HESK is a ticket form that works. The trouble starts when support stops being a form.
HESK is small, cheap and does not pretend otherwise – a PHP ticket system you drop on a server and forget. Teams outgrow it in a predictable way: the email side is thin, there is no real reporting, and the knowledge base is a list rather than something the system helps you use.
Strengths you can check – to the point.
Your data is stored and processed in Germany.
The AI assistant runs on your own server – ticket content is never sent to an external AI service.
Tenant separation, export and deletion functions and a data processing agreement are built in.
One clear price per booked seat – no feature ballast, no hidden add-ons.
An uncluttered interface with a guided start – expensive training is not needed.
Team questions and an automatic wiki keep what you know on the ticket instead of scattered across tools.

What counts is the current information published by each vendor.
Usually at the mailbox. Support that arrives as email needs replies that go back as email, matched to the right case by reference rather than by subject line – and that is where a form-first system starts to leak.
rapidFOX connects the mailbox in minutes, keeps every reply on the case, and adds what a growing team asks for next: SLA with a traffic light, a knowledge base the AI actually uses, and honest reporting.
The move is deliberately undramatic. You start a free trial that comes with sample data and connect your support mailbox over IMAP/SMTP in a few minutes. From then on every incoming email becomes a ticket, and replies go back out as ordinary email.
What a clean switch looks like step by step is in the guide Introducing a ticketing system.
The rapidFOX AI assistant runs on your own server: drafting replies, shortening them, turning notes into full messages and suggesting solutions – ticket content is never sent to an external AI service. On or off whenever you like, and a person always approves.
Because the difference shows up in hours, not in features. If HESK covers what you need, keep it – that is a genuine recommendation, not a hedge.
No. It is an operated service on servers in Germany. If running it yourself is the requirement, HESK or Zammad are the honest answers.
Yes. The trial runs for seven days with sample data, and you can connect a second mailbox rather than moving the main one. Nothing has to be switched off first.
rapidFOX costs one fixed price per booked seat, with every function included and no tiers. What HESK costs depends on the plan and the add-ons you need – compare it against the list price of the tier that actually covers your requirements.
