spacedrive

Spacedrive keeps files on user devices with optional end-to-end encryption and no mandatory cloud uploads, as highlighted in the Privacy & Security section, ensuring data sovereignty.

Uses adaptive BLAKE3 hashing for deduplication and redundancy tracking across devices, enabling smart file management based on content rather than location, as described in the Content Identity System section.

Implements peer-to-peer synchronization with Iroh and QUIC for direct device connections and NAT traversal, eliminating central servers and single points of failure, per the Leaderless Sync principle.

Provides a consistent file manager experience across macOS, Linux, and planned Windows, iOS, and Android, with cloud integration via OpenDAL for services like S3 and Google Drive.

Allows previewing file actions for conflicts and space savings before execution, with durable jobs that survive interruptions, as outlined in the Transactional Actions feature.
