I can vouch for this - I’ve just rolled out workos with three enterprise customers in the last 6 months. Super simple, great docs. Had been putting off SSO for years hoping something would come along and solve it for me.
E.g I know nothing about Azure AD but I just emailed the WorkOS setup link to our customer’s IT team, they followed the instructions and it just worked. No back and forth.
It’s an API for easily adding SAML, SCIM, and more. Currently being used in production by Vercel, Planetscale, Webflow, and +200 other apps.
