What is Vapi?
Vapi is a developer platform for building, testing and deploying voice AI agents that handle phone and web calls. You can configure the voice, the conversation flow, telephony and integrations. Vapi runs the infrastructure, so a team can go from a prompt to a production agent quickly.
Common uses are customer support, lead qualification and appointment scheduling. The platform includes real-time monitoring, call simulation for testing, and guardrails. It supports telephony through Vapi SIP, Twilio, Vonage and Telnyx, as well as WebSockets and WebRTC.
Pricing is usage-based. Vapi charges a $0.05/min hosting fee, and model providers such as Deepgram, OpenAI and ElevenLabs are passed through at cost. Optional success packages add support, concurrency and SLAs. The platform fits individual developers as well as enterprises, with SOC 2, HIPAA and PCI compliance, SSO and RBAC.
