The short version

  • 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.; Plain foundation plan limited to 2,000 credits per month may be restrictive for high-volume teams
  • They diverge on capability: Alvaria covers Compliant outbound dialling, Plain covers Multi-channel consolidation.
  • 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.

Plain

  • Foundation plan limited to 2,000 credits per month may be restrictive for high-volume teams
  • Pricing increases significantly from Foundation to Horizon ($35 to $299 per month)
  • No published pricing for Frontier (custom) plan
  • Additional seat costs ($99 per seat) add up for larger teams
  • Credit-based system requires monitoring usage to avoid overages

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.

Plain: What is included in the Foundation plan?

The Foundation plan ($35/month per seat) includes 2,000 credits per month, support for Slack and email, Ari AI agent, Linear and Jira integrations, and Help Center access. Up to 5 seats are included.

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.

Plain: Can I use Plain with Microsoft Teams?

Yes, Microsoft Teams integration is available on the Horizon plan ($299/month) and higher.

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.
