Ludusavi

A cross platform savegame synchronization tool that works on windows/linux/macos.
It can integrate with various backends like cloud storage or syncthing.
It can be installed on the steam deck.

NOTE:

synchronization uses absolute paths

it's primarily designed around backing up one computer's savegames to restore on itself.
there is a redirect feature that you can use to synchronize between ex. windows and wine installs.
but you'll need to configure it for every game.

It appears bidirectional synchronization is broken, but you can create it yourself. with two complementing redirects.
