How to use Claude models to build a website
Updated July 18, 2026
Build with Claude Code — the agentic tool that reads and writes your files, runs commands and verifies its own work in a browser — not by pasting snippets from a chat window. Reach for the most capable model (Claude Opus 4.8) for architecture and the tricky motion, and a fast model (Claude Haiku 4.5) for mechanical edits like renames and copy tweaks.
The model matters less than the loop: give it a concrete spec and real assets, let it scaffold, build one section at a time, and verify each in the browser before moving on. Every template in this studio was built exactly this way.
Claude Code vs. the chat window
For building a whole site, use Claude Code — Anthropic's agentic coding tool, available in the terminal, the desktop and web apps, and as VS Code and JetBrains extensions. Unlike a chat window, it edits files directly, runs your dev server, reads the console, takes screenshots and fixes what it sees. That verify-and-iterate loop is what turns a prompt into a shipped page.
Use the raw Claude API only when you're embedding Claude inside your own product (a generative feature, an agent). For building the site itself, Claude Code is the right tool.
Picking a model
Claude Opus 4.8 is the most capable model — use it for the parts that need judgement: the architecture, the scroll-scrub logic, debugging a stubborn layout, or anything where being wrong costs an hour. Claude Sonnet is the balanced middle. Claude Haiku 4.5 is fast and cheap — perfect for mechanical work like renaming variables, adjusting copy, or wiring config once the hard thinking is done.
A good habit: start on the strongest model to get the structure and motion right, then drop to a faster one for the long tail of small edits. On Claude Code you can switch models mid-session, and Fast mode keeps Opus responsive for quick back-and-forth.
A workflow that ships
Plan first: have the model lay out the sections and the motion before it writes anything. Then scaffold the Next.js app, and build one section at a time — hero, then the next, verifying each in the browser. Keep everything config-driven (brand, copy, media paths in one file) so the site re-skins without touching components.
Give it real inputs. A concrete brief ('a cruise site where scroll flies you from the clouds to a dinner at sea') and actual assets (a video, some photos) produce dramatically better results than 'make me a nice site'. When an asset is missing, have it render a labelled placeholder so the layout and motion still read.
Getting output you can trust
Be specific about the stack and the effects, hand over a reference, and make the model verify — run the page, check the console, screenshot it, fix what's wrong. Commit often so you can always roll back. The result isn't a lucky one-shot; it's a tested build you watched come together. That's the difference between the free prompt and the paid, tested download of any template here.
Frequently asked
What is Claude Code?
Claude Code is Anthropic's agentic coding tool. It runs in the terminal, the desktop and web apps, and in VS Code and JetBrains, and it edits files, runs commands, reads the console and verifies its work in a browser — so it can build and debug a whole site, not just suggest snippets.
Which Claude model is best for building websites?
Use the most capable model, Claude Opus 4.8, for architecture and complex motion, and a fast model like Claude Haiku 4.5 for mechanical edits. Claude Sonnet is a balanced middle. Switching models mid-build is normal.
Should I use the Claude API or Claude Code to build a site?
Claude Code, for building the site itself — it edits files and verifies in the browser. Use the Claude API when you're embedding Claude inside your own product, like a generative feature or an agent.
