Supabase Auth
Auth bundled with Supabase's hosted Postgres. 50k MAU free; Pro includes 100k MAU then $0.00325 per MAU.
Projects already using Supabase's hosted Postgres get auth on the same bill, and the per-MAU overage on Pro is among the lowest in this category. SAML SSO carries no connection fee, but SSO users are billed at $0.015/MAU after the first 50, as on Cognito and Firebase. Phone MFA is a separate add-on at $75/month for the first project. Free projects pause after a week of inactivity, EU regions are available on every plan, and the GoTrue auth server can be self-hosted.

Pro is $25/month per organisation (includes $10 of compute credits, which covers one small instance) with 100,000 MAU, then $0.00325 per MAU; third-party auth MAUs are priced the same. SAML SSO is available on Pro and Team with no per-connection fee, but SSO users are billed at $0.015/MAU after the first 50, which the calculator's per-connection SSO input cannot show. Advanced MFA (phone) is $75/month for the first project and $10/month per extra project. Team ($599/month) adds SOC 2, SSO for the dashboard and longer log retention at the same usage rates. Projects can be created in EU regions (Frankfurt, Ireland, London, Paris, Stockholm, Zurich) on every plan. The auth server (GoTrue) is open source and can be self-hosted. Supabase, Inc. is a US company.
