An open-source framework for building real-time voice and video AI agents, built on LiveKit's WebRTC infrastructure for low-latency conversational applications.
Features
Real-time voice and video agent framework
Built on production-grade WebRTC infrastructure
Low-latency conversational pipeline
Support for speech-to-text and text-to-speech integration
Turn-taking and interruption handling
Scalable infrastructure for production deployment
Open-source SDK with hosted infrastructure option
Multi-participant room support
Pros and Cons
Pros
Built on mature, production-grade WebRTC infrastructure rather than experimental tooling
Specifically designed to handle the tricky parts of real-time voice interaction, like interruption handling
Scales to production traffic, not just prototypes
Open-source SDK gives flexibility alongside a hosted infrastructure option
Cons
Real-time voice/video application development has inherent complexity beyond simpler text-based agents
Requires understanding of WebRTC and real-time infrastructure concepts
Best suited to teams building dedicated voice/video products rather than simple add-on features
