Vapi review
★ 4.1/5AI voice platform
Developer-first voice AI platform for building, testing, and deploying low-latency phone and voice agents. Vapi orchestrates speech-to-text, an LLM, and text-to-speech behind one API, handling telephony, turn-taking, interruptions, and tool calling so you wire in your own providers.

Best for voice agents. Vapi starts $0.05/min (platform fee; +model & telephony pass-through) on a per-minute usage (platform fee + model & telephony pass-through) model. Take a 1,000-minute month of outbound calls. The headline platform fee is 1,000 x $0.05 = $50, but that is only Vapi's slice. On top you pay pass-through: transcription ~$0.01/min ($10), LLM ~$0.02 to $0.20/min (say $0.06 avg = $60), voice/TTS ~$0.04/min ($40), and telephony ~$0.01/min ($10). All-in that is roughly $50 + $120 = ~$170/mo, about $0.17/min effective. Most real deployments land around $0.15 to $0.33/min depending on the LLM and voice chosen, so plan for 3x to 6x the advertised rate.
Spec
The gotcha
The advertised "$0.05/min" is just Vapi's orchestration fee, not your bill. STT, LLM, and TTS provider costs plus telephony are passed through on top, so real per-minute cost is typically 3x-6x higher (often $0.15-$0.33/min). HIPAA ($2,000/mo) and zero-data-retention ($1,000/mo) are expensive paid add-ons, and SOC 2/SSO/RBAC require the annual Scale contract.
Decode the real cost →Best for
- You want to build production voice agents (inbound support lines, outbound sales/qualification, appointment booking) with full control over the STT/LLM/TTS stack via an API and SDKs, rather than a closed no-code voice tool that locks you into one set of providers.
