View your website on multiple devices and check out how responsive your website is! Enter in your website URL below, and choose different devices and screen resolutions to display your website accordingly below. If you are using Ultimate Web Builder software (Promo, PromoU, Essentials+, Lite, and Full from version 3.4+) and have the responsive feature ON, you can view the automatic page reformatting in action here! Ultimate Web Builder software calculates responsive design based on screen resolution, so you can check out the responsive action for a smartphone on your laptop, for example, or even by going to your website and resizing your browser window.

*Note: This does not simulate exactly the user experience on a specific device - for the exact experience, you should check on that specific device. But this does make an excelling testing environment!
