this has been around for four years?! Awesome! Would like to see the faq more easily accessible for troubleshooting. Was not able to send jpgs the first few tries
There have been hundreds of these type of WebRTC file transfer sites. They never seem to work very well.
It looks like this one is sending all the traffic through a single nodeJS worker. Not surprising.
It's just the signalling server to exchange ICE candidates. Once the connection has been made between two devices, the traffic is direct...unless they are on two different networks and/or firewalled, then you would need a TURN server to relay traffic through.
Ah, thanks for taking a closer look and commenting
