ZITADEL review
A developer-focused IAM platform with strong core protocols and self-hosting options.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
ZITADEL is an open-source identity and access management platform for developers and organizations building customer-facing or business applications. It combines user authentication and authorization with centralized user management, single sign-on, multi-factor authentication, passkeys, audit trails, SCIM provisioning, and management, authentication, and session APIs. Multi-tenant organizations, delegated access management, and project grants make it relevant for applications serving multiple customer or business groups. Deployment options include managed cloud and self-hosted software across web, Linux, macOS, APIs, and private infrastructure.
Pricing is structured across four plans. The Free plan costs $0 per month and includes 100 daily active users, three external identity providers, unlimited users, and unlimited organizations. Pro costs $100 per month, includes 25,000 daily active users, three identity providers, a custom domain, and 500,000 management API requests. Enterprise Cloud and Enterprise Self-Hosted use custom pricing. Enterprise Cloud adds unlimited daily active users, a custom support SLA, and a Technical Account Manager; Enterprise Self-Hosted runs on the customer’s own infrastructure and includes a commercial license and custom support SLA. The Pro plan is usage-based and priced per month rather than per user.
ZITADEL’s ecosystem fit is centered on widely used identity standards: OpenID Connect, SAML, OAuth 2.0, and SCIM 2.0. Its feature set covers core authentication, federation, MFA methods including TOTP, SMS OTP, email OTP, U2F, and passkeys, plus lifecycle provisioning and event logging. That makes it a focused choice for teams that want open-source identity infrastructure, basic federation, and control over deployment. Organizations needing a broader verified integration catalog or more extensive access-policy coverage should compare alternatives before choosing it.
