BrowserStack

BrowserStack is a cloud-based testing platform that enables developers and QA teams to test websites and mobile applications across a wide range of real browsers, operating systems, and devices. By hosting real devices in the cloud, BrowserStack allows users to perform live, interactive testing and to run automated tests without maintaining an in-house device lab or local infrastructure. The service supports testing on desktops with major browsers (Chrome, Firefox, Edge, Safari) on Windows and macOS, as well as on mobile devices running iOS and Android.

The product lineup includes Live for manual testing in real browsers on real devices, Automate for running automated tests on remote browsers and devices (using Selenium and Appium-based workflows), and App Automate for testing native mobile apps. BrowserStack also provides features such as screenshots for quick visual checks and options for cross-device visual validation, along with integrations with popular CI/CD tools to fit into developer workflows.

Founded in 2011 by Ritesh Arora and Nakul Aggarwal, BrowserStack has grown into a widely adopted cloud testing service used by organizations of various sizes worldwide. It aims to accelerate cross-browser compatibility testing and shorten release cycles by providing scalable access to real devices and browser environments without the overhead of managing physical devices or local test infrastructure.
