Best For
Rapid prototyping and Google-native stacks; low-friction auth for AI apps that don't need agent-specific authorization
Self-hosted identity infrastructure with Kubernetes-native deployment; strong FGA via Keto (SpiceDB-compatible)
Limitations
No token delegation, no FGA, no agent SDK; vendor lock-in to Google Cloud; limited authorization model
No dedicated agent SDK; requires significant ops expertise to run at scale; no human-in-the-loop out of the box
