Google Antigravity Review: The Free "Agent-First" IDE That Might Kill VS Code

 

Google Antigravity Review: The Free "Agent-First" IDE That Might Kill VS Code

It’s called Google Antigravity. It is an experimental "Agentic IDE" that completely reimagines how we write code. While everyone else is paying $20/month for Cursor, Google has quietly released this beast completely for free in Public Preview.

If you are a student, a junior dev, or just broke, this is your golden ticket. But you need to move fast tools this powerful don’t stay free forever.

What is Google Antigravity?

At its core, Antigravity is a fork of VS Code. This means all your favorite extensions, themes, and keybindings work out of the box.

But here is the twist: It isn't built for Copilots (AI that just auto-completes your lines). It is built for Agents.

A "Copilot" waits for you to type. An "Agent" takes a goal and executes it autonomously. Antigravity is designed to let you be the Architect while the AI acts as the Builder.

Top 3 Features That Change The Game

Google didn't just add a chat window to VS Code; they rebuilt the workflow. Here is what makes it special:

1. The Agent Manager (Mission Control)

This is the killer feature. Instead of a single chat box, you get a dedicated "Mission Control" center.

• Delegation: You don't just ask questions; you assign Tasks. Example: "Refactor the navbar to be responsive and fix the z-index bug."

• Planning: The AI doesn't just start guessing. It generates a step-by-step plan, shows it to you for approval, and then executes it across multiple files.

• Verification: It doesn't stop after writing code. It runs the code to see if it actually works.

2. The Built-in Headless Browser

This is where Antigravity humiliates other IDEs. It comes with a fully integrated Chrome instance that the Agent can control.

• It Clicks for You: The AI can literally launch your web app, click buttons, fill out forms, and navigate menus to test its own changes.

• Visual Debugging: If a button is off-center, the Agent "sees" it using computer vision and fixes the CSS automatically.

• No More Context Switching: You never have to leave the IDE to check if your code works.

3. Gemini 3 Integration

Antigravity is powered by Gemini 3, Google's newest frontier model.

• Massive Context Window: Gemini 3 has a context window so large it can basically read your entire repository at once. It understands how a change in utils.js breaks a component in App.jsx without you needing to explain it.

• Reasoning Capabilities: It is significantly better at logic and complex refactoring than previous models, making it less likely to hallucinate broken code.

The Comparison: Antigravity vs. Cursor

Cursor has been the king of AI editors for a while, but Antigravity is coming for the throne.

• Cost: Cursor’s best features are locked behind a $20/month subscription. Antigravity is currently FREE.

• Workflow: Cursor is amazing at editing code you are looking at. Antigravity is superior at managing tasks you don't want to look at.

• Ecosystem: Since Antigravity is a VS Code fork, it feels familiar immediately, but the Google Cloud integration is much tighter.

How to Get It

This is an experimental Public Preview. Google is known for killing projects or locking them behind paywalls once they mature.

Do not wait.

1. Go to antigravity.google.

2. Download the installer for your OS (Mac/Windows/Linux).

3. Import your VS Code settings during setup.

Conclusion

I’ve been using Antigravity for 2-3 months, and I haven't opened standard VS Code except for college pracicals. The ability to tell an agent "Fix this error" and watch it actually browse my localhost and fix it is magical and it do not broke the previous working code much. 

Download it this weekend. Learn the "Agentic" workflow. Even if you go back to Cursor later, experiencing Gemini 3 inside a native agentic environment is something every developer needs to see.

Go break some code.
