Clerk Has a Free Authentication Platform — Beautiful Sign-In UI Out of the Box

Building auth UI is painful. Email/password, OAuth buttons, magic links, MFA - getting it right takes weeks. Getting it secure takes months.

Clerk is an authentication platform with pre-built, beautiful sign-in components. Drop in a component, get production-ready auth.

What Clerk Offers for Free

  • 10,000 MAUs - Free for up to 10,000 monthly active users
  • Pre-Built UI - Sign-in, sign-up, user profile components
  • Social Login - Google, GitHub, Discord, Apple, Microsoft
  • Magic Links - Passwordless email login
  • MFA - TOTP, SMS, backup codes
  • Organizations - Multi-tenant support
  • Webhooks - User lifecycle events
  • React/Next.js - First-class React support

Quick Start

npm install @clerk/nextjs
Enter fullscreen mode Exit fullscreen mode
// app/layout.tsx
import { ClerkProvider, SignInButton, UserButton } from '@clerk/nextjs'
export default function Layout({ children }) {
  return (
    <ClerkProvider>
      <SignInButton />
      <UserButton />
      {children}
    </ClerkProvider>
  )
}
Enter fullscreen mode Exit fullscreen mode

That is it. Full auth with beautiful UI in 5 lines.
