Is there a go-to vendor/library that handles this (OIDC, SAML, SCIM) for SaaS services these days? Just like how everyone uses stripe for billing, everyone uses <vendor> for auth?
WorkOS does exactly this. It's "Stripe for enterprise features."
Our customers include OpenAI, Anthropic, xAI, Cursor, Perplexity, Vercel, Replit, Webflow, Clay, Hex, Carta, Plaid, Drata, Vanta, and many others. If you've used these products, you've used WorkOS!
WorkOS makes it easy to "cross the enterprise chasm." Here's a bit more of the backstory: https://x.com/grinich/status/1841569664465568248
