What are LiveKit and Vapi?
LiveKit is a complete real-time communication platform that uses WebRTC technology to enable low-latency audio, video, and data exchange between users and AI agents. Unlike traditional communication tools, LiveKit is built specifically for developers who want to create custom real-time experiences.
The platform consists of several parts: the open-source LiveKit server that handles media routing, client SDKs for all major platforms, and LiveKit Cloud for managed hosting. It uses a Selective Forwarding Unit (SFU) architecture, which means it can efficiently handle many participants without heavy server processing.
LiveKit is especially strong for AI applications. It can connect voice agents to phone systems, enable real-time transcription, and support multimodal AI that can see and hear simultaneously. Whether you want to build a simple video chat or a complex AI assistant, LiveKit provides the foundation you need.
Vapi is a developer-focused platform that provides the infrastructure needed to build voice AI agents for phone interactions. Instead of spending months building voice technology from scratch, developers can use Vapi's APIs to create voice agents in minutes.
The platform works by combining several AI technologies: speech recognition to understand what people say, language models to generate smart responses, and text-to-speech to reply with natural voices. What makes Vapi special is its speed - conversations happen in real-time with responses under 500 milliseconds, making interactions feel natural.
Developers can choose from multiple AI providers like OpenAI, Google, and ElevenLabs, or bring their own models. The platform supports over 100 languages and includes security features that meet healthcare and financial industry standards. It's designed to scale from small projects to millions of calls.
