About
Clerk is a modern authentication and user management platform built specifically for developer experience. It provides pre-built, beautifully designed UI components — <SignIn>, <SignUp>, <UserProfile>, <OrganizationSwitcher> — that render natively in React, Next.js, Vue, Remix, and Svelte, reducing authentication from days of work to under an hour.
Multi-tenancy is a first-class feature: the <OrganizationSwitcher> component manages teams, invitations, and role-based access control without any custom code — ideal for SaaS applications. Passkey and WebAuthn support enables biometric authentication (Face ID, fingerprint) on supported devices. The Account Portal provides a self-service user profile page with no custom implementation required.
Backend SDKs (Node.js, Python, Go, and more) expose the user's identity server-side for protecting API routes. All user data is stored in Clerk's managed infrastructure, with no database table or schema to maintain. The free tier supports 10,000 monthly active users; paid plans scale to unlimited users with advanced organisation features.
