BrowserStack

BrowserStack offers a Cloud-based service for testing across 2000+ real devices and browsers, covering new and old versions of IE, Edge, Safari, Chrome and Firefox on Windows and macOS.

This offers a native experience – real browsers on real machines with media streaming, developer tools, keyboard shortcuts and much more.

Services include Live for real-time cross-browser testing, Automate for a Cloud-based Selenium service, and Percy for automated visual testing, capturing screenshots, comparing them against the baseline and highlighting visual changes.
