Piwik is a downloadable, open source (GPL licensed) web analytics software program. It provides you with detailed real time reports on your website visitors: the search engines and keywords they used, the language they speak, your popular pages… and so much more.
Piwik aims to be an open source alternative to Google Analytics.
What makes Piwik unique from the competition:
- Piwik’s 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 web analytics plugins!
- 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)
- 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!
- Real time web analytics reports: in Piwik, by default reports are generated in real time. For high traffic websites, you can choose the frequency for reports to be processed (more info)
