What is it?

Seafile is an open source cloud storage system for file sync, sharing and teamwork. Files are organized into libraries, and each library can be synced separately or encrypted with a password chosen by the user. Users can also create groups and share folders with other users or groups.

The sync engine transfers only changed content, resumes interrupted transfers, and resolves file conflicts based on history rather than timestamps. A virtual drive client gives access to cloud files with on-demand sync, and desktop syncing supports client-side encryption.

Beyond sync, Seafile adds metadata management with custom file properties, tags with parent-child hierarchy, and views including table, Kanban, gallery, map and statistics. It also offers integration with OnlyOffice and Collabora, a built-in collaborative document editor (SeaDoc), wiki knowledge bases, and Excalidraw for whiteboards.
