Show HN: Basecoat – shadcn/UI components, no React required

Basecoat ports the upcoming shadcn/ui v4 [1] to plain HTML + Tailwind (no React):

- Live demo & documentation: https://basecoatui.com

- MIT‑licensed and free: https://github.com/hunvreus/basecoat/

- Works with any backend (Flask, Django, Rails, PHP, etc.) or static site.

- Fully theme‑compatible with shadcn/ui [2].

- Uses a sliver of Alpine.js only for a few interactive bits (e.g. combobox). Swap in your own JS if you prefer.

- Dead simple to use, just drop in a class here and there:

  <button class="btn" data-tooltip="This is a tooltip text">Click me</button>
Why I built it: after moving from a Next.js stack back to Flask + Tailwind + HTMX, I missed shadcn/ui and didn’t want walls of Tailwind classes (like Flowbite or Preline).

Feedback is most welcome: bugs, requests for components, criticism.

Very cool! Are you manually porting all components or are you using some sort of automated process?

All manual. It was a bit of work at first, but mostly because I had to decide how to structure them. It's actually quite straightforward to extend and maintain now.
