v0.dev: Vercel's AI Generates React UIs From Prompts, Designers Getting Nervous

v0.dev is Vercel's answer to "what if we just ask an AI to build our UI?" You describe the interface you want ("a landing page with hero section, feature cards, and footer"), and v0 generates the complete code—Tailwind CSS, Shadcn UI, everything bundled.

The result? Actual React components you can copy-paste straight into your Next.js or React project. We're not talking static HTML here: it generates state management, hooks, animations, responsive design. The whole package.

Here's the sweet part: you can iterate in real-time. "Add a carousel." "Make the button bigger." "Switch the color scheme." v0 gets it and rewires the code accordingly.

The catch? The generated UIs are... generic. They all look vaguely the same—that safe, standardized Tailwind aesthetic. If you need something with personality or actual brand identity, you're digging into the code yourself.

Oh, and v0 gives you a handful of free prompts per day. After that, subscription time: roughly $20/month.

When is it actually useful? Rapid prototyping, MVPs, internal dashboards, admin panels. For consumer product landing pages where design matters? Yeah, hire an actual designer.
