Why KABI.tk?

With KABI.tk, we created a safe and self-hosted environment for web applications and services for our families and friends.

Considering that while using any commercial product that you aren’t paying for, you are the product – by selling your data and privacy. We provide open-source software and web applications for chatting, telephoning, videoconferencing, e-mailing and file storage in the cloud. Free of advertising and safely on our own servers. 

Therefore, most of our services on KABI.tk are limitated to approved users. To participate you need an invitation. If you have any questions, feel free to contact us.
