TestMu AI (formerly LambdaTest) review

TestMu AI, the new name for LambdaTest, ranks third on value and breadth. Automation is priced per parallel session with unlimited minutes and users, starting at $29 a month billed annually for Chrome, Firefox and Edge on Linux and $79 for Desktop All OS, which adds Windows and macOS, JavaScript frameworks such as Playwright and Cypress, and access to the Live plan. Virtual Automation Cloud at $139 adds emulators, simulators, Appium, Espresso, XCUI and Detox, and Real Device Plus at $199 covers real phones with biometrics, GPS mocking, camera injection and Smart TV testing. Each paid plan bundles 2,000 SmartUI screenshots and 300 minutes of the HyperExecute orchestration cloud, and the KaneAI agent writes tests from natural language. The catch is that the plans are separate tracks: real device plans do not include desktop or virtual devices, so mixed coverage means two plans or Enterprise.

Who it is for

Teams that want a low-cost browser automation cloud with the option to add virtual or real devices later.
