Cost Scale Analysis: When to choose Clerk over PlanetScale

PlanetScale is built on linear usage-based metrics, while Clerk 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, Clerk locks in a flat cost of $25/mo, whereas PlanetScale triggers automatic volume overages that drive monthly costs to $100+ at 20k MAUs.

Notably, Clerk supports a broader compliance footprint (SOC2, HIPAA, GDPR, SSO, SAML, 2FA) compared to PlanetScale (PCI DSS), representing a critical differentiator for security audits.
