What is Claude Code, and why it matters for site builds

Most people still pay thousands for a marketing site. Inside Claude Code, you can get a fully animated site started with three simple setups. And the last one is the big game changer.

A typical marketing site from an agency or freelancer will run you anywhere from $3,000 to $15,000 once you factor in design, custom animations, revisions, and the back and forth. That is not an exaggeration. Even a basic five-page site with a hero section, a pricing table, a feature grid, and a footer can eat up weeks and a thick invoice. None of that is necessary anymore. If you are willing to spend 30 minutes with Claude Code and three specific additions, you can have a fully animated, professional-looking marketing page up and running without touching the traditional web dev pipeline.

Here is exactly how that works, step by step, with the real commands and the one shortcut that makes everything click.

What is Claude Code, and why it matters for site builds

Claude Code is Anthropic’s agentic coding tool. You type what you want, it writes and runs code inside a terminal, installs dependencies, sets up a project, and spits out a working app or site. It can scaffold a Next.js project, spin up Tailwind, drop in components, and even handle deployment if you guide it. The barrier used to be that you still needed to describe every pixel, every animation, every layout decision in painstaking detail. That led to generic “AI slop” sites, bland, unpolished, and instantly recognizable as bot-made. The three setups below fix that.

Setup 1: Framer Motion, the animation backbone

First, install Framer Motion. If you are not technical, Framer Motion is essentially the animation library for React-based sites. It handles fades, slides, hover effects, page transitions, scroll-triggered reveals, and the kind of motion that makes a page feel premium. Without it, you get static blocks of text and images. With it, everything comes alive.

The install is a single command inside your Claude Code session:

npm install framer-motion

Once that is in your project, you can ask Claude Code to add enter animations to your hero, stagger your feature cards, animate your CTA button on hover, or build a smooth page transition between routes. The library is extremely well documented, so Claude Code rarely hallucinates on it. The animations look native, not hacked together.

Still, animation alone does not make a site look good. You need a design direction. That is where the second setup comes in.

Setup 2: The UI/UX Pro Max skill, killing AI slop

A skill inside Claude Code is like a plugin that teaches the model how to behave in a specific domain. The UI/UX Pro Max skill is built specifically for design quality. It tunes the model’s output so you get better layout choices, proper spacing, real typographic hierarchy, and coherent color palettes. In short, your site no longer looks like AI slop.

When you install this skill, Claude Code stops giving you that generic startup-template look, the 200px hero text, the default gray backgrounds, the mismatched padding. Instead, it starts leaning into design principles: breathing room between sections, consistent line heights, contrast ratios that actually pass accessibility, and button styles that feel intentional. The skill pushes the model to think like a designer, not just a code generator.

To install it, you can run something like:

claude skill install ui-ux-pro-max

From that point on, every prompt you write gets filtered through that design lens. You do not have to specify “make it look premium” twenty times. The base aesthetic shifts. It is not perfect, but it solves about 70% of the visual problems that plague AI-generated pages.

Now you have motion and design sense. But there is still a massive time sink: you have to describe everything from scratch.

The catch: describing everything from scratch still kills your speed

Even with Framer Motion installed and the UI/UX Pro Max skill active, you are still the one writing the prompts. You have to spell out what the hero section looks like, what the pricing table should contain, how the feature grid should animate, what copy goes in the footer, how the mobile breakpoints should collapse. That means typing out long, precise descriptions for every single block of the page. If you have ever tried to explain a nav bar to an AI in plain English, you know it can take ten minutes of corrections just to get the dropdown behavior right.

Multiply that by eight or ten sections per page, and you are back to spending hours on a site. You save money, maybe, but you lose time. And time is the whole point of using an AI agent, speed.

That is where the third setup changes everything.

Setup 3: 21st.dev, the component library that is the real shortcut

21st.dev is a library of already designed, already animated components that plug directly into your Claude Code session. You pick the section you want, a hero, a pricing table, a feature comparison grid, a testimonial carousel, a footer, and you copy a single command. Paste that command into Claude Code. The component drops into your project fully styled, fully animated, and fully responsive. No prompt engineering. No back and forth. Just one paste and it is there.

The components are hand-crafted, not generated on the fly. That means the spacing is consistent, the motion is tasteful, and the dark mode support is built in. They use Framer Motion under the hood, so you are not losing any of the animation quality. And because the design sense is baked in from the start, you do not need to keep tweaking the UI/UX Pro Max skill outputs to fix small details. The library handles it.

Here is how it looks in practice: you open 21st.dev in your browser, browse to the “Hero Sections” category, find one you like, and see a command like:

npx 21st add hero-centered-gradient

You copy that, paste it into your Claude Code terminal, and within seconds you have a hero section with a gradient background, a headline, a subheading, a CTA button, and a subtle scroll animation, all in your project. You do the same for the pricing table:

npx 21st add pricing-three-tiers

And for the footer:

npx 21st add footer-links-dark

Three commands, three sections, zero descriptions. The component drops straight into your existing layout with all the necessary imports, dependencies, and styles. You can then customize the copy, swap out the images, and adjust the colors if you want. But the heavy lifting is done.

This removes the biggest bottleneck: turning a design vision into actual, working UI. With 21st.dev, the vision is already there. You just pick what you want.

The full install order and how to use all three together

If you are starting from scratch inside Claude Code, here is the exact sequence that gets you from nothing to a fully animated, professional marketing site:

  1. Initialize your project. Tell Claude Code to set up a Next.js project with Tailwind CSS. One sentence is enough. Claude handles everything, folder structure, config files, dev server.
  2. Install Framer Motion. Run npm install framer-motion. This gives you the animation engine.
  3. Install the UI/UX Pro Max skill. Run claude skill install ui-ux-pro-max. This upgrades the design output. Now your prompts produce better-looking code.
  4. Open 21st.dev. Pick your first component, usually the hero. Copy the command, paste it into Claude Code. Watch it land.
  5. Keep stacking. Add your pricing table, features, testimonials, footer, each with a single paste from 21st.dev. The components are modular, so they do not conflict.
  6. Customize the copy and images. Claude Code can help you swap in your own text, logos, and photos. It understands the existing code and can make precise edits.
  7. Deploy. Ask Claude Code to push to Vercel or Netlify. It will walk you through the steps.

This entire process, from empty terminal to live, animated site, can be done in 30 to 45 minutes. No design handoff. No developer sprints. No invoices.

Why this combination actually works (and what most people get wrong)

The reason these three setups click is that they each solve a different layer of the problem. Framer Motion handles motion. UI/UX Pro Max handles taste. 21st.dev handles structure and speed. Individually, each one is helpful. Together, they eliminate the need for design skills, animation skills, and the patience to describe UI components line by line.

A lot of people try to build sites with Claude Code and stop after the first step. They install Framer Motion and then spend hours prompting for a hero that still looks off. They miss the skill that fixes the design output, and they definitely miss the component library that makes the whole process five times faster. Then they conclude that AI-generated sites still are not ready. They are wrong. They just did not have the full stack.

I have seen marketers launch a full landing page in a single evening, something that would have taken their usual agency two weeks and a $5,000 minimum engagement. The difference was not that they were technical. They were not. The difference was they followed the right install order and used the shortcut.

The component library is the big game changer

There is no way around it. The first two setups, Framer Motion and UI/UX Pro Max, are essential, but they are table stakes. They get you from zero to decent. 21st.dev gets you from decent to done in minutes. That is the moment where the process stops feeling like coding and starts feeling like assembling a site with building blocks. You stop describing and start dropping in.

And because the components are already animated, you do not have to prompt for “fade in on scroll” or “make the button pulse on hover.” That motion is already part of the component. You get a premium feel without a single animation prompt.

The shift in speed is absurd. A pricing table that would take ten minutes of prompting now takes ten seconds. A testimonial carousel that would require you to reason about autoplay, navigation arrows, and responsive breakpoints just appears fully functional. The heavy cognitive load of UI construction is gone.

That is why this setup is the first one I recommend now for anyone who wants a real marketing site without paying real marketing-site money. The barrier is gone.
