Zammad
Easy to use but powerful open-source support and ticketing system.
Zammad is a web‑based, open‑source helpdesk and customer‑support platform that consolidates communication from email, chat, telephone and social media into a single ticketing system. It provides tools for tracking, assigning and resolving inquiries, allowing support teams to stay coordinated while handling multiple channels. The software runs on self‑hosted servers and is available under the AGPL‑3.0 license, with binary packages for Debian, Ubuntu, CentOS and Docker, as well as Helm charts for Kubernetes deployments.
The system includes a REST API for integration, documentation, and a community‑driven development model managed by the Zammad Foundation. It is maintained by Zammad GmbH in collaboration with contributors, and the code is hosted on GitHub. Continuous integration, Docker images, and package repositories support stable releases and ongoing updates.
Zammad targets organizations that need a free, self‑hostable ticketing solution without subscription fees, offering a feature‑rich alternative for managing customer support across diverse communication channels.
