Head to head

KrispCall vs OpenPhone

Same facts, side by side: starting price, free tier, MCP, API and what each one is actually built for.

KrispCall

$12/user/mo

KrispCall is an AI cloud phone with Starter at $12/user/month billed annually ($15 monthly). Advance is $32 annual and Max is $48 annual. Call minutes and SMS are billed on top of the seat.

Where KrispCall fits

  • Solo agents and shops under 5 seats that want a US/UK/CA number for $12/user/mo
  • Sales teams that need a power dialer and bulk SMS on Advance
  • Support desks that want IVR, recording, and Slack or HubSpot in the same callbox
  • Teams calling internationally that will buy minutes separately

OpenPhone

$15/user/mo 7 day free trial

OpenPhone now sells as Quo. Starter is $15 per user per month when billed annually ($19 month to month). A 7-day trial is on the pricing page. Recruiter use is a shared req line, SMS screens, voicemail transcripts, and API writeback.

Where OpenPhone fits

  • Recruiting teams that need a shared candidate line and SMS without a full contact-center suite
  • Desks that want Sona AI on the base plan rather than an add-on dialer bot
  • TA ops that will use the Quo API to push voicemail and SMS into an ATS
  • US and Canada calling teams that can live on Starter numbers and Fair Usage

Where they pull apart

KrispCall

Stands out: Every plan includes one free US, UK, or CA number per user plus HubSpot, Salesforce, Zapier, Pipedrive, Intercom, Slack, Zoho, and monday.com among 100+ integrations.

Watch out: Starter is capped at 5 users. API and webhook access is listed as Coming Soon. The 14-day refund is a money-back window on the subscription, not a free trial, and usage add-ons are non-refundable.

Not the right fit for

  • Contact centers that need a public API today rather than Coming Soon
  • Buyers who want unlimited seats on the cheapest Starter tier

OpenPhone

Stands out: Every plan includes one local or toll-free number per user, US and Canada calling and SMS, voicemail transcripts, the Quo API, and the Sona AI agent with 1,000 automation credits. ChatGPT and Claude MCP is listed on the cloud-VoIP feature page. Capterra (still filed as OpenPhone, titled Quo) is 4.2 from 64 reviews.

Watch out: Monthly Starter is $19, not $15. Business and Scale AI summaries, call analytics, and advanced CRM integrations start at $23/$35 per user per month annual. Extra numbers are $5/month. US texting needs 10DLC registration fees on top.

Not the right fit for

  • Global recruiting teams that need non-US/Canada calling as the default
  • Enterprises that want a carrier-grade CCaaS with quoted seat minimums
