Best For
Multi-tenant SaaS, token delegation for agents, fine-grained authorization at scale
API-first auth for AI startups; headless identity with flexible session management
Limitations
Vendor lock-in on cloud plan; self-hosted (Private Cloud) is enterprise-tier only; dynamic client registration for MCP requires Enterprise plan to secure against abuse
No FGA, no dedicated agent SDK, no human-in-the-loop; good primitives but requires more DIY for complex agent patterns
