What Is Vapi AI? How It Works + Best Alternative for Sales

What is Vapi

Vapi is a developer platform for building AI voice agents from scratch using APIs and SDKs. It's powerful infrastructure for engineering teams - but for sales teams, agencies, and service businesses that need a working AI dialer today, RizzDial is the no-code alternative built on the same class of voice technology.

How Vapi works

Vapi (vapi.ai) provides voice agent infrastructure: speech-to-text, LLM orchestration, and text-to-speech wired together over a real-time call layer. Developers integrate via REST APIs and SDKs to build custom voice agents - bring-your-own LLM, bring-your-own telephony, bring-your-own logic. It typically takes 2-6 weeks of engineering time to ship a production agent.

Who Vapi is for

Engineering teams building custom voice products.

AI startups building voice-first applications.

Enterprises with complex, bespoke voice workflows and a dev team to maintain them.
