Secure & Private

  • Private. None of your data is ever stored anywhere else other than on your computers. There is no central server that might be compromised, legally or illegally.
  • Encrypted. All communication is secured using TLS. The encryption used includes perfect forward secrecy to prevent any eavesdropper from ever gaining access to your data.
  • Authenticated. Every node is identified by a strong cryptographic certificate. Only nodes you have explicitly allowed can connect to your cluster.

Open Development


Easy to Use

Syncthing is still in development, although a large number of features have already been implemented:

  • Web GUI. Configure and monitor Syncthing via a responsive and powerful interface accessible via your browser.
  • Portable. Works on Mac OS X, Windows, Linux, FreeBSD and Solaris. Run it on your desktop computers and synchronize them with your server for backup.
  • Simple. Syncthing doesn't need IP addresses or advanced configuration: it just works, over LAN and over the Internet. Every machine is identified by an ID. Just give your ID to your friends, share a folder and watch: UPnP will do if you don't want to port forward or you don't know how.
  • Powerful. Synchronize as many folders as you need with different people.
