Source: https://vapi.ai
Can Vapi be self-hosted?

Source: https://vapi.ai
What does Vapi integrate with?
We have confirmed 14 integrations for Vapi, including Twilio, Google Business Messages / RCS, OpenAI, Anthropic, Groq, Eleven Labs, Google Cloud and Azure, plus 6 more. This is what we could verify from public sources, so the vendor may support others we have not indexed.
Source: https://vapi.ai
What security certifications does Vapi have?
We have independently confirmed SOC 2 and HIPAA for Vapi. Certifications we do not list are ones we have not been able to verify from public sources, which is not the same as Vapi 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 Vapi, not the verdict.
