BrowserStack
BrowserStack is a browser and device cloud. It gives your team access to 3,000+ real browsers and devices for manual testing, Selenium/Cypress/Playwright execution, and visual regression via Percy.
It is the industry standard for cross-browser testing. If your product needs to work on Safari 14, Firefox ESR, and Chrome on Android 11 — BrowserStack is the tool for that.
BrowserStack does not generate tests for you. It does not do API testing. It does not review your pull requests. It is infrastructure for running tests you already have, across browsers you don't own.
