What is Thunder

Thunder is a Drupal distribution for professional publishers. It consists of the current Drupal functionality, lots of handpicked publisher-centric modules with custom enhancements, and an environment which makes it easy to install, deploy and add new functionality.

In 2016, the German publisher Hubert Burda Media established the Thunder Coalition, which aims at joining forces amongst publishers by sharing code and innovation power.

As members of the Thunder Coalition, publishers, industry partners, and developers develop useful modules and extensions, use them for their own purposes and share them with the Coalition by publishing them under the GNU General Public License to further enhance Thunder.

What do I get with Thunder

  • Create articles dynamically with paragraphs: Using paragraphs, you can add text with a WYSIWYG-editor, pictures, videos, Instagram or Twitter cards to your article – and change the order by dragging and dropping the content wherever you like it. Thanks to a preview mode, you get a good idea of how your article will look like in the end.
  • Schedule your content: You can plan when texts should be published, and you can also set a date to remove the article from your website. Also, you can set an expire date for images. After this, the picture will be replaced with a placeholder.
  • Improved media handling: With the help of the media browser, it’s very easy to add pictures, galleries, or videos to your article. You can upload new pictures to the media browser by just dragging and dropping. The pictures are cropped automatically and with the focal point, you can define the important part of the picture, which should be visible in every layout.
  • Mobile Friendly: With the Thunder installation, you get a responsive theme for frontend and backend. When writing an article, you can check how your text will look on different smartphones and tablets with the help of the device preview.
  • Demo Content and Guided Tour: We added demo content and a guided tour to make it easier for newcomers to understand how Thunder works. Step by step, we explain how to add an article, how to edit an article, or how to add and sort channels.
  • Flexible System: With Thunder, you get a system with a very high scalability. It's extendable with more than 2500 modules to fit every need. Plus, it's themeable.
  • Big Drupal community: Benefit from an active community with more than 100.000 user actively contributing and more than 2000 commits per week. In the Drupal and the Thunder community you'll find support if needed.

Who is doing this

The distribution is maintained by the Thunder Core Team. The Thunder Core Team are a small number of publishing experts and computer scientists.
