Okta vs Keycloak -- Identity & Access Management Compared

Okta vs Keycloak

Keycloak is the leading open-source alternative to Okta, providing SSO, MFA, and identity brokering with zero licensing costs. The trade-off is clear: Keycloak gives you complete control, customization, and data sovereignty, but demands significant engineering investment to deploy, operate, and maintain. Okta removes that operational burden with a managed cloud platform and the broadest integration ecosystem, but at a substantial per-user cost.

The Verdict

Choose Keycloak if you have the engineering talent to operate identity infrastructure and want to eliminate licensing costs while gaining full customization and data sovereignty. Choose Okta if you need a managed identity platform that provides the broadest integration network, enterprise support, and governance features without the operational burden of self-hosted infrastructure.
