Device Simulator – Mobile & Responsive Tester

Description

See how any web page looks on phone, tablet and laptop screens with real size, user agent and touch. Compare devices side by side. Device Simulator lets you see how a web page looks and behaves on a phone, tablet or laptop without leaving Chrome. Each preview uses the real screen size, pixel density and touch input of the device you pick. It is made for web developers, designers, QA testers and online sellers who want to check their page the way a customer sees it. WHAT YOU CAN DO • Preview a page in a device frame and switch devices from a list of dozens of presets • Use Responsive mode: drag the frame edge or click a breakpoint, with Tailwind labels • Add your own device with a custom size, pixel density and user agent • Rotate the device, zoom, and scroll by dragging like on a touch screen • See the on-screen keyboard appear when you tap a text field, to check that forms are not covered • Highlight elements that cause horizontal overflow, with the overflow size in pixels • Scan a QR code to open the same page on a real phone on your Wi-Fi • Take a screenshot or export a mockup image with a transparent, gradient or custom background PRO FEATURES • Compare several devices side by side with synced navigation and scrolling • Compare two addresses (A/B), for example a test version and the live site • Mirror clicks and typing across frames, and inspect elements in every frame • Deep emulation: touch-like hover and pointer behavior, light and dark scheme, slow or offline network • Record the device screen as a video, capture the full page, and export high-resolution mockups FREE AND PRO Everything not listed under Pro is free, with no account needed. The free plan includes phones up to iPhone 15; the newest iPhones are part of Pro. Pro is sold monthly, yearly or lifetime, with one key per device. Plans and prices are shown in the extension under "License & Pro upgrade"; payment is by PayPal (USD) or bank transfer in VND, and your key activates automatically when the payment arrives. LANGUAGES The interface is available in English, Spanish, French, German, Portuguese and Vietnamese. Choose one from the toolbar; by default it follows your browser language. PRIVACY The extension does not read or send page content or browsing history, and has no ads or analytics. It only contacts the license server to fetch announcements, validate a Pro key (key, random device ID, a label such as "Chrome · Windows", and the version number) and process a Pro purchase (selected plan, contact details only if you enter them, browser type, language, time zone).
