What is AppFlowy?

AppFlowy is the leading open-source alternative to Notion, built for individuals and teams who want full control over their data. Written in Flutter and Rust for native performance, AppFlowy provides documents, databases (grid, board, calendar), tasks, wikis, and AI-assisted writing — all in a self-hostable workspace. Its offline-first architecture, end-to-end encryption option, and no-vendor-lock-in philosophy make it the top choice for privacy-conscious individuals and organizations who value data sovereignty.
