Getting Started

Prerequisites

• NeMo Agent Toolkit installed and configured
• Git
• Node.js (v20 or higher)
• npm or Docker

Installation

Clone the repository:

git clone git@github.com:NVIDIA/NeMo-Agent-Toolkit-UI.git
cd NeMo-Agent-Toolkit-UI

Install dependencies:

npm ci

Running the Application

Local Development

npm run dev

The application will be available at the proxy port configured in your `PORT` environment variable (default: `http://localhost:3000`)

**Important:** Check terminal startup logs for the actual web application URL (e.g., `http://localhost:3000`). If the configured port conflicts, an alternate port will be assigned. Do not access the internal Next.js port directly (default: 3099) as API and WebSocket communication will fail.

Docker Deployment

# Build the Docker image
docker build -t nemo-agent-toolkit-ui .

# Run the container with environment variables from .env
# Ensure the .env file is present before running this command.
# Skip --env-file .env if no o
