AppFlowy
A self-hosted Notes & Knowledge app you can run on your own server.
AppFlowy is an open, self-hosted notes and knowledge-base application — you install it on your own hardware and keep full control of your data. Because it runs on infrastructure you control, your data stays with you and there is no subscription required to keep using it.
Development happens in the open on GitHub; the repository has collected 76.5K stars so far. Repository activity was last recorded on Jun 26, 2026, and the project is classed as actively maintained in our snapshot.
Before you switch
Switching notes tools is mostly about formats. Prefer projects that store notes as plain Markdown or offer a clean export, so you are never locked in. Migrate one notebook first, live in it for a week, and only then move the archive.
Like every project listed on SelfHosted, AppFlowy is developed in the open — you can read the code, follow development, and even contribute. Check the system requirements and the project’s own documentation linked on this page before installing.
