Why WebRTC?

WebRTC is an open source standard used to embed communications into web-based applications for a completely customizable experience. Users can join voice or video calls with a single click and provide contextual information with integrations directly to your systems of record. Twilio built a platform on top of WebRTC so that you can take full advantage of all these features when building applications.
