Trilium is an excellent option, however, the original project is no longer maintained. There is a new community fork that is active here: https://github.com/TriliumNext/Notes

+1 for the open source option: Trilium The project is being maintained here: https://github.com/TriliumNext/Notes

You can always export all of your notes in markdown format, but the notes are always saved in a database.

perfect! This project may help your migration. I’m pretty sure the script is broken currently, but if you tinker with it a bit, perhaps it could speed up your migration: https://github.com/meichthys/onenote-html-export

Ok, thanks for your feedback!

Glad to hear! Would you mind sharing how you migrated from OneNote? We would like to make that migration path easier for future migrants.

Currently there are no significant new features (although we do now offer a windows exe installer). The initial stable release was mostly back-end changes intended to make future development easier and more maintainable. Keep you’re eye out though, since there are some new features in the works (2FA, Internationalization, and maybe some mobile improvements).

I’ve never quite understood why this is such a non-starter for most people. I just simply set up a script to export my Trilium notes to Nextcloud as flat files so I can still read my notes anywhere even without a Trilium client. Trilium also allows you to edit the notes with an external editor, and then you can just re-import the note to update the note in Trilium.
