WorkOS
Enterprise SSO, SCIM directory sync and audit logs as an API.
NOT REALLY
why this verdict
Keep it — Anthropic has not replaced it
Anthropic's version overlaps, but does not finish the security job, so this one is still worth keeping open.
- A named launch, not a vibe named, unlinked
- AI startups reach enterprise deals faster and need SSO sooner. Anthropic, January 1, 2025 — no announcement link recorded yet.
- How much of the job it covers not the job editorial call
- Parts of it. The job still needs the tool to get finished.
- Is there a free way to do it? yes
- 2 of 2 listed replacements have a usable free tier: Clerk and Auth0.
- What the call is worth nothing to cancel
- No paid entry tier tracked, so there is no subscription to cancel.
Reason composed from the fields above missing: announcement linked recorded: free replacement listed recorded: two or more escape hatches

The backstory
WorkOS sells the checklist that blocks a startup's first big contract: SAML, SCIM, audit logs, domain verification. AI accelerated how quickly small teams get pulled into enterprise procurement, which made that checklist arrive earlier in more companies' lives.
