Vapi

Vapi is an API-first voice AI platform for building phone agents that handle customer conversations. Developers use it to configure voice, call flow, telephony, integrations, monitoring, and deployment from one place.

Key Highlights

• Build, test, and deploy conversational voice AI agents for phone calls
• Configure voices, conversation flow, telephony, and integrations
• Use orchestration and real-time monitoring to improve agents after launch
• Scale to high-volume call programs with enterprise support options
• Compare retention, support, and governance in eligible Success Packages

What Makes It Different

Vapi is built around developer control rather than a fixed call-center script builder. Its API-first setup lets teams connect voice agents to their own systems, model providers, telephony, and workflows.

Success Packages add operational support and governance at different levels. Retention, concurrency, and support terms should be assessed alongside usage costs when planning a production call program.

Features & Capabilities

Teams configure prompt, voice, conversation flow, telephony, and integrations, then use monitoring to inspect live calls and improve agents after launch.

Supported use cases include customer support, outbound selling, healthcare, marketplace, and staffing. Enterprise features include SSO, OAuth2, RBAC, AI guardrails, compliance options, reserved capacity, and a dedicated account team on eligible Success Packages.

User Ratings and Testimonials

Test representative calls and inspect latency, handoffs, tool use, and error recovery. Usage-only access has peer support and email without an SLA. Support, retention, concurrency, and governance controls depend on the Success Package selected.
