Cost Scale Analysis: When to choose Auth0 over PlanetScale
Both Auth0 and PlanetScale rely on identical usage-based scaling curves in this simulator. At equivalent workloads (free tier up to 7,500 MAUs, followed by $23 base + $0.007 per additional active user), their price trajectories align exactly, meaning the commercial decision pivots strictly on technical fit and compliance footprint.
Notably, Auth0 supports a broader compliance footprint (HIPAA, PCI) compared to PlanetScale (PCI DSS), representing a critical differentiator for security audits.
