Syncthing

Syncthing is a free and open-source peer-to-peer file-synchronization software for Windows PC! 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.

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

Features and Highlights

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.

Web GUI
Configure and monitor the tool via a responsive and powerful interface accessible via your internet browser.

Portable
Works on macOS, Windows, Linux, FreeBSD, Solaris, and OpenBSD. Run it on your desktop computers and synchronize them with your server for backup.

Simple
The app 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.
