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.
