Google Chrome is actually a freeware web browser developed by Google. It was first released in September 2008, for Microsoft Windows, and was later ported to Linux, macOS, Android and iOS. Google Chrome is also the primary element of Chrome OS, where it serves as a platform for running web apps.
Google releases the vast majority of Chrome's source code as the Chromium open source project; however, Chrome itself is actually proprietary software. One component which isn't open source is actually the built in Adobe Flash Player (that Chrome has disabled by default since September 2016). Chrome used the WebKit layout engine until version twenty seven. As of version twenty eight, all Chrome ports except the iOS port use Blink, a fork of the WebKit engine.
