Piwik is a downloadable, open source (GPL licensed) web analytics software package. It provides detailed reports on your website and its visitors, including the search engines and keywords they used, the language they speak, which pages they like, the files they download and so much more. Piwik aims to be an open source alternative to Google Analytics.

Piwik is the leading open source web analytics software. However, there are dozens of other free and paid web analytics solutions; why choose Piwik?

One of the principle advantages of Piwik is that you are in control. Unlike remote-hosted services (like Google Analytics), you host Piwik on your own server. The installation process is very simple, and Piwik is just as simple to use and understand.

All the program's features are built as plugins, which means you can easily add new plugins built by the community to customize your own Piwik installation. If you have specific needs then you can build a plugin that processes data in a different way.

Piwik is installed on your server, which gives you full control over your data. You can access the data easily via the Piwik API. Advanced users can also run manual queries on the database in order to build advanced reports.

Because you own your data, you don't make it available to third-party companies which might reuse this data for other purposes.
