Device detection can play an important part for advanced implementations of responsive design. These resources will help you get started without having to build your own device list. Device detection, however, is not something that should be looked at when building responsive sites. That isn’t to say that device detection does not have it’s placed in the responsive world, but as a general rule, you should be looking at feature detection rather than device detection. We have listed a series of device detection tools to help you out with your projects. They come in two flavours of client side and server side. There are also some external services that you can take advantage of including WURFL that takes the management of the ever-changing array of device types out of your hand.
