See exactly how any website looks on every device, straight from your iPhone or iPad. ViewPortal loads any URL in a real browser engine and renders it at true device sizes, so what you see is what your visitors get. No scaled-down screenshot, no guesswork. Type a URL. Pick a device. Done. TRUE-TO-DEVICE VIEWPORTS - Pages render at each device's exact width, so layouts wrap, break and reflow just like they do in real life. - The layout viewport is forced to the real width, so media queries and breakpoints fire correctly. - Live pixel-size readouts show the precise dimensions you are testing. EVERY DEVICE, ONE TAP AWAY - iPhone: SE, 17e, 17, 17 Pro, 17 Pro Max. - iPad: mini, iPad, Pro 11", Pro 13". - Mac: MacBook Neo, Air 13", Air 15", Pro 14", Pro 16", iMac 24". - Faux device chrome — notch, Dynamic Island and status bar — drawn in for realistic framing. - Flip any device between portrait and landscape. SIDE-BY-SIDE MULTI-VIEW - On iPad in landscape, place phone, tablet and desktop next to each other. - Every pane loads the same URL; configure each one independently. - Focus or go fullscreen on any pane for a closer look. PINCH, ZOOM, EXPLORE - Crisp pinch-to-zoom, exactly like a real browser. - Inspect the smallest details, then step back to see the whole layout. PREVIEW YOUR LOCAL WORK - Point ViewPortal at localhost or a LAN dev server (such as 192.168.x.x). - Check work in progress and catch breakpoint bugs before you ship. - Favourites and recents keep the sites you test most a tap away. PRIVATE BY DESIGN - No accounts. No analytics. No tracking. - URLs, favourites and preferences stay on your device and are never transmitted. A clean, monochrome, ink-on-paper interface keeps the focus on your work. Responsive design testing, wherever you are.
