Open Source Auth Alternatives to Okta
Identity and access management platform for enterprise.
Okta is a trademark of its respective owner.
Updated Sep 2026
What you gain
- ✓No per-user licensing that becomes the largest line item for large orgs
- ✓Full control over identity data and federation policies
- ✓No vendor dependency for employee and customer login
- ✓Self-hosted deployment for air-gapped or classified environments
What you give up
- △No Okta Integration Network with 7,500+ prebuilt SSO/SCIM connectors
- △No Okta Workflows for no-code identity automation
- △No FastPass for passwordless device-bound authentication
- △No managed Universal Directory for cross-app user sync
Switching Cost
Okta's lock-in is the integration network. Your user data exports as SCIM, but the 7,500+ app connectors with pre-configured SSO, SCIM provisioning, and lifecycle management don't transfer. Teams with 5-10 SSO integrations can rebuild in a week using SAML/OIDC standards. Enterprise orgs with hundreds of connected apps, Workflows automation, and governance policies should budget months. The hidden cost is the IT helpdesk load during transition: every employee's login flow changes, and every app needs reconfigured federation.

SSO (single sign-on), multi-factor auth, user directories, all in one place. The open source version is extremely capable.
keycloak

Keycloak is the default answer to "we need SSO but we're not paying Okta." It handles logins, SAML, OIDC, MFA, and user federation with LDAP and Active Directory for every app you own. Red Hat has backed it for over a decade, it's now a CNCF project, and every feature ships free under Apache 2.0.
Building Blocks
Okta is a platform. It bundles multiple capabilities into one subscription. These tools each cover one piece. Teams often assemble 2–3 of them instead of paying for the full suite.
