tela licenses are open source or fair-code. You still pay hosting (Railway or any VPS) and any APIs the stack calls. There is no GitBook seat or task bill on this path.
- Can I migrate from GitBook?
- Yes. Start with the workflows or data you actually use, then cut over. The Docmost / BookStack / Tela stack page has the agent prompt and the cost table; most teams rebuild the slice that matters and leave old GitBook links until they expire.
- How do I deploy it?
- Open the Docmost / BookStack / Tela stack, copy the agent prompt, and deploy on Railway (one service, PORT, and a volume when the app needs disk). Placeholder: Docmost for a polished wiki, Tela if you want MCP baked in.
- What does this replace?
- Notion / Confluence / GitBook. The published small-team estimate on this stack is $1,920 a year.
