How It Works

Dvaar creates a secure WebSocket tunnel between your local machine and our edge servers. When traffic hits your public URL (e.g., https://myapp.dvaar.app), it's forwarded through the tunnel to your local server.

Internet → dvaar.app → WebSocket Tunnel → localhost:3000

Beautiful Request Logging

Dvaar shows real-time, color-coded request logs in your terminal:
