Seafile: Open-Source File Sync and Sharing Platform with Team Collaboration

What is Seafile?

Seafile is an open-source file hosting, sync, and sharing platform designed for team collaboration and file management. Built with focus on security, privacy, and ease of deployment, Seafile provides file synchronization, sharing, and collaborative editing capabilities similar to Dropbox but with emphasis on data ownership and control. Over 100,000 organizations worldwide use Seafile for secure file management and team collaboration while maintaining complete data ownership.

Unlike Dropbox ($11.99-16.58/user/month) or Google Drive ($12/month per user) where files are stored on third-party servers with limited control, Seafile enables organizations to host file management on-premises or self-hosted infrastructure. Complete encryption, privacy controls, and no per-user licensing make Seafile ideal for enterprises with strict data governance.

Seafile serves as the file management and collaboration hub. Teams organize files into libraries with permission controls. Documents are shared and collaborated on in real-time. Files sync across devices automatically. Version history enables file recovery and audit.
