Unfair competition

With the launch of Google Blink web engine on April 3rd, 2013, both projects Google Blink and AG Projects Blink from overlap massively in scope, nature and purpose. While the webkit fork can be used for more purposes than Blink SIP client, the explicit adoption of RTCWEB standards into blink fork of webkit, Google library competes direct with the purpose and addresses the same market of Blink SIP client using the same name.

Quote from

The goal of the RTCWEB protocol specification is to specify a set of protocols that, if all are implemented, will allow an implementation to communicate with another implementation using audio, video and data sent along the most direct possible path between the participants

Since the launch of Google fork search results about Blink SIP client have been flushed away, only Google relevant results appear.


  • Both projects have the same name
  • Both projects implement real time communications features (text chat, audio and video sessions)
  • Both projects are in the open source domain
