The self-hosted, open-source Nuclino alternative
Last updated June 30, 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.
