About
Vapi is an API-first voice AI platform for building production phone agents. Developers compose STT, LLM, and TTS providers freely (OpenAI, Anthropic, 11Labs, Deepgram, Assembly), point at any LLM, and ship sub-500ms latency calls. The 4,200-point configuration surface is the differentiator — most teams pick Vapi when they want to control every layer rather than accept defaults.
Best for: Developers and product teams building voice features into their own product. Pick Vapi when you need fine-grained control over the full STT-LLM-TTS pipeline and aren't afraid to write code.
