Platform Overviews
Stytch
Stytch is a developer-focused authentication API specializing in passwordless methods — magic links, passkeys, and one-time passcodes — aimed at teams that want modern auth UX without building it themselves, and often chosen over Auth0 for its API-first (rather than pre-built-UI-first) approach. Our engine detects Stytch through 2 script patterns and 1 HTML pattern tied to its client SDK and embedded authentication flows. As a hosted API platform, detection indicates a live backend integration rather than a self-built auth system. Documented at stytch.com.
Auth0
Auth0 (now part of Okta) is an enterprise-grade authentication and identity platform offering login, SSO, and user-management APIs that developers embed rather than build in-house — common on B2B SaaS products and larger applications with complex identity requirements (social login, MFA, enterprise SSO). Our engine detects Auth0 through 3 script patterns tied to its client-side SDK (Auth0.js / Lock), 2 HTML patterns matching its hosted login-widget markup, and 1 CDN domain serving its assets. As a hosted identity platform, a detection confirms live integration with Auth0's managed service rather than a self-hosted auth system. Documented at auth0.com.
