Syncthing is a serverless, peer-to-peer file synchronization tool. It is often compared to Dropbox. However, unlike Dropbox, there is no central server with Syncthing; your devices talk directly to each other to sync data. Syncthing has various effective methods for firewall traversal, including public relays for the worst case. All Syncthing traffic is fully encrypted and authenticated.
