Missing feature in Sandbox? Unable to deploy Next.js Starter App as per documentation

Getting Started

Hi everyone,

My team is currently building an AI Digital Twin and we are using the LiveKit Agent Starter React/Next.js template for our frontend.

We are running into a blocker regarding deployment. According to the LiveKit documentation, it states that we should be able to deploy our starter app directly to the LiveKit Sandbox and obtain a web embed link to use on our site. However, when we access the LiveKit Cloud Sandbox, we cannot find any option, interface, or button to upload, host, or deploy our custom starter app code.

Could the team or community clarify:

  1. Has this frontend deployment feature been moved to a different section of the LiveKit Cloud dashboard?

  2. Is there a specific CLI step we are missing to push our code to the Sandbox?

  3. Or is the Sandbox strictly for testing the agent backend, requiring us to host the Next.js frontend independently on our own infrastructure?

Any guidance on how to get this embed link generated from the Sandbox would be greatly appreciated!

The Sandbox does not host or deploy your custom Next.js frontend code.

Per the Sandbox documentation, Sandboxes provide hosted components for rapid prototyping and can run templates, but some templates (including the Next.js Voice Agent) require you to run code locally. The Sandbox primarily handles backend/token prototyping and sharable demo environments — it is not a general-purpose frontend hosting platform.

The React starter app is designed to be cloned and deployed on your own infrastructure (e.g., Vercel, Netlify, or your own server). There is no dashboard upload feature for custom Next.js apps.
