AppFlowy

AppFlowy is an open source, AI-powered collaborative workspace that serves as a privacy-friendly alternative to Notion, Coda, and ClickUp. Built with Flutter and Rust, it lets you build pages, databases, kanban boards, calendars, and grids — all stored locally or on infrastructure you control.

Unlike Notion, AppFlowy does not lock your data behind a vendor. You can self-host the AppFlowy-Cloud backend, sync across devices, and extend the app with custom plugins written in Dart or Rust. The recent releases add AI features such as automatic page summaries, smart writing assistance, and natural-language database queries — all backed by bring-your-own-model support so the data never leaves your environment.

AppFlowy targets individuals and small teams who want the productivity of a modern workspace without giving up ownership of their data. It is suitable for personal note-taking, team wikis, lightweight project management, and content planning.
