Notion
14 alternatives — 8 easy, 6 medium
Notion is powerful but keeps all your data on their servers with limited offline access. These self-hosted alternatives give you full ownership of your notes, wikis, and project management — from lightweight markdown editors to full Notion clones.
Why people leave Notion
- All data stored on US cloud servers
- Pricing increased significantly in recent years
- Vendor lock-in with proprietary block format
- Offline support is limited and unreliable
- API has rate limits and restrictions
- Free tier heavily restricted
- Export options lose formatting and links

FAQ
What is the best open-source Notion alternative?
It depends on your needs. AppFlowy and AFFiNE are the closest to Notion's feature set. Outline is excellent for team wikis. Logseq and Obsidian are better for personal knowledge management with bidirectional linking.
Can I import my Notion data into a self-hosted alternative?
Most alternatives support importing from Notion's markdown export. AppFlowy and AFFiNE have dedicated Notion importers. However, Notion's proprietary block format means some formatting and database views may not transfer perfectly.
Is there a self-hosted Notion alternative with real-time collaboration?
Yes. Outline and CryptPad both support real-time collaboration. AppFlowy is adding collaboration features. For simpler collaborative editing, HedgeDoc works well for markdown documents.
