Vapi

Vapi is a developer‑first platform for creating conversational voice AI agents. With an API‑native approach and SDKs for TypeScript, Python and more, you can launch inbound or outbound call flows, integrate multilingual speech, tool‑calling, A/B testing, and bring your own transcription or LLM models. It handles scaling, real‑time audio infrastructure, and enterprise‑grade security, letting teams ship voice assistants quickly and reliably.
