The short version

  • Only Rasa has a free tier, so it costs nothing to try first.
  • Each has a real cost: Alvaria the October 2025 restructuring wrote off more than 75% of roughly $950 million of debt and handed control to a lender group led by Nut Tree Capital, so the owner is now a credit fund optimising for debt recovery rather than a growth investor, which is a real signal about future research spending.; Rasa free Developer Edition caps conversations at 1,000 external or 100 internal per company per month
  • They diverge on capability: Alvaria covers Compliant outbound dialling, Rasa covers NLU engine.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

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

Alvaria

  • The October 2025 restructuring wrote off more than 75% of roughly $950 million of debt and handed control to a lender group led by Nut Tree Capital, so the owner is now a credit fund optimising for debt recovery rather than a growth investor, which is a real signal about future research spending.
  • The September 2024 spin-out of the workforce management suite to the revived Aspect brand means a buyer who wanted an integrated CX plus WFM stack now signs two contracts with two companies, and first-party integration is no longer guaranteed by a single roadmap.
  • Digital channels are underbuilt: reviewers report CXP has no support for WhatsApp, RCS or Viber, and no ability to bring your own carrier for email and SMS, which blocks messaging-first and many international deployments.
  • Legacy on-premise upgrades are described by reviewers as long and painful, with a large footprint and hard-to-learn interdependencies, so migration cost is a substantial hidden line item on any modernisation.
  • Alvaria is slower than peers to certify new Nuance speech recognition and text-to-speech releases, so speech quality in your IVR runs behind whatever the underlying engine has shipped.
  • There is no published pricing, no trial and a mixed on-premise and cloud licensing model, making like-for-like comparison against Genesys, Five9 or NICE genuinely difficult and lengthening the evaluation.

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

Alvaria: Was Alvaria renamed to Aspect?

No. It split. Aspect is the spun-out workforce management business at aspect.com. Alvaria kept outbound and contact centre infrastructure. Confusing the two points procurement at the wrong vendor.

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.

Source
Alvaria: Who owns Alvaria now?

Since October 2025, a lender group led by Nut Tree Capital, following an out-of-court debt restructuring. Abry Partners no longer controls the company.

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
Alvaria: Can I still buy on-premise?

Yes. Cloud, on-premise and hybrid deployments are all offered, which is one of the few remaining reasons to choose Alvaria over a pure CCaaS vendor.

Rasa: What is the difference between Rasa Pro and Enterprise?

Rasa Pro includes the pro-code framework with advanced NLU and multi-LLM management. Enterprise adds full platform access, 24/7 support, dedicated Customer Success Manager, and business reviews.

Source
Alvaria: Does it support WhatsApp or RCS?

Not per current reviewer reports on CXP. Voice and some SMS only, with no bring-your-own-carrier option for email and SMS.
