CoopSync syncs your co-op game saves with friends through your own private GitHub repository. No cloud, no subscription — no third-party server ever sees your files.
Files live only in a private GitHub repo you own. No third-party server ever sees or stores them.
The presence service shows when a friend is in-game, without constantly polling GitHub — instant notification for a new save.
CoopSync finds your installed co-op games and their save files automatically — no manual paths.
