Blink is a web browser engine developed as part of the Chromium project[2] by The Chromium Project with contributions from Google, Opera Software ASA, Intel, Samsung and others.[3][4] It was first announced in April 2013.[5]


It is a fork of the WebCore component of WebKit[6] and is used in Chrome starting at version 28,[7][8] Opera (15+),[7] Amazon Silk and other Chromium-based browsers and frameworks.

Much of WebCore's code is used for features which Chrome implements differently (such as sandboxing and the multi-process model). These parts were removed from the Blink fork, which made it simpler, and gave greater flexibility for adding new features. The fork will also deprecate vendor prefixes; experimental functionality will instead be enabled on an opt-in basis.[9] Aside from these planned changes, Blink currently remains relatively similar to WebCore.[8] By commit count, Google has been the largest contributor to the WebKit code base since late 2009.[10]

Blink's naming was influenced by the non-standard presentational blink HTML tag, which was introduced by Netscape Navigator, and supported by Presto and Gecko-based browsers until August 2013.[2][11][12]


Several projects exist to turn Chromium’s Blink into a reusable software framework for other developers:
