Developer platform for building voice AI agents
Reviewed by the the30top research team 路 Last reviewed 2026-10-27
Overview
Vapi gives developers the building blocks for voice agents: orchestration, telephony and a catalog of speech and language model providers. It is built for teams that want control over every layer, and it has raised $72M in total funding. The limitation is cost clarity, because the $0.05 per minute hosting fee is only one part of the bill and provider charges are added on top. HIPAA handling is a $2,000 per month add-on.
Our verdict
Vapi is the flexible choice for engineers who want to assemble their own voice stack. Non-technical teams and anyone who wants one predictable per-minute price will find it harder to cost and run.
Best for
Developer teams building custom voice agents or embedding calling into their own product.
Avoid if
You want a no-code tool a sales team can configure alone.
