Kerux vs Zendesk

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: every automated resolution bills $1.50 on a committed volume or $2.00 pay-as-you-go, 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.

  • 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.
  • Resolution charges are left out of the total because they depend on your volume; the per-resolution rates are Zendesk's own.
  • Every figure verified on Zendesk's own pricing page; see the date at the foot of this page.

Which one should you actually pick?

We'd rather you chose correctly than chose us.

Stay with Zendesk if…

You need deep integrations and an app ecosystem

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.

You want the cheapest possible seat and no AI

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.

You're an enterprise with procurement requirements

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…

You want to know your bill before you commit

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.

You don't want AI as an upsell ladder

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.

You want to be running today

Forward an email address, connect an AI key, and you have a working inbox. No implementation project.

How switching actually works

  1. 1Forward your existing support address to your Kerux forwarding address.
  2. 2Import your Zendesk history from Settings → Import tickets: conversations, customers and internal notes come across with their original dates. The AI never answers imported tickets.
  3. 3Bring your help-centre articles over as .md files. The AI answers from them.
  4. 4Start with a high confidence threshold so the AI only sends what it's sure of.
  5. 5Raise it as you build trust. No contract, no cancellation fee.

Questions people ask

Zendesk's pricing page lists $1.50 per automated resolution on a committed volume and $2.00 pay-as-you-go, on top of seats, and only bills a resolution the AI handles without a human. 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.

Yes. Settings → Import tickets connects with your Zendesk subdomain, an admin email and an API token, and copies your tickets, customers and internal notes with their original dates. Help-centre content comes across as Markdown. Re-running it skips anything already imported.

No. Kerux connects to Slack, Shopify, Linear, Jira and Claude, and has a REST API, but nothing like Zendesk's marketplace. If your workflow depends on many third-party integrations, that's a genuine reason to stay.
