Where each falls short
The honest trade-offs — what you give up with each, versus the proprietary tools they replace.
AppFlowy
- Self-hosted AppFlowy Cloud setup is involved and less polished than the local desktop app.
- Fewer database view types and formula capabilities than Notion.
- Limited third-party integrations and public API.
- Real-time multiplayer collaboration is newer and less battle-tested.
Zettlr
- No mobile app; desktop-only experience limits on-the-go access
- No real-time collaboration or multi-user sync; single-user only
- Cloud sync relies entirely on third-party tools (Dropbox, Syncthing, etc.)
Bottom line
Choose Zettlr if you want the lower-effort setup; choose AppFlowy for the larger community and ecosystem. AppFlowy has seen more recent development. Open each guide below for deploy steps and the full feature gap.
