What does LiveKit do?

LiveKit is an open source framework and developer platform for building voice, video, and physical AI agents. It gives you everything you need to develop, test, deploy, scale, and monitor real-time AI agents in production. Whether you want a voice assistant that handles customer calls, a video agent that can see and respond, or a robot that interacts with people, LiveKit provides the building blocks to make it happen.

The platform offers simple APIs to integrate speech-to-text, large language models, and text-to-speech. You configure your agent by choosing providers like Deepgram for STT, OpenAI for LLM, and Cartesia for TTS. LiveKit Cloud handles scaling and low-latency global infrastructure. It also includes telephony integration, so your agent can make and receive phone calls. Every agent session comes with full-stack observability for debugging and monitoring.

This tool is best for developers and teams building AI agents for customer support, sales, telehealth, or any scenario requiring real-time voice or video interaction. The open source framework lets you iterate locally, and when ready, you deploy to LiveKit Cloud for production. Customers range from startups to enterprises like OpenAI and Coursera, powering billions of calls annually.
