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. “50k + 5 SSO”: SSO users: Amazon Cognito, Supabase Auth and Firebase Auth / Identity Platform bill SAML/OIDC per SSO user, not per connection (first 50 free, then $0.015 per SSO user a month). Their SSO results here assume 200 SSO users per connection (5 connections = 1,000 SSO users). See how 1,000 or 2,000 per connection changes the result or set your own. B2B: every SSO result assumes 1 customer organization per SSO connection (members = its SSO users, 200 by default). Published org caps and fees are applied, e.g. Clerk’s $100/mo B2B Authentication add-on above 20 members or 100 orgs, Auth0 Free’s 5-org cap, Descope $1/tenant over 35; plans over a cap are left out. All org terms · set your org count. * 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 SSOJet
Free $0 forever: unlimited users/MAUs/orgs, no enterprise SSO or SCIM. Business: monthly list $79/conn (2–4), $72 (5–9), $65 (10–24), $55 (25–49), $47 (50–99); annual ~25% less. SSO and SCIM each count as one connection on the same ladder.

Check before you switch
Unit (connection), SSO per-connection fees, and MFA availability change the ranking more than the headline price. Run your exact numbers in the calculator and read MAU vs MRU.
