tool:Clerk
Clerk is a complete authentication and user management platform for React, Next.js, Expo, and modern JavaScript frameworks. It ships pre-built UI components for sign-in, sign-up, user profiles, organizations, and billing, plus SDKs, webhooks, JWT sessions, and a hosted backend that stores users. Features include social login, passkeys, MFA, SSO, B2B organizations, and a built-in billing layer for subscriptions and usage. The Hobby free tier covers up to 50,000 MRUs per app, and paid plans unlock MFA, custom branding, enterprise connections, and compliance add-ons.

overall90Clerk is the clearest default for React, Next.js, and Expo teams that need production auth in days rather than weeks. The pre-built components cover the long tail of flows teams routinely underinvest in, the Hobby tier includes 50,000 monthly retained users per app, and Clerk Billing makes the product closer to a user-management platform than a pure auth vendor. The rough edges are real: pricing can scale faster than expected once retained users or enterprise connections grow, Clerk Billing still has Stripe-related limitations, and the experience is weaker outside the React ecosystem. For most JavaScript teams, Clerk is a strong default worth comparing against WorkOS or Auth0 when enterprise requirements or cost dominate.
