What is Vapi?
Vapi is a developer platform for building, testing, deploying, and scaling voice AI agents that can make and receive phone calls. It is designed to handle the underlying infrastructure so teams can focus on the voice experience, conversation flow, and business outcome. The platform emphasizes fast setup, real-time orchestration, monitoring, and integrations, making it suitable for shipping voice products quickly.
The website positions Vapi as an API-first platform for developers and enterprises that need human-like voice agents at scale. It supports use cases such as inbound support, outbound selling, lead qualification, and other phone-based workflows. Vapi highlights multilingual conversations, low latency, and enterprise-grade configurability as core parts of the product.
Vapi also places a strong focus on production readiness. The site highlights built-in guardrails, support for telephony and integrations, and tooling for tracking performance across calls so teams can improve agent behavior over time. It is framed as a unified platform for orchestration, monitoring, and deployment rather than just a thin SDK.
The product is aimed at startups, developers, and large organizations that want to automate or augment customer conversations. The website also stresses enterprise capabilities such as SSO, OAuth, RBAC, reserved capacity, uptime guarantees, and compliance support, which suggests it is built for both experimentation and high-volume operational use.
Vapi pricing
Pricing model: Paid
Vapi’s starter pricing is $0.05 per minute for calls, billed prorated to the second. The website says transcriber, model, voice, and telephony costs are charged at cost, and users can bring their own API keys so Vapi makes requests on their behalf. Every new account gets $10 in free credits to start testing voice workflows, and no credit card is required to begin. For larger deployments, Vapi offers Enterprise plans with higher concurrency and rate limits, 24/7 support, a shared Slack channel, included minutes with volume pricing, and engineering calls several times per week.
