Cloudflare Tunnel - Share Your localhost Instantly

Expose your local development server to the internet via Cloudflare Quick Tunnel.

Steps

1. Check if cloudflared is installed. If not, install it:

   • macOS: brew install cloudflared
   • Linux: Download from https://developers.cloudflare.com/cloudflare-one/connections/connect-networks/downloads/

2. Detect which port the app is running on automatically (check running processes, recent terminal output, config files like package.json scripts, docker-compose.yml, etc.). Only ask the user if you genuinely can't determine it.

3. Start the tunnel:

   cloudflared tunnel --url http://localhost:${PORT}

4. Extract the generated public URL from the cloudflared output (it will be a *.trycloudflare.com URL).

5. Present the URL to the user clearly:

   Your app is now live at: https://xxxxx.trycloudflare.com
   
   Share this URL with anyone -- it works on any device, any network.
   

6. Print a celebrative ASCII art banner with the public URL prominently displayed in the center. Make it feel like a "launch moment" -- something the user will want to screenshot and share. Example vibe:

   ╔══════════════════════════════════════════════════════╗
   ║                                                      ║
   ║   🚀  YOUR APP IS LIVE ON THE INTERNET  🚀            ║
   ║                                                      ║
   ║   https://xxxxx.trycloudflare.com                    ║
   ║                                                      ║
   ║   Share this URL with anyone, anywhere.              ║
   ║                                                      ║
   ╚══════════════════════════════════════════════════════╝
   

7. Remind the user:

   • The tunnel stays alive as long as this terminal is open
   • The URL changes if you restart the tunnel
   • For a permanent setup, see Part 2 of Ship It Free

Notes

• No Cloudflare account needed for Quick Tunnels
• HTTPS is automatic -- no certificate setup
• Works behind firewalls and NAT
• 200 concurrent request limit (fine for demos and feedback)
