"We have tripled our tests and are now executing tests in less than 2 hours with 78% Faster Test Execution"
"We figured out a more efficient way to monitor system health and resolve failures earlier in lower environments."
"TestMu AI has significantly boosted our testing speed, is easy to implement, and provides exceptional support."
"With 70% faster test execution, TestMu AI helped us achieve faster time-to-market and enhanced CX."
Mobile Testing Is Harder Than Web Testing. By a Lot.
Too Many Devices to Cover
Android spans tens of thousands of device and OS combinations. No in-house lab covers them all, and the gaps are where bugs hide.
Selectors Decay Every Release
Appium and Espresso tests are brittle. One minor UI tweak silently kills 30% of your suite and erodes trust in the runs.
Touch-First by Nature
Real users interact through the screen and device hardware. Tooling built for the web cannot reproduce how that behaves.
Build, Queue, Wait, Retry
Mobile CI is slow. Long install times and small device pools make developers ship blind while results lag behind.

Everything Mobile App Testing Actually Requires
Native Gestures and Biometrics
Pinch, swipe, and long press. Simulate Face ID, Touch ID, and fingerprint prompts. Handle deep links and app switching.
Network Throttling
Simulate 3G, 4G, 5G, offline, and lossy connections. Validate retry logic and offline-first behavior on real radios.
Geolocation Testing
Test from 170+ regions with GPS and IP spoofing. Validate region-locked features and localization end to end.
Full Session Telemetry
Device logs, network HAR, app logs, and video on every session. Each failure ships with a complete diagnostic trail.
Parallel Execution
Run hundreds of tests across real devices at once. HyperExecute orchestrates the queue and cuts suite time sharply.
Secure Tunneling
Test localhost, staging, and internal builds from the cloud. SSO and SOC 2 Type II ready for regulated teams.
LambdaTest is now TestMu AI
On January 12, 2026, LambdaTest evolved into TestMu AI, the same trusted 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. The platform is AI-native, with autonomous agents that plan, author, execute, analyze, and optimize tests.
The next era of the world's first fully Autonomous Agentic AI Quality Engineering Platform is here.

Some love from our customers!
Debugging Specific Devices Got a Lot Easier. I liked being able to select a specific device and browser combination to troubleshoot issues reported by customers...

86000 + Minutes & 1300 + Tests Thank you 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.
