What is LambdaTest?

LambdaTest is a cloud testing platform: thousands of browser and operating system combinations, real phones and tablets, and a grid that runs Selenium, Playwright and Cypress tests in parallel. It was founded in 2017.

It answers the question every agency gets: does it work on the browser the client uses?

How I use LambdaTest

LambdaTest was part of QA at TeamQ, next to Selenium, so client sites were checked on the browsers and devices their visitors actually used before they went live.
