Outline
Fast, self-hostable team wiki and knowledge base — a Notion alternative for docs.
Self-hosted Open source BSL 1.1 wikidocsself-hosting
Pricing
Free (self-hosted). Cloud from $10/user/month.
Outline focuses specifically on team documentation — collections, nested docs, real-time collaborative editing — without trying to be an everything-app the way Notion has become.
Key features
- Real-time collaborative markdown editing
- Nested collections mirror how teams actually organize docs
- Full-text search that’s genuinely fast
- SSO support (Google, Slack, OIDC) even self-hosted
Self-hosted vs. cloud
Self-hosted requires Postgres, Redis, and S3-compatible storage — a real but manageable stack. Outline Cloud removes that setup for a per-seat fee.
Quick start
git clone https://github.com/outline/outline.git
docker compose up -d
Alternatives
BookStack is a lighter-weight option if real-time collaborative editing isn’t a requirement.
