Piwik is a  open source web analytics software, providing you with detailed reports on your website visitors: the search engines, keywords, language, your popular pages and much more.

What makes Piwik unique from the competition:

1. the features are built inside plugins: you can add new features and remove the ones you don’t need. If you are a developer, you can easily build your own plugins!
2. you own your data: because Piwik is installed on your server, the data is stored in your own database and you can get all the statistics using open APIs (publishing the data in many formats: xml, json, php, csv)
3. the user interface is fully customizable: you can drag and drop the widgets you want to display and create a report especially tailored to you!

Give it a try

• to install Piwik, download the latest release, upload it on your webserver (you need at least PHP 5.1 and a Mysql database), and open your browser: the installation process is automatic and takes less than 5 minutes.
