Prime UI
AI site builder, Next.js, Tailwind, no code
TL;DR: Prime UI is an AI-powered website builder that takes you from sitemap to production-ready Next.js and Tailwind CSS code. It ships with 200+ components, built-in SEO, and one-time pricing starting at $99. No prompt engineering required.
What Is Prime UI?
Prime UI is an AI-assisted site builder designed specifically as the foundation for AI-generated websites. You start with a sitemap, let AI handle the layout experimentation, and export real Next.js and Tailwind CSS code that actually works in production.
It's not a drag-and-drop toy or a template marketplace. Prime UI sits in the middle of the process: between "I have an idea" and "I have working code." It handles the boring structural work so you can ship faster without wrestling with prompts or debugging AI slop.
It's built for solo builders and agencies alike, trusted by 1,000+ users including brands like Forbes, Deno, and Dagster.

FAQ
Is Prime UI a one-time purchase or a subscription?
It's a one-time fee. Personal is $99 and Business is $299. No monthly billing.
Does Prime UI work for web apps or just marketing sites?
It's built for marketing sites specifically - landing pages, blogs, docs, and pricing pages. It's not designed for building dashboards, SaaS products, or e-commerce storefronts.
Can I use Prime UI if I don't know how to code?
You can use it to generate and explore layouts without coding, but the output is real Next.js code. Some basic familiarity with web development helps when you go to deploy or customize it.
