Limitations and Considerations

• Feature parity with established commercial products is still evolving; some advanced Notion features may be missing or in-progress
• Web deployment and self-hosted web setup can require configuration (CORS, environment variables) and has had community-reported friction during installation
• Commercial/cloud features and enterprise-grade services are shipped separately (cloud offerings and paid tiers); community and plugin ecosystems are active but still maturing

AppFlowy is best suited for users who want control over their data, cross-device native experiences, and an open-source, extensible workspace. It is actively developed with a thriving community, and feature coverage continues to expand through releases and community contributions.
