piwik is an open source web analytics software. It gives interesting reports on your website visitors, your popular pages, the search engines keywords they used … and so much more.

piwik is different from the competition because:

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. Piwik being 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, create the reports you want.

Embed your stats in your website!

You can very easily embed your graphs in your blog or website or dashboard:

You can try the online demo that shows you the latest piwik release. 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.
