✦ THE OPEN EXPERIMENT / 2026

Can AI clone any website from just a URL?

We gave coding agents real websites to rebuild. Here are the original prompts, visual evidence, source code, and the parts they couldn't reproduce.

01 / THE EXPERIMENTS

Four builds. Three real challenges.

Select an experiment to inspect desktop/mobile screenshots, original prompts, working features, and known limitations.

      02 / HEAD TO HEAD

      One Apple page. Two AI agents.

      Codex and Claude Code independently attempted the same iPhone 18 Pro page using the website-cloning skill. Both documented their work and limitations.

      3D/AR and exact scroll animation timing are not reproduced. Film playback needs Apple online.

      ✳

      Unlabeled raw Claude testing evidence screenshot

      Videos play when in view rather than following scroll frame-by-frame. 3D/AR isn't reproduced.

      Codex has labeled paired source/clone screenshots. Claude's raw captures do not reliably label each browser tab. No numeric accuracy score is claimed without measurement.

      03 / METHOD

      Evidence over hype.

      Getting a successful build is not the same as accurately reproducing a website. We document both the results and the gaps.

      01

      Inspect

      Study original pages on desktop and mobile, including menus, assets and scroll states.

      02

      Rebuild

      Produce editable code, not a screenshot embedded as a finished website.

      03

      Compare

      Examine matched screenshots and exercise interaction states when evidence is available.

      04

      Disclose

      Document missing 3D, approximation of animations, external links and server-side features.
