Antigravity Better is a lightweight, zero-dependency toolkit for customizing the AI chat panel in Antigravity - Google's new AI-powered IDE.

We provide a single HTML file that you can drop into your IDE to unlock powerful customizations - without touching any source code or installing extensions.

You can freely customize this HTML file to build your own features. Following our pre-built framework makes modifications incredibly easy - just add your CSS rules and JS logic, and you're good to go!

💡 Philosophy: We build the highway; you drive whatever car you want.

• ✅ Primary Target: Antigravity (Google's AI IDE)
  • v0.2.x: Supports IDE v1.18.3+ (New workbench.html architecture)
  • v0.1.x: Supports older IDE versions(<1.18.3) (Legacy cascade-panel.html architecture)
• ⚠️ Potentially Compatible: Other VS Code-based AI IDEs (Cursor, Windsurf, etc.) may work with modifications, but we cannot guarantee compatibility.

• v0.2.10: Fixes the Undo icon rendering issue in conversations by allowing the required Google resources in the Content Security Policy. The fix proposal came from hanliangwei.
• v0.2.9: Fixes accidental auto-clicks on conversation titles when creating a new conversation by skipping title buttons that carry both title and grow.
• v0.2.8: Fixes the app version string that was still shown as 0.2.2, and aligns documentation version info.
• v0.2.7: Enhances update checks with dual-source fallback (GitHub API + backup API), shows current/remote version comparison, adds a download entry, and introduces an auto-dismiss system tool for corrupted-install warnings.
• v0.2.6: Adds auto-accept rules for diff confirmations and permission prompts, with safer handling for accept all, always allow, and allow this conversation.
• v0.2.5: Improves workbench UI, replaces emoji icons with inline SVG, and refines tab alignment, floating settings button, update-check button style, and close-button hit area.
• v0.2.4: Fixes LaTeX inline formula rendering issue (#23).
• v0.2.3: Adds a deployment tool for workbench.html.
• v0.2.2: Fixes copy button misalignment and auto-accept click issues, and adds max-click limit with reset.
• v0.2.1: Migrates to IDE v1.18.3+ workbench.html architecture with v0.1.7 feature parity.
• v0.1.7: Stable legacy-architecture release (cascade-panel.html).
• v0.1.6: Merges auto-retry capability into auto-accept.
• v0.1.5: Adds LaTeX formula rendering.
• v0.1.4: Adds font-size control and version check.
• v0.1.3: Adds safety rules to block dangerous auto-executed commands.
• v0.1.2: Adds auto-retry mechanism.
• v0.1.1: First core feature set: custom colors, hotkey override, and i18n support.

• Single-file architecture: All CSS/JS/HTML in one file
• Zero build tools: No npm, no bundler - just edit and replace
• Performance-first: Disabled features = zero runtime cost
• Well-documented: Clear code structure with comments
• Extensible: Add your own features following simple patterns

1. Locate the target file

   macOS: /Applications/Antigravity.app/Contents/Resources/app/out/vs/code/electron-browser/workbench/workbench.html
   Windows: [PathToAppFolder]/Antigravity/resources/app/out/vs/code/electron-browser/workbench/workbench.html
   

2. Backup & Replace

   # Navigate to the installation directory
   ## Mac os
   cd /Applications/Antigravity.app/Contents/Resources/app/out/vs/code/electron-browser/workbench/
   ## Windows
   cd [PathToAppFolder]/Antigravity/resources/app/out/vs/code/electron-browser/workbench/
   
   # Backup original
   cp workbench.html workbench.html.bak
   
   # Replace with Antigravity Better
   cp /path/to/antigravity-better/app_root/workbench.html ./

3. Restart Antigravity - Done! 🎉

⚠️ Note: Every time Antigravity updates, it will overwrite the HTML file. You'll need to re-apply this replacement after each update.

If you encounter a "File is damaged and should be moved to the Trash" warning on Mac OS (especially in v1.20.5), follow these steps:

1. Click Cancel to keep the file.
2. Go to System Settings -> Privacy & Security -> Security.
3. You should see a message saying "Antigravity was blocked...". Click Allow Anyway or Open Anyway.
4. Open Antigravity again. When the dialog appears, select Open (you may need to right-click the app and select Open instead of using double-click).
5. This only needs to be done once to grant permission.

Note: We have only tested this on macOS. Other platforms might encounter similar issues; please look for system-specific security permission solutions.

Click the ⚙️ floating button on the right side of your chat panel to open settings.

• Switch between Appearance and Features tabs
• Expand/collapse each feature section
• Toggle language between English/中文

Antigravity Better is designed to be extended:

<style>
  /* 1. Add your CSS - only active when feature class is present */
  #react-app.your-feature .target { color: red; }
</style>

<script>
  // 2. Add your feature config
  const YOUR_CONFIGS = [{ id: 'my-feature', ... }];
  
  // 3. Implement your logic (respecting on/off state)
  function applyYourFeature() {
    if (!currentSettings.yourFeatureEnabled) return;
    // Your code here
  }
</script>
