Zitadel

Swiss open-source identity platform with multi-tenancy built in. The cloud Pro plan bills per daily-active-user day.

Swiss jurisdiction and a choice of EU, US, Swiss or Australian data residency on all plans suit teams that prefer a non-US vendor. Pro costs $100/month and bills per daily-active-user day, so cost depends on login frequency: at weekly logins the included 25,000 DAU covers about 6,250 MAU, while daily users cost 7.5 times as much. External identity providers, including social and enterprise SAML/OIDC, share 3 included slots, then $100 per block of 5. The AGPL-3.0 edition can be self-hosted free.

Daily users cost 7.5 times as much, monthly users a quarter as much. The calculator flags estimates above $3,000/month for a sales conversation.
