Trilium Notes
A self-hosted Notes & Knowledge app you can run on your own server.

Development happens in the open on GitHub; the repository has collected 37.8K stars so far. Repository activity was last recorded on Sep 12, 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, Trilium Notes 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.
