Overview
Docmost is an open-source collaborative documentation and wiki tool positioned as a Confluence and Notion alternative. It features real-time collaborative editing, nested pages/spaces, permissions, comments, and diagramming support. It self-hosts cleanly with Docker Compose using Postgres and Redis.
Key features
- Real-time collaborative editing of pages
- Nested pages organized into spaces
- Per-space and per-page permissions
- Inline comments on documents
- Diagramming support within pages
Our take
Docmost covers the core of what most teams actually use a wiki for: nested pages in spaces, real-time co-editing, comments, permissions, and inline diagrams, without the bloat of heavier suites. The Docker Compose setup is clean, though it does mean standing up and maintaining Postgres and Redis alongside the app, so budget for a little more than a single-container deploy. It's a relatively young project compared to entrenched alternatives, so expect a smaller feature surface and fewer integrations than Confluence or Notion. The AGPL-3.0 license is worth noting if you plan to modify and offer it as a network service. For straightforward team documentation that stays on your own infrastructure, it's a sensible pick.
Ideal for: Small-to-midsize teams that want a self-hosted Confluence or Notion replacement for internal wikis and documentation.
Where it falls short of Confluence
- Younger project with a smaller feature set than Confluence.
- No database/table views or relational content like Notion.
- Some enterprise features (SSO/SAML) are gated to a paid edition.
- Smaller integration and extension ecosystem.
