Vapi is the developer platform for voice AI agents — build, deploy, and scale phone agents with usage-based pricing and bring-your-own model keys.
Vapi is a developer voice AI platform for production phone agents. Usage-based at $0.05/min plus model costs (free with bring-your-own keys), SMS at $0.005/msg, HIPAA $2k/mo add-on, Zero Data Retention $1k/mo. Scale tier with SOC 2, HIPAA, PCI, SSO, RBAC, and committed volume.
Vapi stands out as the most technically sophisticated voice AI platform for developer teams who need granular control over conversation pipelines. The modular architecture and real-time function calling capabilities enable genuinely useful voice agents that take business actions. However, the developer-heavy setup and potentially high per-minute costs make it less suitable for non-technical teams or cost-sensitive use cases. Choose Vapi when voice quality and customization matter more than ease of use.
