What is BrowserStack and what is it used for?
BrowserStack is a cloud testing platform that runs web and mobile applications on real browsers and devices, so the team does not have to build or maintain its own device lab.
The vendor advertises more than 35,000 real iOS and Android devices and more than 3,500 browser and operating system combinations for testing. The count varies across the vendor's own pages (some cite 30,000), so treat the numbers as an order of magnitude.
The platform is split into products: Live for manual browser testing, App Live for apps on real devices, Automate and App Automate for automated tests, Percy for visual testing, plus accessibility and test management tools.
QA and development teams use BrowserStack to find behavior that breaks across browsers and problems that only appear on a specific device, before the failure reaches the user.
