LambdaTest is now TestMu AI

On January 12, 2026, LambdaTest evolved into TestMu AI, the same trusted real iPhone testing cloud, upgraded for the AI era.

Now a full-stack agentic AI quality engineering cloud, it automates end-to-end testing across web, mobile, and AI apps with autonomous agents that plan, author, execute, analyze, and optimize tests.

LambdaTest is now TestMu AI

The next era of the world's first fully Autonomous Agentic AI Quality Engineering Platform is here.

Test Website on iPhone Safari Without Owning it

Open Safari on a real iPhone in your browser, load any URL, inspect with DevTools.

  • Real WebKit on real iOS, the only way to catch Safari iOS-only render bugs.
  • DevTools inspection, viewport rotation, and network throttling per session.
  • Screenshots and full session recording on every iphone test run.

iPhone Simulator vs Real iPhone Testing

An iPhone simulator runs a virtual iOS image on a Mac and approximates the UI only.

Only a real iPhone exposes the WebKit, biometric, GPS, and thermal behavior your users hit.

86000 + Minutes & 1300 + Tests Thank you @testmuai for helping us to tackle client requirement of running automated tests in multiple mobile browsers. With this, we had the flexibility to run multiple tests in parallel and our tests became scalable by widening the test coverage and reducing the time of execution. We highly recommend TestMu AI if you are looking for a cost-effective method to scale your tests, Thanks again and we are looking forward to leverage this to other projects as well.#lambda #efficiency #costoptimization #testingtools #testvox #crossbrowsertesting #crossbrowsercompatibility #testautomation
