Syncthing is an open-source, free file synchronization application, written in GO programming language, available for almost every operating system Linux, Unix, Windows, Mac, BSD, Android and iOS. It can sync between device that are present on the local network (no Internet required), or between remote devices over the Internet. It is secure and safe since both things are built-in into the application.
Syncthing replaces proprietary sync and cloud services with something open, trustworthy and decentralized. Your data is your data alone and you deserve to choose where it is stored, if it is shared with some third party and how it's transmitted over the Internet. It should be safe from data loss, protecting the user's data is priority. Developers took reasonable precaution to avoid corrupting the user's files.



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.
