About
Vapi is a developer-first platform for building, testing and deploying AI voice agents. It is one of the most-reviewed voice AI products on Product Hunt and is widely used by developers and agencies building phone agents.
Teams use Vapi to create agents that answer inbound calls, run outbound campaigns, book appointments and qualify leads. Vapi orchestrates speech recognition, language models and voice synthesis from many providers, supports function calling and tool use mid-conversation, and connects to phone systems.
Vapi uses usage-based pricing: a platform fee of $0.05 per minute, plus the cost of the speech, language model, voice and telephony providers you choose. Real-world totals often reach roughly $0.15 to $0.35 per minute depending on the stack, and some compliance features are paid add-ons.
