How do I test a website on mobile devices?

Enter your URL in a TestMu AI session and the page opens in a real mobile browser on a real phone. You can scroll, tap, and inspect the page with on-device developer tools, then run the same checks automatically across more devices.

Can I test my website on mobile browsers for free?

Yes. The free plan includes 60 minutes of real device and browser testing and needs no credit card. Sign up, enter a URL, and start a session.

Which mobile browsers can I test on?

Chrome on Android, Safari on iOS, plus Firefox and Edge, running on real devices across current and older OS versions.

Is this an emulator or a real device?

A real device. Emulators approximate a phone on your computer and miss real hardware, memory, and network behaviour. TestMu AI runs your site on 10,000+ real Android and iOS devices.

Can I test a staging or localhost site on a mobile device?

Yes. A secure tunnel exposes a locally hosted or firewalled environment to the device, so you can test before anything is public.

How do I test my website on Chrome on a phone?

Pick an Android device, launch Chrome, and enter your URL. Chrome DevTools attaches to the live session, so you can inspect the DOM, watch network requests, and debug JavaScript on the real browser.

Can I use Chrome DevTools on a real mobile device?

Yes. Full Chrome DevTools access is available during mobile Chrome sessions for DOM inspection, network monitoring, JavaScript debugging, and render profiling.

How do I check my site at different mobile screen sizes?

Open the same URL across device generations and screen sizes to validate breakpoint behaviour, CSS grid and flex layout, font scaling, and tap target sizing on real form factors.

What is the difference between mobile web and mobile app testing?

Mobile web testing checks a site in a mobile browser: layout, breakpoints, touch targets, and browser differences. Mobile app testing checks an installed native or hybrid build. For APK and IPA testing use the real device cloud.

Can I automate mobile web tests with Selenium or Playwright?

Yes. Point your Selenium, Playwright, or Cypress suite at TestMu AI with one endpoint change and run mobile web tests in parallel.

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.
