Vapi review

Vapi is built for developers who want to assemble their own stack. You pay a pre-paid $0.05 per minute hosting fee, and transcription, LLM and voice providers are passed through at cost from a full model catalog. The pricing calculator shows the effect: at 1,000 minutes with Deepgram, OpenAI and ElevenLabs the estimate is $82 to $129 a month. Usage-only accounts get $5 in credits, one phone number and 4 concurrent calls; the $29 Core package raises that to 10 calls and five numbers, and extra lines cost $10 each per month. The developer tooling is the strongest in this list: a CLI, config as code with assistants and tests in git, simulations, and Squads that hand a caller between specialized assistants with context. Vapi telephony, SIP, WebSockets and WebRTC transport are free, with Twilio, Vonage and Telnyx billed by the carrier. The trade-off is setup effort and HIPAA at $2,000 a month.
