The browser world is about to see another shakeup as both Google announced they're going to switch to a new rendering engine. Google currently uses WebKit, an open-source rendering engine used by Safari and a bunch of other browsers. In an effort to further streamline its Chrome browser, Google decided it will fork WebKit by introducing Blink, a new open-source rendering engine based on WebKit.
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.

In the short term, Blink will bring little change for web developers. The bulk of the initial work will focus on internal architectural improvements and a simplification of the codebase. For example, we anticipate that we’ll be able to remove 7 build systems and delete more than 7,000 files—comprising more than 4.5 million lines—right off the bat. Over the long term a healthier codebase leads to more stability and fewer bugs.
