Alternatives to Supabase Auth

step-up / DX-first

Clerk is the step-up when developer experience, pre-built auth UI components, and organization/team management features are worth the per-MAU cost. Clerk eliminates the setup work Supabase Auth requires for production-grade login UI, session management, and multi-tenant patterns.

Firebase Authentication
Decision brief →
Step-sideways / app-first auth

Firebase Authentication is the alternative for Google-ecosystem or mobile-first projects where Firebase's bundled backend services (real-time database, hosting, analytics) make an all-Google approach compelling. NoSQL data model vs Supabase's PostgreSQL is the core architectural tradeoff.

Step-up / CIAM platform

Auth0 handles enterprise CIAM requirements—SAML, advanced MFA policies, compliance certifications, RBAC—that Supabase Auth's lean auth layer doesn't cover. The right upgrade when enterprise customers start requiring SSO federation and audit logs.
