Clerk Has a Free Auth Platform: Drop-In Authentication With Pre-Built UI Components and 10K Free MAUs

Building auth from scratch takes weeks — sign up, sign in, password reset, email verification, OAuth, session management, user profiles. Auth0 and Firebase Auth work but give you ugly default UIs. What if auth was a React component you dropped in — beautiful by default, fully customizable, free for 10,000 users? That's Clerk.
