MoviView — Responsive Design Tester

See your site on iPhone, Android, iPad and desktop in the same tab, with its real mobile version. Mockups and video with PRO.

Test your site on phone, tablet and desktop without leaving the tab. MoviView shows the page you're on inside realistic device frames, one device or several side by side. It's not just a narrower window: each device identifies itself as a phone, tablet or desktop, so sites with a separate mobile version show their real mobile version. FREE • Device mode in the same tab (click the icon or press Alt+Shift+V) • 9 popular phone, tablet and laptop models • Up to 3 devices at once, with synced scrolling and navigation • Phone + Tablet + Desktop in one click • True-to-scale frames with each model's real screen size • Free-form canvas: drag to pan, pinch to zoom • Portrait and landscape, with breakpoint labels for popular CSS frameworks • PNG screenshots of the complete devices on a white, gray or dark background, ready to share • Works on sites that block iframes, on localhost and on staging servers PRO • 140+ device models: phones, foldables, tablets and desktops • Record MP4 video of the devices, with visible taps • Annotate on top: arrows, pen, highlighter, boxes, text and numbered steps (they show up in screenshots and videos) • Page board: several pages of the same site on the same device, with movable screens, alignment guides and flow arrows • Mockup mode: layered devices for client presentations • Transparent-background PNGs, or any background color • 17 frame colors plus any custom color • Up to 6 devices at once, touch emulation and custom device sizes PRO pricing: US$5/month, US$39/year or US$79 lifetime. PRO turns on by itself a few seconds after checkout. 14-day money-back guarantee. Privacy: everything runs in your browser. MoviView doesn't store or send the pages you visit, and screenshots and videos download straight to your computer. Note: when you compare phone and desktop at the same time, Chrome shows the notice "MoviView started debugging this browser". That's what lets each device get its own version of the site, and it goes away when you leave device mode. The interface is available in English and Spanish.
