We believe that if you build something great, you should share it. That’s why Zammad is a fully transparent open-source helpdesk system — with the full feature set, not a watered-down edition.
Full transparency. Complete control. Our entire codebase is open for everyone to inspect, extend, and self-host.
We put our cards on the table and make our work open and accessible to everyone.

Your starting point: download Zammad, explore the documentation, and connect with the community in the forum.
