About

Used by enterprise clients for use cases like customer support, lead qualification, and appointment scheduling.

Why it made the leaderboard
If you're building a product that needs voice AI — customer support bots, appointment schedulers, inbound call handlers — Vapi removes the hardest parts: real-time telephony plumbing, sub-500ms latency, and enterprise compliance requirements. It's the difference between spending months on infrastructure and shipping a working voice agent in an afternoon.
