Claude can build a website, and you can open the two it built for us right now. We gave Claude Opus 5.5 and Claude Fable 5.1 the same brief, a marketing site for a fictional scheduling app called Driftwood, and let each work once in Claude Code with no human edits. Both delivered a complete, working site. They just disagree on what a good one looks like.
What did Claude actually build?
Two full one-page sites, each a single HTML file. Both have a hero, testimonials, features, a pricing table with a working monthly-to-yearly switch, an FAQ and a footer, as the brief required. Neither logged a runtime error during our recording.
- Opus 5.5 led with "Easy to book. Hard to interrupt." and put a working booking calendar in the hero, then added a sign-up dialog nobody asked for. It set the page in Fraunces and Geist and ran for 43 minutes.
- Fable 5.1 led with "Get booked without giving up your best hours." in Instrument Serif, and animated a little cursor that books and pays for a $180 session in the hero. It ran for 28 minutes.
How do you use Claude as a website builder?
Two routes, depending on how much you want to own. In the Claude app, ask for a single-page site and Claude renders it as an Artifact you can preview and download; that works on the free plan. With Claude Code, Claude writes the files into a folder, opens the page in a browser and fixes what it sees, which is how both builds here were made. Claude Code needs a paid plan, from $17 a month billed annually according to Claude's pricing page.
Whichever route you take, write the brief the way ours is written: the product, the sections, the facts and prices you want on the page, and the constraint that it must work on a phone. The full Driftwood prompt is public if you want a template.
Which Claude should you pick?
Start with Opus 5.5. It built the richer site, and at $4 per million input tokens and $20 per million output tokens it is the cheaper of the two; Anthropic's own model guide recommends it for most workloads. Reach for Fable 5.1, at $10 and $50, when you want a quieter, more editorial page or a long, demanding build. My read of the two sites: Opus designs like a product team, Fable like a magazine.
See if you can spot the Claude sites without labels: four builds, names hidden.
Take the blind testIs a Claude-built site ready to publish?
Almost. Both files can go on any static host as they are. What they cannot do yet is take a booking or a sign-up for real, because the brief allowed no network requests, so the forms are demonstrations. Plan for a form service and a domain, and check the phone layout in the live build before you ship. To see how GPT models handled the same brief, read ChatGPT as a website builder.
Frequently asked questions
Can Claude build a whole website by itself?
From one prompt, yes. Claude Opus 5.5 and Claude Fable 5.1 each produced a complete one-page marketing site, with working pricing, FAQ and phone menu, without any human edits. A multi-page site with a backend is a bigger job that needs several sessions and a host.
Do I need Claude Code to build a website with Claude?
No. The free Claude app can create a page as an Artifact you can preview. Claude Code, which comes with the Pro plan from $17 a month billed annually, writes real files on your computer and can test its own page, which is how both builds here were made.
Which Claude model is best for building websites?
Opus 5.5 built the more feature-rich site and costs less per token; Fable 5.1 built a calmer, more editorial site in about two thirds of the time. For most websites Opus 5.5 is the better default, and Anthropic's own model guide recommends starting there.
Is Claude better than ChatGPT for building websites?
On our brief the Claude sites were more distinctive and took longer, while the two GPT sites were faster and looked alike. Watch all four side by side and run the blind test rather than trusting a summary.
