Vapi

Vapi - Voice AI agents for developers

Vapi is a platform that enables developers and businesses to build, deploy, and scale voice AI agents for both inbound and outbound calls. It emphasizes API-first configurability, interoperability with existing stacks, and enterprise-grade reliability. The platform powers thousands of daily calls across diverse use cases and industries, from customer support to operations, with a focus on reducing engineering effort and time-to-value.

Key value propositions include: high configurability via an API-native approach, broad language support, support for bringing your own models or plugging in self-hosted solutions, tool integration to fetch data and perform actions, governance features like guardrails and automated testing, and enterprise-grade reliability and security.

How It Works

1. Choose your workflow. Start from thousands of pre-made templates or build a custom flow tailored to your use case.
2. Plug it in. Integrate across telephony, websites, or apps using the platform’s flexible integration options.
3. Go live. Deploy to handle millions of calls with scalable, low-latency performance.

Use Cases

• Inbound calls, outbound calls, and automated interactions
• Integration with 40+ apps to automate data retrieval and actions
• Multilingual agent conversations (English, Spanish, Mandarin, and 100+ languages supported)
• Real-time voice-enabled workflows within telephony, websites, and apps

Features

• API-native architecture: Everything exposed as APIs with thousands of configurations and integrations
• Bring your own models: Use your own transcription, LLM, or TTS models; or plug in self-hosted models
• Tool calling: Integrate your APIs as tools to fetch data and perform actions on your server
• A/B testing: Experiment with prompts, voices, and flows to optimize performance
• Automated testing: Design test suites to identify hallucination risks before production
• Real-time, enterprise-grade reliability: 99.9% uptime with forward-deployed engineering support
• Sub-500ms latency: Scales to millions of calls with ultra-low latency interactions
• Data governance and security: SOC2, HIPAA, and PCI-compliant for regulated industries
• Multi-language support: Communicate with users in English, Spanish, Mandarin, and 100+ languages
• Flexible deployment: Deploy via telephony, websites, or in-app integrations
