Editorial take
Why it stands out
Pair with Auth0, Clerk, or Supabase Auth for baseline user accounts; compare Stytch or Descope when passwordless consumer onboarding is the headline feature.

Tool profile
Enterprise login building blocks: SSO, SCIM directory sync, and admin portals—meant to sit beside your app’s existing auth.
B2B products closing deals that demand SSO on the security questionnaire
WorkOS helps B2B SaaS teams ship SAML SSO, SCIM provisioning, and IT-admin experiences without becoming a full identity company overnight. It complements your own signup flows or a general-purpose auth provider by focusing on the enterprise checklist—domain verification, connection management, audit-friendly logs—while you keep product UX on your stack. It is the wrong first choice if you only need consumer Google sign-in and have no IT-driven requirements.
