Piwik is a downloadable, open source (GPL licensed) web analytics software program. It provides you with detailed 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.
Piwik is a PHP MySQL software program that you download and install on your own webserver. At the end of the five minute installation process you will be given a JavaScript tag. Simply copy and paste this tag on websites you wish to track (or use an existing plugin to do it automatically for you).

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 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)
- (NOW AVAILABLE!!!) 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
- you can try the online demo that shows you the latest Piwik release. Please note that Piwik is a constant work in progress and some user interface parts are being updated as we speak!
- 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.
Embed your stats in your website!
You can very easily embed your graphs in your blog or website or dashboard:
- Last 30 days visits
- Browsers families - bar chart
- Countries - pie chart
Want to know more?
Piwik is under development and the core team is growing. We have big plans for Piwik and we are happy you want to know more! We often post news on the official blog (subscribe to the rss feed).
If you want to help and make piwik better, you are welcome. You can, for example, tell us by email if you want to work on translations or beta-testing.
If you are a developer, you can definitely help. One of our main mid term objective is to make it easy for external developers to build plugins for Piwik. Help is also welcome if you want to work on the core of Piwik: there are lots of interesting problems to solve, new features to implement and bugs to fix.
The developer zone contains all the resources to get started. The roadmap will tell you where we are going to. You can report a bug or work on some of the existing bug reports. For any technical questions you should ask on the piwik-hackers mailing list ; we will be happy to help.
Thanks OpenX!
Piwik has been made possible thanks to OpenX, the open source adserver!
