Need to see website on mobile widths without picking up a phone or leaving the tab? Mobile View extension turns the browser to mobile view on the live page, so you can compare widths in a second and keep working. 🧭 Getting started takes seconds 1. Pin the extension to your browser toolbar 2. Open any site and click the icon 3. Pick a device or type a custom size 4. Add a second screen and check your site on mobile side by side Here are 5️⃣ reasons to give this mobile view switcher a try: 1️⃣ It works as a phone simulator on the live page, with no second window 2️⃣ Several screens sit side by side, so one glance covers every breakpoint 3️⃣ Your session stays alive, so logins and carts keep working in mobile view of website 4️⃣ A built-in inspector shows the CSS of any element you point at 5️⃣ The pages you preview render locally and are never uploaded anywhere 📱 What you can do with the mobile viewer ➤ Designers see website in mobile view and compare two widths before the handoff. ➤ Developers catch layout bugs in the same browser tab they already work in. ➤ QA engineers test site from other devices without a drawer of phones and catch broken grids early. ➤ Marketers check a landing page at phone width before a campaign goes live, not after complaints. ➤ Support teams reproduce a complaint at the width the customer reported, without leaving the ticket. 🔬 How the engine works The site opens in the same tab and the same origin, so cookies stay first-party. That is why logins and OAuth survive. The mobile website viewer shows the real thing, not a copy. A phone user agent goes out with the request, so the server returns exactly what a handset would get. 📌 Popular Mobile View chrome use cases - A landing page check before an ad campaign - A mobile page test after a CSS refactor - A quick look at a client site during a call - A pass over a long form on a narrow screen 👥 Who benefits from the website Mobile View ▸ Freelancers show a client the mobile view of website during a call ▸ Agencies keep several sizes open and compare them at once ▸ Students learn responsive layout by watching it change live ▸ Shop owners check a product card at phone width before it goes public Any mobile simulator - responsive testing tool is only useful when it tells the truth, so the preview reports a phone user agent, phone screen metrics and the touch signals a page checks for. Breakpoints and media queries behave as they do on a handset, not in a narrow window. Every screen stays in step with the others. Scroll one and the rest follow by the same share. Click a menu in one and the same control opens everywhere, so you never repeat the same tap four times while you test your site on mobile widths. As a mobile simulator extension, it stays in the tab you already have open: no second app, no device farm, no cable. The preview refreshes with the page, so a save and a reload show the change. 🧪 How to get more out of the mobile site viewer 🟡 Start with the two sizes your analytics show most, then add the odd ones 🟡 Keep one narrow screen open to view on mobile while you edit 🟡 Turn frames off when you need raw viewports and more room to work 🟡 Rotate a screen to landscape to check tables and wide media 🟡 Save your own size when a client asks about a device not in the list 🛡 Speed, privacy and convenience • A website previewer that opens instantly in the active tab and never slows the site down • No signup to get started.
