Show HN: Basecoat – shadcn/UI components, no React required
25 hunvreus 11 5/13/2025, 11:22:40 AM
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.

One suggestion would be adding a focus trap, such as when a Dialog opens. It's nice to use the tab key to move around the Dialog (inputs and buttons). Currently focus leaves to the page behind. It might be as simple as adding https://alpinejs.dev/plugins/focus#x-trap
Also, reminds me of https://franken-ui.dev
I think it may be on the heavier side though (~100k).
