Some of the ASF websites use Matomo to understand what parts of the website are important to our users, what features are most frequently read up on, where users get lost in the documentation, etc. This data allows us to better understand how users use the system, the website, and the docs and where to focus improvements next.

You can look at Matomo here:

If you need to learn more about your users, you can ask for a site ID and tracking code at and join projects such as Apache Flink, Apache Shiro and Apache Maven. We enforce cookieless measurements.

A basis tracking code for Matomo looks like this (where <YourSiteId> is replaced by the provided site ID):

    <!-- Matomo -->
      var _paq = window._paq = window._paq || [];
      /* tracker methods like "setCustomDimension" should be called before "trackPageView" */
      /* We explicitly disable cookie tracking to avoid privacy issues */
      /* Measure a visit to and as the same visit */
      _paq.push(["setDomains", ["*","*"]]);
      (function() {
        var u="//";
        _paq.push(['setTrackerUrl', u+'matomo.php']);
        _paq.push(['setSiteId', '<YourSiteId>']);
        var d=document, g=d.createElement('script'), s=d.getElementsByTagName('script')[0];
        g.async=true; g.src=u+'matomo.js'; s.parentNode.insertBefore(g,s);
    <!-- End Matomo Code -->
