Docmost is an open-source team wiki that competes with Notion and Confluence. The software is free under the AGPL license, you host it yourself, and your documents stay on your own server. It competes on collaboration and data ownership rather than on raw feature count. This review is for teams deciding whether it is right for daily use: what works, what does not, and who should pick something else.

The pros

• Real-time collaboration. Several people can edit the same page at once with instant sync, which is the headline feature of tools like Notion and Confluence. It holds up in practice, and it makes live sessions such as incident reviews or planning meetings genuinely faster.
• Your data stays yours. Pages sit in your own PostgreSQL database on your own server. No third party holds them, mines them, or can lock you out. If you leave, you take a database export with you.
• No per-seat pricing. The AGPL license means the software costs nothing no matter how many people you add. Your only real cost is the server it runs on, which makes it cheap at fifty users in a way SaaS wikis are not.
• A familiar interface. Anyone who has used Notion or Confluence is productive in Docmost within minutes. The learning curve is about finding where things live, not about learning a new editor.
• Spaces and permissions. You split content by team or project and control who can view or edit each space. For most small and mid-sized companies that is exactly enough structure without the admin overhead of enterprise wiki tools.
• Light footprint. Docmost runs as one application with PostgreSQL in Docker. A small VM with a few gigabytes of RAM serves a whole team comfortably, so it fits on infrastructure you already have.

The cons

• No native mobile apps. The web interface works in a mobile browser, but there is no offline editing and writing on a phone is fiddly. Teams that live on phones will feel this limitation every day.
• A small ecosystem. There is no plugin marketplace and far fewer integrations than the SaaS incumbents. You get documentation, comments, and search, not databases, calendars, or thousands of connectors.
• Self-hosting is your job. Backups, updates, and uptime are on you unless someone runs it for you. A hosted Docmost server on OpenSysLab removes most of that work, which is the middle ground many teams want.
• No databases or tasks. Docmost does documents only. If you want docs, roadmaps, and task tracking in one tool, you will be running a second product beside it, and that changes the value calculation.
• A younger project. It has fewer years behind it than the incumbents, and some polish and edge cases still lag. Development is active, but if you need every feature finalized today, check the issue tracker first.

Who should use Docmost?

Teams of five to a few hundred people who want a clean, self-hosted wiki benefit most: agencies handling client data, IT and operations teams, and companies avoiding per-seat fees. If one person can handle an occasional Docker update, or your hosting covers that, Docmost fits well.

Who should look elsewhere?

Look elsewhere if your team depends on native mobile apps or offline editing, if you rely on Notion-style databases and automations, or if you want a zero-maintenance SaaS with no server involved at all. Long-time Confluence shops should also weigh migration cost honestly before switching.

The bottom line

Docmost is a strong, honest open-source wiki: real collaboration, real ownership, modest requirements. Its limits are real too: no mobile apps, no databases, a small ecosystem. If none of those block you, start with hosted Docmost and see how the team takes to it before you commit.
