Modern authentication and user management platform with pre‑built UI components, multi‑factor auth, and social logins. Free tier includes 5,000 monthly active users.
Clerk is an authentication platform with pre‑built UI components (sign‑in, sign‑up, user profile). Integrate in minutes with Next.js, React Native, Svelte, etc. It also includes organization management and invitations.
I integrated Clerk into a Next.js app. Adding <SignIn /> and <UserButton /> gave me a complete auth flow. User profiles, session management, and security were handled automatically. What would have taken days took 30 minutes.
Clerk’s UI components are beautiful and customizable, letting you focus on your product instead of reinventing auth.
Pro tip: Clerk supports custom JWT templates, so you can pass user info to backends like Supabase or Hasura. The 5,000 MAU free tier is plenty for most personal projects.
