Hey everyone,

While working on one of my projects, I kept running into the same problem: checking the UI across different screen sizes was taking more time than the actual change sometimes.

I’d fix something on desktop, then notice it looked off on mobile. After fixing mobile, tablet would need changes too. Most of the time I was just resizing the browser, switching device modes, and trying to remember what broke where.

I looked for tools that could make this easier, but most of them didn’t really fit how I wanted to review things. So I built a small Chrome extension called Multi Device Viewer.

It lets you preview multiple screen sizes side by side in one place, so you can catch responsive issues faster.

A few things it helps with:

• Viewing multiple devices at once
• Testing mobile, tablet, desktop, and custom screen sizes
• Spotting layout issues across breakpoints
• Reviewing UI changes without constantly resizing or switching tabs

I’m still improving it, so I’d really appreciate any feedback, ideas, or bug reports if you try it.

Hey everyone,

While working on one of my projects, I kept running into the same issue again and again: checking responsiveness across multiple devices was taking way too much time.

I would make a small UI change, it would look fine on desktop, but then something would break on mobile. Then I’d fix mobile, and tablet would look off. It became a loop of resizing the browser, switching device modes, and testing one screen size at a time.

I tried looking for tools that could make this easier, but most of them either showed only one device at a time or didn’t really fit how I wanted to review the UI.

So I built Multi Device Viewer, a Chrome extension that lets you preview multiple devices side by side in one view.

It helps with:

• Viewing multiple devices at once
• Testing mobile, tablet, desktop, and custom screen sizes
• Catching responsive layout issues faster
• Reviewing UI changes without constantly resizing or switching tabs

Would love to hear your feedback if you try it.https://chromewebstore.google.com/detail/multi-device-viewer/jfcnekmenjickfihkniaoaklehjmdhdb?authuser=0&hl=en-GB
