What is it?

Docmost is a collaborative wiki and documentation platform for teams that want to organize knowledge in shared spaces. It provides real-time multi-user editing, page history, comments, and full-text search, so teams can write, review, and find documentation in one place.

The editor supports embedded diagrams from Draw.io, Excalidraw, and Mermaid, along with file attachments and embeds from services such as Airtable, Loom, and Miro. Access is controlled through spaces, permissions, and groups, and the interface is translated into 10+ languages.

The core is licensed under AGPL-3.0, with enterprise features under a separate license in designated directories. A hosted cloud version is also offered for those who do not want to run their own instance.
