Overview
Outline is an open-source wiki and knowledge base. Beautiful editor, real-time collaboration, nested collections. Notion/Confluence alternative for team documentation.
Pros

- Real-time collaboration
- Nested collections and structure
- Full API
- Self-hosted option
- SSO/SAML support

Verdict
Outline is the best self-hosted team wiki. The editor is polished enough that people actually want to write in it — which is the hardest problem in documentation tooling. The nested collections provide structure without rigidity, and real-time collaboration means your team can work together without merge conflicts.
