Agent Router (EAIG)

A Kubernetes-native AI gateway built on Envoy Proxy, extending the Gateway API with AI-specific routing, security, and observability.

✔High-performance Envoy data plane
✔Native Gateway API alignment
✔Extensible via enterprise plugins
Commercial API Gateway Extension

Kong AI Gateway

An extension of the Kong API Gateway adding AI-specific plugins for multi-LLM routing, semantic caching, and governance on top of Kong's existing gateway runtime.

✗AI capabilities are plugins layered on an existing gateway runtime, not a native AI gateway
✗Limited native Kubernetes Gateway API alignment
✗No native Envoy ecosystem or service mesh integration
✗Enterprise AI features tied to a separate commercial tier
