Docmost vs Outline
Both are alternatives to Confluence. Here's how they stack up — verified facts, no spin.
Also searched as Outline vs Docmost — same comparison, one verdict.
Docmost
The modern one — real-time collaborative editing, Notion-like feel.
Docmost is the newest serious entrant and feels it: block-based editor, real-time collaboration, nested pages, comments and diagrams, with the polish people expect after using Notion. AGPL-3.0, around 21k stars and moving quickly. It is the closest thing here to the editing experience that makes people reluctant to leave Confluence. The caveat is age — it has the shortest production track record on this page, and AGPL is strong copyleft worth reading if you intend to modify it.
Outline
The best-looking option — and not open source, whatever the lists say.
Outline is a fast, beautifully judged team knowledge base with excellent search, a slash-command editor and Slack integration that people actually use. It is also the entry on this page most often mislabelled. Outline ships under the **Business Source License 1.1**, not an OSI licence: you may self-host it for internal use, but you may not offer it as a competing hosted service, and the licence converts to open source only after a delay. For most companies documenting their own work that changes nothing. If you were planning to build a product on it, it changes everything — and you would not learn that from the directory that told you it was open source.
