I asked Google Antigravity to build a website, then let Claude Code redesign it

AI coding agents have become quite capable, and building a website from scratch is no longer as challenging as it once was. However, I wanted to see what happens when I let one AI agent build a website and then ask another to take over and give it a complete makeover.

To put this idea to the test, I asked Gemini in Google Antigravity to build a website, then handed the entire project to Claude Code for a redesign. I wanted to see whether this two-agent approach could improve the final product.

Why didn’t I just start with Claude Code?

I wanted the best of both worlds

You might wonder why I didn’t simply ask Claude Code to build the website in the first place. Well, I had a different workflow in mind. Building an entire website from scratch requires plenty of planning, prompting, testing, and refinements, all of which can eat into Claude Code’s token usage and limits.

Since Google Antigravity is already quite capable of handling the initial development, I wanted to use it for the groundwork and reserve Claude Code for the creative overhaul.

I was also curious whether a fresh AI agent, without being tied to the original design decisions, could spot shortcomings and deliver something better. It’s a practical experiment in splitting development tasks between two powerful coding agents.

Building the foundation from scratch

For this experiment, I decided to create a fictional B2C perfume brand called Aurevi. The idea was to build a premium yet accessible perfume shopping website. And I wasn’t looking for a basic landing page, either.

My original prompt was quite detailed. I wanted a beautiful homepage, a complete product catalog with filters and sorting options, dedicated product pages, an interactive fragrance-finder quiz, a shopping cart, and a simulated checkout experience.

Google Antigravity, powered by Gemini 3.8, did an impressive job. I loved its choice of typography, icons, spacing, and subtle gradients. The Shop by Mood section looked fantastic with different gradient backgrounds. However, it wasn’t perfect.

The product pictures weren’t convincing. I also noticed several smaller details that weren’t implemented quite as I had envisioned. Nothing was fundamentally broken, but the website still needed that final layer of refinement.

Overall, I would say Antigravity got me about 90% of the way there. I already had a functional, visually appealing website with nearly everything I asked for. Instead of spending more time fine-tuning the remaining details in Antigravity, I decided to hand the entire project to Claude Code and see whether it could take care of that final 10%.

Time for a complete AI makeover

With the initial website ready, it was time to bring Claude Code into the picture. I opened the existing Aurevi project in Claude Code and gave it a detailed prompt to redesign the website. But I didn’t want to micromanage every design decision. So, I gave Claude Code (running Opus 5.5) complete creative freedom to approach the project like an experienced frontend developer and UI/UX designer.

My prompt focused on several areas, including improving the perfume photography, refining the visual hierarchy, polishing animations, fixing inconsistent spacing, and making the overall shopping experience more premium.

I also instructed Claude Code to preserve existing functionality, including the fragrance quiz, product catalog, discovery sets, and checkout flow.

Most importantly, I asked it to analyze the existing codebase before making changes and thoroughly test everything after. I wanted a meaningful redesign, not just a few cosmetic tweaks. Now, let’s see how Claude Code handled the challenge.

Claude Code took a different approach

The small details made a difference

I must say, Claude Code exceeded my expectations here. Instead of making a few cosmetic changes, it completely reimagined Aurevi’s visual identity while retaining the foundation built by Google Antigravity. It replaced the saturated purple, cyan, and pink colors with warm paper tones, rich ink shades, and subtle brass accents.

The combination of Instrument Serif for headlines and Jost for body text gave the website a sophisticated personality. The homepage received an impressive makeover. The hero section now adapts its background to match the featured perfume image.

It creates a seamless visual experience. It also cycles through four fragrances with subtle animations. But Claude didn’t stop at appearances. It redesigned product cards, navigation menus, search, and the shopping cart.

The product pages gained image galleries, fragrance timelines, longevity meters, and a sticky mobile add-to-bag button. Even the fragrance quiz became interactive, with mood-based visuals and personalized recommendations. Claude fixed several responsiveness and accessibility issues, too.

Overall, Claude Code didn’t just redesign Aurevi. It took Antigravity’s already impressive build to an entirely different level.

Gemini started it; Claude finished it

This experiment made me realize that I don’t necessarily need to rely on a single AI coding agent for an entire project. Gemini in Antigravity did the heavy lifting by building Aurevi from scratch, while Claude Code gave me an opportunity to refine the existing foundation.

The best part is that I consumed only around 35% of my session usage. This is a major advantage, especially if you are working with usage limits. Going forward, I can see myself using Antigravity for initial development and bringing Claude Code in for the finishing touches.
