Most people have no clue this combo exists.
Antigravity with Claude Code is about to change how you build software forever.
Google released Antigravity—a free AI-powered development platform—on November 18, 2025, the same day it launched Gemini 3.
When you combine Antigravity with Claude Code, you get the power of a full development team that plans, builds, and tests your code—all automatically.
Let’s break down exactly how this works and why it’s one of the most powerful AI workflows right now.
What Is Antigravity?
Antigravity is Google’s free AI development environment.
Think of it as VS Code on steroids—powered by Gemini 3 Pro, Google’s most advanced model yet.
It helps you move from writing code manually to orchestrating AI agents that write, test, and debug code for you.
It has two main views:
- Editor View: Looks and feels like VS Code, compatible with all your favorite extensions.
- Manager View: The real game-changer. It lets you manage multiple AI agents working on different parts of your project simultaneously.
Each agent runs in its own sandboxed workspace.
You can track progress, view real-time updates, and oversee how tasks get executed—all in one place.
It’s like having a 24/7 software team that never sleeps.
Why Antigravity Works So Well with Claude Code
Antigravity uses Gemini 3 Pro for logic and planning, but it doesn’t stop there.
It also supports Claude 4.5 and Claude Opus 4.5 from Anthropic.
This means you can mix models depending on what you’re building.
Use Gemini for strategy and structure.
Use Claude Code for code generation and execution.
Switch between them to get the best of both worlds—planning precision and coding performance.
And right now?
It’s completely free to use during the public preview.
Available for Mac, Windows, and Linux.
How to Use Antigravity with Claude Code
This workflow is blowing up right now in AI development circles.
Here’s the step-by-step approach that saves you hours:
- Start in Antigravity.
Open the platform and select Gemini 3 Pro in “Plan Mode.” - Give it a high-level task.
For example: “Build a Chrome extension that summarizes YouTube transcripts.” - Let Antigravity create the full plan.
It generates your file structure, dependencies, components, and task breakdown automatically. - Export the plan.
Copy it to your clipboard—it includes everything Claude will need. - Switch to Claude Code.
Paste the plan directly into Claude Opus 4.5.
It’ll start writing clean, modular, production-ready code. - Return to Antigravity.
Use the built-in browser agents to test the code, validate outputs, and debug automatically.
This combination gives you planning (Gemini), execution (Claude), and testing (Antigravity)—all in one workflow.
The Five Rules for Perfect Workflow
To get the most out of Antigravity with Claude Code, follow these rules:
Rule 1: Start with one clear goal.
Give your AI one precise objective instead of multiple tasks.
Rule 2: Force detailed task breakdowns.
Use Antigravity to structure the project before Claude writes a single line.
Rule 3: Copy the entire plan.
Claude Code works best when you paste the full Antigravity plan verbatim.
Rule 4: Always test in Antigravity.
It’s built for multi-agent testing—don’t skip this step.
Rule 5: Never regenerate working code.
Every regeneration burns tokens and breaks consistency.
Understanding Token Efficiency
Both Gemini and Claude run on token pricing.
Gemini 3 Pro:
- $2 per million input tokens
- $12 per million output tokens
Claude Opus 4.5:
- $5 per million input tokens
- $25 per million output tokens
This means your workflow should minimize redundancy.
Plan once. Execute once. Test once.
That’s how professionals use Antigravity with Claude Code efficiently.
Anthropic’s own studies found Claude Code could finish tasks in one pass that normally take 45+ minutes of manual work.
The result? Clean, functional code that passes all tests on the first try.
Example Workflow
Let’s say you want to build a flight tracker app using real-time data.
In Antigravity:
- Give it a prompt like “Build a flight tracker with live updates.”
- It plans everything—tech stack, backend APIs, rate limiting, data flow.
Then move to Claude Code:
- Feed it the plan.
- It writes backend logic, builds APIs, creates the React frontend, and applies Tailwind CSS styling.
Then back to Antigravity:
- Run automated browser tests.
- The AI agents validate every component end-to-end.
Within an hour, you’ve got a working flight tracker app built entirely by AI.
Why This Is the Future of Software Development
AI isn’t replacing developers—it’s upgrading them.
You move from writing every line to directing the build process.
Your job becomes orchestration—defining structure, reviewing outputs, and steering the vision.
AI handles the labor.
Developers who learn this workflow now will dominate in the next 6–12 months.
Because this is where the entire industry is heading—agentic development.
Common Mistakes to Avoid
Mistake 1: Trying to code manually alongside AI.
Let the model handle execution; your focus should be oversight.
Mistake 2: Skipping the planning step.
If you skip Gemini’s plan generation, Claude Code will guess—and waste tokens.
Mistake 3: Ignoring test feedback.
Antigravity’s browser agents catch logic gaps before deployment—always review their reports.
Mistake 4: Starting with huge projects.
Begin small. Build one component, not a full app.
Mistake 5: Not documenting.
Save your workflows. Each iteration improves your AI prompt library and speed.
Real-World Results
Google demoed Antigravity using a flight tracker project during launch week.
Gemini 3 handled all planning and architecture.
Claude Opus 4.5 built and tested the system automatically.
Antigravity’s agents handled UI, logic, and stress testing simultaneously.
In less than an hour, it shipped a functional, production-ready app.
That’s how powerful this integration is.
How to Get Started
- Go to antigravity.google.
- Download and install the tool for your system.
- Sign in with your Google account.
- Follow the guided setup to connect Gemini 3.
- Set up Claude Code via your Anthropic account.
- Pro plan = $20/month
- Max plan = expanded usage
- Or pay-as-you-go via API access.
- Start small—one project, one goal.
- Plan in Antigravity. Build in Claude. Test in Antigravity.
Document what works and iterate.

Inside, you’ll see how creators are using Antigravity with Claude Code to automate app building, debugging, and prototyping faster than ever.
My Honest Take
These tools aren’t perfect.
They’ll make mistakes.
You still need to review and test your code.
But they’re incredibly powerful.
They save massive amounts of time and let you focus on creative and architectural decisions instead of syntax.
AI development is no longer about typing faster—it’s about thinking smarter.
If you learn to direct AI agents effectively, you’ll outpace developers who still write line by line.
This is your early window.
Master Antigravity with Claude Code now, and you’ll have a huge edge in the next wave of AI-native software engineering.
Final Thoughts
Antigravity with Claude Code is the ultimate combo for AI-powered development.
You plan, build, and test with AI agents—all inside one streamlined workflow.
No manual coding.
No wasted time.
Just output that works.
If you’re serious about using AI to automate software development, this is where to start.
