About Google Chrome

Google Chrome is a web browser developed by Google. It is available for Windows, macOS, Linux, iOS and Android. Google Chrome was first released in 2008, built with free software components from Apple WebKit and Mozilla Firefox. Google Chrome has dominated the browser market share and stand on top when it comes to browser usage.

Google Chrome is based on Chromium, an open-source and free web browser. Chromium is managed by the Chromium Project and developers of the project have full rights to change the source code. But, Google Chrome has added some proprietary features; for example, it installs updates automatically and supports additional video formats.

Thanks to Chromium being open-source, many popular browsers have switched from their respective rendering engine to Chromium. That has eased the life of developers and testers globally by mitigating browser compatibility challenges.
