Docmost is an open source collaborative wiki and documentation tool you can self-host — a Confluence and Notion alternative with real-time editing, spaces, permissions, and search that keeps your team's knowledge on your own servers.

What is Docmost?

Docmost is an open source collaborative wiki and documentation tool that teams self-host to write, organize, and share knowledge. You create pages in a rich editor with real-time collaboration, group them into spaces with their own permissions, and find anything through full-text search — all running on your own infrastructure.

What is Docmost best for?

Teams that want a clean, fast company wiki without paying per seat for Confluence or routing internal docs through Notion’s cloud. It suits software teams, ops, and organizations with compliance or air-gapped requirements who need real-time docs but want to keep every page on their own servers.

What can Docmost do?

Edit pages together in real time with comments and full page history
Organize content into spaces, each with its own members and permissions
Draw diagrams inline with Draw.io, Excalidraw, and Mermaid support
Search across everything with full-text search and embed Airtable, Loom, and Miro
Control access with groups and granular, page-level permissions
Connect identity providers via SSO (SAML 2.0, OIDC, LDAP) on paid tiers
Self-host with Docker, including in air-gapped environments, and localize in 10+ languages

Where does Docmost fall short?

It follows an open-core model: the AGPL-3.0 core is fully open, but SSO, granular permissions, AI answers, and audit logs live in a proprietary /ee folder behind paid plans.
The community is smaller and more developer-focused than Confluence or Notion, with support handled largely through GitHub, so expect fewer third-party integrations and templates.

Is Docmost free?

Yes — the Community Edition is free and open source under the AGPL-3.0 license, with unlimited pages, spaces, real-time collaboration, and search, and no per-seat fees. Paid self-managed plans start at $3.50/seat/month billed annually (10-seat minimum) and add SSO, granular permissions, AI, and Confluence migration tools.

What does Docmost replace?

Docmost is a self-hosted alternative to Confluence and Notion. It covers the core team-wiki job — collaborative pages, spaces, permissions, and search — without Atlassian’s per-user pricing or storing your internal documentation in someone else’s cloud.

FAQ

Is Docmost open source? Yes. The core is licensed under AGPL-3.0 and is genuinely open source. Some enterprise features (SSO, audit logs, SCIM) are source-restricted in an /ee folder and gated behind paid plans.

Can I self-host Docmost for free? Yes. The Community Edition is free to self-host with no seat limits; you only pay for the server it runs on. Paid plans are optional and unlock enterprise features like SSO and AI.

Is Docmost a good Confluence alternative? For teams that want a fast, focused wiki they fully control, yes — it covers spaces, permissions, and collaborative editing without per-seat cloud pricing. Confluence still has a larger app marketplace and more enterprise integrations.

What do I need to run Docmost? A server with Docker, a PostgreSQL database, and Redis. It’s built on TypeScript/Node.js and can run fully offline in air-gapped networks.
