Cost Scale Analysis: When to choose Clerk over Supabase
Both Clerk and Supabase rely on identical hybrid flat-step pricing curves in this simulator. At equivalent workloads (free tier up to 10,000 MAUs, followed by a flat $25/mo up to 50,000 MAUs), their price trajectories align exactly, meaning the commercial decision pivots strictly on technical fit and compliance footprint.
Notably, Clerk supports a broader compliance footprint (SOC2, HIPAA, GDPR, SSO, SAML, 2FA) compared to Supabase (SOC2, ISO 27001, HIPAA), representing a critical differentiator for security audits.
