Hello,

Big Claude Code user here on terminal, but always curious to try new toys.

So far, Antigravity is a fairly good surprise, especially how it handles implementation plan as an artefact, but Gemini 3.0 allowance is absurdly small.

However, I've been playing a lot with the Chrome extension that allows Antigravity to control a Chrome browser.

NGL, it is a bit strange to use Gemini 3 or Claude here when Google offers Gemini 2.5 Computer Use, but this is not why I am here.

When you manipulate Chrome via the extension, it does two very interesting things:

1. It creates artifacts (both pictures and videos) of key moments of the browsing (you can find them in the folder ~/.gemini/antigravity/brain/(the_session ID)).

2. It also stores a massive amount of screenshots of the whole session in the folder ~/.gemini/antigravity/browser_recordings.

As you know, Gemini 3.0 is very strong in front‑end work and it feels you could use it in your design workflows:

1. Get Antigravity to browse a site/list of sites from a design and UX perspective.

2. Re‑use the artifacts and the automatic screenshots as reference to help you design and integrate your screenshots (by the way, Google updated Stitch with Nano Banana Pro + Automatic Export to AI Studio, very powerful).

Any thoughts?

---

Update based on the comments:

Yes, you can already manipulate the browser programmatically with MCP ChromeDevTools/Puppeteer/Playwright and in multiple other ways (BrowserOS, Browserbase)

What I found interesting about Antigravity were the autosave features, especially the videos, which are enabled by default.

Finally, one interesting thing here is that doing it this way gives you a fairly clean user agent (but also Antigravity refuses to solve captcha-type exercise).

Google just announced new AI First IDE - Google Antigravity. Looks like another VS Code Fork to me.

Good thing is its free for now with Gemini Pro 3.0

I’m stuck in a loop with the Antigravity IDE extension. I’ve installed it, restarted my computer, and even removed and reinstalled it, but every time I click "Open Browser (Preview)" I get the same prompt telling me to install the extension.

Is anyone else running into this issue?

Has anyone here used Google's Antigravity IDE yet?

I recently tested it out for a web stack project—the interface is very VS Code-like, and the AI (Gemini 3) squashed some long-standing bugs for me and even helped refactor a dormant project back to life. The whole multi-agent setup (where you can spawn coding, review, and refactor agents) is wild for streamlining bigger repos.

Curious:

- Do you find it just a polished VS Code clone with better AI, or does it offer something truly unique?

- Anyone pushed the agentic features in real-world workflows?

- Have you tried Chrome integration or in-IDE API testing?

- How does it stack up to Cursor and other AI IDEs?

Would love actual dev feedback—especially from those who've tried it on mid-to-large codebases.

Google has been rolling out a bunch of newer AI models this week.
Along with Gemini 3 Pro, which is now the world’s most advanced LLM, and Nano Banana 2, Google has released their own IDE.

This IDE ships with agentic AI features, powered by Gemini 3.

It's supposed to be a competitor with Cursor, and one of the big things about it is that it's free, although with no data privacy.

There was a lot of buzz around it, so I decided to give it a try.

Downloading

I first headed over to https://antigravity.google/download, and over there found something very interesting:

There's an exe available for Windows, a dmg for macOS, but on Linux I had to download and install it via the CLI.

While there's a lot of software out there that does that, and it kinda makes sense; it's mostly geeks who are using Linux, but here it feels a bit weird.
We're literally talking about an IDE, for devs, you can expect users on all platforms to be somewhat familiar with the terminal.

First-Time Setup

As part of the first-time setup, I had to sign in to my Google account, and this is where I ran into the first problem. It wouldn't get past signing in.

It turned out this was a bug on Google's end, and after waiting a bit until Google's devs sorted it out, I was able to sign in.

I was now able to give it a spin.

First Impressions

Antigravity turned out to be very familiar, it's basically VS Code with Google's Agent instead of Github Copilot, and a bit more of a modern UI.

Time to give Agent a try.

Problems

Workspaces

Problem number two: Agent kept insisting I need to setup a workspace, and that it can't do anything for me until I do that. This was pretty confusing, as in VS Code as soon as I open a folder, that becomes the active workspace, and I assumed that it would work the same way in Antigravity.

I'm still not sure if things work differently in Antigravity, or this is a bug in Agent.

After some back and forth with Agent, trying to figure out this workspace problem, I hit the next problem.

Rate-Limits

I had reached my rate limit for Gemini 3, even though I have a paid subscription for Gemini. After doing a little research, it turns out that I'm not the only one with this issue, many people are complaining that Agent has very low limits, even if you pay for Gemini, making it completely unusable.

Extensions

I tried installing the extensions I have in VS Code, and here I found Antigravity's next limitation. The IDE is basically identical to VS Code, so I assumed I would have access to all of the same extensions.

It turns out that Visual Studio Marketplace, where I had been downloading my extensions from in VS Code, is only available in VS Code itself, and not for any other forks. On other VS Code-based IDEs, extensions can be installed from Open VSX, which only has about 3,000 extensions, instead of Visual Studio Marketplace's 50k+ extensions.

Conclusion

In conclusion, while Google's new agentic IDE sounded promising, it's buggy and too limited to actually use, and I'm sticking with VS Code.

Copy cat of cursor???

Google just dropped "Antigravity" (antigravity.google) and claims it's an "Agent-First" IDE. I've been using Cursor heavily for the past few months, so I decided to give this a spin to see if it's just hype or a real competitor.

My key takeaways after testing it:

• The "Agent Manager" is the real deal: Unlike the linear chat in VS Code/Cursor, here you can spawn multiple agent threads. I managed to have one agent refactoring a messy LegacyUserProfile.js component while another agent was writing Jest tests for it simultaneously. It feels more like orchestration than coding.

• Model Access: It currently offers Gemini 3 Pro and Claude 3.5 Sonnet for free during the preview. That alone makes it worth the download.

• Installation: It's a VS Code fork, so migration (extensions, keybindings) took about 30 seconds.

The "Vibe Coding" Trap: I noticed that because it's so powerful, it's easy to get lazy. I did a test run generating a Frontend component from a screenshot.

• Attempt 1 (Lazy prompt): The code worked but the CSS was messy.

• Attempt 2 (Senior prompt): I explicitly asked for BEM methodology and semantic HTML. The result was production-ready.

Conclusion: It might not kill Cursor today, but the multi-agent workflow is definitely superior for complex tasks.

I made a full video breakdown showing the installation and the 3-agent demo in action if you want to see the UI: https://youtu.be/M06VEfzFHZY?si=W_3OVIzrSJY4IXBv

Has anyone else tried the multi-agent feature yet? How does it compare to Windsurf's flows for you?

Hey, usually i don't really use VS Code Forks in any way but wanted to try out Google's AntiGravity and found out there is no way to check your quota right now. Therefore i created a small VSX Plugin to make it easily viewable via the modal or in the status bar (image on github).
You can find the plugin here: https://github.com/Henrik-3/AntigravityQuota or directly in AntiGravity via the extensions tab by searching for Antigravity Quota (AGQ)

For questions or ideas feel free to reach out

If you love vibe coding: https://antigravity.google/

Supports models other than gemini such as GPT-OSS. Hopefully we will get instructions for running local models soon.

Update: Title should more appropriately say : windsurf clone . https://www.reuters.com/business/google-hires-windsurf-ceo-researchers-advance-ai-ambitions-2025-07-11/

If you use Antigravity, you've probably heard about Google increasing the quotas.

They didn't - you can just use more of the same quota at once, and you then wait a week to renew it.

Here is the screenshot. I am an Ultra user. Antigravity Version: 1.11.14. I hit this limit in a day worth of usage.

What's worse is after I switched to a free account the next day, I got practically the same amount of usage out of it. Like it's almost not noticeable that Ultra has more quota than free tier.

I developed software for 40 years and websites and apps for 20 years, but have been away from it for most of the last 4 years.

I recently started having fun with vibe coding, mainly using Claude Opus 4.5. I'm now developing a highly automated online business using a combo of Google Antigravity, Claude Code for writing the code, and Gemini 3 Pro for specifying, planning, and orchestrating. This way, I can distribute the load. If needed, due to limits, I can replace Gemini 3 Pro with Claude or another LLM.

I feel like I'm a dev on hyper steroids, or rather a whole dev team! It's an incredible combo, with all these amazing tools working together in one environment.

There are hiccups, I'm aware that everything's not perfect yet. But the power it gives us is so amazing, it's like a dream come true compared to the old days. Everyone can develop everything, we're only limited by our imagination.

I'm thoroughly enjoying this journey and wonder where it will take us in the coming months and years!

Just want to know how one can check their usage on antigravity for GPro and Claude sonnet 4.5. Helpful for planning

Google released a new IDE today, Antigravity https://antigravity.google/blog/introducing-google-antigravity

I tried it out, and here are my first thoughts:

- Antigravity has a planning mode that produces a plan + tasks. You can leave comments on portions of the docs just like you would leave feedback in Notion or Google Docs. I love this experience. It's much better than chatting your feedback and having the doc rewritten.

- Unfortunately Antigravity does NOT store these planning docs in your project. The IDE itself store in an app directory called "brain". When I hit a resource limit I tried to switch over to VS Code to finish the project. But now my planning is stuck in Antigravity, and copy/paste is the only way I can see to move it over

- I wasn't able to finish the project, but I look forward to using the Antigravity Browser Extension which promises to use Gemini 3 "computer use" capabilities to verify the front end of projects.

## Will I switch from GitHub Copilot?

It depends on how well I can get custom agents to work in GitHub Copilot and whether Antigravity will support something similar.

I like Antigravity's planning mode feedback UX, but it's not enough to make me switch.

And I'm not so hopeful that "computer use" will be better than just using Playwright's MCP server, and Playwright tests, and my own eyes.

Have anyone had this experience? Ive recently downloaded Antigravity IDE and downloaded its chrome extension. My Chrome homepage, which was used to show all my most visited websites has now changed to an Antigravity page.

Can anyone help me solve this?

I used Windsurf almost a year ago. It was pretty great for small projects, but there was still a lot of headache. I recently tried out Antigravity to make a chrome addon and it worked amazingly well. The models have improved so much. I'm now trying to decide if I should get a pro subscription to Windsurf or Antigravity. If I was still grandfathered into the old Windsurf price I'd go for that, but it looks like they changed the policy. Which one gets you more time with the best models?

So there is a problem when gemini corrupts the repo when changing even a single line, then it hard resets from my github main branch (I feel so uncomfortable to watch it use it auto without my permission, also it uses flags like --force and other dangerous ones directly on main branch) then "accidentally" deletes whole functions and make my repo worse then before. I thought its an issue with gemini 3 pro, but when I selected Sonnet 4.5 through Antigravity it shows the same behavior. Although its so polished when used with Claude code or GitHub Copilot, it is unusable atm for complex tasks.

Google dropped Antigravity on Nov 18th - their take on AI-assisted development.

What caught my attention:

• Free access (public preview with generous rate limits)

• Multi-model support: Gemini 3 Pro, Claude Sonnet 4.5, and GPT-OSS in one interface

• Agent-first architecture - autonomous multi-tasking across editor, terminal, and browser

• Built-in browser automation that tests your code and captures screenshots

• Playground mode for rapid prototyping without folder structure overhead

I spent 24 hours testing it:

Built an expense tracker and weather dashboard from natural language prompts. The automated browser testing is genuinely unique - the agent controls Chrome, tests the app, captures proof, and you can comment directly on screenshots to iterate.

The multi-model flexibility is the standout. If Gemini struggles with something, switch to Claude. If Claude hits a wall, try GPT-OSS. No vendor lock-in.

Rough edges:

Some early users report errors and slow generation with certain models. Still very much in preview.

Curious to hear what others think. Has anyone else tried it yet?
