WorkOS

WorkOS is a comprehensive platform designed to make your application enterprise-ready with minimal code. It offers a complete authentication and user management solution, including support for social authentication, magic links, multi-factor authentication, and single sign-on (SSO) via SAML or OIDC with directory sync. Users can be organized into multiple accounts, enhancing multi-tenant support. The AuthKit framework provides customizable UI components for all authentication types, and the platform supports invite-only signups.

The backend user management is free for up to 1 million users, and the platform includes SDKs for various programming languages and frameworks, ensuring seamless integration with both frontend and backend systems. However, the platform currently lacks support for passkeys or FIDO security keys, and its fine-grained authorization capabilities are still in private testing.

WorkOS also features an Admin Portal for self-serve onboarding, Directory Sync for user lifecycle management, and advanced event logging through Audit Logs. The platform is designed with developers in mind, offering modern RESTful APIs, real-time updates via webhooks, and support for multiple environments. It integrates with over 20 enterprise services, providing a unified and elegant interface for enterprise-level authentication and user management needs.
