## The Hook

Clerk solves auth completely—not just the backend, but the actual forms.

## What's Good

Integration with Next.js is exceptional: middleware handles route protection, hooks provide user state, and Server Components work seamlessly. Multi-factor authentication, social logins, and organization management are included.

## The Catch

Loud Catch: Clerk is a paid auth product with a free tier that evaporates as MAUs grow. You are outsourcing login UI and session logic; customization is the Clerk way or a fight. This is not the OSS auth library.

## Verdict

Auth-as-a-feature ships faster than auth-as-a-library.
