Zammad

Zammad is a web-based, open-source helpdesk and customer support platform for handling customer inquiries and tickets. It brings communication from email, chat, telephone, and social media into one system so support teams can work from the same place instead of juggling separate channel tools.

Ticketing sits at the center, turning inquiries from every channel into trackable tickets that the whole team can see and resolve together. A REST API opens the system to integration with other tools, and self-hosting gives organizations full control over their support data.

Zammad runs on your own infrastructure through Docker container images, a Helm chart for Kubernetes, or DEB and RPM packages. It is licensed under GNU AGPLv3 and stays open source, with the source code owned by the independent Zammad Foundation and development carried out by Zammad GmbH together with the community.
