Blink is a browser engine developed as part of the free and open-source Chromium project.

To create Chrome, Google chose to use Apple's WebKit engine.

[2] However, Google needed to make substantial changes to the WebKit code to support its novel multi-process browser architecture.

[6] By commit count, Google was the largest contributor to the WebKit project from late 2009 until the fork in 2013.

[7] One of the first changes of the new fork was to deprecate CSS vendor prefixes, including WebKit's; experimental Blink functionality is instead enabled on an opt-in basis.
