About LiveKit Agents
LiveKit is known for its real-time audio and video infrastructure, and its Agents framework builds on that to let developers create voice assistants that join calls like another participant. It handles streaming, turn detection and interruptions.
You write the agent in Python or Node, plug in the speech, language and voice models you prefer, and deploy to LiveKit Cloud or your own servers. The same system can power phone calls, web apps and mobile apps.
The framework is open source, and LiveKit Cloud has a free tier with usage-based pricing. It is a favorite among developers who want control over their voice stack.
