Hey Vercel community! :waving_hand: 

I’m **Jessin**, and I’m excited to share something I’ve been building - [NexUI](https://nexui.dev/), an open-source UI component library for `React` built on the `shadcn/ui` copy-paste philosophy.

**The best part? The entire thing was built using** [`v0.app`](https://v0.dev/)**.** From the component designs to the landing page - `v0` was the backbone of the whole build. It’s honestly a testament to how powerful Vercel’s AI tooling has become for shipping real products fast.

## What is NexUI?

NexUI is a collection of 50+ hand-crafted, accessible UI components built with pure `Tailwind CSS` and `React` - no package to install, no lock-in, no hidden wrappers.

* **0 KB bundle size** — you copy the code, it lives in your project
* **100% yours to edit** — plain `TypeScript` + `Tailwind CSS`, no abstractions
* **MIT licensed** — open source forever
* **CLI support** — `npx nexui@latest add button` drops the component straight into your codebase

## Why NexUI?

Inspired by `shadcn/ui`’s philosophy - you own every line. Browse a component on [nexui.dev](https://nexui.dev/), copy it, paste it, ship it. No `npm` installs, no version conflicts, no runtime dependencies.

Works with:

* `Next.js`
* `Vite`
* `Remix`
* `Astro`
* `React Router v7`
* `TanStack Start`
