HAProxy Ingress vs Traefik Proxy

HAProxy Ingress is a free, self-hosted controller that configures HAProxy to route external requests to applications in a Kubernetes cluster. It applies changes made in the cluster to HAProxy without requiring a separate update process. The project supports Ingress and Gateway API resources and describes more than 200 configuration options. Gateway API support is partial: the documented implementation covers GatewayClass, Gateway, TCPRoute, and HTTPRoute, but not HTTPRoute filters or resource status updates. Installation uses a Helm chart and requires Helm 3, a running Kubernetes cluster, and administrative privileges in that cluster. Version 0.16 requires Kubernetes 1.21 or newer. Local cluster options named by the project include minikube, kind, k3s, k3d, and colima. It associates requests with ingress hosts using TLS SNI and the Host header. Metrics can be collected with Prometheus and Grafana using Prometheus Operator. The project uses the Apache-2.0 license and lists community channels including Slack, a users mailing list, and Stack Overflow.

Traefik Proxy is a free, open-source reverse proxy and ingress controller for deploying services and APIs. It discovers services and adjusts routing dynamically, supporting HTTP, HTTP/2, HTTP/3, TCP, UDP, WebSockets, and gRPC.

Security options include automatic HTTPS, Let’s Encrypt, custom certificates, authentication, and Web Application Firewall support. Integrations span Kubernetes, Docker, Docker Swarm, Red Hat OpenShift, Rancher, Amazon ECS, Consul, and key-value stores. It supports deployment on environments including Kubernetes distributions, virtual machines, bare metal, Docker Swarm, and HashiCorp Nomad. Observability includes OpenTelemetry, a built-in dashboard, distributed tracing, and metrics integrations. WebAssembly plugins and a public plugin catalog provide extension options.
