why would you host anything? that’s just an app. QOwnNotes (stupidest name ever) stores .MD files that you can syncthing, rsync, copy, edit externally, whatever, allowing you never to be locked-in again. all the toolboxes can be turned off, netting you a UI that looks like apple’s notes.



that’s what syncthing is for. you can set it up to sync the Notes folder to your other devices in a read/write way or just one way, so you got your central repo.
also, qown has nextcloud notes sync built in.
