In plain words
Basecoat is a component library that brings shadcn/UI design patterns to plain HTML and Tailwind CSS without requiring React. It works with any backend framework like Flask, Django, or Rails, as well as static sites. The components are theme-compatible with shadcn/UI and use minimal Alpine.js only for interactive elements like comboboxes, which can be replaced with custom JavaScript. It is free and MIT-licensed, designed for developers who want clean, styled components without heavy JavaScript frameworks.

In the maker’s words, at launch
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. [1]: https://v4.shadcn.com/ [2]: https://basecoatui.com/installation/#install-theming [3]: https://pagescms.org
