Overview

LiveKit is an open source framework and developer platform for building voice, video, and physical AI agents. It is positioned for teams that want to create agent experiences in code, deploy them to cloud infrastructure, and observe behavior in production.

The product combines SDKs, cloud deployment, telephony support, and realtime observability in one platform. The source highlights Python and TypeScript agent development, global infrastructure, and support for agent sessions, routing, scaling, and telemetry across live conversations.

Core capabilities

Code-first agent development

Build agents with LiveKit's open source SDKs in Python or TypeScript, then write the agent logic directly in code.

Cloud deployment and scaling

Deploy agents to LiveKit Cloud so the runtime infrastructure, routing, and autoscaling are handled by the platform.

Production observability

Monitor conversations in production with realtime observability and session metrics, including telemetry for agent sessions.

Inference gateway for voice workflows

Use the platform's model and speech stack to connect LLM, STT, and TTS providers through the agent workflow.

Multichannel voice delivery

Connect agents to web, mobile, and phone experiences, including telephony and SIP-based workflows.

Build, test, and ship lifecycle support

Test and iterate against real scenarios before shipping, with tooling for agent backend, frontend, and testing workflows.

Common use cases

Production voice agents
Create a voice assistant in Python or TypeScript, connect it to STT, LLM, and TTS providers, and run the agent in a production workflow.
Web and mobile conversational apps
Build agent experiences that run in a browser or mobile app, where the user speaks and the agent responds in realtime.
Telephony-enabled assistants
Add phone-call workflows to an agent so it can place or receive calls through telephony integrations.
Managed production deployment
Deploy agents on cloud infrastructure with routing and autoscaling handled by LiveKit Cloud for teams that do not want to manage runtime operations.
Operational observability
Track live sessions and conversation behavior in production so teams can inspect agent performance after launch.

Pros and Cons

Pros

Open source SDKs let teams build agent logic directly in code.
The platform supports deploying and scaling agents on LiveKit Cloud.
Realtime observability makes production conversations easier to monitor.
The source supports both web/mobile and telephony-style voice experiences.
Pricing includes a free start option plus paid tiers for growing teams.

Cons

The source is light on a public integration catalog, so specific third-party services are only partially documented here.
Pricing is usage-oriented and plan details can require reading multiple pages to understand the full cost structure.

FAQ

How do you build and deploy agents with LiveKit?

LiveKit is built to let you build agents in Python or TypeScript, then deploy them to LiveKit Cloud and observe conversations in production.

What kinds of agents does LiveKit support?

The source describes LiveKit as a platform for voice AI, video AI, and physical AI agents, with agent infrastructure and realtime observability.

Does LiveKit have free and paid plans?

The pricing page shows a free Start for free option, paid Build, Ship, and Scale plans, and an Enterprise option that requires contacting sales.

Is LiveKit aimed at developers or non-technical users?

The platform emphasizes open source SDKs, cloud deployment, telephony, and observability rather than a no-code workflow.

What integrations are documented in the source?

The source does not list a fixed feature-by-feature integration catalog, but it does mention model integrations, telephony, SIP, and deployment on LiveKit Cloud.
