Reusing Matomo in any way is allowed as long as you respect the GPL license and the Matomo Trademark guidelines. Below you will find more information and pointers.
Using Matomo to track users in your commercial website or apps
The Matomo trademark
Please see the Matomo Trademark page for more details about how to reuse the name Matomo in your modified version of Matomo.
Customising Matomo sourcecode
If your product, software, or website uses Matomo (Piwik) but all the code (including your modifications) stays within your company or server, you have the freedom to keep your code and not be bound to the GPL License. For example, you can change the header and footer to reflect your brand, change the colors, or add new features and plugins on your own copy of Matomo.
Distributing/selling the sourcecode
If you distribute a modified version of Matomo, or a software that includes Matomo as a module, then you must give access to the code source and publish all the code under the GPL. You may want to learn more about the GPL License and look at the GPL FAQ.
Distributing a custom plugin for Matomo
If you create and distribute a new custom plugin built for Matomo, as a Plugin developer it is allowed to release the plugin under a different license than GPL, as long as the plugin is distributed separately from the Matomo platform. For example some third party plugins from our open Marketplace may be released under a different license than GPL. Similarly individual components, libraries and plugins within a Matomo instance may be available for reuse under a different license. Please refer to the LEGALNOTICE file included in the distribution.
Reselling Matomo with a custom branding (white label)
When you resell Matomo to customers, you may be interested in our White Label product which removes all the branded aspects of Matomo and lets you provide an immersive experience and your own custom brand.
