We have been making great progress on the ORTC Lib, see our 2015 year-end update here!


Object RTC (ORTC) is a free, open project that enables mobile endpoints to talk to servers and web browsers with Real-Time Communications (RTC) capabilities via native and simple Javascript APIs. The Object RTC components are being optimized to best serve this purpose.

Our mission: To enable rich, high quality, RTC applications to be developed in mobile endpoints and servers via native toolkits, simple Javascript APIs and HTML5. It is also a mandate that Object RTC be compatible with WebRTC.

The Object RTC initiative is a project supported by Hookflash, Microsoft, Google and others. This page is maintained by the Hookflash team.

Call for Implementations

The W3C ORTC Community Group has completed the work required on the initial API which now provides the constructs for implementations.  We would like to to hear from the community regarding their proposed and ongoing projects.

As an example, the Hookflash team maintains the ORTC Library, the Microsoft team is making advancements on ORTC in Internet Explorer as discussed in the last Community Group meeting on October 14 2014. Google is also making progress with recent pull requests into the webrtc 1.0 source repo, where we are seeing some of the ORTC API elements move into Chrome source code.
