Unified web‑based helpdesk for email, chat, phone, social
Zammad streamlines customer inquiries across email, chat, phone, and social media, offering a web‑based ticketing system with collaborative tools, REST API, and easy Docker/Kubernetes deployment.
Zammad is a web‑based helpdesk designed for teams that need to manage customer conversations from multiple channels—email, live chat, telephone, and social media—in a single, searchable interface. It provides ticket creation, assignment, and internal notes, enabling agents to collaborate efficiently while keeping customers informed.
The platform includes a full REST/GraphQL API for custom integrations, multi‑language support, and role‑based permissions. It ships as Docker images and a Helm chart, allowing straightforward deployment on containers or Kubernetes clusters. The source code is released under AGPL‑3.0, and a commercial cloud service is available for organizations that prefer managed hosting.
Ideal for small to medium support teams, DevOps‑savvy organizations, and any business that wants full control over its support stack while avoiding vendor lock‑in. Community contributions and a dedicated foundation ensure ongoing development and security updates.
When teams consider Zammad, these hosted platforms usually appear on the same shortlist.
