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 time.

Thanks for sharing! What's the difference between your app and tweakcn?

edit: would also love to be able to open preview on new tabs with middle-click.

Tweakcn is a great tool too. Main difference is I'm hoping ShadcnThemer will be more of a community-driven hub for sharing, starring, and forking themes - similar to how color palette websites have 1000's of user-made palettes. (I took this approach when building the Theme Studio for VS Code and it worked really well, 1000's of themes were designed and shared.)

Tweakcn also charges $ users to be able to share and save themes which I think is silly for a tool like this, should be 100% free and open source.

I also prefer the simple UX of ShadcnThemer better but I'm biased of course.
