WorkOS vs Auth0 for enterprise SSO

If your main need is enterprise SSO, the choice often comes down to:

• WorkOS: best if you want a B2B-focused, simpler, faster-to-ship enterprise auth layer
• Auth0: best if you want a broader, more mature identity platform with more features and flexibility

Quick take

Choose WorkOS if:

• You’re building a B2B SaaS
• You mainly need:
  • SAML / OIDC enterprise SSO
  • SCIM provisioning
  • Directory sync
  • Audit logs
  • Just enough auth infrastructure without a lot of complexity
• You want to get enterprise SSO working quickly with less implementation overhead

Choose Auth0 if:

• You need a more general-purpose auth platform for:
  • consumer auth
  • social login
  • passwordless
  • MFA
  • custom login flows
  • advanced policy/rules/hooks
• You need a platform with more mature enterprise identity features and a larger ecosystem
• You’re okay with more configuration and complexity

Main differences

Area	WorkOS	Auth0
Primary focus	B2B SaaS enterprise features	General identity platform
Enterprise SSO	Strong, streamlined	Strong, very flexible
SCIM / directory sync	Core feature, very polished	Available, but not the central focus
Implementation effort	Usually lower	Usually higher
Customization	More opinionated	Much more customizable
Consumer auth	Not the main focus	Excellent
Pricing model	Often attractive for B2B use cases, but enterprise pricing still applies	Can get expensive as usage grows
Developer experience	Simple and opinionated	Powerful but more complex

For enterprise SSO specifically

WorkOS strengths

• Easier to integrate for SaaS products selling to companies
• Built with enterprise onboarding in mind
• Good fit for “add SSO to your app” scenarios
• Usually less time spent dealing with identity edge cases

Auth0 strengths

• Better if SSO is only one piece of a larger auth strategy
• Strong support for many auth flows beyond enterprise SSO
• More control over login UX and authentication logic
• Good when you need a single platform for multiple identity use cases

A practical rule

• If you’re a B2B startup or SaaS and enterprise SSO is the main requirement, start with WorkOS
• If you need a full identity platform for multiple app types or complex auth behavior, go with Auth0

Things to check before deciding

1. Do you need SCIM and directory sync soon?
2. Is your product purely B2B, or also B2C/self-serve?
3. How much custom login and auth logic do you need?
4. Do you want the simplest possible enterprise SSO rollout?
5. What’s your expected scale and pricing sensitivity?

Bottom line

For enterprise SSO in a B2B SaaS, WorkOS is usually the better default.
For a broader identity platform with more features and flexibility, Auth0 is stronger.
