Outline is what fast-moving teams reach for when Confluence feels slow and Notion feels like it wasn't built for documentation. It's a purpose-built team wiki with real-time collaborative editing, slash commands and search that actually finds things.
Because it's self-hostable, engineering and security teams can run Outline on their own infrastructure and keep company knowledge inside their own network — with the same BSL-licensed source available to audit. It integrates cleanly with Slack, GitHub and SSO providers most teams already use.
Outline organizes docs into nested collections rather than an open-ended page tree, which keeps large wikis navigable as they grow. For teams that want Notion-grade editing with the operational control of self-hosting, Outline is one of the most mature options available.
Multiple people can edit the same document at once, with presence and cursors like Notion or Google Docs.
Docs organize into structured collections instead of an open-ended page tree, keeping big wikis navigable.
Full-text search across every document returns results instantly, even in large knowledge bases.

Outline is free to self-host under the Business Source License. There's also a paid hosted plan if you'd rather not manage the infrastructure yourself.
