Auth0 vs WorkOS
A comparison of Auth0 and WorkOS built from values read directly from each provider's own documentation, with the source recorded against every figure.
The short answer
- Pick Auth0 if
- Projects that fit inside the free 25,000 monthly active users, which includes an enterprise connection, self-service SSO and SCIM at no cost.
- Pick WorkOS if
- B2B products where the enterprise features are the product requirement — a million users cost nothing and you pay only for the connections your customers actually use.
3 sourced criteria separate them:
- Pricing model
- Auth0: Per monthly active user, chosen on a slider, with a discontinuity that is easy to miss: the free plan covers 25,000 MAU and includes an enterprise connection, SSO and SCIM, while the paid tiers start at 500 MAU and a footnote says keeping those three features requires upgrading to B2B.
- WorkOS: No monthly platform fee and no per-user charge below a million: WorkOS gives user management away and bills per enterprise connection instead — SSO and Directory Sync at $125 each per month, audit log streaming at $125 per SIEM connection, event retention at $99 per million events.
- Users included
- Auth0: 25,000 monthly active users on the free plan — the largest free allowance here apart from WorkOS. Essentials and Professional start at 500 and are priced upward from there.
- WorkOS: 1,000,000 active users free on AuthKit, then $2,500 per additional million. Two orders of magnitude above the other free allowances here.
- Audit logs
- Auth0: Audit log streaming to Datadog, Splunk, AWS and Azure, from the Essentials plan up. Auth0 publishes no retention window on the pricing page.
- WorkOS: Billed rather than bundled: $125 per month per SIEM connection for log streaming, plus $99 per month per million events stored.

Which should you choose?

B2B products where the enterprise features are the product requirement — a million users cost nothing and you pay only for the connections your customers actually use.

Consider something else if…
- Auth0: Leaving the free plan is a cliff rather than a step: paid tiers begin at 500 MAU, and a footnote says enterprise connections, SSO and SCIM need a B2B upgrade to keep.
- WorkOS: Those connections are the most expensive here at $125 a month each, so a long tail of small SSO customers costs more than it does at Clerk or Better Auth.
