Antigravity Panel (Unofficial)
[!IMPORTANT]
This is an unofficial independently developed extension. It is not affiliated with, sponsored by, or endorsed by Google or the Antigravity team. It requires the official Antigravity application to be installed on your local computer.
The Antigravity Agent Manager inside VS Code and VSCodium.
This extension does not re-implement Antigravity: it connects to the Antigravity application already installed on your computer and embeds its real user interface (served by the app's local language server) directly into a VS Code panel. This guarantees:
- Identical Aesthetics — It uses the actual Antigravity UI, not a visual clone.
- Model Selector & Thinking — The native options from the app (Gemini 3.5 Pro High/Low, Claude, etc.) remain fully functional.
- Unified Session — Uses the same account, preferences, and chat history as your standalone Antigravity app.
- Workspace Sync — The Open Project button lets you send your active VS Code folder directly to the Antigravity app.
How It Works
The Antigravity desktop app starts a local language server (language_server.exe) that serves the Agent Manager interface over HTTPS on a random local port, using a self-signed certificate trusted by the app's Electron framework. The extension:
- Finds the active Antigravity language server process and its HTTPS port.
- Launches a lightweight local proxy that terminates TLS (accepting the self-signed certificate in Node.js) and serves the UI over plain HTTP on
127.0.0.1.
- Injects the "native bridges" (like
window.nativeStorage, electronNative, and dialog shims) that the UI expects from the Electron preloader. This allows settings to be persisted by the extension, folder pickers to use VS Code APIs, and links to open in your default web browser.
- Embeds the resulting HTTP page in a VS Code webview (available in the sidebar or as an editor tab).
If Antigravity is not running, the panel offers a Launch Antigravity button that boots the app, passes it the current project folder, and connects as soon as the server becomes available.
Usage
- Click the Antigravity icon in the Activity Bar (sidebar).
- Or use the command palette:
Ctrl+Shift+P → Antigravity: Open Agent Manager in a Tab (recommended for a wider layout).
- Antigravity: Open Current Project Folder in Antigravity opens your current workspace inside the Antigravity application.
- The 🚀 Antigravity status bar item shows the connection state (✓ connected / ○ not running).

Installation
code --install-extension antigravity-panel-0.2.13.vsix
codium --install-extension antigravity-panel-0.2.13.vsix
Or from VS Code/VSCodium: Extensions (Ctrl+Shift+X) → "..." Menu → Install from VSIX...
Requirements
- The official Antigravity application installed.
- Windows (auto-detected). macOS/Linux are supported by manually configuring
antigravityPanel.executablePath.
Privacy & Security
