## What it is
Contour is a Kubernetes ingress controller that acts as the control plane for the Envoy proxy, deploying Envoy as a reverse proxy and load balancer. It supports the Ingress API, its own HTTPProxy CRD, and the Kubernetes Gateway API with dynamic configuration updates and multi-team ingress delegation.

## Use cases
- route external http traffic to kubernetes services
- manage ingress with gateway api
- delegate ingress configuration across teams
- terminate tls for kubernetes workloads
- rate limit and verify jwt at the edge
- deploy envoy as a kubernetes load balancer

## When to choose
- you need a high-performance L7 ingress controller for Kubernetes
- you want Gateway API or HTTPProxy features beyond basic Ingress
- you need multi-team ingress delegation and TLS certificate delegation
- you want dynamic Envoy reconfiguration without restarts

## When to avoid
- you are not running Kubernetes
- you need a simple single-binary proxy outside a cluster
- you prefer a different data plane than Envoy
