BrowserStack

BrowserStack is a cloud-based cross-browser testing platform founded in 2011 by Ritesh Arora and Nakul Aggarwal, headquartered in Mumbai and San Francisco, providing access to over three thousand real browsers and operating systems including Chrome, Firefox, Safari, Edge, Internet Explorer, and mobile browsers on iOS and Android devices, enabling developers and QA teams to test websites and web applications across diverse browser, device, and operating system combinations without maintaining internal device labs, adopted by over fifty thousand customers including Microsoft, Twitter, Disney, and Amazon. The live testing provides interactive access to real browsers running on actual operating systems through remote desktop connections, enabling manual testing of websites across Windows, macOS, Linux, iOS, and Android with any browser version, including debugging with Chrome DevTools and Web Inspector, screenshot capture, and session recording for bug reporting and reproduction. The automated testing integrates with Selenium, Cypress, Playwright, Puppeteer, Espresso, and XCUITest frameworks, enabling running existing test suites across hundreds of browser and device combinations in parallel through the cloud infrastructure, with test reporting including video recordings, screenshots, network logs, console logs, and text logs for each test execution. The visual testing through Percy provides automated visual regression testing that captures screenshots of web pages and mobile screens across browsers and viewports, comparing against baselines and highlighting visual differences for review. The local testing enables testing of internal, development, and staging environments through secure tunnels between the local network and the BrowserStack cloud. The App Live and App Automate provide mobile application testing on real devices. Designed for QA engineers, frontend developers, and testing teams.
