Clerk shadcn Registry

shadcn CLI commands that scaffold Clerk auth pages and middleware into a Next.js app

Tier A · StrongRegistryBlock CollectionReferenceclerk.com

Clerk's docs page for its shadcn-compatible registry, plus the registry itself at clerk.com/r. Twelve items are published: a full quickstart block, a sign-in-or-up variant, sign-in / sign-up / waitlist pages, a ClerkProvider wrapper, a theme provider, a header with auth buttons, a layout-with-header, the Clerk middleware file, and two multistep onboarding flows (AIO and custom-flows). Everything targets the Next.js App Router only — there are no React Router, Vue or Remix items.

Install

npx shadcn@latest add https://clerk.com/r/nextjs-quickstart.json

For an agent

This is the fastest correct path from an empty Next.js app to working auth: run the nextjs-quickstart item and it drops ClerkProvider, middleware, a header and the sign-in/sign-up routes in one shot, instead of you hand-writing matchers in middleware.ts and getting the public-route regex wrong. Pair it with the Supabase UI blocks only if Supabase is the database and Clerk is the identity provider — do not install both auth blocks or you get two competing session layers. The registry stops at Next.js App Router, so for Vite, React Router or Remix fall back to Clerk's normal SDK docs.

Why it is here. A vendor proving that auth setup — the most error-prone part of a scaffold — can be one shadcn command, which is exactly the shape an agent can execute reliably.
