Keepass2Android can sync over ssh (sftp), Nextcloud and many other others. I'm sure you'll find something that works for you.

I just use SyncThing to distribute my KeePass vault to exactly and only those devices where I need it. Works great for me. YMMV depending upon your needs.

Another SyncThing user here, it works well with KeePass.

Heads up if you're using this on Android

Maybe just use syncthing-fork

KeePassXC with Nextcloud client for Android is a perfect match for me. Using it for years with zero problems.

If you want to stay with the convenience of cloud without going back to sync conflicts due to moving a file around, Proton Pass is GPLv3 although I don't personally know what the self hosting story is like if they were to rug pull

Still astounds me anything from proton is recommended years after 'their' vpn was made by tesonet/nordvpn[0] which also owns a botnet/data-mining company[1]

I really want to use KeePass and its ecosystem but the password sharing story isn't great there. I and wife have a lot of shared passwords and Bitwarden works really good for that. So, I don't know what's a good viable alternative for us.
