ZITADEL vs Logto
Both are alternatives to Okta. Here's how they stack up — verified facts, no spin.
Also searched as Logto vs ZITADEL — same comparison, one verdict.
ZITADEL
Multi-tenant identity built for products, not just employees.
ZITADEL is aimed at a different job: identity for your customers rather than your staff. It is multi-tenant by design, so a SaaS company can give each customer organisation its own users, branding and policies without running separate deployments. Event-sourced audit trail, passwordless and OIDC/SAML support, AGPL-3.0, around 15k stars, Swiss-based — which matters to buyers who care where the directory lives. If you are choosing an Auth0 replacement rather than an Okta replacement, this is the closest fit.
Logto
The fastest route from nothing to working sign-in.
Logto is the pragmatic middle: pre-built sign-in UI, SDKs for the common frameworks, social logins, MFA and multi-tenancy, deployable with Docker in well under an hour. It is aimed squarely at product teams who need authentication to work this week rather than an identity platform to administer for a decade. MPL-2.0 with a paid cloud tier. It is the smallest and youngest option here, which is the honest caveat, but for a startup replacing Auth0 it removes the most friction.
