Docmost is an open-source wiki and knowledge base that teams run on their own servers. If you have used Notion or Confluence, the interface will feel familiar: pages, nested structure, and editing that several people can do at the same time. Docmost is built for teams that want that experience without per-seat pricing or a SaaS vendor holding their documents. It is released under the AGPL license and runs in Docker with PostgreSQL, so a small server is enough. It is not a project tracker or a chat tool; it is a writing and organizing tool for shared knowledge. Agencies, IT departments, and product teams are the typical users.
What is Docmost?
Docmost is a self-hosted documentation platform written in TypeScript, with a React front end and a NestJS back end, first released in 2024. Pages live in a PostgreSQL database on a server you control, and edits sync in real time, so two people typing in the same page see each other’s changes as they happen. Content is organized into spaces, and each space has its own members and permission levels, which makes it easy to separate engineering docs from HR policies. There is no vendor between you and your data and no per-user fee. The feature set is focused rather than huge, and the sections below cover what is in the box today.
What is Docmost used for?
- Internal team wiki. One place for processes, policies, and how-tos, instead of documents scattered across file shares and chat threads that nobody can find later.
- Engineering runbooks. Deployment steps, incident procedures, and architecture notes that the whole team can improve at the same time.
- Onboarding handbooks. New hires get a dedicated space that collects everything they need for their first weeks in the company.
- Meeting notes and decisions. Record what was decided and why, with page history showing how the thinking changed.
- Product specs and research. Draft specifications collaboratively, comment on details in context, and settle on a final version.
- Standard operating procedures. Operations teams keep checklists and procedures where everyone can find them and trust they are current.
Key features
- Real-time collaborative editing. Multiple people edit one page at once, with changes synced instantly.
- Spaces. Group pages into spaces for teams or projects, each with its own membership.
- Permissions. Space-level roles control who can view or edit content.
- Comments. Discuss a page in context, with the conversation attached to the content itself.
- Page history. Every change is versioned, so you can see who changed what and restore an older version.
- Search and attachments. Full-text search across all pages, and files embedded directly in documents.
Docmost on OpenSysLab
Every OpenSysLab server is a private virtual machine in the region you chose at purchase. The app installs automatically in about ten minutes, and the Vibe-code agent inside Open WebUI can read, configure, and manage it for you — you just connect your own AI API key. Servers start at $6/month. See the Docmost product page for plans and regions.
The bottom line
Docmost is a solid pick if you want a Notion-style wiki under your own control and you accept running one more service. It does not try to be a database or a task manager; it focuses on team documentation and covers the essentials well. The hosted version is the fastest way to test it with real users before you commit the team.
