21st Dev is a AI UI Component library that gives you AI prompts to level-up your website designs

Building a professional-looking website used to feel like climbing a mountain. Hours of coding. Endless trial and error. And then… something breaks.

Now there’s an easier way — a tool called 21st.dev. It’s an AI-powered UI components library built for people who love vibe coding with a twist of automation.

Here’s the simple idea: it gives you premium-looking website components that are ready to use. No digging through messy codebases. No confusing setup.

You just go to their site and browse. Think sleek buttons, animated cards, or full-page layouts. Each one looks like a designer spent hours on it.

Once you find something you like, you’ll notice something cool. 21st.dev doesn’t only give you the code. It also shows you the exact AI prompt used to create that component.

The good news? That means you can copy that prompt and drop it straight into your favorite AI builder — Cursor, Lovable, Bolt and VS Code too.

And then… you watch as your AI tool builds the same component instantly. Styled. Functional. Ready to use.

Because here’s the thing — the people behind 21st.dev know what it’s like to get stuck in design details. So they made it simple. Pick, prompt, paste, done.

It’s like walking into a store where everything’s already organized by style, color, and perfection level. You just grab what fits your project and move on.

I tried it last week while rebuilding a landing page. What usually takes me an afternoon? Took less than fifteen minutes.

If you want your site to look clean, modern, and built by a pro — without spending days tweaking pixels — this is where you start.
