LiveKit

LiveKit is an open-source platform and global edge network for building real-time voice, video, and physical AI applications. Born as a WebRTC media server for livestreaming and conferencing, it has grown into the infrastructure layer that lets AI agents see, hear, and speak with sub-100ms latency. Its technology powers ChatGPT's Advanced Voice Mode and is used by developers at OpenAI, xAI, Salesforce, Tesla, and Spotify, collectively facilitating billions of real-time calls each year.
