Google Antigravity: The New AI IDE with Gemini 3 (2025)

What is Google Antigravity?

Google Antigravity is a revolutionary agentic development platform (Agentic IDE) that enables developers to work at a higher, task-oriented level. Instead of just suggesting code, the AI becomes an active partner in the development process.

The IDE is specifically designed for agentic workflows and leverages the advanced reasoning and coding capabilities of Gemini 3 Pro to help developers plan, execute, and validate software tasks.

Core Features of Google Antigravity

🚀 Key Features: What Can Google Antigravity Do?

Google Antigravity fundamentally differs from traditional code assistants like GitHub Copilot. Here are the main features:

1. Agentic Development

The biggest difference from traditional AI coding tools: Antigravity uses AI agents that can act autonomously. These agents have direct access to:

• Code Editor: The AI can directly write, edit, and refactor code
• Terminal: Execute commands, run tests, install dependencies
• Browser: Validate and test changes in real-time

2. Multi-Pane Workflow Interface

Antigravity offers an innovative multi-pane interface, similar to modern IDEs like Warp or Cursor 2.0:

• ChatGPT-Style Prompt Window: Communicate with the AI in natural language
• Code Editor Panel: See changes in real-time
• Terminal Panel: Track commands and build processes
• Browser Preview: Instantly see how your changes look

3. Advanced Reasoning with Gemini 3

Antigravity uses Gemini 3 Pro, which according to Google sets new benchmark records for reasoning tasks. This means specifically:

• Better understanding of complex programming tasks
• Smarter code architecture decisions
• Detection of edge cases and potential bugs
• Ability to solve multi-step problems

4. Plan-Execute-Validate Workflow

The workflow in Antigravity follows a structured approach:

1. Plan: The AI analyzes your task and creates a step-by-step plan
2. Execute: The AI executes individual steps (write code, terminal commands, etc.)
3. Validate: The AI tests the implementation in browser or terminal

🔥 Google Antigravity vs. Competition: How Does It Stand Out?

The AI coding tools market is fiercely competitive. Here's how Antigravity stands out from other tools:

🎯 Who Should Use Google Antigravity?

Perfect For:

• Full-Stack Developers: Browser integration makes frontend development particularly productive
• Startup Founders: Rapid prototyping and MVP development
• DevOps Engineers: Automation of deployment tasks and Infrastructure-as-Code
• Learners: The AI explains decisions and helps with understanding
• Solo Developers: Partially replaces an entire team through autonomous task execution

Less Suitable For:

• Teams with very specific code guidelines (the AI can be "opinionated")
• Projects with highest security requirements (cloud-based AI)
• Developers who want absolute control over every step

• Rate limits management

Step 3: Your First Project

Start with a simple project to understand how it works:

Watch how Antigravity:

• Creates a plan
• Creates files (index.html, styles.css, script.js)
• Writes the code
• Starts a local server
• Shows the result in the browser

🔐 Security and Privacy

What You Should Know:

• Cloud-based: Your code is sent to Google servers for processing
• No local models: Unlike some competitors, Gemini 3 doesn't run locally
• Data usage: Google may use your inputs to improve the AI (can be disabled in settings)

Our Verdict

❓ Frequently Asked Questions (FAQ)

Is Google Antigravity really free?

Yes, during the Public Preview phase, Antigravity is completely free with generous rate limits. Google has not yet announced what the pricing model will look like after the preview phase.

Can I use Antigravity offline?

No, Antigravity requires an internet connection as the AI processing happens on Google servers. There's currently no offline option.

Which programming languages are supported?

Antigravity supports all common programming languages, especially: JavaScript/TypeScript, Python, Go, Rust, Java, Kotlin, Swift, and many more.

How does Antigravity differ from GitHub Copilot?

The main difference: Copilot makes code suggestions that you accept or reject. Antigravity is an autonomous agent that can independently plan, write code, execute terminal commands, and test in the browser.

Is my code safe? What happens with my data?

Your code is sent to Google servers for processing. Google may use this data to improve the AI (can be disabled). For highly sensitive projects, you should carefully review the privacy policies.

Can I use Antigravity with my existing VSCode setup?

Antigravity is a standalone IDE. However, there is Gemini 3 integration in other IDEs like Cursor, JetBrains, etc. But the full agentic features are only available in the Antigravity desktop app.

Do I need programming knowledge to use Antigravity?

Basic programming knowledge is recommended. While Antigravity can code autonomously, you need to be able to understand and validate the results. For absolute beginners, the learning curve might be steep.
