I'm a solo developer, and I built Mobile View to scratch my own itch: I was constantly toggling DevTools (or opening a separate responsive tab) just to check how a site looks on mobile vs desktop.
Mobile View overlays a real phone or tablet frame right on top of any live website, so you see the desktop and mobile layouts at the same time — no DevTools, no separate device. Scrolling, clicks and typing stay in sync across both. Switch devices, rotate, set custom sizes and zoom, change theme and language. Take screenshots or record the screen (WebM), use focus mode, and more. Works on any responsive site. Free, no account, runs fully locally in your browser.
