The Top 6 Frontegg Alternatives for B2B Auth and SSO

Frontegg is a customer identity platform catering to both B2B and B2C applications by providing authentication, user management, and embedded admin portals with enterprise-grade features such as single sign-on (SSO) and role-based access controls. While it serves as a strong foundation for implementing identity solutions, it often falls short as applications grow due to its limitations in flexibility, customization, and scalability, leading developers to explore alternatives. These alternatives include Descope, Auth0, FusionAuth, Amazon Cognito, Keycloak, and Ory, each offering distinct advantages. Descope, for instance, provides a workflow-driven platform with customizable identity flows, while Auth0 offers extensive identity coverage and flexibility. FusionAuth is favored for its predictable pricing and infrastructure control, Amazon Cognito integrates deeply with AWS services, Keycloak provides open-source flexibility, and Ory offers a modular, API-first architecture. These platforms address the need for adaptable authentication journeys, seamless onboarding, and integration capabilities, which are essential as identity requirements become more complex and demanding.
