Alternatives to Clerk

Step-up / CIAM platform

Auth0 is the step-up for teams that need enterprise CIAM features—custom domains on all tiers, advanced MFA policies, fine-grained RBAC, and compliance certifications (SOC 2, HIPAA)—that Clerk's developer-first model doesn't include at comparable price points.

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

Firebase Authentication is the alternative for Google-ecosystem projects and mobile-first apps where Firebase's real-time database, hosting, and analytics make a fully integrated backend attractive. Lower component-level polish than Clerk but no separate auth service required.

Supabase Auth
Decision brief →
Step-sideways / dev platform auth

Supabase Auth is the natural alternative when the team is already using Supabase for its PostgreSQL database—auth is bundled in the same project at no extra cost. Best for open-source-friendly teams that want to self-host rather than pay per-MAU.

AWS Cognito
Decision brief →
Step-sideways / cloud-native

AWS Cognito is the step-up for AWS-native applications that need enterprise-grade scalability, compliance certifications, and deep IAM integration. More complex to configure than Clerk but zero additional vendor dependency for teams already running on AWS.
