The Zendesk alternative you can actually budget for
Zendesk is the most established helpdesk in the category, and for a large team with complex integrations that still matters. The catch is budgeting: AI agents are billed on the outcomes they deliver, but Zendesk doesn't publish the rate or the included allowance, and Copilot is another $50 per agent per month. Kerux prices per agent and nothing else. You connect your own AI key and pay your provider at cost.
| Dimension | Kerux | Zendesk |
|---|---|---|
| AI pricing | Bring your own API key. Pay your AI provider directly, at cost | AI agents included, then billed on the outcomes they deliver. The rate and included allowance are not published |
| Can you budget it up front? | Yes. Agents × your tier, and nothing else | Not from the pricing page; you need a sales conversation to learn the resolution rate |
| Seat pricing | Flat per agent, from $29/month | $19–$115 per agent/mo billed yearly, across Support Team to Suite Professional |
| AI assistant for agents | Included on every plan | Copilot is a separate add-on at $50 per agent/mo billed yearly |
| Bill predictability | Priced per agent only. AI volume never changes your bill | Seats are fixed; automated-resolution charges vary with volume |
What it costs in practice
5 agents on a mid tier, with an AI assistant for the team
- 5 Suite Team seats × $55
- $275
- 5 Copilot add-ons × $50
- $250
- Automated resolutions beyond your allowance
- not published
- 5 Growth seats × $49
- $245
- AI assistant for every agent
- included
- AI replies on your own key
- paid to your provider, at cost
- Zendesk seat prices are the published annual-billing rates; monthly billing costs more.
- Copilot is optional. A team that doesn't want an agent-side AI assistant wouldn't pay it.
- We deliberately show no per-resolution figure for Zendesk. Third-party sites quote one, but Zendesk doesn't publish it, so we won't state it as fact.
- Every figure verified on Zendesk's own pricing page; see the date at the foot of this page.

We'd rather you chose correctly than chose us.
Stay with Zendesk if…
Zendesk's marketplace and API surface are far beyond anything a small tool offers. If your support desk has to talk to a dozen internal systems, that depth is real and Kerux doesn't match it.
Support Team is $19 per agent per month billed yearly, undercutting Kerux's $29. If you just want ticketing without AI, Zendesk's entry tier is less expensive.
Zendesk has the compliance certifications, enterprise support and contractual machinery that large organisations require. Kerux is built for small and mid-sized teams.
Switch to Kerux if…
Kerux's whole price is agents × tier. There's no allowance to track, no overage rate to negotiate, and no sales call needed to find out what AI costs.
Copilot at $50 per agent is more than Kerux's entire Growth seat. On Kerux the AI assistance is in the plan, and the model usage is billed to you by your own provider.
Forward an email address, connect an AI key, and you have a working inbox. No implementation project.
How switching actually works
- 1Forward your existing support address to your Kerux forwarding address.
- 2Bring your help-centre articles over as .md files. The AI answers from them.
- 3Start with a low confidence threshold so every AI reply arrives as a draft.
- 4Raise it as you build trust. No contract, no cancellation fee.
Questions people ask
Zendesk says AI agents are included on every Suite and Support plan and priced on the successful outcomes they deliver, but it doesn't publish the per-resolution rate or the included allowance on its pricing page. You'd need to ask their sales team. Separately, the Copilot add-on is published at $50 per agent per month billed yearly.
It depends on what you need. Zendesk's Support Team tier is $19 per agent versus Kerux's $29, so bare ticketing is cheaper there. Once you add AI, Kerux's model, flat seats plus your own provider key at cost, is easier to predict, and the agent-side AI assistant is included rather than a $50 add-on.
No, there's no importer. The realistic path is to forward your support address to Kerux and bring your help-centre content across as Markdown. Your history stays in Zendesk.
No. Kerux has a REST API and email at its core, but nothing like Zendesk's marketplace. If your workflow depends on many third-party integrations, that's a genuine reason to stay.
