## About the Tool

Vapi is a developer platform for building real-time voice AI agents that can handle phone calls, voice assistants, and conversational workflows. It gives builders infrastructure for connecting speech, language models, telephony, and business logic.

For FutureStack users, Vapi matters because voice agents are becoming a major AI category. Developers and founders are building receptionists, sales callers, support agents, appointment schedulers, and voice interfaces that need low latency and reliable orchestration.

Vapi belongs in this batch as a growing SEO opportunity. Voice agent searches are increasing, and many builders compare Vapi with Retell, Bland AI, ElevenLabs, Hume AI, Cartesia, and custom Twilio stacks.

This listing is best for technical teams building production voice AI products. It helps FutureStack cover the infrastructure layer behind AI calling, conversational agents, and real-time speech applications.
