Authentication

Clerk vs Auth0

Modern developer-first auth vs the enterprise identity platform. One gets you shipping in minutes, the other handles every edge case. Here's the breakdown.

⚑ Our Verdict

Clerk wins for developer experience.

If you're building a modern web app with React or Next.js, Clerk's pre-built components and simple API get you to production in minutes, not days. Auth0 is the safer bet for complex enterprise requirements and multi-platform identity management.

🎯 Our Recommendation

For most modern web apps, Clerk is the better choice. The developer experience is in a different league, drop-in <SignIn/> components, automatic session management, and a gorgeous user management dashboard. Auth0 is still the right pick for enterprises with complex identity requirements, multi-platform apps, or strict compliance needs. But if you're building a SaaS with React or Next.js, Clerk gets you there 10x faster.

Frequently Asked Questions

Is Clerk better than Auth0 for new projects?

For most modern web apps, yes. Clerk offers pre-built UI components, better React/Next.js integration, and a dramatically simpler setup. You can have authentication working in under 10 minutes. Auth0 is more flexible but requires significantly more configuration and offers a steeper learning curve.

How does Clerk pricing compare to Auth0?

Clerk is free for up to 10,000 monthly active users, then $0.02/MAU. Auth0 offers a free tier of 25,000 MAU but with limited features, paid plans start at $35/mo. At scale, Auth0 can get expensive quickly, especially for enterprise features.

Does Clerk support enterprise SSO?

Yes. Clerk supports SAML SSO, OIDC, and enterprise connections on its Pro plan. Auth0 also supports enterprise SSO and has been doing it longer, making it slightly more battle-tested for complex enterprise identity scenarios.

Can I migrate from Auth0 to Clerk?

Yes. Clerk provides migration guides and tools to import users from Auth0. Password hashes can be transferred so users don't need to reset passwords. The migration typically takes a few hours for most applications.

Which has better React and Next.js support?

Clerk, by a wide margin. It was built React-first with components like <SignIn/>, <UserButton/>, and <OrganizationSwitcher/> that drop right into your app. Auth0's React SDK works but requires more manual UI work and configuration.
