Syncthing is a free and open-source file synchronization tool for Windows that synchronizes files directly between computers and other supported devices.
Unlike traditional cloud storage services, Syncthing uses a decentralized peer-to-peer approach, so files do not need to be stored on a central cloud server. Connections between devices are encrypted, and only authorized devices can participate in synchronization.
Key Features
-
Peer-to-Peer Sync: Synchronize files directly between connected devices without relying on centralized cloud storage.
-
Encrypted Transfers: Uses TLS encryption to protect data during synchronization.
-
Device Authentication: Each device has a unique identity, and only authorized devices can connect.
-
Cross-Platform: Supports Windows, macOS, Linux, and other platforms.
-
Web Interface: Manage devices, folders, and synchronization settings through a web-based interface.
-
Automatic Synchronization: Automatically keeps selected folders synchronized across connected devices.
-
File Versioning: Can preserve previous versions of files when configured.
