The short version

  • Only OneSignal has a free tier, so it costs nothing to try first.
  • Each has a real cost: Calabrio ONE ownership changed in November 2025 when Thoma Bravo took Verint private and merged it with Calabrio, so the product is no longer the independent alternative to Verint that most shortlists put it on for, and roadmap priorities across two overlapping suites will be decided by one company.; OneSignal free plan email sends cap at 10,000 per month and web push is capped at 10,000 subscribers per send, per onesignal.com/pricing (Aug 2026)
  • 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.

Calabrio ONE

  • Ownership changed in November 2025 when Thoma Bravo took Verint private and merged it with Calabrio, so the product is no longer the independent alternative to Verint that most shortlists put it on for, and roadmap priorities across two overlapping suites will be decided by one company.
  • The combined business has run substantial layoffs following the buyout, which raises real questions about support responsiveness and module investment that a prospective buyer should press on in contract negotiation.
  • Pricing is quoted per agent per month, commonly cited from around 75 US dollars, with analytics and quality sold as separate modules, so the headline figure understates a full suite deployment considerably.
  • There is no free trial and no self-service tier, meaning evaluating the forecasting engine against your own historical data requires a sales-led proof of concept measured in weeks.
  • The forecasting and scheduling engine assumes an operations team that can configure shift rules, service level targets and skill routing correctly; deployed by a team without that expertise it produces schedules people override manually, which negates the reason to buy it.

OneSignal

  • Free plan email sends cap at 10,000 per month and web push is capped at 10,000 subscribers per send, per onesignal.com/pricing (Aug 2026)
  • Professional and Enterprise plans require custom annual contracts with no published rate, per onesignal.com; SMS/RCS messaging and dedicated IPs are gated behind the Professional tier
