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 WorkOS
AuthKit free to 1M MAU then $2,500/mo per additional 1M. SSO and Directory Sync each: $125 (1–15), $100 (16–30), $80 (31–50), $65 (51–100).
