Google Antigravity Review: AI Coding Platform Launches with Major Issues

Google Antigravity is new tool in coding market. It’s a bit of a mixed bag. They announced it on November 17 alongside their new Gemini 3 AI model. The idea behind it sounds pretty cool. Basically AI agents can write code for you while you focus on the bigger picture. But here’s the thing. Early users are running into some pretty frustrating problems. It makes you wonder if it’s actually ready for prime time.

What is Google Antigravity?

Antigravity is Google’s take on AI coding. It works differently than tools like GitHub Copilot. Instead of just suggesting code while you type, it’s more like having AI teammates. They can plan out entire features. They write the code. They even test it in a browser. Pretty wild, right?

It’s built on top of Visual Studio Code. If you’ve used that before, it’ll feel familiar. The main difference is you’ve got this agent manager window. You can see what the AI is working on. You also get the regular code editor and an automated browser for testing web apps. Under the hood, it mostly runs on Google’s Gemini 3 Pro model. You can also use Claude Sonnet or GPT if you want.

The whole pitch is simple. You describe what you need built. The agents figure out how to actually do it. You’re basically the architect. The AI handles the grunt work.

Key Features That Stand Out

Antigravity has two main modes. There’s Editor view. It’s more traditional. You’re hands on with the code and the AI helps out from the sidebar. Then there’s Manager view. This is where things get interesting. You can have multiple agents working on different tasks at the same time. They work across separate workspaces.

One thing I think is clever is their Artifacts feature. Instead of drowning you in logs of everything the AI is doing, it creates these digestible summaries. Task lists, plans, screenshots, stuff like that. It makes it way easier to review what’s happening. You don’t get overwhelmed.

The Chrome extension is probably the coolest part. Agents can actually open websites in a real browser. They click around. They see what happens. Then they adjust the code based on what they observe. That’s pretty useful if you’re building web apps. You need to verify things visually.

Problems Users Are Experiencing

Okay, so here’s where things get rough. The biggest complaint is that you run out of credits super fast. People on Hacker News are saying they’re hitting their limit after just 20 minutes or so of actual work. One person literally said they started using it for their project. They ran out of credits. They just went back to Cursor.

And get this. There’s no way to buy more credits right now. Google says they give you generous rate limits that refresh every five hours. That’s clearly not cutting it for serious development work.

On top of the credit problem, there are stability issues. Tech journalist Simon Willison tested it. He kept getting errors saying agent execution terminated due to model provider overload. Other publications ran into the same thing. The agent would just spin forever. Then it would crash with an overload message.

It kind of seems like Google’s servers are getting hammered. They can’t keep up with everyone trying the free preview.

Security Concerns You Should Know

Here’s something that caught my attention. Google’s own terms of service straight up say Antigravity is known to have certain security limitations. They specifically call out risks like data getting leaked or unsafe code execution.

The weird part is that the default settings give the AI agents a lot of freedom. They can do stuff without asking you first. If Google’s so worried about security that they’re putting warnings in the terms, why would they make that the default? Doesn’t really add up.

Bottom line. Don’t use this for anything with sensitive data or proprietary code right now. The risks are real. Google’s being pretty upfront about them.

Additional Limitations to Consider

A few other annoying things. If you use Google Workspace for work, Antigravity doesn’t play nice with it. Google actually recommends switching to a personal Gmail account. That’s kind of a pain if you’ve got everything set up with your work account.

Also, it uses this Open VSX extension registry instead of the full Visual Studio Code marketplace. You can still get tons of extensions. But the selection isn’t as complete as what you might be used to.

Should You Try Antigravity?

Look, the concept is really cool. The idea of AI agents that can handle entire features while you focus on architecture. That’s legitimately the future of coding. The artifact system and browser automation show some real innovation.

But right now? It’s too rough around the edges. Between running out of credits with no way to get more, constant overload errors, and legitimate security concerns, most people should probably wait. It’s available for free on Windows, Mac, and Linux. Feel free to download it and mess around if you’re curious. Just keep your regular tools handy. You’ll probably need them.

Google’s planning to add paid Team and Enterprise tiers eventually. But who knows what that’ll cost. These AI agents use a lot of compute power.
