When people think about WebRTC, they think about video calls inside a web browser. WebRTC is much more than that. WebRTC can be used to create fundamentally better experiences by embedding live, peer-to-peer communications in SaaS products, mobile apps, and websites. But what is the state of WebRTC today? What does it take for a business to really reap the benefits? My slide deck from the session I gave at Twilio's Signal event May 2015.

5. Both
19/5/2015 5
WebRTC is both an open source project (=Software Stack) and a
standard specification (=Browser Tech)
webrtc.org
• The open source project
• Holds an implementation of the
WebRTC specification
• Can be used by anyone for
anything
And also openWebRTC.io
WebRTC 1.0
• The standard specification
• Not yet completed
• Handled by the IETF and W3C
