Docmost

TAS Score: S3/3 — D4/5 — A3 / T2 D4 not D5: young project (launched 2024) — trajectory needs more time to evaluate; sustainability depends on continued maintainer commitment (Q8).

Brief Description

Open-source, self-hosted documentation and wiki platform. Real-time collaborative editor with simultaneous editing. Hierarchical page structure with workspaces. AGPL-3.0 licensed. Often described as the selfhosted Notion/Confluence alternative. One of the most popular new selfhosted projects of 2025.

Architectural Role

Knowledge management layer: team documentation, wikis, knowledge bases. Real-time collaboration. Modern alternative to Confluence and Notion.

Technical Autonomy

Works without internet — fully functional on local network
Stores data locally — PostgreSQL database, all content on your server
Does not require external accounts
Allows data export — pages exportable as Markdown and HTML
Provides offline updates — Docker image, updated manually

Philosophical Assessment (whose.world criteria)

Criterion	Status	Comments
Pause	✅	Stop the container. Data persists in PostgreSQL. Resume without loss.
Exit	✅	Export as Markdown. PostgreSQL database directly accessible. Standard formats.
Recoverability	✅	PostgreSQL backup + file storage. Docker-based deployment. Straightforward restore.
Visibility	✅	Fully open source (AGPL-3.0). Source available on GitHub.
External Dependencies	✅	Requires PostgreSQL and Redis — both open source. No external service calls.

Alternatives

Alternative	Autonomy	Notes
BookStack	A3 / T2	More mature (10 years), MIT, no real-time collab, simpler
Confluence	A0 / T0	Enterprise standard, proprietary lock-in, expensive
Notion	A0 / T0	Polished UI, cloud-only

Trajectory

Direction: opening (early stage)

Active development with strong community momentum. AGPL license protects openness. No enterprise split so far. Young project — sustainability depends on continued maintainer commitment and potential business model development. Worth watching.
