TinyAnalytics

After having tested many open-source website analytics tool, and haven't found exactly what I was looking for, I started a minimalist project (coded in PHP) that only does this:

• number of visits per day

• display the referrers (i.e. the people who have a link to your website)

If you're looking for a tool lighter than Piwik, Open Web Analytics or Google Analytics, then TinyAnalytics might be what you're looking for.
