What is Prime Tunnel?

Prime Tunnel creates secure, public URLs for services running on your local machine. You start a local server, create a tunnel, and get an HTTPS URL that anyone can access. Common use cases:
  • Expose a local development server to the internet
  • Receive webhooks from external services during development
  • Share a work-in-progress app with teammates
Hosted evaluations can use Prime Tunnel too. Launch the run with --allow-tunnel-access, then create the tunnel from inside the hosted sandbox using the same API or CLI flow described here. The flag only grants tunnel permissions to the temporary PRIME_API_KEY. See Hosted Evaluations.

​
Complete Example

Here’s a full working example: start a local HTTP server and expose it to the internet. 1. Start a local server 
# Create a simple HTML file
echo '<h1>Hello from Prime Tunnel!</h1>' > index.html

# Start Python's built-in HTTP server on port 8000
python -m http.server 8000
2. Create a tunnel (in another terminal) 
import asyncio
from prime_tunnel import Tunnel

async def main():
    tunnel = Tunnel(local_port=8000)
    await tunnel.start()

    print(f"Public URL: {tunnel.url}")
    print("Press Ctrl+C to stop")

    # Keep running until interrupted
    try:
        while True:
            await asyncio.sleep(1)
    except KeyboardInterrupt:
        pass
    finally:
        await tunnel.stop()

asyncio.run(main())
3. Access your server Open the printed URL (e.g., https://t-0-abc123def456.tunnel.pinfra.io) in any browser. Your local server is now accessible from anywhere.

​
Context Manager

For automatic cleanup, use the async context manager: 
async with Tunnel(local_port=8000) as tunnel:
    print(f"URL: {tunnel.url}")
    # Tunnel is active here
# Tunnel automatically stopped

​
Tunnel Properties

tunnel = Tunnel(local_port=8000)
await tunnel.start()

tunnel.tunnel_id  # "t-0-abc123def456"
tunnel.url        # "https://t-0-abc123def456.tunnel.pinfra.io"

​
CLI Commands

# Start a tunnel
prime tunnel start --port 8000

# List active tunnels
prime tunnel list

# Stop a tunnel
prime tunnel stop t-0-abc123def456
