Verdict in one paragraph

B2B-focused vs general-enterprise. WorkOS is purpose-built for B2B — SSO, SAML, SCIM, directory sync. Auth0 is general-purpose enterprise auth. For B2B SaaS where every customer is an organisation, WorkOS's pricing model and feature set are meaningfully better. For products with mixed B2C and B2B, Auth0 covers both.

Decision criteria

  • Which is the right pick for B2B-only SaaS?

    WorkOS

    WorkOS targets exactly this. Pricing tier, SSO/SAML focus, directory sync.

    Auth0

    Auth0 covers B2C natively. WorkOS does not target individual users.

  • Which has the better SSO/SAML implementation?

    WorkOS

    WorkOS's SSO/SAML is best-in-class. Auth0's is fine but more general-purpose.

  • Which is cheaper for B2B SaaS at scale?

    WorkOS

    WorkOS's AuthKit free up to 1M MAUs makes a huge difference at growing-startup scale.

    Auth0

    Auth0 / Okta is more often pre-approved at large enterprises.

  • Which has the broader feature surface?

    Auth0

    Auth0's product surface is wider — Rules, Hooks, customisation depth WorkOS does not match.
