Compare FusionAuth vs. ZITADEL

FusionAuth was built from the ground up to integrate with any app or language. Each feature (yes, every one) is exposed via an API which gives you total flexibility to handle any use cases. Every feature and acronym you need is included: registration & log-in, passwordless, MFA, SAML and OIDC. In seconds, you can comply with GDPR, HIPAA and COPPA requirements. FusionAuth can be installed on any platform, on any computer, and anywhere. FusionAuth Cloud, our fully managed SaaS hosting solution, allows you to host it yourself.

ZITADEL serves as an open-source platform for identity and access management, aiming to streamline the processes of authentication and authorization for various applications. It encompasses a robust array of features, including customizable login pages, compatibility with contemporary authentication techniques like Single Sign-On (SSO) and social logins, as well as the implementation of multifactor authentication to bolster security measures. Developers have the option to either integrate ZITADEL’s APIs into their applications for direct authentication or create specialized login interfaces tailored to their needs. Furthermore, the platform's role-based access control mechanism allows for meticulous permission management tailored to specific user roles, and its multi-tenant architecture makes it easy to extend applications to accommodate new organizations. ZITADEL's flexibility not only supports diverse workflows and user management processes but also adheres to brand guidelines, with features such as ZITADEL Actions enabling the execution of workflows triggered by specific events without necessitating further code deployments. As a result, ZITADEL is an adaptable solution for businesses looking to enhance their identity management strategies efficiently.
