Syncthing is a free, open-source continuous file synchronization program that mirrors data across two or more computers in real time. Unlike traditional cloud services like Dropbox or Google Drive, it uses a architecture, meaning your files are never stored on a central server; they travel directly between your trusted devices. Where to Download the Syncthing Client
To start syncing, you must download and install the client on every device you wish to connect. Official and community-supported versions are available for nearly every major platform. Syncthing Made EASY
