Piwik is a PHP MySQL software program that you download and install on your own webserver. At the end of the five minute installation process you will be given a javascript tag. Simply copy and paste this tag on websites you wish to track (or use an existing plugin to do it automatically for you) and access your analytics reports in real time.
