PHP Web Analytics script
CrazyStat is a web analytics script written in PHP. It does not need access to server-logfiles or a MySQL-database to generate realtime statistics of your website visitors. The script has very good usability and still has lots of features. The stats only need one screen length to present all the information. It's free and released under GPL as open source software.
The script can optionally also generate a graphical or textual counter so you do not need a second script for that.
