- End-to-end encrypted sharing
- Fine-grained access groups
Seafile
Seafile is a file sync and share platform built around a reliable, high-performance file storage engine. It is well suited for users and organizations that prioritize fast, reliable sync of large libraries. It is typically deployed via Docker Compose or on bare metal.
- Fast block-level sync engine
- Client-side encrypted libraries
- Reliable handling of large file sets
- Desktop, mobile and web clients
