Google Antigravity for Windows: First Look and Download Guide

Google Antigravity is a brand new coding app from Google, and it is completely free to download right now. Unlike traditional code editors where you type everything yourself, Antigravity lets you tell an AI agent what you want built, and the AI does the heavy lifting for you. It writes the code, tests it, and even checks if the final result looks right in a browser.

Think of it like this: instead of writing every single line of code by hand, you become the project manager.

You describe what you need (“build me a login page” or “fix the layout on mobile”) and the AI handles the rest. You can even run multiple AI agents at the same time, each working on a different task.

It is built on top of the same foundation as VS Code, so if you have used VS Code before, the interface will feel familiar.

But under the hood, it is powered by Google’s latest Gemini Pro AI model, which is what makes the magic happen.

This post covers everything you need to know: the main features, how to install it on Windows 11/10, and how to get past a few common setup issues.

What Is Google Antigravity?

Google Antigravity is the new “agentic development platform” from Google, available now as a Public Preview. While it looks like standard VS Code on the surface, it replaces the traditional file explorer workflow with a Mission Control interface designed exclusively for the AI era.

The groundbreaking shift here is the Agent Manager View. Unlike Visual Studio 2026, which heavily focuses on AI copilots assisting you as you type, Antigravity is built from the ground up for autonomous agents.

You assign a task like “refactor the login flow and test it in the browser” and the agent spins itself up, edits multiple files, runs terminal commands, and actually verifies its work using a built-in Chrome instance. It runs on the latest stable Gemini Pro model (running 3.1 as of this writing, but constantly updating), utilizing a massive context window to instantly understand your entire repository, external documentation, and even live screenshots of your app.

Key Features: What Can You Do?

Here are the biggest features that set Antigravity apart from a regular code editor.

How to Download and Install Antigravity on Windows

Installing Antigravity is straightforward on Windows, though the launch servers occasionally still throw a few hiccups regarding authentication.

1. Step 1: Download the installer for your OS directly from the official Google Antigravity downloads page.
2. Step 2: Run the downloaded installer (Antigravity_Setup_x64.exe).
3. Step 3: Important Note on Setup: When you first launch the app, you will be asked to sign in with your Google account to connect to the AI features.
4. Step 4: If you get stuck spinning on “Setting up your account”: Change your default Windows browser to Chrome temporarily before signing in. Many users report that Edge or Brave can occasionally cause the auth token to hang. Close the app completely and try again.
5. Step 5: Once successfully logged in, choose to import your existing keybindings and extensions from VS Code to hit the ground running!

Google Antigravity vs The Competition

Is this the highly-anticipated Cursor killer? Here is how Antigravity stacks up against the other heavy hitters in the modern AI IDE space.

Quick Start Guide: First Steps

Ready to try it out? Here is how to get started once you have it installed:

1. Open Mission Control: Don’t just open a file to start typing. Hit Cmd/Ctrl + I to open the Agent interface.
2. Spawn an Agent: Type “Scan my entire repo and create a README.md explaining the architecture.” Watch it independently read your files and generate the artifact.
3. Visual Debugging: Run your localhost server. Click the “Eye” icon in the chat to let the agent actively see your browser window. Tell it: “Fix the alignment on that navbar,” and watch it visually inspect the element and apply the code fix in real-time.

How to Change Your AI Intelligence Engine

One of Antigravity’s biggest strengths is that it does not lock you into Google’s ecosystem. Because model capabilities leapfrog each other constantly (Gemini today, Claude tomorrow, GPT the next), you can easily swap the underlying brain of your autonomous agents.

Here is how to switch models safely and efficiently to ensure you are always using the smartest tech available:

1. Open the Command Palette: Press Ctrl + Shift + P and type Model Switcher.
2. Select Local vs Cloud: You can choose the official cloud provider API, or route through a local instance if you have the hardware to run open-source weights.
3. Download the Associated Extension: For models not built natively into the app, you need to grab their official connectors from the Marketplace:
   • OpenAI Codex / GPT Connectors
   • Claude Workbench (Anthropic)
   • Grok Official Integration
4. Enter Your API Key: Once the extension is active, click the “Model” dropdown button in the top right of your Mission Control manager panel and paste in your respective API key (from Anthropic, OpenAI, or xAI).
