Throttle network speed on real devices to simulate 3G, 4G, 5G, or offline conditions across live and automated sessions.
Get accurate results for motion-sensitive features and orientation-based UI using real accelerometer, gyroscope, and barometer sensors.
Run extended streaming sessions, on real iOS and Android hardware to validate video quality, syncing, layout, buffer time, and more, all from your browser.
Check accessibility testing on real iOS and Android devices including dynamic text sizing, high-contrast mode, colour inversion, reduced motion, display zoom, and assistive touch.
Locate elements, debug layouts, verify accessibility, and inspect app state directly on real iOS and Android hardware with built-in Appium Inspector and native DevTools.
Set a device's location to any country to test for localized pricing or currency display, regional push notifications or offers, and beyond.
Supports image capture testing, QR code scanning verification, and barcode scanning assessment
Test on Real Devices Your Users Actually Carry
17 Pro, 17, 16 Pro Max, 16 Pro, 16, and more
Flagship S-series through the latest release, plus foldables
Current and recent generations
New flagships land on day zero. The Galaxy Z Fold8, Z Fold8 Ultra, Google Pixel 11 Pro, and Pro XL are live on TestMu AI's real device cloud before reaching a single store.
TestMu AI Real Device Cloud Covers Every Real Scenario
Test your mobile app and website on every device your users own. From parallel testing, running no-code tests to debugging within the session, we have got you covered.
REAL DEVICE CLOUD
Test, scale, and debug on real devices
Run live and automated app tests on the exact device, OS, locale, and carrier your users actually use.
Test on a real device free
Tap, swipe, pinch, zoom, rotate, and multi-touch capabilities, tested exactly as your users perform them. Every interaction runs on real hardware your users actually hold.
Distribute your suite across real device and OS combinations in parallel across multiple devices. Same tests, same pipeline, faster results.
Identify crashes, trace network requests, and inspect layouts without leaving the dashboard or losing your session context.
KANE AI
The AI-native way to run tests
KaneAI is the no-script alternative to legacy codeless test automation tools. You write the intent, and KaneAI does the construction.
Learn more about KaneAINo Appium, no scripting knowledge required. Describe your test scenario like "Test Face ID login on iPhone 17 under 4G throttle" and KaneAI converts it into a running automated test on a real device.
When a UI element changes - a button renamed, a field repositioned; KaneAI automatically updates the locator and keeps the test running.
Every test KaneAI writes, runs on real iOS and Android hardware. Face ID, camera, GPS, and network throttling all behave exactly as they do in your users' hands.
Automate Browser Flows from your
Terminal with Kane CLI
Plug into TestMu AI's Real Device Cloud
Point your Appium, XCUITest, Espresso, Detox, or Maestro suite at our cloud with one endpoint change. No rewrites, no migration.
