GoAccess is an open source real-time web log analyzer and interactive viewer that runs in a terminal in *nix systems or through your browser.
It provides fast and valuable HTTP statistics for system administrators that require a visual server report on the fly.
A free web analytics script written in PHP. It does neither need access to your server's logfiles nor a MySQL-database to generate live statistics of your visitors. It's fast because of its caching technology and uses minimal webspace by compressing its logfiles. The script is very easy to use and very flexible.
It's not only a Web Analytics script such as Google analytics, AWstats, phpMyVisites or Piwik, but it's a complete tool. With CrawlTrack you will get informations that all the others are unable to give.
