Why I Built This

I wanted to continue vibe coding after bed. I tried ngrok, but it requires registration. I tried Cloudflare Tunnel, but it doesn't provide a usable terminal UI. I tried Termius, but it comes with apps, accounts, and too much setup. I just wanted something simpler: open a browser, get a terminal, start typing.

So I built Porterminal. A mobile-first web terminal with secure tunneling, no registration, no installation on your phone, and a touch-friendly UI optimized for vibe coding with whatever AI app you want.

Features

• One command, instant access - No SSH, no port forwarding, no config files. Cloudflare tunnel + QR code.
• Actually usable on mobile - Virtual modifier keys (Ctrl, Alt, Tab, arrows), swipe gestures, copy/paste that works.
• Multi-tab sessions - Run builds in one tab, tail logs in another. Sessions persist across reconnects.
• Cross-platform - Windows (PowerShell, CMD, WSL), Linux/macOS (Bash, Zsh, Fish). Auto-detects your shells.

Configuration

Create config.yaml in your working directory (optional):

terminal:

  cols: 120
  rows: 30

buttons:
  - label: "git"
    send: "git status\r"

Full config options

server:
  host: "127.0.0.1"
  port: 8000

terminal:
  cols: 120
  rows: 30
  default_shell: powershell

  # Custom shells (auto-detected if not specified)
  shells:
    - id: powershell
      name: PowerShell
      command: powershell.exe
      args: ["-NoLogo"]
    - id: wsl
      name: WSL
      command: wsl.exe

  - label: "git"
    send: "git status\r"
  - label: "ls"

Security

Warning: The URL is the only authentication. Anyone with the link has full terminal access.

Best practices:

• Don't share the URL
• Stop the server when not in use (Ctrl+C)
• Use --no-tunnel for local network only

Built-in protections:

• Environment variables sanitized (API keys, tokens stripped)
• Rate limiting on input
• Cloudflare Access integration for teams
