The short version

  • Only Krayin 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.; Krayin it is far less mature than EspoCRM, SuiteCRM or Vtiger, with thinner reporting, weaker forecasting and fewer built-in integrations, so evaluations that start from a feature checklist will not favour it.
  • They diverge on capability: Calabrio ONE covers Intelligent forecasting, Krayin covers Lead pipelines.
  • 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.

Krayin

  • It is far less mature than EspoCRM, SuiteCRM or Vtiger, with thinner reporting, weaker forecasting and fewer built-in integrations, so evaluations that start from a feature checklist will not favour it.
  • Practical functionality such as certain telephony, messaging and marketing connectors sits in paid marketplace extensions from Webkul, so the free CRM plus the extensions you actually need is not free.
  • The roadmap is controlled by a single services company whose revenue depends on selling implementation and extensions, so there is a structural incentive against making the core complete.
  • You are responsible for the whole operational burden: PHP and MySQL hosting, backups, security patching, mail deliverability and upgrades, and a botched upgrade of a customised install is your problem alone.
  • The cloud hosting page does not publish prices, so the managed option that would remove that burden cannot be budgeted without contacting sales, which undercuts the transparency the open licence otherwise offers.

Answered from the vendors’ own pages

Calabrio ONE: Is Calabrio still a separate product from Verint?

It is still sold and supported under the Calabrio name, but the companies merged under Thoma Bravo ownership in November 2025 and calabrio.com now redirects to verint.com.

Krayin: Is Krayin really free?

The CRM itself is MIT licensed with no user limit and no enterprise edition. Premium extensions, managed hosting and custom development from Webkul are paid.

Calabrio ONE: Will Calabrio customers be forced to migrate to Verint?

Verint has publicly committed to supporting and enhancing Calabrio solutions with no forced migration. Get that commitment written into your contract term rather than relying on the statement.

Krayin: Who maintains it?

Webkul Software of Noida, India, the same company behind the Bagisto open source ecommerce platform.

Calabrio ONE: Does it replace my contact centre platform?

No. It sits on top of your CCaaS or telephony platform and handles workforce management, recording and quality.

Krayin: What do I need to run it?

A standard LAMP or LEMP stack with PHP, Composer and MySQL or MariaDB. Any host that runs Laravel will run Krayin.

Calabrio ONE: What does it cost?

Nothing is published. Independent reporting puts the entry point near 75 US dollars per agent per month, rising with quality and analytics modules.

Krayin: How does it compare to EspoCRM?

EspoCRM is more mature with deeper reporting and a longer track record. Krayin is easier for a Laravel developer to extend and has a more permissive licence.
