# AI agent autonomously building your app
class Application:
    def __init__(self):
        self.agent = AntigravityAgent()

    def build(self, prompt):
        # Agent plans, executes & validates
        return self.agent.create(prompt)

Meet Your Autonomous AI Partner

Antigravity agents are granted unprecedented abilities, allowing them to act as a seamless extension of your team.

Autonomous Planning

AI agents independently analyze requirements, break down tasks, and create comprehensive implementation plans.

Direct System Access

Agents have direct access to the editor, terminal, and browser for complete end-to-end task management and validation.

Self-Validation

Agents autonomously test and validate their work in Chrome, ensuring correctness before delivery.

Gemini 3 Pro Powered

Leverages Google's most advanced AI model for superior code understanding, generation, and problem-solving.

Agent Manager

A dedicated interface to monitor and manage multiple autonomous agents across different projects and workspaces.

Progress Artifacts

Automatic generation of to-do lists, screenshots, and reports to track agent work and provide feedback.

Beyond Traditional Code Completion

Antigravity reimagines the IDE from an "agent-first" perspective, moving far beyond simple suggestions.

01

Task-Oriented Development

Operate by describing what you want to build. Agents handle the implementation, letting you focus on vision and architecture.

02

End-to-End Automation

From a single prompt, agents create subtasks, execute them, test results, and generate a final product walkthrough.

03

Browser UI Testing

Unique browser sub-agents autonomously test and validate user interfaces, ensuring your app works before deployment.

Flexible AI Model Support

Choose the AI brain that best fits your development needs.

Frequently Asked Questions

What makes Antigravity different from other AI coding tools?

Antigravity is built from the ground up as an "agent-first" IDE. Unlike traditional tools offering code completion or chat, our AI agents have direct access to your editor, terminal, and browser, enabling them to autonomously plan, execute, and validate entire features.

Is Antigravity free to use?

Yes, the public preview is completely free for all developers. We are committed to making advanced AI development tools accessible to everyone during this period.

Which programming languages are supported?

Antigravity supports all major programming languages, including Python, JavaScript, TypeScript, Java, C++, Go, Rust, and many more. The AI agents are trained on diverse codebases and can work with any language.

How does the autonomous testing work?

Our browser sub-agents can launch Chrome, interact with your application's UI, and automatically verify functionality. They test user flows, check for errors, and validate that features work as expected before presenting results to you.

Is my code data secure and private?

Yes, we take security seriously. Your code is processed securely, and we follow industry-standard encryption practices. You maintain full ownership of your code and intellectual property.
