Choose Notion if you want one tool for wiki, databases, and project management — it does everything Outline does plus a massive integration ecosystem. Choose Outlineif you need self-hosting, want a faster and more focused wiki, or care deeply about data ownership and privacy.

Frequently Asked Questions
Editor's Take
Here's my honest split: about 80% of teams should use Notion. It does more, integrates with everything, and the free tier is generous. But that other 20% — privacy-first companies, open-source shops, teams with data residency laws — Outline is a genuine lifesaver. I've seen a regulated fintech team switch from Notion to self-hosted Outline and sleep better at night.
