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.
