Best For
Enterprise on-prem identity; legacy system integration; organizations standardized on Red Hat / Java stacks
API-first auth for AI startups; headless identity with flexible session management
Limitations
No agent SDK, no FGA, no human-in-the-loop; UI and developer experience are dated; heavy Java-based deployment
No FGA, no dedicated agent SDK, no human-in-the-loop; good primitives but requires more DIY for complex agent patterns
