Introduction
Generating a website from a prompt works well for a first draft and badly for a tenth page. The break points are consistent: content structure, repeat consistency, responsive edge cases and performance. A template solves those before you start, which is why the two approaches suit different jobs.
We build templates, so read this with that in mind. We also use AI to build every day, and the honest position is not that one replaces the other.
What Vibecoding Genuinely Does Well
Starting. A blank canvas is the expensive part of a website and a prompt clears it in seconds. For a landing page, a one off microsite, or proving a layout idea before committing, generating it is simply faster than anything else available.
It is also good at variation. Ask for five hero treatments and you get five, which is a genuinely useful way to find a direction you would not have drawn yourself.
Where It Breaks
The failures are not usually visual. They show up in structure, and they show up later, which is what makes them expensive.
Generated from a prompt | Built on a template |
|---|---|
First page looks finished in minutes | First page takes longer to make yours |
Page ten rarely matches page one | Page ten is the same components as page one |
Content usually hardcoded into the layout | Content modelled in a CMS from the start |
Breakpoints handled inconsistently | Breakpoints already designed and tested |
The Content Structure Problem
This is the big one. Generated pages tend to bake text and images directly into the layout, because that is what the prompt asked for; a page. Nothing models the difference between a blog post and a case study, so nothing can list, filter or sort them later.
You do not feel this at page one. You feel it when someone asks for a related posts section, or a category filter, and the answer is that every page has to be rebuilt because there is no collection underneath any of it.
The Tenth Page Problem
Prompt driven pages drift. Spacing moves a few pixels, a heading changes weight, a button gets a slightly different radius, and none of it is wrong in isolation. Stacked across ten pages it reads as an amateur site even when every single page looks fine on its own.
Components are what stops that, because the second page reuses the first rather than reinterpreting it. This is unglamorous and it is most of what a design system actually buys you.
Responsive and Performance
Desktop is almost always right. The edge cases are where it slips; long words in narrow columns, tall content pushing a fixed element, the awkward width between tablet and phone. These are tested rather than reasoned about, and generation does not test.
Performance is the quieter cost. Generated markup occassionally carries oversized images, unused effects and stacked wrappers, and none of that announces itself until someone runs a page speed report on the live site.
When to Vibecode Anyway
If the site is one page, short lived, or a test, generate it. The structure problems all cost you at scale and there is no scale here; the speed is a pure win and the tradeoff never arrives.
The moment content repeats, or more than one person will maintain it, the calculation flips. Then you want something with a CMS and components already in place, whether that is a template or a system you built yourself.
Before You Choose
Ask one question: how many pages will this have in a year, and who edits them. If the answer is one page and one person, prompt it. If it is thirty pages and a team, start from something structured; the time you save in week one is not worth what it cost in month six.
None of this means keeping agents out of the project. We drive this site from one, as described in How to Edit a Framer Site with Claude Code; the difference is that it works inside a structure somebody designed.
