| description.long | An open-source platform for file synchronization and sharing designed for self-hosted deployment, with native clients for desktop and mobile devices. | Unison maintains multiple copies of files and directories on different hosts or disks, automatically propagating non-conflicting changes between replicas. It detects conflicting updates, works offline after synchronization, and runs as a user-level program without requiring kernel modifications or elevated privileges. |
