I assume you want to self host in order to sync locally, right? If that's the case, you can use Obsidian with git plugin and you get sync + versioning (all what git offers).

Which git plugin do you like? And have you used the plugin from more than one machine to a repo more than one machine also syncs with?

Sync is premium since some versions. Before it was free, you had only to provide a S3 bucket or a webdav location

I use syncthing to sync my obsidian vault which is also a git repository between linux, mac and windows.

Works great!
