What is Clerk?

Clerk is a modern authentication and user management platform for web applications. It provides pre-built, customizable UI components for sign-up, sign-in, and user profiles that drop into React and Next.js apps. AI features include intelligent fraud detection, adaptive session management, and bot protection. The platform handles the full auth lifecycle — social logins, multi-factor auth, passwordless, organization management, and role-based access.
