Responsive Viewer
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.

MobileView.appThis service is highly recommended for software development teams, QA engineers, and web developers who need to ensure compatibility and functionality of their web applications across multiple browsers and devices. It is particularly useful for organizations with a focus on maintaining high-quality user experiences across various platforms.
MobileView.app's answer:
It's a Chrome extension (Manifest V3) built with vanilla JavaScript, HTML and CSS using the Chrome extension APIs. Screen recording uses the browser's native capture and WebCodecs APIs. The website is a static site.
MobileView.app's answer:
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.
MobileView.app's answer:
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.
MobileView.app's answer:
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.
MobileView.app's answer:
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.

Yeah I moved on pretty quick from browserstack, but it seems to be the most popular. I've tried crossbrowsertesting.com but at the moment I really like app.lambdatest.com. Source: almost 4 years ago

Fortunately we donโt need to install, nor configure, any other tools, unless maybe some fancy reporters, but for now we can get everything we need in terms of end-to-end automated testing out of Nightwatch. Besides Chrome, Nightwatch has built-in support for all major browsers, including Firefox, Edge, and Safari, all thanks to its integration with the W3C Webdriver API and Selenium.

Professionally, I do basically the same for dev testing. We also have various devices on different platforms/versions in the office when needed, and our QA team primarily uses Cross Browser Testing Tool. If I need to check something specific, I usually use CBT. Source: over 5 years ago
