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, Notesnook 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.
