WorkOS

B2B auth with enterprise SSO

Free tier + paidAuth & user managementworkos.com

What it is

B2B identity platform. AuthKit gives you hosted sign-in, sessions and user management free up to one million monthly active users. The revenue model lives in enterprise add-ons instead: SAML single sign-on and SCIM directory sync, sold per connected customer organization.

Why it earns a slot

The free ceiling is absurd for a solo builder, and when your first enterprise buyer demands Okta SSO you switch it on per-connection rather than rebuilding your entire auth stack.

Know before you commit

The generous free MAU tier is a funnel into the real product: each SSO or SCIM connection costs $125/mo, so three enterprise customers means $750/mo. A custom domain is a further $99/mo.
