LiveKit

What is LiveKit?

LiveKit is a comprehensive platform designed for developers to build production-grade real-time communication applications. Built on WebRTC technology, it combines an open-source framework with optional cloud hosting, eliminating the complexity of managing real-time infrastructure. The platform supports voice agents, video conferencing, telephony integration, and physical robotics applications. LiveKit handles critical aspects like low-latency media routing, connection management, and scalability, allowing developers to focus on creating differentiated user experiences. With support for multiple AI model providers and flexible deployment options—whether self-hosted or on LiveKit Cloud—the platform serves startups to enterprise organizations. LiveKit Cloud powers ChatGPT's Advanced Voice Mode and currently processes over 3 billion calls annually.

Key Features

• Voice Agent Framework

  Rapidly build voice agents in Python or Node.js with integrated speech-to-text, language models, and text-to-speech components. Deploy agents that can answer calls, join meetings, or engage in conversations with end-to-end turn detection and multilingual support.

• Real-Time Media Transport

  Low-latency audio and video delivery (20-100ms) using WebRTC with selective forwarding unit (SFU) architecture. Supports adaptive streaming, dynamic quality adjustment, and end-to-end encryption for secure communications.

• Multi-Platform SDKs

  Consistent APIs and SDKs across web, iOS, Android, Flutter, React Native, and server-side languages including Python, Node.js, Go, and Rust. Native support for screen sharing, recording, and data channels.

• Flexible AI Model Integration

  Connect to multiple AI providers including OpenAI, Anthropic, Google, and specialized providers for speech-to-text, language models, and text-to-speech. LiveKit Inference provides direct model access through the platform.

• Scalable Cloud Infrastructure

  Managed cloud service with automatic scaling, global distribution, and predictable usage-based pricing. Alternatively, self-host on your infrastructure with Docker, Kubernetes, or custom deployments for full control and compliance requirements.

• Enterprise-Grade Security

  End-to-end encryption, SOC2 compliance, HIPAA compliance options, JWT-based authentication, and track-level permission controls. Full data residency control for sensitive applications.
