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 is open source (AGPL-3.0) and Outline is not (Business Source License 1.1 (source-available, not OSI open source)) — so the real question is whether you want to own the wikis & internal docs stack or rent it.
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.

Which one fits you
The trade-offs above, turned into a decision. Find the line that describes your team.
Choose Docmost
if you want the source and the option to fork it, and best editing experience of the open options — genuinely modern.
Choose Outline
if best design and editing experience of anything on this page.
Neither, yet
if both carry a real cost you should weigh first — youngest project here; shortest production history, and nOT open source — Business Source License, despite near-universal mislabelling. If either of those is a dealbreaker for your team, the shortlist is wrong rather than the choice.
What it takes to run these yourself
Real requirements and honest running costs, not the vendor quickstart.
Docmost vs Outline — common questions
Is Docmost a better fit than Outline for wikis & internal docs?
It depends on what you are optimising for, and the honest split is this: Docmost scores 90 to Outline's 66 on data ownership and exit cost, so it is the safer choice if you care about being able to leave. Outline earns its place on a different axis — best design and editing experience of anything on this page. Neither is a wrong answer for every team; the table above is the actual comparison.
What happens if we want to switch later?
Docmost keeps its data local or in open formats, so leaving is an export rather than a negotiation. Outline is still self-hostable, so the files stay on your server either way — but it is not local-first by design, so check what its export produces before you rely on it.
Can I self-host Docmost or Outline?
Both can be self-hosted. The difference is what it costs you in time rather than whether it is possible — see the setup and maintenance rows above.
Are Docmost and Outline both alternatives to Confluence?
Yes — both appear in our Confluence comparison, which is why they are worth putting side by side. People usually arrive here already having decided to move off Confluence and now choosing between the two replacements, which is a narrower and much easier question.
