Comparisons anchored on Zitadel, the AGPL-3.0 multi-tenant identity platform with OIDC, SAML and SCIM: against Ory's headless identity stack.
Which documented way to self-host Zitadel fits: the Linux binary, Docker Compose, or Kubernetes with the official Helm chart. Covers what each needs (a PostgreSQL instance in all cases), Zitadel's high availability recommendation, init and setup jobs, image tags, and what a stateless event-sourced server means for backups.
Zitadel Cloud against self-hosting Zitadel: published Free and Pro plan limits, the four cloud data regions, what Enterprise Cloud and Enterprise Self-Hosted contracts include, and why the commercial license matters for teams that cannot accept AGPL-3.0.
Two cloud-native identity platforms written in Go compared: Zitadel's built-in multi-tenancy, SAML and SCIM in the open source core versus Ory's headless components with those features in the Ory Enterprise License, plus licenses and databases.
Two B2B-oriented identity platforms with organizations: Zitadel (AGPL-3.0, event-sourced, Go) against Logto (MPL-2.0, Node.js), compared on tenant model, SAML and SCIM, self-hosting requirements, admin limits and cloud pricing published by each vendor.
Zitadel against Casdoor for multi-organization identity: instances and organizations versus Casdoor's shared organizations, protocol coverage (Casdoor adds CAS, LDAP and RADIUS serving), database support and licensing (AGPL-3.0 vs Apache-2.0).
Zitadel's multi-tenant CIAM against Kanidm's all-in-one identity server, which its own comparison page sets against Zitadel: SAML support, Unix and SSH integration, passkeys, database model and which suits customer identity versus workforce and Linux estates.
