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.
SiYuan
- Primarily single-user; no real-time team collaboration.
- Official cloud sync and some features require a paid subscription.
- Documentation and UI are translated from Chinese and can be uneven.
- Smaller English-language community and plugin ecosystem.
