Basecoat – shadcn/UI components, no React required

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 a nutshell: Basecoat is a port of shadcn/ui to HTML and Tailwind CSS. It's a modern, themeable component library; everything from buttons to comboboxes and dialogs. Why? Well, I got sick of React and moved over to a more "old school" stack (Python, HTMX, Alpine.js and Tailwind). The one thing I missed was shadcn/ui [1]. Nice defaults, well thought out design system, easy to theme and great to build your own component library with. I didn't find the alternatives compelling: Flowbite, Preline and the likes encourage you to copy/paste dozens of classes for each element. That's…

  I originally built this app to organize and reuse interesting React + Tailwind components I came across on Twitter, inspired by the shadcn/ui approach. Later, a friend started contributing their own components, and it got me thinking—this could grow into something bigger, like an NPM for design engineers to share and use components. Would love to hear your thoughts!

  Shadcn/UI theme editor – Design and share Shadcn themesOct 2025 · shadcnthemer.com · ▲136

  Hey, I built https://ShadcnThemer.com - a web app for creating and sharing themes for shadcn/ui, made with my some of my favorites, Next.js 15, Tailwind CSS 4, Drizzle ORM, and Supabase. The goal was to make it easy to visually design shadcn color themes, preview them live across various example UIs, and export them straight into your projects (as CSS or via the shadcn CLI registry command). I had a bit of experience going into this because I built the Theme Studio for VS Code in the past, but it was fun using a modern stack and leveraging Cursor to help me along the way this…

  Talanoa▲340

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  Tapflow 2.0▲1,125

  We built Tapflow for devs, designers, PMs, and tech folks who’ve been sitting on internal docs, templates, and systems — but never productized them. Upload a PDF, notes, or workshop deck, and Tapflow drafts a structured product (with chapters, teaser and pricing plans). It’s good for AI kits, onboarding guides, design systems, and frameworks. You can sell through Stripe, LemonSqueezy, or PayPal. Real-time collaboration is in early beta. No site builder, no LMS — clean design and just focused tools to ship. Fully bootstrapped and just launched on PH today →…
