Talky.io provides open source simple WebRTC solutions. Simply provide a url and launch to create a groupvideo chat -
talky.io 
Built entirely on open-source technologies (both our own code as well as great projects like Jitsi, Prosody, and restund).
Talky is made by an independent software team based in Richland, WA. We've open sourced a huge amount of the open-source technologies Talky is built on, like SimpleWebRTC and Otalk.
# Tips
Talky's control panel allows, but does not require, a name.
I get a federated wiki page which has a talky reference in it. The page is owned by you. When I select the talky reference it takes me to a page asking if I'm ready to talky but no actionable link or button other than a learn link.
Talky needs to use your camera. Click ALLOW to proceed.
Tip: Talky needs access to your camera. Chrome pops the question in the upper right of your browser window. Talky tries to bring this to your attention by blinking an arrow at the link but it isn't where you'd expect to look.
