Online Mobile Browser Testing

Browserling offers free online cross-browser testing on mobile devices. That means you can open your website in real mobile browsers without buying a pile of phones and switching cables. We run the mobile devices and give you quick remote access to the browser on each device.

On the devices, we have installed the most popular browsers, such as Chrome, Firefox, Safari, Opera, as well as lesser known Brave browser, Duck Duck Go browser, Orion browser, and Vivaldi browser. Each mobile browser also has multiple versions available, so you can test both older and the latest releases.

Online Mobile Browser Testing Use Cases

Mobile browsers behave differently from desktop browsers in almost every aspect: layout, input, performance, networking, and APIs. Browserling provides access to real mobile browsers so developers can test and debug these differences in mobile environments.

  • Cross-browser testing on mobile. Mobile browsers use different rendering engines. Chrome and Opera on Android use Blink, Firefox uses Gecko, and all iOS browsers use WebKit. Browserling lets you test the same site across various engines to catch CSS, JavaScript, and rendering differences.
  • Native Safari and WebKit debugging. Many bugs only occur in WebKit-based browsers. Since all iOS browsers are WebKit-based, testing in native Safari is required to reproduce layout issues, CSS glitches, and scrolling bugs that do not appear on desktop browsers.
  • Android version and device fragmentation. Android devices vary by OS version, screen size, and screen pixel density. Browserling makes it possible to test across different Android versions and browsers to identify issues related to viewport handling, font scaling, media queries, and UI rendering.
  • Touch and gesture handling. Mobile browsers introduce input models that do not exist on desktops. Browserling allows testing of touch events such as taps, scrolling inertia, and pinch-to-zoom to verify correct event handling and UI responsiveness.
  • Mobile-specific JavaScript APIs. Browserling enables testing of APIs that are primarily used on mobile, such as touch events, orientation changes, viewport resize events, and media queries tied to device characteristics.
  • Responsive layout testing on real devices. Desktop browser emulation does not fully reproduce mobile behavior. Browserling runs sites inside real mobile browsers, allowing developers to test viewport units, CSS media queries, safe areas, dynamic toolbars, and mobile-specific layout constraints.
  • Mobile network behavior. If you enable the geo-browsing feature that routes traffic via mobile IPs (4G/LTE networks), mobile browsers will operate slower will have less reliable network conditions. Testing such scenario helps expose issues related to content loading strategies, lazy loading, client-side caching, and race conditions that do not show up on fast desktop connections.
  • Regression testing across mobile browser versions. Browserling provides access to multiple browser versions, allowing developers to reproduce old bugs, confirm fixes, and verify behavior changes between mobile browser releases.
  • Debugging mobile-only bugs. Some issues only occur on phones and tablets and cannot be reproduced on desktops. Browserling provides a reliable way to reproduce, inspect, and debug these issues in real mobile browsers.
  • Security testing of mobile-targeted links. Some phishing links and suspicious downloads are designed to trigger only on mobile browsers. Browserling is used to safely open and analyze mobile-only attack flows, such as deceptive permission dialogs, redirect chains, and other behaviors that do not activate on desktop browsers.

Online Mobile Testing FAQ

Can I use mobile browsers online without owning a phone?

Yes! Browserling gives you live access to real mobile devices through your browser. You don't need to own a phone, install apps, or download SDKs. Everything runs in the cloud.

Which mobile operating systems do you support?

We support Android and iOS. Multiple versions of each operating system are available so you can test how your website behaves on both new and older devices.

Why is mobile browser testing important?

As of 2026, over 60% of global web traffic now comes from mobile devices. Mobile browsers differ significantly from desktop browsers in layout, font rendering, touch events, viewport handling, and performance. Testing on real mobile devices ensures your site works exactly as users expect.

Can I test my website on mobile from a desktop computer?

Absolutely. You can use Browserling on macOS, Windows, or Linux to remotely access mobile browsers. For example, you can instantly open Chrome on Android using this link: browserling.com/browse/android/chrome.

How do I check responsive layouts on mobile devices?

With Browserling, your site runs in an actual mobile browser, not a resized desktop window. This lets you verify real viewport behavior, CSS media queries, mobile fonts, and scrolling exactly as they appear on phones and tablets.

Can I test different screen sizes and orientations?

Yes! You can rotate devices between portrait and landscape modes and test various screen sizes, including phones and tablets. This makes it easy to ensure your layout adapts correctly across devices.

Is mobile testing different from responsive testing in DevTools?

Yes. Browser developer tools simulate mobile viewports but still run desktop browser engines. Mobile testing in Browserling uses real mobile browsers, real touch input, and real mobile rendering engines.

Which mobile browsers use WebKit?

On iOS, all browsers use Apple's WebKit engine due to platform restrictions. This includes Safari and third-party browsers. On Android, browsers may use Blink (Chrome-based) or Gecko (Firefox).

What is the latest Android version?

Androids are regularly updated by Google and the latest Android version is 16. Browserling runs all Android versions starting from 4.4 and makes them available for testing.

What is the latest iOS version?

The latest iOS version is 26 and it's released annually by Apple and receives frequent updates.

Can I test touch events like swipes?

Yes. Since we use real mobile devices, you can test taps, scrolling, and zooming exactly as users experience them.

Do mobile browsers handle cookies differently?

Cookies behave similarly across platforms, so mobile browsers have pretty much the same rules as desktop browsers. Testing on real mobile browsers helps uncover any differences.

Can I test mobile apps in Browserling?

Yes. Browserling focuses on mobile web testing and also app testing. Coming soon, you'll be able to just drag and drop an app into a mobile Browserling device and run it on the selected mobile phone.

What is the difference between a mobile emulator and a real device?

A mobile emulator imitates a device in software, often missing performance characteristics, GPU behavior, and touch accuracy. Real devices provide authentic rendering, input handling, and performance.
