Product Overview
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.
