NetTracker Lite was released as 'freeware' a couple of months ago. I needed a solution that would show me user experience data in particular. So I thought I would give it a try.
Most analysis tools are fiddly to set up, especially on Windows. But NetTracker Lite installed and ran first time, hooked up with my log files and gave me top class reports within minutes. The drill down reports are very impressive and the export options are useful.
The free version is limited to one website and one million page views, but that should do for most sites.
