About Responsive Design Checker

Responsive Design Checker loads a website at a range of mobile, tablet and desktop screen sizes, so you can see how the layout adapts without switching devices. It runs in the browser and needs no installation.

The site also explains what responsive design is and how to approach it. To prevent misuse, requests are throttled to five in a five-minute period. It suits designers and site owners who want a quick visual check.
