I'm the founder of WorkOS and we solve this problem for developers, primarily focusing on the challenges around enterprise SAML, SCIM, complex RBAC, fine-grained authorization, and more.

We build the Admin Portal for IdP configuration: https://workos.com/admin-portal

WorkOS actually launched on HN about 5 years ago[0] and today it's used by OpenAI, Cursor, Perplexity, and hundreds of other companies.

Feel free to email me if I can help: mg@workos.com
