Antigravity Link

What is Antigravity Link?

Antigravity Link is an open-source extension for the Antigravity IDE that lets you step away from your desk without losing track of an AI session. Scanning a QR code turns your phone into a live mirror of the active chat in a mobile browser. From there you can follow replies while they stream in, send new messages, halt generation, upload files, dictate by voice and move between several Antigravity windows. The extension runs a local server protected by a token, finds Antigravity through the Chrome DevTools Protocol and simulates input in your own editor, so it does not patch Antigravity files or intercept its network traffic. For automation it also provides a local HTTP API with endpoints such as /snapshot, /send and /stop, plus an MCP server with nine tools so other agents can drive a session. The mobile interface is available in 16 languages. It is free under the MIT license and works on your local network only unless you tunnel it yourself.

Use cases

• Monitor an Antigravity session from your phone
• Send a message to a running AI chat remotely
• Stop AI generation while away from the desk
• Upload files into an Antigravity chat
• Dictate prompts by voice from mobile
• Automate Antigravity through an API or MCP

Who it's for

Why use Antigravity Link

• A dedicated stop control lets you cancel a runaway generation quickly from mobile.
• Agents and scripts can use the HTTP API or MCP tools to read and drive a session.
• All traffic stays on your machine and local network, with no third-party service in between.

How to get started with Antigravity Link

1. Install Antigravity Link from the Antigravity extensions marketplace or Open VSX.
2. Launch Antigravity with --remote-debugging-port=9000 so the extension can find the session.
3. Run Antigravity Link: Start Server, then Antigravity Link: Show QR Code from the command palette.
4. Scan the QR code with a phone on the same Wi-Fi network and accept the self-signed certificate warning.
5. Read, message, upload or stop generation from the mobile page, or connect an agent to the API or MCP server.

Antigravity Link limitations

• Antigravity must be launched with the --remote-debugging-port flag, or sessions are not discoverable
• The server is LAN-only; remote access needs a tunnel such as ngrok or wireguard
• The phone shows a self-signed certificate warning that you must accept
• Voice input needs HTTPS for microphone permission
