Remember when we thought GitHub Copilot was magic? It feels like that was a decade ago.
The AI coding wars have been exhausting. First, we all moved to VS Code. Then Cursor came along and blew our minds with “Tab” autocomplete. Then Windsurf dropped and we thought, “Okay, this is peak flow.”
But Google just woke up and chose violence.
They just released Google Antigravity (powered by the new Gemini 3), and honestly? It’s scary good. It’s not just helping me write code; it’s actively trying to take my job. After spending the weekend with the Public Preview, here is why I think this might be the IDE that finally makes me uninstall VS Code.
What is Google Antigravity?
If Cursor is an “AI Assistant,” Antigravity is an “AI Employee.”
It’s a new IDE from Google that focuses on Agentic Development. Instead of you typing code and the AI suggesting the next line, you treat Antigravity like a junior dev. You give it a ticket—“Refactor the auth middleware and add 2FA”—and it spins up an autonomous agent to do it.
It doesn’t just guess. It runs the code, opens a headless Chrome browser, tests the login, records a video of it working, and then asks for your review.
How to Install Google Antigravity
Getting this set up is surprisingly easy, though it’s heavy on RAM (Gemini 3 needs space to breathe).
For Windows Users
- Download the Installer: Grab the
.exefrom the Official Antigravity Portal. - Run as Admin: Right-click the installer and select “Run as Administrator” (required for the deep system linking features).
- The “SmartScreen” Scare: Windows might flag it since it’s brand new. Just click More Info > Run Anyway.
- WSL2 Integration: If you use WSL2, Antigravity detects it automatically. It will ask to install the “Gemini Bridge” inside your Linux distro—click Yes. This is crucial for terminal commands to work correctly.
For Mac Users
- Get the DMG: Download the Universal Mac Build from the Download Page.
- Drag & Drop: Pull the icon into your
Applicationsfolder. - Grant Permissions: This is the annoying part. On first launch, macOS will freak out because Antigravity wants to “Control your computer.” You must go to
System Settings > Privacy & Security > Accessibilityand toggle Antigravity ON.- Why? Because the AI agent needs to be able to “click” things in the browser to test your web apps.
- Sign In: Authenticate with your Google Dev profile.
The Showdown: Antigravity vs. The Giants
I know, you just got your Cursor keybindings perfect. Is it worth switching? Here is the raw breakdown comparing the new kid on the block against the current titans.
| Feature | Google Antigravity | Cursor | Windsurf (Codeium) | Visual Studio Code |
| The Vibe | “Manager Mode” (You delegate, it works). | “Flow Mode” (You type, it predicts). | “Deep Context” (It knows your whole codebase). | “DIY” (Build it yourself). |
| AI Brain | Gemini 3 Pro (Native). | Claude 3.5 Sonnet (Usually). | Cascade Flow. | Copilot (Optional). |
| Killer Feature | Artifacts: It sends you video proof that the code works before you merge it. | Cursor Tab: The autocomplete is still the fastest in the game. | Context Awareness: It rarely hallucinates file paths. | Extensions: Still has the biggest plugin marketplace. |
| Cost | Free (during Preview). | $20/mo for Pro. | $20/mo for Pro. | Free. |
| Verdict | Best for Full-Stack apps and complex refactors. | Best for Scripting and fast iteration. | Best for Enterprise codebases. | Best if you hate change. |

Conclusion
Look, I love Cursor. It changed how I code. But Google Antigravity feels different. It feels like a glimpse into a future where we write less code and make more decisions.
Is it perfect? No. The agents sometimes get stuck in loops, and it eats RAM like Chrome eats battery life. But when you ask it to fix a bug and it comes back 30 seconds later with a fixed file and a video showing the fix working… that is a magical moment.
If you are tired of typing boilerplate and want to start managing agents, give it a download. Just don’t blame me if you forget how to write a for loop by next month.
