Google Chrome browser is a free software web browser developed by Google. It was first released in 2008 for Microsoft Windows and later ported to Linux, Mac OS, IOS and Android. Google browser is also the main component of chrome operating system, which can be used as a platform to run web applications.

Google publishes most of Chrome's source code as an open source project of chromium. The built-in Adobe Flash player is a well-known non open source component (disabled by default by chrome since September 2016). Chrome used the WebKit layout engine until version 27. Starting with version 28, all chrome ports, except IOS ports, use blink (a branch of the WebKit engine).

As of February 2017, StatCounter estimated that Google's desktop browser usage in web browsers accounted for 62% of the world's total. Because it's also the most popular browser on smartphones, it also has 52% of the total market share of all platforms. Its success has allowed Google to expand its "Chrome" brand name on a variety of other products, such as chromecast, chromebook, chromebit, chromebox and chromebase.
