Syncthing

Syncthing is an open-source file synchronization tool that allows users to securely and efficiently sync files and folders across multiple devices. It operates in a peer-to-peer fashion, meaning there's no central server involved. Users can use Syncthing to keep their data up-to-date on different computers or mobile devices, ensuring that files are consistently mirrored and available, while maintaining control over their data privacy and security.

This will run Syncthing under http://localhost:9060 inside your network
