Cost Scale Analysis: When to choose Auth0 over Supabase
Auth0 is built on linear usage-based metrics, while Supabase operates on flat steps. Under 7.5k MAUs, both systems are highly efficient, scaling down to a clean $0/mo pricing footprint; however, between 10k and 50k MAUs, Supabase locks in a flat cost of $25/mo, whereas Auth0 triggers automatic volume overages that drive monthly costs to $100+ at 20k MAUs.
Notably, Supabase supports a broader compliance footprint (SOC2, ISO 27001, HIPAA) compared to Auth0 (HIPAA, PCI), representing a critical differentiator for security audits.
