# Gateway API routing visibility in Kubernetes

> Visualize Gateway API in Radar: the full network path from GatewayClass through Gateway and HTTPRoute to Service and Pod, with typed route detail views.

[Gateway API](https://gateway-api.sigs.k8s.io/) is the next-generation Kubernetes networking API, replacing Ingress with more expressive routing, traffic splitting, and multi-tenant support.

### What Radar Shows

**Topology:** Full network path  -  GatewayClass → Gateway → HTTPRoute/GRPCRoute/TCPRoute/TLSRoute → Service → Pod. Visualize how traffic flows from the gateway controller through routes to your backend services.

**Gateway Detail View:** Listeners, addresses, attached routes, and status conditions.

**GatewayClass Detail View:** Controller name, description, parameters reference, and status conditions.

**HTTPRoute Detail View:** Rules with path/header matching, backend references, filters, and weights.

**GRPCRoute Detail View:** Service/method matching, backend references, and filters.
