Vapi

Developer-grade voice AI infrastructure for custom phone agents.

What it does

Vapi provides the building blocks for voice AI: speech-to-text, LLM reasoning, and text-to-speech orchestrated over phone calls. It is the choice when off-the-shelf voice agents cannot handle your workflow.

Best use cases

  • Fully custom phone agent logic
  • Voice agents wired into proprietary systems
  • High-volume outbound call campaigns
  • Multi-step phone workflows with API actions

Business outcomes

Voice experiences impossible in no-code tools
Deep integration with your exact stack
Costs that scale with real usage

Who it is best for

Companies with engineering resources — or an agency partner — building differentiated voice systems.

Limitations — the honest part

No tool is perfect. Here is where this one falls short, so you decide with open eyes.

  • Requires developers; not a no-code product
  • You assemble and maintain the stack yourself
  • Multiple usage costs to monitor (Vapi, STT, LLM, TTS, telephony)
  • Time to first production agent is longer
