What it does

Vapi is a developer platform for building voice AI agents that make and receive phone calls or run inside web apps. Each agent combines speech-to-text, a large language model and text-to-speech, with a choice of providers for each part. Vapi runs the call infrastructure, and you configure the voice, conversation flow, telephony and integrations through a dashboard, API, SDKs or CLI.

Features

  • Choice of speech and model providers. You choose the provider and model for speech-to-text, the LLM and text-to-speech, from providers including OpenAI, Anthropic, Google, Gladia, Deepgram and ElevenLabs. Presets bundle a transcriber, model and voice for common use cases. Official source 1 ↗
  • Assistants and Squads. Assistants use one system prompt plus tools and structured outputs. Squads coordinate several specialised assistants and transfer the caller between them while keeping context. Official source 1 ↗
  • Tool and system integration. Agents can call your APIs, databases and existing systems during a conversation. Official source 1 ↗
  • Testing with simulations. Calls can be simulated to test an agent before it reaches customers; testing and simulation are included with every plan. Official source 1 ↗ · Official source 2 ↗
  • Versioning and monitoring. Agent versions can be published and restored. After launch, you can review calls and receive alerts when call quality drops. Official source 1 ↗
  • Config as code and CLI. A CLI covers everything in the dashboard, and assistants, squads, tools and tests can be stored as files in git, reviewed in pull requests and promoted from development to production. Official source 1 ↗
  • Enterprise controls. Enterprise options include SSO, OAuth and role-based access control, contractual uptime and performance guarantees, and SOC 2, HIPAA and PCI compliance. Official source 1 ↗
