Top 15 Responsive Web Design Testing Tools

         Responsive Web Design, also known as adaptive web design (often abbreviated as RWD), enables websites to be read and navigated across a wide range of browsing devices—from desktop computer monitors to mobile phones or other mobile products—while minimizing the need for zooming, panning, and scrolling. In other words, a responsive website can automatically respond to end-user behavior. When new devices hit the market, there’s no need to spend additional time designing and developing for them.

Responsive design aims to provide the optimal visual experience for each website on different devices. So how can you tell whether a website adjusts automatically based on the device? That requires designers to test the site’s responsiveness. This article introduces 15 of the best responsive website testing tools. They can help you check whether your site’s design responds gracefully to various devices, and assist you in designing websites that adapt to devices of different sizes and operating systems.
