| description.long | Seafile is an open-source file management and collaboration platform available as both a self-hosted solution and cloud service. It combines core file synchronization and sharing capabilities with advanced features including metadata management, AI-powered organization, document collaboration, and team knowledge bases. | Unison is an open-source utility that maintains two replicas of files and directories across separate hosts or storage devices, automatically propagating non-conflicting changes while detecting conflicting updates. It works over internet connections including slow links, and allows offline access to already-synchronized data. |
