Clerk is the modern auth-of-choice for Next.js apps. UI components, server-side helpers, and great organization-aware multi-tenancy.

Why together · 01
Why this combo works.
Clerk's middleware handles protected routes, the React SDK provides drop-in <SignIn /> and <UserButton />, and server-side auth() works in server actions and route handlers.
Setup
Wrap the app in <ClerkProvider>, add middleware.ts to protect routes, and use auth() in server components.
Gotchas
- Free tier has user limits — plan accordingly
