Syncthing is a free and open source tool that keeps folders identical across two or more of your own devices. It suits Mac users who want files to follow them between a desktop, a laptop and other machines without handing copies to a cloud service.

Key Features

• Continuous sync keeps shared folders up to date on every connected device
• Transfers go directly between your devices with encryption and no central storage server
• Works across macOS, Windows, Linux and other platforms, so mixed setups sync together
• File versioning options can keep older copies when files change or get deleted
• Control and monitor everything from a clear web interface in your browser
