Clerk vs Auth0: A detailed breakdown of the modern challenger versus the enterprise standard. Which auth provider is best for your React/Next.js app?

## Frequently Asked Questions

Yes, Clerk has a very generous free tier allowing up to 10,000 Monthly Active Users (MAUs), which is enough for most startups to get significant traction.

### Does Auth0 work with Next.js?

### Can I use Clerk for mobile apps?

Yes, Clerk has SDKs for React Native and Expo, making it a great choice for cross-platform applications.

### Which is better for B2B SaaS?

Clerk is generally considered better for modern B2B SaaS because its 'Organizations' feature is core to the product, allowing you to easily build features like 'Invite Member', 'Role Management', and 'Switch Workspace' with pre-built components.
