Cost Scale Analysis: When to choose Auth0 over Stytch
Auth0 is built on linear usage-based metrics, while Stytch 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, Stytch locks in a flat cost of $25/mo, whereas Auth0 triggers automatic volume overages that drive monthly costs to $100+ at 20k MAUs.
We recommend evaluating baseline limits like API throughput (Auth0: Dynamic vs Stytch: Dynamic) to avoid hitting overage throttles.
