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.
Paperless-ngx
- Primarily a document archive, not a note-taking or collaboration tool.
- Mobile scanning requires a third-party app (e.g., Scanbot) pointing at the consume folder.
- No real-time collaboration or shared editing of documents.
- Initial OCR processing of large backlogs can be slow and CPU-intensive.
Bottom line
Both are a similar lift to self-host; choose AppFlowy for the larger community and ecosystem. Open each guide below for deploy steps and the full feature gap.
