Unison is a file-synchronization tool for POSIX-compliant systems and Windows. It allows two replicas of files and directories to be stored on different hosts or disks, modified separately, and then synchronized by propagating changes. The Flatpak version includes instructions for remote SSH usage. It is a mature open-source utility used by developers and power users for reliable bidirectional file syncing.
