🚀 Quick Start

💡 Tip: While we recommend starting Antigravity first, the server is now smart enough to wait and automatically connect whenever Antigravity becomes available!

Step 1: Launch Antigravity in Debug Mode

Start Antigravity with the remote debugging port enabled:

Option A: Using Right-Click Context Menu (Recommended)

• Run install_context_menu.bat (Windows) or ./install_context_menu.sh (Linux) and select [1] Install
• Then right-click any project folder → “Open with Antigravity (Debug)” (now with visual icons!)

Option B: Manual Command

antigravity . --remote-debugging-port=9000

Step 2: Open or Start a Chat

• In Antigravity, open an existing chat from the bottom-right panel, OR
• Start a new chat by typing a message

💡 The server needs an active chat session to capture snapshots. Without this, you’ll see “chat container not found” errors.

Step 3: Run the Server

Windows:

Double-click start_ag_phone_connect.bat

macOS / Linux:

chmod +x start_ag_phone_connect.sh   # First time only
./start_ag_phone_connect.sh

The script will:

• Auto-setup a Python Virtual Environment (venv) (Fixes PEP 668 issues on Arch/Linux)
• Verify Node.js and Python dependencies
• Auto-kill any existing server on port 3000
• Wait for Antigravity if it’s not started yet
• Display a QR Code and your Link (e.g., https://192.168.1.5:3000)
• Provide numbered steps for easy connection

Step 4: Connect Your Phone (Local Wi-Fi)

1. Ensure your phone is on the same Wi-Fi network as your PC
2. Open your mobile browser and enter the URL shown in the terminal
3. If using HTTPS: Accept the self-signed certificate warning on first visit

🌍 NEW: Global Remote Access (Web Mode)

Access your Antigravity session from anywhere in the world (Mobile Data, outside Wi-Fi) with secure passcode protection.

Step 1: Choose a Tunnel Provider

You can use ngrok (requires account), Cloudflare Tunnel (requires cloudflared), or Pinggy (free SSH tunnel, no account/install needed).

Option A: ngrok (Default)

1. Get an ngrok Token: Sign up for free at ngrok.com and get your “Authtoken”.
2. Setup: Update your .env file:

   TUNNEL_PROVIDER=ngrok
   NGROK_AUTHTOKEN=your_token_here
   

Option B: Cloudflare Tunnel

1. Install cloudflared: Follow the official guide to install cloudflared on your system.
2. Setup: Update your .env file:

   TUNNEL_PROVIDER=cloudflare
   

Option C: Pinggy Tunnel

1. No Install Required: Pinggy works via SSH and the Python SDK. The launcher will automatically install the pinggy pip package.
2. Setup: Update your .env file:

   TUNNEL_PROVIDER=pinggy
   

   (Optional) You can add PINGGY_TOKEN=your-token for a persistent subdomain if you have a Pinggy account.

Step 2: Configuration

1. Automatic Configuration: Simply run any launcher script. They will detect if .env is missing and automatically create it using .env.example as a template.
2. Manual Setup: Alternatively, copy .env.example to .env manually and update the values:

   copy .env.example .env   # Windows
   cp .env.example .env     # Mac/Linux
   

   Ensure you set a secure password:

   APP_PASSWORD=your_secure_passcode
   

Usage

• Windows: Run start_ag_phone_connect_web.bat
• Mac/Linux: Run ./start_ag_phone_connect_web.sh

The script will launch the server and provide a Public URL (e.g., https://abcd-123.ngrok-free.app).

Two Ways to Connect:

1. Magic Link (Easiest): Scan the Magic QR Code displayed in the terminal. It logs you in automatically!
2. Manual:
   • Open the URL on your phone.
   • Enter your APP_PASSWORD to log in.

💡 Tip: Devices on the same local Wi-Fi still enjoy direct access without needing a password.

🔒 Enabling HTTPS (Recommended)

For a secure connection without the browser warning icon:

Option 1: Command Line

node generate_ssl.js

• Uses OpenSSL if available (includes your IP in certificate)
• Falls back to Node.js crypto if OpenSSL not found
• Creates certificates in ./certs/ directory

Option 2: Web UI

1. Start the server on HTTP
2. Look for the yellow “⚠️ Not Secure” banner
3. Click “Enable HTTPS” button
4. Restart the server when prompted

After Generating:

1. Restart the server - it will automatically detect and use HTTPS.
2. On your phone’s first visit:
   • You’ll see a security warning (normal for self-signed certs).
   • Tap “Advanced” → “Proceed to site”.
   • The warning won’t appear again!

macOS: Adding Right-Click “Quick Action” (Optional)

Since macOS requires Automator for context menu entries, follow these steps manually:

1. Open Automator (Spotlight → type “Automator”).
2. Click File → New and select Quick Action.
3. At the top, set:
   • “Workflow receives current” → folders
   • “in” → Finder
4. In the left sidebar, search for “Run Shell Script” and drag it to the right pane.
5. Set “Shell” to /bin/zsh and “Pass input” to as arguments.
6. Paste this script:

   cd "$1"
   antigravity . --remote-debugging-port=9000
   

7. Save the Quick Action with a name like Open with Antigravity (Debug).
8. Now you can right-click any folder in Finder → Quick Actions → Open with Antigravity (Debug).

🛡️ Shielding & Account Safety

This tool is designed with a “Local-First” security model.

• Bridge Mechanism: It uses the Chrome DevTools Protocol (CDP) to mirror the UI of your already-running desktop session. It never extracts OAuth tokens or interacts with Google/AI-provider APIs directly.
• Natural Traffic: All AI requests are still sent by your official desktop application. To the AI provider, your usage looks identical to normal desktop activity.
• Zero Bans: There have been no reports of account flags or bans. This is a “Wireless Viewport,” not a third-party client that bypasses official security.
