Why Hello?
Its 2018, WebRTC is natively supported in all desktop & mobile browsers but still most major players (Hangouts, skype, Appear.in etc) ask you to download their app to use the service.
Hello
Hello is a video chat app that works in most major desktop & mobile browsers. No Signup. No Downloads. Just video chat.
Hello uses WeBRTC for video communication and a socket.io server that serves as a signaling server. It uses WebRTC mesh when more people is added to the call, it means each video stream in a group call is a separate P2P connection. There is no hard limit on the number of people in the group video call, but the quality of the call will decrease when more than 5 people join the call.

If you are here for checking the p2p video call w/o signaling server, head over to the gh-pages branch. And check out the demo here https://vasanthv.github.io/hello/.
