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 Logto
Free: 50k MAU / 50k tokens. Pro from $24/mo: unlimited MAU, 50k tokens then $0.08 per 100 extra. Enterprise SSO add-on $48/connector. MFA add-on $48. Organizations add-on $48.
