In 2016, the German publisher Hubert Burda Media therefore established the Thunder Coalition, which aims at joining forces amongst publishers by sharing code and innovation power.
The Thunder Coalition’s core product is the content management system Thunder, which is based on Drupal 8. Coalition Members develop useful modules, use them for their own purposes and share them with the community by publishing them under the GNU General Public License. Neither Hubert Burda Media nor the other publishers in the Coalition will charge anyone for their contributions. The goal is to spend less money overall by working together- and not to receive money from others.
Nonetheless, publishers who use Thunder can decide which parts of their development effort they would like to share with the public – all, some or none.
The Thunder Coalition is formed to attract as many publishers worldwide as possible – as users of the Thunder distribution and as contributors to the technology. The number of users is directly related to the richness and usefulness of the provided functionality and, hence, to the number of contributors.
