Cairn Wiki
An internal wiki is your team's shared brain — versioned docs, structured spaces, fast search. Cairn Wiki is a knowledge base you own, with documents your team keeps current and data that never leaves your cloud.

A complete app, yours to keep.
Every Cairn Trail ships as a complete, AI-native application — full source in your own repository, a native MCP server, and a first-class CLI. Here’s what Cairn Wiki includes out of the box.
- Rich documents organized into spaces
- Version history on every page
- Full-text search across your knowledge
- Permissions by space and team
- Markdown-friendly editing and export
- Native MCP server and CLI so agents can read and write docs
Every way to get knowledge base.
We’d rather you saw the whole map than a sales pitch. Here are the tools teams actually evaluate — what each is good at, said plainly. Cairn is one option among them.

Hosted, polished, rented — your data lives on their cloud.Open source
Self-hostable and yours to run — read each license closely.So why Cairn?
Confluence and Notion have the editors everyone loves — and your company's entire memory lives in their cloud, on their terms. The open-source wikis give you the data back; some trade polish or licensing for it (Outline's BSL, for instance). Cairn Wiki gives you a clean, modern knowledge base as code in your repo — yours to host, search with your own agents, and keep even if you stop paying.
However you get there, Cairn Wiki is software you own — full source in your GitHub repository, running in your own cloud. No phone-home, no license server, no kill switch. Export your data any time; Cairn could disappear tomorrow and your software would keep working.
