Why Teams Choose It Over Notion

Notion is proprietary, can be slow, and charges per member:

Self-hosted — own your team's knowledge, no vendor lock-in
Faster than Notion — optimized React app, instant search
Open source — customize, add features, audit code
No per-seat pricing — unlimited members when self-hosted

A 30-person engineering team was paying $240/mo for Notion Team. They migrated to self-hosted Outline — same collaborative wiki, faster search, and their sensitive product docs never leave their infrastructure.
