Vapi

Vapi is a voice AI platform that allows developers to quickly build, test, and deploy voicebots for any use case like customer support, sales, lead generation, booking systems, and more. Its self-service dashboard and client SDKs for web, mobile and Python make it easy to create custom voice assistants that can make and receive calls. Vapi automatically optimizes for low latency with techniques like intelligent caching and optimized GPU inference. Multiple paid pricing tiers are available depending on usage requirements, with documentation, examples, and getting started guides to support developers getting set up.
