  2. Development Environment: Build and deploy websites, web applications, and games
  3. Remote Desktop: Access your computing environment from anywhere
  4. Educational Platform: Learn about web development, cloud computing, and distributed systems
  5. Corporate Solution: Deploy internal tools and applications

System Requirements

Before diving into the installation process, ensure your system meets the following requirements:

Minimum Requirements

  • Operating Systems: Linux, macOS, or Windows
  • RAM: 2GB minimum (4GB recommended for optimal performance)
  • Disk Space: 1GB free space for local development
  • Node.js: Version 20 or higher (Version 23+ recommended)
  • npm: Latest stable version
  • Browser: Modern web browser with JavaScript enabled
  • RAM: 8GB or more for heavy usage
  • CPU: Multi-core processor for better performance
  • Storage: SSD for faster file operations
  • Network: Stable internet connection for cloud features

Installation Methods

Puter offers several installation methods to accommodate different use cases and technical preferences. We’ll explore each method in detail.

Method 1: Local Development Setup

This method is ideal for developers who want to modify Puter or contribute to the project.

Step 1: Clone the Repository

# Clone the Puter repository
git clone https://github.com/HeyPuter/puter.git

# Navigate to the project directory
cd puter

Step 2: Install Dependencies

# Install all required npm packages
npm install

This command will download and install all necessary dependencies as defined in the package.json file.

Step 3: Start the Development Server

# Launch Puter in development mode
npm start

After running this command, Puter should automatically launch in your default web browser at http://puter.localhost:4100 (or the next available port).

Troubleshooting Local Development

If the local development setup doesn’t work immediately, consider these common solutions:

Port Conflicts

# Check if port 4100 is already in use
lsof -i :4100

# Kill the process if necessary
kill -9 <PID>

Node.js Version Issues

# Check your Node.js version
node --version

# Update Node.js if needed (using nvm)
nvm install node
nvm use node

Permission Issues

# Fix npm permission issues (Linux/macOS)
sudo chown -R $(whoami) ~/.npm

Method 2: Docker Deployment

Docker provides a containerized environment that ensures consistent behavior across different systems.

Quick Docker Run

For a simple, one-command deployment:

# Create necessary directories and run Puter
mkdir puter && cd puter && \
mkdir -p puter/config puter/data && \
sudo chown -R 1000:1000 puter && \
docker run --rm -p 4100:4100 \
  -v `pwd`/puter/config:/etc/puter \
  -v `pwd`/puter/data:/var/puter \
  ghcr.io/heyputer/puter

This command will:

  1. Create the necessary directory structure
  2. Set appropriate permissions
  3. Mount configuration and data volumes
  4. Start Puter on port 4100

Understanding Docker Volumes

The Docker setup uses two important volumes:

  • Configuration Volume (/etc/puter): Stores Puter’s configuration files
  • Data Volume (/var/puter): Stores user data and files

Method 3: Docker Compose

Docker Compose provides a more structured approach to container orchestration.

Linux/macOS Setup

# Create directory structure
mkdir -p puter/config puter/data

# Set proper permissions
sudo chown -R 1000:1000 puter

# Download docker-compose.yml
wget https://raw.githubusercontent.com/HeyPuter/puter/main/docker-compose.yml

# Start the services
docker compose up

Windows Setup

# Create directories
mkdir -p puter
cd puter
New-Item -Path "puter\config" -ItemType Directory -Force
New-Item -Path "puter\data" -ItemType Directory -Force

# Download docker-compose.yml
Invoke-WebRequest -Uri "https://raw.githubusercontent.com/HeyPuter/puter/main/docker-compose.yml" -OutFile "docker-compose.yml"

# Start the services
docker compose up

Docker Compose Benefits

Using Docker Compose offers several advantages:

  • Reproducible deployments: Consistent environment across different machines
  • Easy updates: Simple command to pull and deploy new versions
  • Configuration management: Centralized configuration through environment variables
  • Service orchestration: Easy to add additional services like databases or reverse proxies

Advanced Configuration

Environment Variables

Puter supports various environment variables for customization:

# .env file example
PUTER_PORT=4100
PUTER_DOMAIN=puter.localhost
PUTER_DEBUG=true
PUTER_DB_PATH=/var/puter/database

Custom Domain Setup

For production deployments, you’ll want to configure a custom domain:

# Update your domain configuration
PUTER_DOMAIN=your-domain.com
PUTER_PORT=80

SSL/TLS Configuration

For secure HTTPS connections:

# Nginx reverse proxy configuration
server {
    listen 443 ssl;
    server_name your-domain.com;
    
    ssl_certificate /path/to/certificate.crt;
    ssl_certificate_key /path/to/private.key;
    
    location / {
        proxy_pass http://localhost:4100;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
    }
}
