Piwik is a downloadable, Free (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 downloadâ€¦ and so much more.
Piwik aims to be an open source alternative to Google Analytics.
To learn more about what Piwik offers, check out the list of features page.
Piwik is the leading open source web analytics software, but 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 (such as Google Analytics), you host Piwik on your own server and the data is tracked inside your Mysql database. Because Piwik is installed on your server, you enjoy full control over your data. You can access the data easily via the Piwik APIs. Advanced users can use Custom Variables, Segmentation, or even run manual queries on the database in order to build advanced reports.
Piwik also protects your visitor privacy with advanced Privacy features. When using Piwik for Web Analytics, you ensure that your visitors behavior on your website(s) is not shared with advertising companies.
If you are using Google Analytics and starting to use Piwik, you can import your Google Analytics data history into Piwik. You can also use several web analytics tools at the same time so feel free to experiment!
To help you decide on a Web Analytics software, you might want to look at the list of features in Piwik or the online demo. Piwik offers nearly all features that other tools may offer, and also has some unique features such as Real Time visitor details, Ecommerce Analytics, and an awesome Mobile App.
In Piwik, you can create an infinite number of users and websites to track.
For each user, you can set permissions to "view", "admin" or "no permission" for a specific website, or for all websites at once.
The permission system in Piwik is simple and makes it very easy to manage from a small number of websites and users to hundreds of websites and thousands of users. See the Manage Users documentation.
You can add unlimited websites to track in Piwik, in the Admin Websites section. In fact, Piwik scales well to thousands of websites, and a few Piwik users are tracking even more. Each Website is defined by a URL. You can track sub domains in the same Piwik website, or you can create a different website for some of your subdomains. Learn more about creating Websites in the Managing websites page.
If you track many subdomains in the same Piwik website, you might want to have the domain name appear on your Page Title reports: "support.example.org/Homepage" rather than "Homepage", check out the JS setDocumentTitle documentation.
In the Admin Websites page, you can also define for each website a list of Alias URLs which contains all the other domains and subdomains that will be tracked. This will ensure they don't appear in your "Referer" reports.
If you track more than 10 websites, the Website selector will display the first ten sites only, and show a search field where you can search quickly to look at another website. Check out the 'All Websites' dashboard as well, a very useful first page to look at for a quick overview of the performance yesterday or last week or all your sites. You can even make it your defaut page to load in Piwik in your user settings.

The official Piwik Mobile App supports all these reports, including the 'All Websites' dashboard.
You can add unlimited number of Goals to track in Piwik (newsletter subscription, file download, 'thank you' page, etc.). Learn more about how to track your website Goals in the Goal Tracking documentation.
By default Piwik uses the browser language to determine location. To improve accuracy of country detection (and enable Region and City tracking), go to Piwik > Settings > Geo Location. Then, you can select the appropriate solution for your install. These include GEOIP database from Maxmind (for shared hosting) or a server side solutions such as GeoIP Apache or GeoIP PECL modules. Learn more about Visitors geo location in Piwik.
Piwik provides advanced Ecommerce Tracking and Reporting functionnality. Learn more in the page Ecommerce Analytics.
Piwik is the ideal Web Analytics software that respects Privacy, thanks to its Free/Libre software nature and useful Privacy settings, setting it apart from other commercial tools such as Google analytics. To ensure and respect your visitors Privacy, you can:
1) automatically anonymize Visitors IPs,
2) include a Web Analytics opt-out feature on your site (using a simple iframe), and
3) Delete old visitors logs.
To configure Privacy features in Piwik, log in as a Super User, click "Settings" then click "Privacy".

On many websites, you want to track when visitors download your brochure, a photo, a software, etc. Piwik automatically track these clicks as Downloads, and reports them under Actions > Downloads.
Piwik will automatically detect a download as a click on a link that ends with one of the following file extensions: 7z, aac, arc, arj, asf, asx, avi, bin, bz, bz2, csv, deb, dmg, doc, exe, flv, gif, gz, gzip, hqx, jar, jpg, jpeg, js, mp2, mp3, mp4, mpg, mpeg, mov, movie, msi, msp, odb, odf, odg, odp, ods, odt, ogg, ogv, pdf, phps, png, ppt, qt, qtm, ra, ram, rar, rpm, sea, sit, tar,
tbz, tbz2, tgz, torrent, txt, wav, wma, wmv, wpd, xls, xml, z, zip.
The Piwik report "Pages > Outlinks" shows the list of external URLs that were clicked by your visitors from your website pages. Piwik will track as an "outlink" all clicks on URLs that are not the same domain as the website being tracked. For example, if your visitor click on a link to "piwik.org" on your website "example.org", this will be counted as an outlink in the report.
For each outlink, Piwik will report the number of clicks, and the number of unique clicks. Unique clicks are the number of unique visitors that clicked to a given domain ; for example, if the same visitor clicked 3 times on the same outlink, it will be reported as 3 clicks and 1 unique click.

You can also use Piwik to track Search Engine Bots. For this you will need access to your web server access log files, which you can import in Piwik along with Search Engine Bots Traffic information.

Piwik can scale to millions of page views per month and/or to thousands of registered websites. If you have a few hundreds visits/page views per day, Piwik should work fine "out of the box".

Yes, the data coming from the Piwik API belongs to you and is not covered by the GPL. You can use Piwik as a service, and reuse, publish, display, modify, process the data coming from the Piwik API using the REST web service call - this is not allowed if you call the API when using Piwik as a PHP library (see how to call the API?).
See also the GPL FAQ: Is there some way that I can GPL the output people get from use of my program? For example, if my program is used to develop hardware designs, can I require that these designs must be free?
Many medium-high traffic websites successfully use Piwik to track and analyse their website behavior and performance. See this FAQ for general information about high traffic Piwik.
If you want to provide high reliability and better performance in your Piwik setup, you can load balance Piwik services on various servers. It is pretty easy to do so, but make sure you read the following documentation.
Piwik stores all tracking data, reports, users, settings, etc. in the shared mysql database. Piwik also needs to read/create files to store information, caches, temporary files:
When Piwik is used behind a load balancer, here are the steps to follow:
Piwik should then work as expected in a load balanced environment.
For example, a common way to load balance Piwik on 3 servers: Load balancer in front of (2x) webservers which are tracking/querying the (1x) Master mysql DB server. For further optimization, a (1x) UI webserver can be added, to handle all API requests, UI requests, and run the cron archiving. This server can also be doubled and load balanced.
Typically, webserver boxes would be cheap to operate servers, and the Master DB server would be bigger (eg. multiple cores, 8G memory, fast disk access), which could scale to a certain point (1M+ pages per day).
When working on the first version of Piwik, Matthieu was looking for a name that was unique, easy to write and to remember, with as few letters as possible, and for which the domain name was still available. After a few hours of deliberation and creativity, the name Piwik was born out of Matt's imagination.
The name 'Piwik' does not have a particular meaning, but we are on a mission: "To create, as a community, the leading international open source web analytics platform, that gives users full control of their data."
