LiveKit is a developer platform that provides infrastructure for creating AI agents capable of real time interaction. It combines an open source framework with a managed cloud service to handle media transport and scaling.
The platform is designed for developers building multimodal AI, supporting the development lifecycle from coding and testing to production deployment. It provides tools for the inference of language, speech-to-text (STT), and text-to-speech (TTS) models.
Buyers can host agents that interact via web, mobile, or phone systems. The cloud version manages the runtime infrastructure, including routing and autoscaling, while the open source version supports self-hosting.
Prospective users should confirm their requirements for concurrency and session minutes, as different plan tiers provide different limits on agent deployments and concurrent sessions.
Key Features
Real time Inference
Supports routing for LLM, STT, and TTS models.
Telephony SIP Integration
Supports connecting AI agents to phone systems for inbound and outbound calling.
Agent Observability
Provides tools to review session recordings, transcripts, and trace spans to monitor performance.
Global Cloud Network
A distributed mesh of media servers designed for voice and video transport.
Conversational Intelligence
Includes models for interruption handling and end-of-turn detection.
Open Source SDKs
Provides server-side SDKs in Python and TypeScript for custom agent logic.
Use Cases
Voice AI Agent Deployment
Building and hosting AI agents that interact with users via voice in real time.
Telephony Integration
Connecting AI agents to phone numbers for automated call handling using SIP support.
Agent Performance Monitoring
Using observability tools to inspect conversation logs and latency to adjust agent behavior.
Multimodal Interface Development
Creating agent interfaces that support voice and video across web, iOS, and Android platforms.
Best For
- Software companies
- Enterprise developers
- AI engineering teams
Pricing
Pricing follows a freemium model with a free Build plan. Paid options include the Ship plan starting at $50/mo and the Scale plan starting at $500/mo, with custom Enterprise pricing available.
FAQ
Does LiveKit have a free version?
