With KABI.tk we created a safe and self-hosted environment for web applications and services. The name KABI is a compound of Kari and Tobi, the founder and admins of the service. We host mainly for our families and friends. Therefore some of our services don't allow a free registration. However, if you want an account, feel free to text us.
We host the Kraut.World, a 2D-adventure platform to walk around and interact with people. Check it out. You also may have your own maps to use for partying, schooling and others.
