🧩 What is this project?

Rahoot is a straightforward and open-source clone of the Kahoot! platform, allowing users to host it on their own server for smaller events.

⚠️ This project is still under development, please report any bugs or suggestions in the issues

⚙️ Prerequisites

Choose one of the following deployment methods:

Without Docker

• Node.js : version 20 or higher
• PNPM : Learn more about here

With Docker

• Docker and Docker Compose

📖 Getting Started

Choose your deployment method:

🐳 Using Docker (Recommended)

Using Docker Compose (recommended): You can find the docker compose configuration in the repository: docker-compose.yml

docker compose up -d

Or using Docker directly:

docker run -d \
  -p 3000:3000 \
  -p 3001:3001 \
  -v ./config:/app/config \
  -e WEB_ORIGIN=http://localhost:3000 \
  -e SOCKET_URL=http://localhost:3001 \
  ralex91/rahoot:latest

Configuration Volume: The -v ./config:/app/config option mounts a local config folder to persist your game settings and quizzes. This allows you to:

• Edit your configuration files directly on your host machine
• Keep your settings when updating the container
• Easily backup your quizzes and game configuration

The folder will be created automatically on first run with an example quiz to get you started.

The application will be available at:

• Web Interface: http://localhost:3000
• WebSocket Server: ws://localhost:3001

⚙️ Configuration

The configuration is split into two main parts:

1. Game Configuration (config/game.json)

Main game settings:

  "managerPassword": "PASSWORD",
  "music": true
}

Options:

• managerPassword: The master password for accessing the manager interface
• music: Enable/disable game music

2. Quiz Configuration (config/quizz/*.json)

Create your quiz files in the config/quizz/ directory. You can have multiple quiz files and select which one to use when starting a game.

Example quiz configuration (config/quizz/example.json):

    {
      "question": "What is the correct answer?",
      "answers": ["No", "Yes", "No", "No"],
      "image": "https://images.unsplash.com/....",
      "media": { "type": "audio", "url": "https://example.com/song.mp3" },

      "cooldown": 5,
      "time": 15
    }
  ]
}
