What are Spacedrive and Syncthing?

Spacedrive

Spacedrive is an open-source, cross-platform file manager written in Rust, built around a virtual distributed filesystem (VDFS). It indexes and organizes files across multiple devices and storage locations from a single native app.

  • Virtual distributed filesystem
  • Indexes files across devices
  • Cross-platform native app

Syncthing

Syncthing is a continuous file synchronization program that syncs files between two or more devices directly, without a central server. It is ideal for individuals who want private, serverless sync across their own machines. It is distributed as a single binary and also runs well in Docker.

  • Fully decentralized peer-to-peer sync
  • TLS-encrypted transfers
  • No cloud account required
  • Cross-platform with mobile apps
