Zammad review
A flexible help desk for technical teams that want open-source control.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Zammad is a web-based help desk and ticketing platform for organizations handling customer and internal support requests. It brings conversations from multiple channels into tickets, provides a customer-facing web interface, and supports shared inbox workflows. The product is available as free open-source software for self-hosting, alongside hosted plans and support contracts. Its audience includes technical teams, IT service desks, startups, small and medium-sized businesses, and enterprises that want control over how support is managed.
Channel coverage and ecosystem fit are central strengths. Zammad supports email, web forms, SMS, chat, Telegram, Facebook, and WhatsApp, with integrations for GitHub and GitLab. Its REST API supports token and OAuth2 authentication, while web, Linux, self-hosted, and API access cover several deployment and extension paths. Full-text search and attachment-content search with Elasticsearch help teams work across larger ticket collections. These capabilities make Zammad a practical fit for organizations that need support operations to connect with technical workflows rather than remain limited to a shared email inbox.
The feature depth extends from daily ticket handling into structured service management. Service-level agreements include escalation times, triggers apply conditions and actions, and schedulers support time-based jobs and email filters. The knowledge base offers public, staff-only, and draft visibility, while AI agents, ticket summarization, and writing assistance add newer workflow options. Plan scope changes from a five-agent Starter v2 tier to Professional v2 with 35 agents and Plus v2 with unlimited agents; higher tiers add channels, workflows, and multilingual knowledge base support. Zammad suits teams that value customization and breadth. Teams seeking only a basic, narrow help desk may prefer a simpler tool.
