My Experience With Google Antigravity: How I Refactored Easy Kit

So, Google just dropped something pretty wild into the dev tools arena: Google Antigravity, their new AI-native IDE powered by Gemini 3. And honestly? It's been a game-changer for how I approach coding. I recently used it to completely refactor Easy Kit Utils, and I wanted to share my thoughts on this new tool that's got everyone talking.

If you've been following the AI coding assistant space, you've probably heard the buzz around Cursor, Windsurf, and other tools. Well, Google decided to enter the chat with a different approach: instead of just assisting you while you code, Antigravity lets autonomous agents do the heavy lifting while you act more like an architect than a bricklayer.

First things first, let's clear up what we're dealing with here. Antigravity isn't just another VS Code fork with AI bolted on. It's built from the ground up as an "agent-first" development platform. What does that mean in practice?

Instead of having an AI chatbot sitting in a sidebar suggesting code completions, Antigravity gives you autonomous agents that can work across three main surfaces: the code editor, the terminal, and an integrated browser. These agents don't just write code snippets,they plan entire workflows, execute complex tasks, and even validate their own work by testing in the browser.

The core concept Google is pushing is what they call "vibe coding." The idea is simple but powerful: describe what you want in natural language, and the agent figures out the implementation details. No more wrestling with syntax or hunting through documentation for that one specific method you need. Just tell it what you're trying to achieve, and it handles the rest.

When you launch Antigravity, you're not greeted with a file tree like traditional IDEs. Instead, you see the Agent Manager, basically a mission control dashboard where you can spawn multiple agents working on different tasks simultaneously. It's like having a team of developers working in parallel, except they're all AI.

After spending significant time with Antigravity while refactoring Easy Kit Utils, here are the areas where it genuinely impressed me:

This is the big one. When I started the Easy Kit Utils refactoring, I could give Antigravity high-level objectives like "refactor the string utilities to use modern ES6+ syntax and add comprehensive type definitions." The agent would then break this down into subtasks, create an implementation plan, and execute it. I wasn't sitting there writing every line, I
