About Syncthing
Syncthing is an open source program that keeps folders in sync between your computers in real time. Files travel directly between your devices, not through a central service.
What it does
Syncthing watches the folders you choose and copies changes to the other devices you have approved. Each device is identified by a cryptographic certificate, and connections are encrypted. You can set it up on a local network, or let it find devices over the internet. A browser-based interface lets you add folders, manage devices and check progress.
Key features
- Sync folders between two or more computers
- Encrypted connections between approved devices
- No central server holds your files
- Web interface for setup and monitoring
- Runs on macOS, Windows, Linux and other systems
Who it's for
People who want to keep their own files on their own hardware, such as photographers moving images between a laptop and a desktop. It also fits developers and small teams that want a backup copy on another machine without paying for a cloud service.
Pricing and good to know
Syncthing is free and open source under the MPL-2.0 license. Because there is no central server, both devices must be online at the same time for changes to move, unless a third device relays them. Set your folder sharing carefully so that only the people you trust can see the files.
Highlights
- Sync folders between computers in near real time
- Approve each device before it can connect
- Encrypted transfers with no central storage
- Manage devices and folders from a browser
- Works across macOS, Windows and Linux
