What is Screenfly?

Screenfly allows you to view your website on a variety of device screens and resolutions. Enter a URL and click on GO to get started.

Concerning pixel density

On devices with densely pixelated screens, websites are often rendered using reference pixels instead of the traditional hardware pixel. This means that even though your high-definition tablet may have a 1200x800 screen resolution, websites may be rendered as if they were displayed on a screen half that size. Keep in mind that resolutions in Screenfly refer to the rendered resolution, and not necessarily the native resolution of the device you’re testing.

About the proxy server

Screenfly can use a proxy server to mimic devices while you view your website. The proxy server mimics the user agent string of the devices you select, but not the behavior of those devices. For example, most mobile phones and tablets have a zoom feature that displays the entire page at once, even if it appears to be clipped off the edges of the screen here.

Having trouble?

Screenfly doesn’t work on every website. Some websites don’t like to be displayed inside of frames, and others won’t work with the proxy server. For best results, be sure to use the latest version of a modern web browser, such as Firefox, Safari, or Chrome. If you continue to have problems, feel free to get in touch and let us know.
