Remote-Controlling Desktop AI From Your Phone via CDP

What it does Antigravity Phone Connect is a mobile dashboard for the Antigravity AI desktop app. It uses the Chrome DevTools Protocol to scrape snapshots of your local chat window and relays them to a phone-optimized web UI, letting you read, scroll, send messages, and click action buttons remotely. The server sits between your desktop browser and your phone, offering local LAN access plus optional global tunneling through ngrok, Cloudflare, or Pinggy.

The interesting bit Instead of reverse-engineering Antigravity’s internal API or extracting OAuth tokens, it treats the desktop app as a black-box browser and remotely drives the DOM like a puppeteer. That design choice means the AI provider sees entirely normal desktop traffic, which the project claims has kept users free of account flags.

Key highlights

• Sub-100ms desktop snapshots via CDP with 1-second polling sync to mobile
• Full remote control: send messages, switch models/modes, scroll, and tap action buttons like “Allow” or “Review Changes”
• “Nuclear Cleanup” aggressively strips desktop-only UI clutter for a native-feeling mobile view
• Self-hosted with HTTPS, signed httpOnly cookies, and passcode-protected tunnel access
• Local images and SVGs are Base64-encoded so they render on mobile without exposing vscode-file:// paths

Caveats

• Antigravity must be running in debug mode with --remote-debugging-port=9000; without an active chat session the server throws “chat container not found” errors
• First-time mobile visitors will hit browser warnings for the self-signed HTTPS certificate
• macOS users must manually build an Automator Quick Action if they want the right-click context menu integration

Verdict Worth a look if you live in Antigravity and want to approve AI-generated changes from your couch. Skip it if you don’t use Antigravity or if the idea of running your IDE with a remote debugging port open makes you nervous.
