Why people look for Clerk alternatives
Clerk is used by React and Next.js teams that want production-ready sign-in, user profiles and organizations with prebuilt UI components. There is a free tier, and paid plans start at $25 a month, then grow with monthly retained users (MRU).
People look elsewhere because user data lives with a third party, per-user costs rise with scale, enhanced features such as SAML and advanced MFA cost extra, and there is less control than with self-hosted auth. When choosing a replacement, weigh where user records are stored, cost at your projected user count, enterprise SSO needs, and how hard migration out would be.
- User data lives with a third party
- Per-user (MRU) cost grows with scale
