Mobile View is a free Chrome extension that overlays a real device frame on top of any live page, so you can see the desktop and mobile (or tablet) layout at the same time, in the same tab. Scrolling, clicks and typing stay in sync between the two views.
It's built for responsive web design work: preview a site across different phones and tablets without leaving the page, take clean device-framed screenshots for clients, portfolios or a GitHub README, and record the screen to show a layout in action.
Everything runs locally in the browser โ no servers, no analytics inside the extension, no tracking.

Web developers, front-end developers and designers who work with responsive layouts every day โ plus freelancers showing work to clients, and anyone building a portfolio or GitHub README that needs clean device-framed screenshots.
Most tools make you switch between desktop and mobile views. Mobile View shows both at the same time, in the same tab โ a real device frame sits on top of the live page, and scrolling, clicks and typing stay in sync between the desktop layout and the device preview. It's a lightweight browser extension rather than a separate app or paid cloud service, and everything runs locally with no tracking.
I'm a full-stack web developer, and I kept hitting the same friction: checking how a site looked on mobile while building the desktop version, and explaining responsive behaviour to clients over a call. Existing options either hid the desktop layout or felt clumsy, so I built the tool I wanted for myself โ and turned it into a free extension when other developers kept asking about it.
It's free, installs in one click, and works directly on any live page โ no separate app, account, or cloud service. You get desktop and mobile side by side with synced interaction, clean device-framed screenshots, and screen recording for client demos, all locally in your browser with no analytics or tracking.
MobileView.app appears to be a niche tool designed for previewing or testing how websites and apps render on mobile devices, offering a convenient way for developers and designers to check responsive design without needing multiple physical devices. Based on its apparent purpose, it can be a useful and good tool for quick mobile view testing, though it likely doesn't replace comprehensive testing platforms for professional-grade quality assurance.
