Description

Syncthing is a continuous file synchronization program. It synchronizes files between two or more computers in real time. Syncthing is open source and runs on Windows, macOS, Linux and FreeBSD. Its source code is published on GitHub.

It also works on Solaris, OpenBSD and many other systems. Your data is stored only on your own computers, and there is no central server. Communication between devices is encrypted with TLS. Each device is identified by a cryptographic certificate, and only devices you have allowed can connect.

You configure and monitor it through an interface in your browser. It works over a local network and the Internet without needing IP addresses or advanced configuration.
