# Llama Stack UI

The Llama Stack UI is a web-based interface for interacting with Llama Stack servers. Built with Next.js and React, it provides a visual way to work with agents, manage resources, and view logs.

## Features

- **Logs & Monitoring**: View chat completions, agent responses, and vector store activity
- **Vector Stores**: Create and manage vector databases for RAG (Retrieval-Augmented Generation) workflows
- **Prompt Management**: Create and manage reusable prompts

## Prerequisites

You need a running Llama Stack server. The UI is a client that connects to the Llama Stack backend.

If you don't have a Llama Stack server running yet, see the [Starting Llama Stack Server](../getting_started/starting_llama_stack_server.mdx) guide.

## Running the UI

### Option 1: Using npx (Recommended for Quick Start)

The fastest way to get started is using `npx`:

```bash
npx llama-stack-ui
```

This will start the UI server on `http://localhost:8322` (default port).

### Option 2: Using Docker

Run the UI in a container:

```bash
docker run -p 8322:8322 llamastack/ui
```

Access the UI at `http://localhost:8322`.

## Environment Variables

The UI can be configured using the following environment variables:

| Variable | Description | Default |
|----------|-------------|---------|
| `LLAMA_STACK_BACKEND_URL` | URL of your Llama Stack server | `http://localhost:8321` |
| `LLAMA_STACK_UI_PORT` | Port for the UI server | `8322` |

If the Llama Stack server is running with authentication enabled, you can configure the UI to use it by setting the following environment variables:

| Variable | Description | Default |
|----------|-------------|---------|
| `NEXTAUTH_URL` | NextAuth URL for authentication | `http://localhost:8322` |
| `GITHUB_CLIENT_ID` | GitHub OAuth client ID (optional, for authentication) | - |
| `GITHUB_CLIENT_SECRET` | GitHub OAuth client secret (optional, for authentication) | - |

### Setting Environment Variables

#### For npx:

```bash
LLAMA_STACK_BACKEND_URL=http://localhost:8321 \
LLAMA_STACK_UI_PORT=8080 \
npx llama-stack-ui
```

#### For Docker:

```bash
docker run -p 8080:8080 \
  -e LLAMA_STACK_BACKEND_URL=http://localhost:8321 \
  -e LLAMA_STACK_UI_PORT=8080 \
  llamastack/ui
```

## Using the UI

### Managing Resources

- **Vector Stores**: Create vector databases for RAG workflows, view stored documents and embeddings
- **Prompts**: Create and manage reusable prompt templates
- **Chat Completions**: View history of chat interactions
- **Responses**: Browse detailed agent responses and tool calls

## Development

If you want to run the UI from source for development:

```bash
# From the project root
cd src/llama_stack_ui

# Install dependencies
npm install

# Set environment variables
export LLAMA_STACK_BACKEND_URL=http://localhost:8321

# Start the development server
npm run dev
```

The development server will start on `http://localhost:8322` with hot reloading enabled.
