Everything you need to test on mobile,
without touching a phone.
See exactly how your website renders on any mobile browser, on any device.
Run your website inside an actual mobile browser rendering engine on the device configuration you select, so what you see matches what your users see.
Each mobile browser uses a different rendering engine and handles CSS, touch events, and JavaScript differently from its desktop counterpart. Mobile Safari on iOS uses WebKit. Mobile Chrome on Android uses Blink. Both need explicit testing, and both behave differently from their desktop versions.
Access Safari on any iOS version directly from a Windows or Linux machine. No Apple hardware required, no local Xcode setup, no simulator downloads. Open a session and start testing in seconds.
Android fragmentation is real. Users run everything from Android 8 to Android 15 across hundreds of device models. TestMu AI gives you access to official Android emulators across all major versions, including Pixel, Samsung Galaxy, OnePlus, and more.
Your desktop layout passes every test. Your mobile layout is a different story.
Test across every mobile screen size and orientation without resizing your local browser window.
Many layout bugs only appear in landscape mode, or only when a user rotates their device mid-session. TestMu AI lets you switch orientation in any live session to catch exactly these failures.
Chrome DevTools device emulation approximates mobile rendering but uses your desktop browser engine. TestMu AI uses actual mobile browser rendering engines, which catch CSS behavior that desktop DevTools miss entirely.
From the compact 320px width of older iPhones to the wide viewports of modern Android tablets, TestMu AI covers the full spectrum of mobile screen sizes used by real users today.
Stop running mobile tests one device at a time.
No changes to your test logic, no new frameworks to learn. Point your tests at TestMu AI's cloud grid and run across every device configuration in parallel.
TestMu AI supports the most widely used mobile automation frameworks out of the box. Switching from a local emulator setup or another cloud provider requires updating one configuration file, not your test code.
HyperExecute distributes your mobile test suite across hundreds of emulator configurations simultaneously. A test run that takes hours sequentially completes in minutes, with full video recordings and logs for every session.
Native integrations with GitHub Actions, Jenkins, CircleCI, GitLab CI, Azure DevOps, and Bitbucket Pipelines. Mobile emulator tests run automatically on every code change before it merges.
Built for every mobile testing scenario that matters.
