Docmost
Collaborative wiki and documentation platform with spaces, permissions and diagrams — a self-hostable open-source alternative to Confluence.
ConfluenceAbout Docmost
Docmost is a young but fast-moving collaborative wiki built for teams that find Confluence slow or overpriced. It pairs real-time editing with spaces, granular permissions and built-in diagramming, so documentation and diagrams live in the same place.
Because it's self-hostable with Docker and licensed AGPL-3.0, teams can run it entirely on their own infrastructure and keep internal documentation off third-party servers, while still getting a modern editing experience.
Key features
- Spaces & permissions — Organize documentation into spaces with granular, per-space permission controls.
- Real-time editing — Multiple people can edit the same page simultaneously, with live cursors and presence.
- Diagrams built in — Drop in draw.io and Mermaid diagrams directly inside a page — no separate tool needed.
- Self-hostable — Deploy with Docker Compose and keep every document on your own infrastructure.
