Google Antigravity

Google Antigravity is Google's agent-first IDE. The site is signed by Google DeepMind. This page used to embed a broken YouTube URL and to state a $2.4B Windsurf-team acquisition as fact. We dropped the acquisition number. The video is now a real id.

Compare Kiro and Cursor if you want a generally available paid IDE instead of a preview.

Key Features

• Agent-first IDE: Agents can use the editor, terminal, and a browser from the product copy.
• Model list moves: Do not freeze Gemini 3 Pro / Claude Sonnet 4.5 / Opus 4.5 / GPT-OSS-120B as the forever catalog. Confirm the in-app picker.
• Not ADK: Google ADK is the SDK. This is the IDE.

Use Cases

• People who want a Google-branded agent IDE and will accept preview limits.
• Gemini-first teams that do not want to adopt Cursor.
• Readers who landed here from the Gemini 3 launch.

Limitation: preview terms change. The Windsurf-team story is unverified on the pages we used.

Pricing

Getting Started

1. Open antigravity.google.
2. Download for your OS from that page.
3. Sign in with the Google account the preview asks for.
4. If you need a billed, generally available IDE, leave preview and use Kiro or Cursor.

Frequently Asked Questions

Is it still free?

The 2026-08-17 homepage still says public preview is free.

Did Google buy Windsurf?

Not as a first-party sentence we could keep. Windsurf remains a Cognition product in this catalog.

Same as Google ADK?

No. ADK is the SDK. Antigravity is the IDE.

Alternatives

• Kiro: AWS IDE, generally available at $20 Pro.
• Cursor: Individual $20 / Pro $40.
• Google ADK: If you wanted the SDK, not an editor.

Tips

1. Fix any leftover youtu.be URLs. Embeds need a raw video id.
2. Do not paste acquisition rumors into the pricing table.
3. Confirm the model picker. Launch-era Gemini 3 names age fast.

Conclusion

Antigravity is still Google's free public-preview agent IDE. Start at antigravity.google, and switch to Kiro or Cursor if you need a paid GA seat.
