07/13/2025, 12:19 PMYou can definitely write LiveKit tools using Node.js, even if your main application uses the Python server SDK. LiveKit provides comprehensive Node.js support, including:
• Server SDK: Node.js offers server-side APIs comparable to the Python SDK, enabling room management, participant control, and more.
• Node Realtime SDK: Connect as a server-side participant to publish or subscribe to audio, video, and data.
• Agents Framework: A Node.js framework for building programmable, voice-enabled server-side participants, with plugins for OpenAI, multiple TTS/STT providers, and more.
The different SDKs (Python, Node.js, Go, etc.) can be used independently in your ecosystem, as they all interact with the same LiveKit server infrastructure. This means you can mix and match tools in Node.js with a Python backend as needed.
While the Node.js SDK is currently in beta (the Python SDK is considered slightly more mature), it is fully supported for tool development.
If you need specific guidance on which Node.js SDK or plugin to use for your tool, let me know your use case and I can help further.

07/13/2025, 12:22 PMHey there! Let me break down how Python and Node.js can work together seamlessly in LiveKit - it's actually pretty cool and straightforward. Think of it like your tech tools playing nicely in the same sandbox. By joining the same LiveKit room, these frameworks can totally collaborate and share some awesome capabilities. Here's what that looks like:
• Exchange data and media streams in real-time (imagine live, instant communication between your tools!)
• Coordinate actions through LiveKit room events
• Use Remote Procedure Calls (RPCs) and data APIs to swap information between agents super smoothly
The really neat part? You can set up some really smart workflows, like having a Python agent smoothly hand off to a Node.js agent, all happening in the same room. It's like tag-teaming your technical challenges!
Curious about how this might work for your specific project? I'd love to hear more and help you find the perfect communication strategy. Just shoot over the details!
