LiveKit is an open-source, full-stack platform for building voice, video, and physical AI agents. It provides a real-time infrastructure layer built on WebRTC, spanning 19+ global regions with sub-100ms latency, and handles 3B+ calls annually. Developers access a multi-provider inference gateway supporting LLMs (OpenAI, Google Gemini, DeepSeek, xAI Grok), STT (Deepgram, AssemblyAI, Speechmatics), and TTS (Cartesia, Fish Audio) — all through a unified API. The platform includes native SIP/telephony integration (via Twilio and SIP trunking), full-stack observability, and an agent framework that is self-hostable or available as a managed cloud service. LiveKit is GDPR, SOC 2 Type 2, and HIPAA compliant. The project has 14,500+ GitHub stars.
