Description
Clerk is an authentication and user management service founded in 2020 by brothers Colin and Braden Sidoti. Prebuilt components for sign-in, sign-up, and user profiles drop into React and Next.js applications, with the session handling, security hardening, and edge cases managed behind them. B2B SaaS teams adopt it for organizations, role management, and subscription billing in one SDK. Clerk Billing connects subscription plans to the same organization and user objects, which removes the glue code between authentication and payments.
