Google Chrome is a freeware web browser developed by Google. It used the WebKit layout engine until version 27 and with the exception of its iOS releases, from version 28 and beyond uses the WebKit fork Blink. It was first released as a beta version for Microsoft Windows on September 2, 2008, and as a stable public release on December 11, 2008.

As of June 2016, StatCounter estimates that Google Chrome has a 62% worldwide usage share of web browsers as a desktop browser. It also has 50% market share across all platforms combined, because it's also the most popular browser for smartphones. Its success has led to Google expanding the 'Chrome' brand name on various other products such as the Chromecast.

Google releases the majority of Chrome's source code as an open-source project Chromium. A notable component that is not open source is their version of the built-in Adobe Flash Player, called Pepper Flash Player.
