Is there a solution to have synced save files on non cloud saves games?

[Mr. Miscellaneous]

For context, I'm syncing game saves from my PC to Steam Deck and vice verca.

Could use something like SyncThing[syncthing.net] to sync things between machines
This is 2 years old so no idea if it still works but at least a starting point

There is a SyncThing Decky Plug-in:

First install Decky then install the plug-in through Decky.
