  "what": "Hosted authentication with prebuilt React and Next.js components — sign-in, user profile and organization UI you drop in as JSX. Handles sessions, MFA, passkeys, social login and B2B organizations. Billing is measured in monthly retained users rather than raw signups, so users who never return are never charged.",
  "why": "Fastest zero-to-login path in the React world: drop in the <code>SignIn</code> component and you have a styled production auth page in minutes. The Feb 2026 jump to 50k free users made it viable far longer than before.",
  "warn": "The free tier jumped to 50k MRU in February 2026, but enterprise SSO, user impersonation and enhanced B2B org features sit behind $100/mo add-ons that stack on top of Pro. Clerk-hosted components mean your login UI lives in their iframe-free but proprietary React layer.",
