BuiltWith is a new service that lets you search for a website, and it will tell you what’s going on behind the scenes.

For instance, you can search for a site and BuiltWith will pull up what language the site was built in, what services it uses for analytics and tracking, what server it goes through, which widgets are shown on the site, etc. It will also show data on the site’s advertising methods, aggregation functionality, document information and encoding. The basic analytics report you’ll find with BuiltWith is powered by Compete, but there are also links for you to gain additional information from sites like Alexa and Technorati.

The company has determined the different aspects of a website that it would get information for, so when you type in your search query, BuiltWith returns results that match up with the aspects it can profile. That being said, some information can fall through the cracks if you’re seeking out something that BuiltWith doesn’t look for, or if the site developer has inhibited a particular feature from being seen.

Another useful tool that BuiltWith offers is the percentage of other sites profiled in its database that use each metric that’s considered for this site profiling tool. It won’t indicate what sites these are, and there’s no directory of sites that it’s profiled (though there is a tag cloud for popular searches), so this tool is best used as a point of reference in regards to a particular site’s place in comparison with others BuiltWith has looked at. It would additionally be helpful for developers to search by the different aspects that BuiltWith gets information for.
