What the free edition leaves out

The free edition is genuinely usable, but some team or enterprise features need a paid plan. “Not confirmed” means the official pages we read did not say, so we do not guess.

Open-core feature checklist for Docmost
Feature	Free edition	Details	Source
SSO / SAML	Paid	SAML 2.0, OIDC and LDAP are marked Enterprise in the authentication docs. The pricing page appears to list SSO under Business as well, so the exact edition needs a recheck. Either way it is not in the free edition.	Source ↗
Role-based access control	Free	Spaces and groups with permissions are in the free edition. Page-level granular permissions are listed under Business.	Source ↗
Audit logs	Paid	Audit logs and SIEM integration are described as Enterprise features.	Source ↗
Multi-user / teams	Free	The free Open Source edition is described as including core collaboration features. No user limit was found.	Source ↗
Backups and restore	Not confirmed	No built-in backup tool is described on the pages read.	Source ↗
API access	Paid	The API docs say the API is an enterprise feature and needs an active enterprise license. The pricing page appears to list API keys under Business, so the exact edition needs a recheck.	Source ↗
Support SLA	Paid	Community support is listed for the free edition, email for Business, priority for Enterprise. No SLA was found.	Source ↗

Best for

Small to mid-size teams that want a modern, real-time collaborative wiki they can self-host.

Why choose it over Confluence

The core is AGPL-3.0 and free to self-host, with real-time collaboration, spaces, groups, comments, page history, search, file attachments and diagrams (Draw.io, Excalidraw, Mermaid). It is a newer, lighter wiki than Confluence and can be started from one compose file. Upgrading to a paid edition keeps your data.

Where it falls short

SSO (SAML, OIDC, LDAP), the API and audit logs sit behind paid licenses (some at Business, some at Enterprise), which matters for company use. Business has a 10-seat minimum on the pricing page. No official hosted offer was confirmed, and no built-in backup tool was found. Compared with Confluence, the ecosystem and integrations are much smaller (not measured here).

Open-source alternative to

Confluence — Docmost is a self-hosted collaborative wiki with spaces, permissions and page history, so it can replace Confluence for team documentation.
Notion — Docmost offers a collaborative editor with embeds and diagrams on your own server, covering the wiki and docs use of Notion.
