How It Works

Section titled “How It Works”

Development Server Proxying

Section titled “Development Server Proxying”

Pacy Devtools automatically:

  1. Detects your development server ports (common frameworks supported)
  2. Proxies traffic through an available port
  3. Injects debugging tools and WebSocket connections
  4. Preserves all original functionality while adding development features

Port Detection

Section titled “Port Detection”

The CLI intelligently detects development servers by:

  • Parsing package.json scripts for port configurations
  • Watching for new services that start up
  • Avoiding conflicts with existing services
