Google Antigravity: The New “Agent-First” IDE & The Chrome Extension Trap You Need to Know

amy 24/12/2025

Last week, social media platforms like X and Reddit were flooded with hype. Google has officially released Antigravity, a tool designed to shift the coding paradigm from mere autocomplete to fully autonomous AI agents.

The premise is that we are no longer just writing functions; we are commanding agents to plan, execute, and test workflows.

But for many early adopters, this “future of coding” began with a heart-stopping moment of panic.

The Antigravity Extension Panic

In fact, countless users installed the required Antigravity Browser Control extension only to find their digital lives wiped clean.

Bookmarks, history, and saved passwords seemingly vanished in an instant.

Currently, developers are scrambling to forums to ask if Google just deleted their data.

But there is a specific mechanism hiding in the background that explains this terrifying user experience, and Google has been less than clear about it.

Why Your Chrome Data Disappeared

The Antigravity extension essentially turns a Chrome window into a remote-controlled drone for the AI.

To do this safely, it likely hijacked your Chrome Profile or forced you into a temporary “Agent Sandbox.”

Because the AI needs a clean environment to click buttons and “see” the screen without accidentally posting to your Facebook or spending money via your saved credit cards, it isolates itself entirely.

Instead of clearly communicating this profile switch, Google’s implementation has left users thinking they have suffered a factory reset.

The fix is simple, clicking the profile icon and switching back to your default “Person 1” profile, but the initial shock serves as a stark reminder of what this tool actually is.

The Rise of “Agent-First” Coding

Why are we risking these heart attacks when tools like VS Code already exist?

Because Google Antigravity represents a fundamental shift from “AI Assistance” to “AI Agency.”

The goal is to reduce context switching.

The “Old Way” involved writing code, hitting an error, and Googling the fix.

The “Antigravity Way” involves telling an Agent Manager to fix the bug, while you sit back and watch it edit files and browse the web autonomously.

But there is a giant competitor standing in the way of Google’s dominance that has been winning the hearts of developers for the last year.

Can Google Antigravity Defeat Cursor?

Cursor has effectively been the king of AI coding. It is an “AI-First” editor that feels like a turbocharged VS Code.

It is fast, stable, and acts like a hyper-efficient Junior Developer sitting next to you, typing whatever you say.

Google, however, is playing a different game entirely.

Antigravity acts more like a remote contractor. You send an email (or a prompt), and they do the work unsupervised.

This distinction is crucial. Antigravity will only defeat Cursor if these Agents become reliable enough to work without us watching them.

Right now, the browser control is impressive, but if the Agent gets stuck in a loop clicking the wrong button, you save absolutely no time.

A Warning for the Future of Software

This is no surprise in fact if you understand Google and its desire for ecosystem control.

While Cursor keeps the developer in the driver’s seat, Google is building a future where the developer is merely an architect, delegating the actual implementation to Google’s own black box.

If you are a builder who loves the craft of code, you should probably stick with Cursor.

But if you are a manager who wants to delegate details and verify results later, Google Antigravity is the future you are likely barreling toward.

Such a shift in how we build software should be a big red flag: We are moving from a world where we write the code, to a world where we merely supervise the machine that writes it for us.

And all we have to do is install an extension, and pretend our panic didn’t happen.
