Setup & Your First Agent
Antigravity installs in minutes and requires no API key configuration for standard use. This module covers every step from download to your first autonomous agent run.
Download Antigravity
Go to antigravity.google ā click Download for [your OS]. Available for macOS (Apple Silicon + Intel), Windows 10/11, and Ubuntu 20.04+. The installer is ~180MB.
Sign in with Google
On first launch, click Sign in with Google. Your Google account manages access to Gemini 3 Pro (default model) and usage quotas. No separate API key needed during the free preview period.
Import VS Code Settings (Optional)
Antigravity detects existing VS Code or Windsurf installations and offers to import extensions, themes, and keybindings. Accept this for a zero-friction transition ā your familiar environment transfers over.
Open Your Project
File ā Open Folder ā select your project root. Antigravity indexes the codebase immediately. For large projects (>50K lines), indexing takes 30ā60 seconds and runs in the background.
Select Your Model
Bottom status bar ā click the model name ā choose from: Gemini 3 Pro (default, fastest), Claude Sonnet 4.6 (best for complex reasoning), or GPT-4o. You can switch per-agent.
Dispatch Your First Agent
