Install and Setup
Download the IDE, sign in with Google, pick a model, connect Chrome.
Antigravity installs like any desktop IDE — macOS, Windows, or Linux — and is free in public preview, with generous rate limits that refresh every few hours. Three setup moves are worth making on day one: import your VS Code settings, pick your default model, and connect Chrome so agents can drive a real browser.
Download and install
Grab the installer from antigravity.google. On first launch it offers to import your VS Code settings, keybindings, and extensions — take it; the editor will feel like home immediately.

Preview access is tied to your Google account. During onboarding you'll also pick a default autonomy level — how much the agent checks in before acting. Start conservative; you can loosen it later.
VerifyYou land on the editor with the agent side panel open and your account shown in the corner.Pick your default model
Gemini 3 Pro is the default; the picker also offers Anthropic's Claude models and open-weight OpenAI models. The habit to build: frontier model for planning-heavy work, faster models for mechanical chores.

Agents verify frontend work by driving Chrome — opening your app, clicking through flows, screenshotting, recording. That requires the Antigravity extension in Chrome.
Ask the agent: "Open localhost:3000 in the browser and screenshot the homepage."VerifyA Chrome window under agent control opens, and a screenshot lands in the conversation.Open your first workspace
File → Open Folder on a real repo. A workspace is the unit agents are assigned to — the Manager can run agents across several at once.
VerifyThe agent panel can answer a question about the repo ('what does this project do?') with real file references.
