For my work notes, which are not allowed to be stored outside company resources, I have set up a git repo and use a plugin that auto commits.

It does not work well for sharing to a mobile env but works great for desktop.

I use syncthing to sync my notes between my PC and Laptop. It works pretty well.

If you’re on Apple devices only, then iCloud sync is free and works on all devices.

I no longer use Obsidian, so not sure what’s the best option for e.g. Linux <-> iOS sync except their service.

I'm quite fond of the obsidian-gut plugin and syncing to a private Forgejo instance.
