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.
