Open source Notion alternative

AppFlowy is the closest open source alternative to Notion: docs, databases, kanban boards, and wikis, all self-hosted so your data stays on your machines. It runs as a desktop app (Windows, macOS, Linux) with an optional cloud sync, and the editor experience is polished.
