What is "browserstack"

BrowserStack is a cloud-based cross-browser testing tool that enables developers to test their websites across various browsers on different operating systems and mobile devices, without requiring users to install virtual machines, devices or emulators.

The subscription-based service was founded by Indian Institute of Technology graduates Ritesh Arora and Nakul Aggarwal in 2011 in Mumbai, India and since then it has gained widespread acceptance in the web development community worldwide to test the layout and performance of a website from their desktop browsers. As in August 2015, BrowserStack has 30,000 paid users and 520,000 registered developers in more than 135 countries.

In October 2015, BrowserStack was recognised as Bootstrap Champ by Economic Times Startup Awards.
