Our verdict: a capable open-source, local-first Notion alternative that keeps your data on your device — younger and faster-moving than Notion, with some security signals we could not independently confirm.
AppFlowy is an open-source Notion alternative that puts documents, Kanban boards, and customizable databases in one local-first workspace, available on Windows, macOS, Linux, iOS, Android, and the web.
It is local-first and self-hostable, so your data stays on your device or your own server and works fully offline; optional managed cloud and AI plans are available. It is a younger, fast-moving project compared with Notion's polish.
