Docmost provides teams with a self-hosted documentation platform that combines the collaborative editing experience of commercial tools like Notion and Confluence with full data ownership. The real-time editor supports simultaneous editing by multiple users with presence indicators and conflict-free resolution, while the spaces system organizes content into permission-controlled areas for different teams, projects, or access levels. Nested page hierarchies, inline comments, and page history with diff comparison round out the core capabilities.
The diagram integration distinguishes Docmost from simpler wiki alternatives by embedding Draw.io for flowcharts and architecture diagrams, Excalidraw for hand-drawn visuals, and Mermaid for code-defined diagrams directly within the editor. Full-text search spans all workspaces with filtering by space and content type. The attachment system handles images and files with configurable storage backends including local filesystem and S3-compatible object storage for flexible asset management.
The project runs on Node.js with PostgreSQL and deploys through Docker with a single docker-compose configuration. With 19,700+ GitHub stars, 52 releases, and v0.71 released in March 2026, Docmost demonstrates sustained community investment. The AGPL-3.0 license covers the core with an enterprise edition for larger organizations. The self-hosted model appeals to teams in regulated industries or organizations with strict data residency requirements who need Confluence-level features without vendor lock-in.
