Google, on Blink:
WebKit is a lightweight yet powerful rendering engine that emerged out of KHTML in 2001. Its flexibility, performance and thoughtful design made it the obvious choice for Chromium’s rendering engine back when we started. Thanks to the hard work by all in the community, WebKit has thrived and kept pace with the web platform’s growing capabilities since then. […] However, Chromium uses a different multi-process architecture than other WebKit-based browsers, and supporting multiple architectures over the years has led to increasing complexity for both the WebKit and Chromium projects. This has slowed down the collective pace of innovation – so today, we are introducing Blink, a new open source rendering engine based on WebKit.
Mozilla, on Servo:
Mozilla’s mission is about advancing the Web as a platform for all. At Mozilla Research, we’re supporting this mission by experimenting with what’s next when it comes to the core technology powering the Web browser. We need to be prepared to take advantage of tomorrow’s faster, multi-core, heterogeneous computing architectures. That’s why we’ve recently begun collaborating with Samsung on an advanced technology Web browser engine called Servo.
Oh, thank every god! More rendering engines is exactly what the world needs. I do so enjoy testing every Web page I build in 78 different browsers. Now I can test every page in 674 different browsers! Huzzah!
