Zammad

Zammad is an open-source, web-based helpdesk and customer support ticketing system that provides professional customer service capabilities with the flexibility of self-hosted deployment. The platform supports ticket management across email, phone, chat, Twitter, Facebook, and Telegram, consolidating all customer interactions into a unified agent interface. Zammad provides a knowledge base for self-service customer support, SLA management with escalation rules, canned responses for efficient agent workflows, time tracking per ticket, and comprehensive reporting dashboards. The platform features a powerful search engine that indexes all ticket content, customer history, and knowledge base articles for instant information retrieval. Ticket workflows can be automated with triggers that execute actions based on conditions, macros for multi-step agent operations, and scheduled jobs for recurring maintenance tasks. Zammad supports LDAP and Active Directory integration for enterprise user management, SSO through SAML and OAuth, and a REST API for integration with external systems. The user interface is modern and responsive, providing a significantly better experience than many open-source helpdesk alternatives. Zammad can be self-hosted on-premises or deployed through managed hosting, giving organizations complete control over their support data. The open-source community edition includes all core features with no artificial limitations, while the hosted subscription adds managed infrastructure and priority support.
