ptn 0.4.2

Web-based terminal accessible from phone via Cloudflare Tunnel

1. uvx ptn
2. Scan the QR
3. Access your terminal from your phone

Why

I wanted to vibe code from bed.

ngrok requires registration and the free tier sucks. Cloudflare Quick Tunnel works great but is hard to use directly on the phone. Termius requires complicated setup: port forwarding, firewall rules, key management... Tried Claude Code web, but it can't access my local hardware and environment. Also tried Happy, but it's too bulky and updates lag behind.

So I built something simpler: run a command, scan a QR, start typing.

Features

• One command, instant access - No SSH, no port forwarding, no config files. Cloudflare tunnel + QR code.
• Actually usable on mobile - Touch-optimized with momentum scrolling, pinch-to-zoom, swipe gestures, and modifier keys (Ctrl, Alt).
• Full terminal apps - vim, htop, less, tmux all work correctly with proper alt-screen buffer handling.
• Persistent multi-tab sessions - Sessions survive disconnects. Close the browser, switch networks, reconnect from another device—your shell and running processes are still there. Multiple devices can view the same session simultaneously.
• Cross-platform - Windows (PowerShell, CMD, WSL), Linux/macOS (Bash, Zsh, Fish, Nushell, and any shell via $SHELL). Auto-detects your shells.

Configuration

Run ptn --init to create a starter config. It auto-discovers project scripts from package.json, pyproject.toml, or Makefile and adds them as buttons:

ptn -i
# Created: .ptn/ptn.yaml
# Discovered 3 project script(s): build, dev, test

Or create ptn.yaml manually:

# Terminal settings
terminal:
  default_shell: nu              # Default shell ID
  shells:                        # Custom shell definitions
    - id: nu
      name: Nushell
      command: nu
      args: []

# Custom buttons (appear in toolbar)
# row: 1 = default row, 2+ = additional rows
buttons:
  - label: "claude"
    send:
      - "claude"
      - 100        # delay in ms
      - "\r"
  - label: "build"
    send: "npm run build\r"
    row: 2         # second button row

# Update checker settings
update:
  notify_on_startup: true   # Show update notification
  check_interval: 86400     # Seconds between checks (default: 24h)

# Security settings
security:
  require_password: true    # Always prompt for password at startup
  max_auth_attempts: 5      # Max failed attempts before disconnect

Config is searched in order: $PORTERMINAL_CONFIG_PATH, ./ptn.yaml, ./.ptn/ptn.yaml, ~/.ptn/ptn.yaml.

Security

Use password if your screen can be exposed to others:

ptn -p                 # Prompt for password this session
ptn -dp                # Enable password by default (toggle)

Password is per-session (never saved to disk). See docs/security.md for details.

Troubleshooting

Connection fails? Cloudflare tunnel sometimes blocks connections. Restart the server (Ctrl+C, then ptn) to get a fresh tunnel URL.

Shell not detected? Set your $SHELL environment variable or configure shells in ptn.yaml.
