The short version

  • Only EspoCRM 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.; EspoCRM the AGPLv3 licence obliges you to publish source modifications if you make the modified software available over a network, which blocks resellers who want to offer a customised hosted version without opening their code.
  • They diverge on capability: Calabrio ONE covers Intelligent forecasting, EspoCRM covers Entity manager.
  • 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.

EspoCRM

  • The AGPLv3 licence obliges you to publish source modifications if you make the modified software available over a network, which blocks resellers who want to offer a customised hosted version without opening their code.
  • Cloud plans carry seat minimums of three, five and ten users, so a two-person consultancy pays for three seats and a small team wanting the Ultimate features pays for ten.
  • Record ceilings are real on the cheaper cloud tiers, with Basic capped at 100,000 records, and hitting the cap means a tier upgrade rather than a small overage charge.
  • Marketing automation, sequences and native telephony are thin compared with HubSpot or Zoho, so most deployments end up wiring in a separate mailing tool and a separate dialler.
  • Self-hosting shifts the entire cost to your own team: PHP version upgrades, database backups and security patching are yours, and a neglected instance becomes an internet-facing liability holding your customer list.

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.

EspoCRM: Is the self-hosted version really full featured?

The core CRM is, but several paid extension packs including Advanced Pack for reports and BPM are sold separately as one-off purchases and are not in the free download.

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.

EspoCRM: What are the cloud seat minimums?

Three users on Basic, five on Enterprise and ten on Ultimate, so the advertised per-user rate is not the smallest bill you can pay.

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.

EspoCRM: What does it need to run?

PHP, MySQL or MariaDB and a web server. It installs on ordinary shared hosting or a small VPS, which is unusual for a modern CRM.

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.

EspoCRM: Can I move from cloud to self-hosted later?

Yes. EspoCRM states customers own their database and data files, so an export and reinstall is possible, though you take on all maintenance when you do.
