What is Clerk?
Why look for Clerk alternatives?
Clerk pricing is based on monthly active users and can become expensive at scale. It is primarily designed for web applications and its mobile SDK support is less mature than Auth0. Teams with complex enterprise SSO requirements or large user bases sometimes find Auth0 or a self-hosted solution more cost-effective.

Frequently asked
Is Clerk free?

Why do Next.js developers prefer Clerk?
Clerk has first-class Next.js integration including middleware helpers, server component utilities, and App Router support. The pre-built components match modern design expectations and the setup takes minutes rather than hours compared to alternatives.

Yes. Clerk has a built-in organizations feature for B2B SaaS products, supporting multiple members per organization, role-based access, and organization invitations. This covers the multi-tenant authentication pattern without custom code.
How does Clerk handle session management?
Clerk manages sessions server-side and uses short-lived JWTs on the client. Sessions can be revoked instantly, which is more secure than traditional JWT-only approaches where tokens remain valid until expiry.
