Monthly USD list prices, cheapest verified plan per vendor for each scenario, sorted by 50k-user cost. “—” = no fixed published price for that volume (custom / contact sales, or overage not printed). Billing units differ: Clerk counts retained users (MRU), most others MAU. * Logto Pro bills access tokens, not MAU (50k tokens included, then $0.08 per 100) — the figure is base fee only; token overage depends on your usage. How we calculate this.
Why teams leave Amazon Cognito
Essentials (default) free 10k MAU then $0.015/MAU (direct/social). Lite free 10k then $0.0055 / $0.0046 bands. Plus $0.020/MAU no free tier. Federated SAML/OIDC: 50 free then $0.015/MAU.
