Clerk offers 5,000 Monthly Active Users free, then $25/month for up to 10,000 MAUs ($0.05 per additional user). This is competitive with Auth0's pricing but includes more features in the base plan like Organizations, multi-session support, and advanced components. Unlike Auth0, there are no separate charges for social logins or basic enterprise features, making it more predictable for growing applications.
Yes, Clerk provides extensive styling options including CSS custom properties, Tailwind CSS classes, and complete theme customization. You can also build custom components using Clerk's headless hooks and primitives while maintaining full control over the UI. The components support dark mode, custom color schemes, and can be styled to match any design system while keeping all the authentication logic intact.
Clerk has first-class Next.js support with server-side authentication checking, middleware protection, and hydration-safe client components. The clerkMiddleware() function runs at the edge to protect routes before rendering, and getAuth() provides server-side access to user data in API routes and server components. This eliminates the authentication flash that's common with client-only auth solutions.
Clerk provides GDPR-compliant data handling with EU data residency options, automatic data deletion workflows, and user data export capabilities. Users can delete their own accounts through the provided components, and you can configure data retention policies. Clerk also supports custom privacy policies and cookie consent management integrated with the authentication flow.
