How much does Retell AI cost?
Retell AI does not publish its prices. Pricing is quoted on request, across 2 plans (Pay-as-you-go and Enterprise), so the figure depends on your seat count and requirements. We record this as a pricing-transparency signal rather than guessing a number. Pricing changes often, so verify at source before relying on it.
What platforms does Retell AI support?
Retell AI supports the web, iOS and Android. Platforms we have not confirmed are simply not listed here rather than ruled out.

Can Retell AI be self-hosted?
We have only confirmed a cloud / SaaS deployment for Retell AI, so it appears to be vendor-hosted. If a self-hosted option exists we have not found it documented publicly.
Source: https://www.retellai.com
What does Retell AI integrate with?
We have confirmed 45 integrations for Retell AI, including Twilio, Vonage, Telnyx, Salesforce, HubSpot, Zoho CRM, Zapier and n8n, plus 37 more. This is what we could verify from public sources, so the vendor may support others we have not indexed.
Source: https://www.retellai.com
What security certifications does Retell AI have?
We have independently confirmed SOC 2, ISO 27001, HIPAA and GDPR for Retell AI. Certifications we do not list are ones we have not been able to verify from public sources, which is not the same as Retell AI not holding them. Always confirm compliance directly before you rely on it.

The vioscaleAI score: one lens on the evidence
Not user reviews and not a paid placement: a confidence-weighted blend of the independent signals below (adoption, activity, security posture, and more), which you can sort and re-weight yourself. Vendors can correct their listing but can never move their rank, and stars are weighted low as a vanity metric. It is one way to read the evidence for Retell AI, not the verdict.
