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.

Really great! A major downside of moving from SPA's back to vanilla JS is how much you lose in terms of UI components.

I've normally done DaisyUI + Tailwind + Rails but it never feels quite right. Basecoat is a really nice step forward.

I have to imagine the author is planning to charge for a premium package at some point, but given that a huge % of development is spent on UI design, I'd be more than happy to pay for a year of updates.

Glad you like it. Do let me know what you end up building with it.

Same here: I could never quite get into Flowbite, Daisy UI, Preline or any of the other many alternatives.

I did wonder if people would want to buy premium layouts or components. No plan to charge for anything for now though.
