What is that site built with?

Built With  www.builtwith.com

This is a great web app for showing what technologies are going into sites. When I run across a site that I think has a nice feature or are wondering what type of technology is under the hood, I run it through Built With. I like seeing what CMS or Ecommerce technology a site is using.

Aside from helping to see what technologies are powering a site, they have a lot of statistical data around site technologies. Do you want to know what the most used blog software is? Or the javascript library running on sites? This allows you to see that. Now, just something to keep in mind, I am pretty sure that they only have data from sites that have actually been run through Built With. So the numbers in their statistics don’t represent the entire inter web. I hope to see the usage of this site increase to be a better representation in the future though
