What is Responsive Web Design Tester?
'Responsive Web Design Tester' is an Edge extension that facilitates testing of your website's responsiveness. This tool simulates different device sizes and browsers, allowing previews of design visibility on various devices. It employs the correct User-Agent but doesn’t replicate device-specific web page rendering. Ideal for developers testing page adaptability, it supports both external and internal networks and allows custom device addition.

Quickly preview your websites design at the dimensions they will be seen on popular devices.

Add your own devices if you don´t find anything that suits your needs.
