The open-source GitBook alternative that documents itself
Last updated September 9, 2026
GitBook is polished for public product docs, but it is proprietary SaaS you cannot self-host, priced per published site, and its Git Sync only mirrors markdown you already wrote. tela is the switch for internal team knowledge you own — markdown-native, self-hostable, and generated from your actual source.
tela vs GitBook, at a glance
| Feature | tela | GitBook |
|---|---|---|
| License | Open source (AGPL-3.0) | Proprietary SaaS |
| Self-hostable | Yes — self-host free, plus a free cloud tier | No — cloud only |
| Ask your docs (AI) | Built in — ranked full-text always, plus semantic Ask that cites its sources (self-host brings its own model) | AI on its top tier |
| Agents read & write (MCP) | Built in — agents read and write, scoped per token, over a hosted endpoint | MCP, but read-only (published docs) |
| Generate docs from your code | Yes — Atlas builds a cited, coverage-checked wiki from git repos and Jira | No — Git Sync mirrors existing markdown |
| Publishing to the web | Publish a whole space to the open web — no-login reader, clean /handle/space URLs, RSS and a sitemap | Its whole purpose — and better at it: branded, versioned, multi-version docs sites |
| What a page can be | Docs, presentations and spreadsheets are all page types — plus mermaid, drawings and charts | Documentation pages |
Why teams switch to tela
- Atlas writes the first draft from your code; GitBook's Git Sync only mirrors markdown you authored by hand.
- Agents are full citizens — GitBook's MCP is read-only and exposes only published docs; tela's agents search and write your live wiki.
- Self-host under AGPL and keep portable markdown, instead of renting per published site.
- One place for the whole team, not just the docs team: the same space holds runbooks, meeting notes, a budget spreadsheet and a deck, and you can still flip any of it public with a no-login reader, RSS and a sitemap.
When GitBook is the better choice
If your job is beautiful public-facing developer documentation — versioned API references, multi-version docs for an open-source library, a branded docs site — GitBook is excellent and hard to beat. tela is a team wiki, not a public docs-publishing platform.
