What it is

Zammad collects customer messages from several channels into tickets that your agents answer from one interface. The source code is owned by the independent Zammad Foundation, while Zammad GmbH does most of the development and sells hosting. A REST API and a developer manual are documented for connecting it to other systems.

Who it's for

It fits small to mid-size support or IT help desks that want to own their ticket data or choose a German-hosted cloud. It is a poor fit if you have nobody to run a server and do not want to pay for the hosted plans.

Key features

Multi-channel ticket inbox

Email, chat, telephone and social media conversations land in one ticket queue.

Docker and Kubernetes installs

The README lists Docker images, a Helm chart for Kubernetes and DEB/RPM packages.

Documented REST API

An API reference is published at docs.zammad.org for integrations.

Hosted option in Germany

Zammad GmbH runs paid cloud instances in German data centers with a free trial.

Foundation-owned source

The code belongs to the Zammad Foundation, independent of the company that sells hosting.

Optional AI features

Hosted Professional and Plus plans can switch on AI features such as ticket summaries, billed per call.

How to start

Up and running in 3 steps

2
Or skip hosting: start the free trial instance from the cloud service linked in the README at https://zammad.com/en/getting-started.
3
Connect your first channel, then use the REST API reference in the docs if you need links to other tools.

Our honest verdict

What's great

  • The README lists several install routes: Docker images, a Helm chart, and DEB/RPM packages, so it fits different server setups.
  • The source is owned by the Zammad Foundation rather than the vendor, which matters if you worry about the licence being changed later.
  • You can choose between running it yourself and a hosted plan from 7€ per agent per month, without switching products.
  • Hosted plans state German data centers and ISO27001 certification, useful for teams with European data rules.

Where it falls short

  • Self-hosting means running the application stack yourself, including backups and updates; the README itself points to its cloud service for people who dislike that work.
  • The AGPL-3.0 licence requires you to share source changes if you offer a modified version as a network service.
  • Hosted AI features are optional and cost an extra 0.03 euro per AI call on top of the per-agent price.
  • Hosted plans cap agents (5 on Starter, 35 on Professional), and chat, SLAs and a knowledge base only start on higher tiers.
