Thunder is a web-based open-source Content Management System setting new standards for publishers’ CMS. It is based on Drupal, enabling its users to benefit from the Drupal community's continuous development efforts, as well as specific modules contributed by Hubert Burda Media, other publishers and industry partners – the Thunder Coalition.

With the Thunder Coalition, Burda is establishing a culture of collaboration and sharing within the publishing industry. Thunder is 100% non-profit – it was released as open source software under the GNU General Public License. All publishers can use and enhance the system with no licensing cost.

Join the Thunder Coalition!

We believe that publishers do not compete through technology, but through content and brands. That’s why we decided to release Thunder as open-source software and started the Thunder Coalition to join forces by sharing code and innovation power.

Coalition Members develop valuable modules, using them for their own purpose and sharing them with the community under the GNU General Public License. The Coalition discusses feature requests and offers, celebrates new launches, and is a platform for programmers and executives in the publishing industry.
