Blink is a browser engine developed as part of the Chromium project (since 2013)[2] with contributions from Google, Facebook, Microsoft, Opera Software, Adobe, Intel, IBM, Samsung, and others.[3][4] It was first announced in April 2013.[5]

Naming[edit]

Blink's naming was influenced by the non-standard presentational blink HTML element, which was introduced by Netscape Navigator, and supported by Presto- and Gecko-based browsers until August 2013. Blink has, contrary to its name, never functionally supported the element.[2][6][7]

History[edit]

Blink is a fork of the WebCore component of WebKit,[8] which was originally a fork of the KHTML and KJS libraries from KDE.[9][10] It is used in Chrome starting at version 28,[11][12] Microsoft Edge starting at version 79,[13] Opera (15+),[11] Vivaldi, Brave, Amazon Silk and other Chromium-based browsers and frameworks.

Much of WebCore's code was used for features that Google Chrome implemented differently such as sandboxing and the multi-process model. These parts were altered for the Blink fork, and although slightly bulkier, it allowed greater flexibility for adding new features. The fork also deprecates CSS vendor prefixes; existing prefixes will be phased out and new experimental functionality will instead be enabled on an opt-in basis.[14] Aside from these planned changes, Blink initially remained relatively similar to WebCore.[12]

By commit count, Google has been the largest contributor to the WebKit code base since late 2009.[15]

Internals[edit]

Blink engine has the following components:[16]

Frameworks[edit]

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

  • Microsoft Edge WebView2 is a framework that allows developers of Windows apps to implement a desktop app using web technologies, replacing the older Trident based webview.
  • DotNetBrowser is a proprietary .NET Chromium-based library that can be used to use Chromium capabilities in a wide range of .NET applications, including desktop and server solutions.[27][better source needed]

Platforms[edit]

Chromium Blink is implemented on six platforms: Windows, macOS, Linux, Chrome OS, Android, and Android WebView.

iOS versions of Chromium continue to use its parent renderer, WebKit WebCore.[28]
