What is Google Antigravity?

Google Antigravity is a free tool that acts as a coding environment, giving you access to various free APIs for building digital tools [web:1]. Unlike traditional automation tools that often require paid software and limited testing, Antigravity offers a sandbox for innovation without the usual overhead.

One of its most compelling features is access to high-tier models powered by Gemini 3 Pro, Gemini 3 Deep Think, and Gemini 3 Flash [web:1][web:4]. This lets you compare results across models to find the best output for your project.

Getting Started: The Setup Process

The journey from beginner to expert begins with a proper local setup. This stands out as one of the tool’s primary advantages: it lets you code locally, keeping your files private and easily accessible for future edits [web:3][web:7].

Step 1: Local Installation and Folder Management

Start by downloading the tool at antigravity.google [web:5]. Once installed:

• Open the tool locally on your machine.
• Create a new folder for your project (e.g., “Live Stream” or “New Web Project”).
• Allow the tool to access this folder to begin generating files.

Step 2: Choosing Your Model

Switch between models based on your needs. For high-quality reasoning, choose advanced Gemini models. When you’re in a hurry, opt for faster generation modes [web:1].

The Workflow: Planning, Building, and Iterating

Beginners often jump straight into coding—a common mistake. Google Antigravity promotes a structured, professional approach via its “Planning Mode” [web:4].

The Importance of Planning Mode

Before writing a single line of code, generate a comprehensive checklist. Describe your project in plain English, and the AI plans copywriting, design, visual assets, and verification steps [web:7].

Real-Time Building and Visual Assets

With the plan ready, switch to implementation. The tool can:

• Generate code: It writes CSS and HTML files, which appear in your project folder in real-time.
• Create visuals: AI models generate images directly in the environment [web:6].
• Handle feedback: Dislike an image or copy length? Tell the tool to fix it, and it rewrites assets immediately.

Why Use Antigravity Over Other AI Tools?

You might compare it to platforms like Cursor or AI Studio. While those shine for quick projects, Google Antigravity excels for complex, multi-file ones [web:4][web:10].

• Local Storage: All files appear on the left-hand side of your IDE, simplifying whole-website management.
• Privacy: Professionals prefer local coding to keep intellectual property on their own hardware [web:3].
• Iterative Agent Workflow: AI agents launch browsers, take screenshots, analyze, and redesign until standards are met [web:2].

Real-World Use Case

Consider creating a sales page for a community like the AI Profit Boardroom. Instruct the tool to use a high-impact style with a “value stack” design, and you’ll have a professional landing page in minutes.

Practical Tips for Power Users

• Be descriptive: Don’t just request a “website.” Share your business context, the problem you solve, and your specific call to action (CTA).
• Use the Browser Agent: Let it launch a browser for verification. This “positive feedback loop” confirms designs look great on-screen [web:7].
• Don’t panic over errors: If the AI misinterprets, add more context. Direct it to lengthen copy, beautify designs, or tweak layouts anytime.
• Host for free: Deploy local files on platforms like Netlify to go live.
