Nudge

Nudge is a small CLI tool for sending data from one computer to another via UDP. The project was strongly inspired by the croc and qft projects. The aim is to enable simple peer-to-peer data transfer, so that the data is not sent via a central server, but transferred directly peer-to-peer,

Server

The server acts as a relay server. This server should be publicly accessible (i.e. by every peer). The relay server manages the communication and connects the peers with each other.

You can use the following public server: new.d2a.io:4000 (no guarantees for availability).
