"I can build my website in Claude Chat, when would I need Claude Code?"

This is one of the most common Claude Chat vs Claude Code questions I hear in my workshops.

The short answer: building a website in Claude Chat is like building a temporary shelter and living in it as your home. It keeps the rain off for a while, but it was never built to last, or to host anyone else.

It works, until it doesn’t.

And it is often followed by another learner’s comment: “My website works in Claude Chat, but some features stop working once I publish it to a custom domain.”

That second comment is the answer to the first. Claude Chat’s Artifacts got powerful enough to build and serve a static website, so the line between the two tools got blurry for non-techies. But under the hood, there is a huge difference.

Two limits decide where Claude Chat stops.

1. It only does static websites out of the box.

The moment you need a server, form submission, a database, or a secret API key, it works around the problem with a quick hack instead of solving it.

To test it, I asked Claude Chat to build a website with a contact form that emails me when a visitor submits it. Here is what it gave me. It asks me to paste my Resend API key into a banner, stores it in the browser’s localStorage, and POSTs straight to the email API from the client. It even tells me to “drop index.html anywhere, no server needed.”

That works on my own browser, because that is where I entered the key. And for it to work for my visitors, I would need to send them my secret key too.

2. There is limited context in a chat session.

Your website lives in the chat history, not in proper files with version control. Every time you ask Claude Chat to update the site, the context window fills up. At some point you hit the chat’s limit and cannot keep working on the site without starting a new chat. And since that conversation was your only record of how the site was built, starting fresh means losing it.

You can stretch past both limits. Add a connector to Cloudflare or another host, and wire in external services for the server-side parts. But by the time you have done all that, you have built a more complicated, more fragile version of what Claude Code does properly out of the box.

You spend your effort working around the tool instead of learning the tool.

If you just want a quick static page, Claude Chat is fine. If you are a business professional who wants to build something real, something with a backend that still works after you publish and share it, the proper tool is Claude Code.

If you want to learn the foundation of building and shipping your own website, I run a Foundations of Claude Code workshop. The 18 June cohort is full. The next two with openings are 2 July and 16 July.
