Quick answer
What is Stytch?
Short answer
Stytch provides authentication infrastructure via a clean REST API, with SDKs for web and mobile platforms. Its core differentiation is passwordless-first authentication — magic links, email OTPs, SMS OTPs, passkeys, and biometrics are first-class features rather than add-ons. Stytch offers both a consumer (B2C) product and a B2B product (Stytch B2B) that includes organization management, enterprise SSO (SAML, OIDC), SCIM directory sync, and multi-tenant session management. It is headless by design — Stytch provides the backend; you build the UI. Verify current pricing and features at stytch.com.
- Best for
- Development teams that prefer full control over authentication UI, want passwordless authentication as a first-class experience, and are building consumer or B2B applications where authentication UX is a core product differentiator.
- When to choose
- Choose Stytch when your product vision prioritizes passwordless authentication, you prefer building your own auth UI (headless), and you need a clean API-first platform for either consumer or B2B applications.
- When not to choose
- Avoid Stytch if you want pre-built UI components (use Clerk), need self-hosted deployment, primarily need enterprise SSO without full auth (use WorkOS), or want a larger established ecosystem with broader SDK coverage.

Common use cases
- Passwordless consumer authentication via magic links, email/SMS OTPs, and passkeys
- B2B organization management with multi-tenant session handling and RBAC
- Enterprise SSO for B2B SaaS products via SAML and OIDC
- Biometric authentication for mobile and web applications

Strengths
- Passwordless authentication (magic links, OTPs, passkeys, biometrics) treated as first-class, not afterthought
- Clean, well-designed REST API with clear documentation
- Headless design gives maximum UI flexibility — no imposed component library
- Stytch B2B covers the full enterprise SaaS auth stack: SSO, SCIM, org management, RBAC
- Strong session management model designed for multi-tenant B2B scenarios
Limitations & considerations
- Headless-only — teams that want pre-built UI components should evaluate Clerk instead
- Smaller community and ecosystem than Auth0 or Clerk
- No self-hosted deployment option
- MAU-based pricing is separate for B2C and B2B products — model carefully for mixed use cases
- Less mature mobile native SDK compared to established platforms
Pricing model summary
Stytch uses MAU-based pricing with separate products for B2C and B2B use cases. Free tiers are available (verify current limits at stytch.com). Enterprise SSO and SCIM features may be in higher tiers. Verify current pricing with Stytch.
