Plecost is a WordPress fingerprinting tool. The main use is to help discover if a webpage is running WordPress and if so which version. It also can detect what plug-ins are installed with their version number.
Warning: It appears at this time that is has been awhile since it has last been updated so while the plugin list is outdated it still reports back the version number of all detected plugins which can be looked up by hand.
