## What it is
The official monorepo of Clerk's JavaScript SDKs under the @clerk namespace, providing authentication and user management for frameworks like Next.js, React, Vue, Nuxt, Expo, Astro, and Express. It offers drop-in UI components for sign-up, sign-in, profile management, multi-tenancy organizations, and billing backed by the Clerk platform.

## Use cases
- add sign-up and sign-in to a Next.js app
- manage user profiles and sessions in React
- implement multi-tenant organizations with membership switching
- add JWT-based auth to an Express or Fastify API
- build authentication for a React Native Expo app
- add social login and MFA without building UI from scratch

## When to choose
- you want hosted, drop-in auth UI with minimal setup
- your stack is Next.js, React, Vue, Nuxt, Expo, or another supported JS framework
- you need organizations/multi-tenancy and user management out of the box

## When to avoid
- you need fully self-hosted auth with no external service dependency
- you require full control over the auth data store and custom flows beyond Clerk's model
- your project is not JavaScript/TypeScript
