The self-hosted, open-source Nuclino alternative
Last updated September 9, 2026
Nuclino is fast and has a capable AI assistant with citations and an official MCP server, so the contrast with tela is not about AI existing — it is where your knowledge lives and how far the automation goes. Nuclino is proprietary and cloud-only, with the full assistant gated to its top tier. tela is open-source, self-hostable, stores markdown you own, and Atlas generates docs from your code.
tela vs Nuclino, at a glance
| Feature | tela | Nuclino |
|---|---|---|
| License | Open source (AGPL-3.0) | Proprietary SaaS |
| Self-hostable | Yes — self-host free, plus a free cloud tier | No — cloud only |
| Storage | Canonical markdown you own — export is a copy, not a conversion | Its own editor format; markdown is import/export |
| Ask your docs (AI) | Built in — ranked full-text always, plus semantic Ask that cites its sources (self-host brings its own model) | "Sidekick" — full version on the top tier |
| Agents read & write (MCP) | Built in — agents read and write, scoped per token, over a hosted endpoint | Yes — official MCP server |
| Generate docs from your code | Yes — Atlas builds a cited, coverage-checked wiki from git repos and Jira | No |
| Sync to a folder on your disk | Two-way — mount /dav/ as a folder of .md files with any WebDAV client, or bisync it with rclone | Your items live in Nuclino; the way out is an export |
Why teams switch to tela
- Self-host and own your data — Nuclino is cloud-only with no on-prem option, and a tela space also mounts on your own disk as ordinary .md files you can open in any editor.
- AI is not paywalled to the top tier — semantic retrieval and Ask are in the free core, and on self-host they run on your own model.
- Atlas generates a cited wiki from repos and Jira; Nuclino is a manual wiki.

Nuclino is exceptionally fast and simple, with a lovely lightweight UX, instant graph/board/canvas views, and zero setup. For a frictionless hosted team wiki where speed and minimalism matter more than self-hosting and repo-to-doc generation, it is a delightful choice.
