syncthing

Syncthing is a continuous file synchronization program that maintains synchronized copies of files across multiple computers without requiring a central server. It uses a peer-to-peer protocol to directly synchronize files between devices, prioritizing data safety and security through encryption and careful conflict resolution.

The tool operates automatically in the background once configured, requiring minimal user intervention for ongoing synchronization. It includes a web-based GUI for configuration and monitoring, with additional GUI implementations available for Windows, Mac, and Linux. Syncthing can run on common computing platforms and includes built-in automatic upgrade mechanisms with GPG-signed releases.

The synchronization focuses on individual users rather than enterprise deployments, making it suitable for personal file synchronization across laptops, desktops, and servers. Files are encrypted during transmission, and the system includes safeguards against data corruption. Docker deployment is supported, and the tool can be built from source using Go.
