BuiltWith for Safari 1.1

BuiltWith is an efficient Safari extension for analyzing and displaying specific information about the website you are currently viewing.

BuiltWith’s goal is to help developers, researchers and designers find out what technologies pages are using which may help them to decide what technologies to implement themselves.
 
BuiltWith technology tracking includes widgets (snap preview), analytics (Google, Nielsen), frameworks (.NET, Java), publishing (WordPress, Blogger), advertising (DoubleClick, AdSense), CDNs (Amazon S3, Limelight), standards (XHTML,RSS), hosting software (Apache, IIS, CentOS, Debian).
