The solution for large-scale Online-Discussions

Welcome to D-BAS - the Dialog-Based Argumentation System. It offers a clear discussion structure, a modern web interface, a decentralized moderation system and is easy to use for everyone!

We've got what you need: Structured Discussions!

With the rise of the Internet, we now have a basic infrastructure, which makes participation easier for everyone and independent of space and time. Online participation offers many possibilities for users as well as operators, has an impact on political and administrative decisions and has the potential to strengthen the acceptance and the quality of them. We offer a novel approach for large-scale online-discussion. Feel free to try it out now!


We are aware of the fact, that D-BAS is not suitable for every online discussion, of course! But we give our best to deliver a software which can support rational online argumentations! You should give D-BAS a try if:

  • your discussion is very controversy;
  • your participants are willing to debate;
  • some participants will come back;
  • you need to support the discussion
  • you want a structured result of given arguments.

That's interesting, isn't it?
