Overview
Zammad is a productized open-source helpdesk platform for customer support, internal service desks, and multi-channel ticket workflows. It combines an open codebase with a commercial company providing hosted services, training, and support, so it is more than an uncommercial project. Zammad is a credible European alternative to Zendesk for organizations that want transparency and deployment control. Official company and legal pages identify Zammad GmbH in Berlin and the Zammad Stiftung as the open-source project steward.
