Experience the future of software development with AI agents that act as true coding partners
Autonomous Planning
AI agents independently analyze requirements, break down tasks, and create comprehensive implementation plans without manual intervention.
Direct System Access
Unprecedented permissions with direct access to editor, terminal, and browser for complete end-to-end task management and validation.
Self-Validation
Agents autonomously test and validate their work within Chrome, ensuring quality and correctness before presenting results to you.
Gemini 3 Pro Powered
Leverages Google's most advanced AI model for superior code understanding, generation, and problem-solving capabilities.
Agent Manager Interface
Dedicated interface to monitor and manage multiple autonomous agents across different projects and workspaces simultaneously.
Progress Artifacts
Automatic generation of to-do lists, screenshots, and progress reports to track agent work and provide contextual feedback.
Beyond Traditional Code Completion
Antigravity reimagines the IDE from an agent-first perspective, moving far beyond simple autocomplete
Task-Oriented Development
Operate at a higher level by describing what you want to build. Agents handle the implementation details, allowing you to focus on product vision and architecture.
End-to-End Automation
From a single prompt, agents create subtasks, execute them, test the results, and generate comprehensive walkthroughs of the final product.
Browser-Based UI Testing
Unique browser subagents autonomously test and validate user interfaces, ensuring your applications work correctly before deployment.
Multi-Workspace Management
Manage multiple AI agents working on different projects simultaneously with dedicated workspace organization and monitoring tools.
Continuous Learning
Agents learn from your feedback and past work, improving their understanding of your coding style and project requirements over time.
Detailed Verification Process
Advanced verification workflows ensure code quality, security, and performance standards are met before presenting results.

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 that offer code completion or chat interfaces, 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're committed to making advanced AI development tools accessible to everyone during this preview 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 subagents can launch Chrome, interact with your application's UI, and verify functionality automatically. They test user flows, check for errors, and validate that features work as expected before presenting results to you.
Can I use my own AI models?
Currently, Antigravity supports Gemini 3 Pro, Claude Sonnet 4.5, and GPT-OSS. We're working on expanding model support and may add custom model integration in future releases.
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.
