'''Blink''' is a [[browser engine]] developed as part of the [[Free and open-source software|free and open-source]] [[Chromium (web browser)|Chromium]] project. Blink is by far the most-used browser engine, due to the [[Web browser#Browser market|market share]] dominance of [[Google Chrome]] and the fact that [[Chromium (web browser)#Browsers based on Chromium|many other]] browsers are based on the Chromium [[source code|code]].
'''Blink''' is a [[browser engine]] developed as part of the [[Chromium (web browser)|Chromium]] project. To create the [[Google Chrome|Chrome]] browser, [[Google]] chose to use [[Apple Inc.|Apple]]'s [[WebKit]] engine. However, Google needed to make changes to the WebKit code to support its novel multi-[[Process (computing)|process]] browser architecture,<ref name="blink_announcement"/><ref name="blink_ars">{{cite web |first=Peter |last=Bright |title=Google going its own way, forking WebKit rendering engine |url=https://arstechnica.com/information-technology/2013/04/google-going-its-own-way-forking-webkit-rendering-engine/ |website=[[Ars Technica]] |publisher=[[Conde Nast]] |date=3 April 2013 |access-date=9 March 2017}}</ref> and the increasing divergence from Apple's version led Google to officially [[Fork (software development)|fork]] its version as Blink in 2013.<ref name="blink_announcement"/><ref name="blink_ars"/> ▼

Much of the unwanted WebKit code was used for features that Google implemented differently in [[Chromium (web browser)|Chromium]], such as [[Sandbox (computer security)|sandboxing]] and the multi-process model. These parts were altered from the beginning. Blink also deprecated [[CSS]] [[vendor prefix]]es, phasing them out, and new experimental functionality is instead enabled on an opt-in basis.<ref>{{cite web |title=Blink Developer FAQ |website=The Chromium Projects |url=https://www.chromium.org/blink/developer-faq#TOC-Will-we-see-a--chrome--vendor-prefix-now- |access-date=22 October 2014}}</ref>

* [[Document Object Model|DOM]], [[HTML DOM]] and [[CSS]] rendering engines
* [[Web IDL]] implementation
* [[Skia Graphics Engine|Skia]] Graphics engine — makes calls to an underlying Graphics Library (like [[OpenGL]], [[Vulkan]], [[DirectX]] etc) which depends on the platform
=== 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.<ref>{{Cite web |title=Blink Public API |url=https://chromium.googlesource.com/chromium/src/+/HEAD/third_party/blink/public/README.md |access-date=2022-08-15 |website=chromium.googlesource.com}}</ref>
