Docmost is a collaborative documentation platform designed for teams preparing shared reference material, onboarding guides and project knowledge bases. The interface is organised around spaces, allowing content and permissions to be separated by team or subject.
Contributors work in a rich-text editor with Markdown shortcuts and can edit a shared page together without having to coordinate separate copies. Its combination of page history, discussion and visual content makes it useful when maintaining living documents that multiple people need to improve over time.
Docmost is intended for teams that want to write together rather than pass document files between colleagues. Contributors can work within departmental or project areas, discuss individual pages and use embedded visual material when a written explanation is insufficient. Its model is particularly relevant to onboarding documentation, internal policies and shared technical runbooks.
This is free and open source software.
