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.
SilverBullet
- No native mobile apps; mobile use relies on the web interface
- Real-time multi-user collaboration is limited compared to cloud-first tools
- Plugin ecosystem is much smaller than Obsidian's community plugin library
- No built-in rich media embedding or database views comparable to Notion
Bottom line
Choose SilverBullet 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.
