MobiView Simulator – Responsive Device Preview

Preview any website on Apple, Samsung, Dell, HP and Zebra phones, tablets, laptops, desktops, TVs and watches side by side.

MobiView Simulator opens the page you're on in a clean workspace and shows it on a desktop, tablet, phone and watch side by side, each in a realistic device frame at its true screen size. Choose from 99 built-in screen sizes covering current phones, foldables, tablets, laptops, desktop monitors, TVs, smartwatches and rugged handhelds from the major manufacturers. Pick them from a searchable list inside the app, or add your own custom sizes. • Add your own custom sizes REALISTIC FRAMES Dynamic Island, notches and punch-hole cameras, foldable creases, MacBook notch, monitor stands, watch crowns and bands — with status and navigation bars drawn outside the page so every viewport size stays exact. Desktop scrollbars are hidden inside phones, just like the real thing.

PRIVATE BY DESIGN No account, no analytics, no tracking, no remote code. Site access is requested only when a site needs it, and only for that site.
