Auth0 vs Descope

Auth0 is a developer-focused identity platform providing authentication, single sign-on, and authorization APIs/SDKs that applications integrate directly into their login flows. It offers a scalable and secure solution for managing user identities and access control, allowing developers to focus on building their applications without worrying about identity management.

Descope is a customer identity and access management (CIAM) platform that handles authentication and authorization for consumers, business customers, partners, and increasingly AI agents and MCP servers. It provides a no-code, drag-and-drop workflow builder for creating signup, login, MFA, and SSO flows without hand-rolling authentication logic. The platform supports a wide range of authentication methods including magic links, passkeys, social login, one-time passwords, SAML/OIDC SSO, and FIDO2, plus fine-grained authorization models like RBAC, ReBAC, and ABAC. Descope ships SDKs for major frontend and backend frameworks and offers identity orchestration that syncs with more than 50 third-party tools.
