Open Source.
No strings attached.

We believe that if you create something great, you should share it. That’s why Zammad is an open-source helpdesk system — with the full feature set, not a watered-down edition.

Proudly Open Source

Full transparency. Complete control. Our entire codebase is open for everyone to inspect, extend, and self-host.

Free Code for Everyone

Every new line of code goes straight into our public repository. We’ve learned a lot by studying other developers’ code — discovering valuable ideas, tips, and clever solutions along the way. That’s why, with our open-source ticketing system, we give just as much back — hoping it helps others build great things, too.

Community Driven

For us, true innovation comes from interacting with thousands of users worldwide. Their ideas, feedback, and unique use cases are continuously incorporated into the further development of Zammad. This dialogue makes our helpdesk a little better with every release.

True Sovereignty

We believe that your data and processes should belong to you alone. With Zammad, there is no vendor lock-in and no dead ends. Since the entire code is open source, you retain full control and the freedom to run your system exactly where you want it—today, tomorrow, and ten years from now.

We put our cards on the table and make our work open and accessible to everyone.
