  • Each has a real cost: 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.; Rasa free Developer Edition caps conversations at 1,000 external or 100 internal per company per month
  • They diverge on capability: Cresta covers Real-time agent assist, Rasa covers NLU engine.

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.

Rasa

  • Free Developer Edition caps conversations at 1,000 external or 100 internal per company per month
  • Rasa Pro and the Business Plan (Pro plus Studio) are not priced on the site and require contacting sales

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.

Rasa: Does Rasa offer a free version?

Yes. Rasa offers a free Developer Edition with one bot per company, up to 1,000 external conversations per month, and free community support.

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.

Rasa: What support is included with Rasa's free tier?

The free tier includes community forum support with responses from Rasa community members. Paid tiers add premium support with enhanced response times.

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.
