The Top 8 WorkOS Alternatives for B2B Auth & SSO

WorkOS is a widely used tool for developers aiming to integrate enterprise-grade features such as SSO and SCIM provisioning into their applications, but it often leads to increased engineering responsibilities as products mature. Developers frequently seek alternatives due to WorkOS's limited flexibility, high costs, narrow feature scope, and lack of built-in orchestration and multi-tenancy support. Alternatives such as Descope, Auth0, Amazon Cognito, Firebase Authentication, Supabase, Keycloak, Ory Kratos, and FusionAuth offer varying degrees of customization, integration, and scalability to address these gaps. Each alternative is tailored to different technical requirements and growth stages, with Descope noted for its comprehensive identity platform and orchestration capabilities, while others like Auth0 and Keycloak are valued for their enterprise readiness and open-source control, respectively. As identity needs evolve, choosing an alternative depends on the desired balance of flexibility, enterprise features, and orchestration capabilities.
