WorkOS vs Auth0

Both authenticate your users, but they were built for different jobs. Picking by brand name instead of fit is the usual mistake.

The one-line difference

WorkOS is built for B2B SaaS that needs to sell to enterprises fast: enterprise SSO, SCIM, and admin portal as the core product. Auth0 (now part of Okta) is a broad, mature identity platform that covers consumer and B2B, with deep extensibility and a large feature surface.

Where WorkOS wins

• Enterprise readiness as the product: SSO and directory sync are the headline, not an upsell tier.
• Pricing model: historically priced around enterprise connections rather than punishing per-MAU growth on your whole base. Confirm current terms.
• Speed to first enterprise deal: the admin portal lets customers self-configure SSO.

Where Auth0 wins

• Breadth: consumer flows, B2B, extensive social connections, rules and actions for custom logic.
• Maturity and ecosystem: large docs, SDK, and integration footprint.
• One platform if you have both consumer and B2B identity needs.

The honest call

If you are B2B SaaS racing to close enterprise deals and want SSO and SCIM without a tier fight, WorkOS is the tighter fit. If you have mixed consumer and B2B needs, heavy customization, or already run on Auth0, the breadth justifies it. Watch Auth0’s MAU model and the SSO tier; see the pricing guide.
