rukzuk is Open Source!

What does this mean?

It means that as of now the source code of rukzuk is publicly available at GitHub. Everyone with a little technical knowledge can now run the software on their own servers and participate in the development of rukzuk.

Why do we do that?

Open Source Software increases safety for users in many ways. Not only in terms of the actual IT security but not least in terms of long-term availability and reliability. These are extremely important criteria when choosing a platform with which you would like to work for a long term. Therefore, we are confident that this measure will strengthen confidence in rukzuk and extremely promote the spread.

This gives us another important unique selling point over our competitors. This is particularly interesting in light of the internationalization of rukzuk. Of course, we also hope for contributions of other developers, not least in the development of other language versions.

And how will we make money then?

Fact is: The publication of rukzuk as open source means that users with appropriate technical skills can install and use rukzuk for free. Our business model as "Software as a Service" (SaaS) is not affected by this, however. We continue to offer rukzuk as Hosted Solution with support at the known rates. The actual value is not just in the software per se but in the services around it. And this of course is also useful for the spread of rukzuk.
