How to Check If Your Website is Responsive on Mobile Devices

Focus on iOS and Android. You need iOS or macOS since Safari can only be tested on Apple devices. On Android, you can test all essential Chromium browsers (Chrome, Edge, Samsung Internet, Opera—they’re basically the same). The only outlier is Firefox. For browser usage insights, check my Instagram post: Top 10 Web Browsers Right Now. Also, test all key screen resolutions, including tablets in both landscape and portrait.

1. Place is Amazon AWS Device Farm (klick here)

In my experience, the best way to test your website across all major devices (Samsung, Apple, Google) and essential browsers (Chrome and Safari) is by using Amazon AWS Device Farm. Simply set up an AWS account, and you’re ready to go.

  • No monthly subsciption
  • Pay as you use (0.17 cent per minute)
  • Choose Phones or Tablets
  • IOS and Android (Chrome and Safari)
  • Real Devices

2. Place is Browerstack (klick here)

Before discovering AWS Device Farm, I used BrowserStack. It offers a similar experience but comes with a few extra features.

  • Monthly subscription only
  • Choose Phones, Tablets and Desktops
  • IOS, Android, Windows and Mac
  • Safari, Chrome, Edge and Firefox
  • Real Devices

3. Place is Chrome Developer Tools (start here)

It simply simulates devices and their resolutions, but it’s a great starting point—I always begin here since I develop with Chrome anyway.

  • Free
  • Set up your own devices
  • Always start here

What I currently use as devices is:

Smartphones: Samsung S25 360x780px, Pixel 8 412x915px, Iphone 16 393x853px

Tablets: Google Pixel 1280x800px, Galaxy S10 1480x924px, Ipad Pro M4 1376x1032px

4.  Android Studio IDE (klick here)

Android’s Developer Studio (similar to Visual Studio Code) includes a feature called ‘Virtual Device Manager,’ which lets you emulate Android phones. It works reasonably well, though I’ve experienced some occasional freezes while using it.

  • Free
  • Only Android
  • Only Pixel Devices
  • Choose Phones, Tablets and Desktop
  • Emulator only

5. Set up a virtual box VM

If you, like me, use a Windows + Android setup, you can always set up a virtual machine with macOS to test your site on Safari.

6. Buy Real Devices

Finally, there’s always the option to buy real devices—one iOS and one Android phone, plus maybe a tablet. Testing on actual hardware is always the most reliable way to see how your site performs.

What it don’t use: Responsive Checker Websites

As an alternative to AWS Device Farm and BrowserStack, you can also try LambdaTest.
