How to setup Cloudflare tunnel for remote file viewing?

[0xMag1ci4n]

I'm running OpenACP on a remote server and want to view code files from my phone. How do I set up Cloudflare tunnel to expose the file viewer?

OpenACP has built-in tunneling to expose local ports to the internet and view files remotely via Monaco Editor.

Configure tunnel in ~/.openacp/config.json:

{
  "tunnel": {
    "enabled": true,
    "port": 3100,
    "provider": "cloudflare",
    "maxUserTunnels": 5,
    "storeTtlMinutes": 60,
    "auth": {
      "enabled": false
    }
  }
}

• provider: Choose cloudflare (default), ngrok, bore, or tailscale
• port: Local port to expose (default: 3100)
• maxUserTunnels: Maximum tunnels per user (default: 5)
• storeTtlMinutes: How long to keep tunnel info (default: 60 minutes)

CLI commands:

openacp tunnel add 3100              # Create tunnel on port 3100
openacp tunnel add 8080 --label dev  # Create tunnel with label
openacp tunnel list                  # List active tunnels
openacp tunnel stop 3100             # Stop tunnel

With tunneling enabled, you get a file viewer with Monaco Editor — syntax highlighting, diffs, and markdown preview from your phone.
