Introduction

23rd is a shadcn/ui registry of opinionated UI components built for people who ship.

Made by radiumcoders (aka Jay).

What this is

A curated set of components with strong defaults — less boilerplate, clearer decisions, and a look that stays consistent across projects. Install what you need through the shadcn CLI (React or Svelte 5), then customize in your own codebase like any other registry item.

Why opinionated

Most component kits hand you every option. 23rd picks a direction: spacing, radius, interaction patterns, and composition rules that already feel finished. You can still override anything — you just start from a sharper baseline.
