Blink is a browser engine developed as part of the Chromium project with contributions from Google, Meta, Microsoft, Opera Software, Adobe, Intel, IBM, Samsung, and others. It was first announced in April 2013.

Naming

Blink's naming was influenced by a combination of two major factors: the connotations of speed, and a reference to 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.

History

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

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. Aside from these planned changes, Blink initially remained relatively similar to WebCore.

By commit count, Google was the largest contributor to the WebKit code base from late 2009 until 2013 when they started work on their fork, Blink.

Internals

Blink engine has the following components:

Public API

Blink exposes a public API that allows browsers such as Chromium to interact with Blink while remaining insulated from internal changes to the browser engine.

Frameworks

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

Platforms

Chromium Blink is implemented on seven platforms: Windows, macOS, Linux, ChromeOS, Fuchsia, Android, and Android WebView.

Blink is also unofficially supported on FreeBSD and OpenBSD.

iOS versions of Chromium continue to use the WebKit WebCore renderer.
