LiveKit

LiveKit is an open-source real-time communication framework and developer platform for building voice AI agents, video applications, and robotics interfaces, powering billions of calls annually in production. The open-source agents framework has accumulated over 11,000 GitHub stars and provides turn detection, interruption handling, and automatic speech recognition through Deepgram Nova-3, LLM reasoning through GPT and Claude models, and text-to-speech through Cartesia Sonic. OpenAI built ChatGPT Advanced Voice Mode on the platform, serving millions of daily users worldwide. Enterprise customers include Tesla for in-vehicle voice experiences, Oracle for enterprise communications, Spotify for collaborative audio, Whatnot for live commerce streaming, Decagon for AI-powered customer support, and Podium for voice agents. The WebRTC-based media server supports millions of concurrent sessions across 19 global regions with sub-second end-to-end latency and 100-percent uptime. Developers deploy agents in Python or Node.js, define multi-language turn detection models, and expose tools to AI agents via Model Context Protocol for function calling. The platform is GDPR, SOC 2 Type II, and HIPAA compliant, serving healthcare and regulated industries. Founded by CEO Russ DSa, the company is headquartered in San Francisco. The free tier includes 1,000 agent session minutes monthly. The Turn Detector v1 model introduced in 2026 solves end-of-turn detection for natural conversational flow.
