Responsive Testing
Verify your website looks perfect on every screen size. Test layouts across mobile, tablet, and desktop resolutions using real browsers in the cloud.
Start Responsive TestingWhy Responsive Testing Matters
Over 60% of web traffic comes from mobile devices. If your website doesn't adapt to different screen sizes, you're losing visitors and revenue. Responsive testing catches layout issues before your users do — broken menus, overlapping elements, unreadable text, and hidden call-to-action buttons.
Browser DevTools can simulate different viewports, but they don't replicate real rendering behavior. MyBrowser runs actual Chrome and Firefox instances at real resolutions, giving you pixel-accurate results that match what your users see.
