Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Cresta

  • Cresta depends on the CCaaS platforms it integrates with, and NICE, Genesys and Five9 are all shipping native real-time assist and auto-QA of their own, so at renewal you may be paying twice for capability your platform vendor will bundle at a discount.
  • Pricing is not published and contracts are seat-based and annual at enterprise scale, which in practice means six-figure commitments and a procurement cycle measured in months rather than weeks.
  • Real-time guidance only pays back where conversation outcomes are measurable and repeatable, so support teams handling long, varied, low-volume cases rarely recover the licence cost.
  • Deploying real-time assist requires agents to accept on-screen prompting mid-call, and contact centres with strong union representation or experienced tenured agents frequently see adoption resistance that no amount of model quality fixes.
  • Automated quality scoring changes what agents are measured on, and organisations that switch from human QA without rewriting their evaluation rubric and appeals process create industrial-relations problems that surface months after go-live.

Answered from the vendors’ own pages

Cresta: Does Cresta replace my contact centre platform?

No. It is designed to sit on top of NICE, Genesys, Five9, Amazon Connect and similar platforms, which is why it is chosen where a full CCaaS migration is not feasible.

Zendesk Chat: Can Messaging be used for live, session-based conversations or asynchronous chats?

Both. Messaging supports real-time sessions for fast help as well as ongoing asynchronous conversations, so customers can chat at their own pace and agents stay flexible.

Source
Cresta: What does it cost?

Cresta does not publish pricing. Contracts are seat-based and annual, and at the enterprise scale it sells into they are typically six figures per year.

Zendesk Chat: Do agents need a separate tool or tab to use Messaging?

No. Messaging is built right into the Zendesk Agent Workspace, so agents can manage conversations seamlessly without switching tools or tabs.

Source
Cresta: Is it viable for a contact centre under 100 seats?

Rarely. The commercial model, implementation effort and required outcome measurement all assume several hundred seats or more.

Zendesk Chat: How do I know if my AI agents are handling my tickets effectively?

Zendesk QA automatically reviews all conversations, enabling performance tracking and continuous improvement of AI and agent support.

Source
Cresta: Who owns Cresta?

It is an independent venture-backed company, having raised roughly 282 million USD in total including a 125 million USD Series D in November 2024 co-led by World Innovation Lab and the Qatar Investment Authority.

Zendesk Chat: Once I build an AI agent, can I deploy it across more than one social channel?

Yes. Build your AI Agent once and deploy it to web, mobile, and social messaging channels like WhatsApp, Facebook, and more.

Source
Zendesk Chat: Why should I switch from legacy live chat to Messaging?

Messaging enables users to replicate and enhance live chat experiences by leveraging AI agents and omnichannel routing capabilities.

Source
Zendesk Chat: Can I build something custom or go beyond the out-of-the-box experience?

Absolutely. With access to the Zendesk messaging platform, you can create fully custom experiences that fit your unique business needs.
