VSCode Window Resizer (OS-level)

Resizes the main VS Code window to a specific size using OS tools.

Now supports VS Code forks such as Google Antigravity via an optional opt-in setting.

✨ New: Antigravity Opt-In Support

This extension can now run in Google Antigravity and other VS Code--compatible editors.

By default, the extension automatically detects the host editor using:

vscode.env.appName

If automatic detection fails (for example, due to a custom build or window title differences), you can manually opt-in.

Enable Antigravity manually

Add this setting:

{
  "windowResizer.appHint": "Antigravity"
}

This helps the extension match the correct window process/title when resizing.

⚠️ Important
The extension must run on the UI/local side.
It will not work when installed only inside WSL/SSH remote environments.

Multi-Editor Compatibility

The extension works with:

• Google Antigravity
• Most VS Code forks running on Electron

Window detection is based on:

• Process name
• Window title
• Electron window class
• Optional appHint override

Limitations

VS Code's extension API does not expose window sizing; this extension shells out to OS utilities.

Fullscreen/maximized windows are restored before resizing.

On Linux:

• Only supported under X11
• Not supported under Wayland by default

In Remote environments (WSL/SSH):

• The extension must be installed locally (UI side)
• It cannot resize a window running on a different host
