Compare Kubernetes ingress controller and gateway controller options by controller behavior, data plane, Gateway API or Ingress support, policy model, observability, and operational ownership.
Use this page as a decision guide, not a universal ranking. Validate any recommendation with a proof of concept that uses your own routes, policies, identity providers, logs, and deployment workflow.
Evaluation criteria
This page focuses on Kubernetes controllers that translate cluster resources into gateway or proxy data-plane configuration.
Separate the Kubernetes controller from the data plane it configures. The controller workflow and the gateway/proxy runtime are related but not identical.
Check whether the controller supports the Kubernetes resources your platform team wants to standardize on.
Compare how each controller attaches authentication, rate limiting, TLS, traffic splitting, observability, and custom gateway behavior.
Comparison matrix
Compare these options as Kubernetes controllers first, then evaluate their underlying gateway or proxy data plane separately.
| Criterion | Apache APISIX | Other ingress controller options |
|---|---|---|
| Controller role | Apache APISIX Ingress Controller watches Kubernetes resources and configures Apache APISIX as the data plane. | Kong Ingress Controller configures Kong Gateway; Traefik uses its Kubernetes providers; NGINX Ingress Controller configures NGINX or NGINX Plus; Envoy Gateway configures Envoy through Gateway API-oriented workflows. |
| Data plane | Apache APISIX is the data plane, so teams can use APISIX routing, upstreams, plugins, traffic control, observability, and security behavior. | Other controllers use their own data planes and policy systems. Evaluate the controller and data plane together, but do not collapse them into one generic API gateway comparison. |
| Ingress and Gateway API fit | Use Apache APISIX Ingress Controller when the team wants Kubernetes-native control for APISIX-backed ingress and gateway policy. | Use the same lens for each alternative: confirm Ingress, Gateway API, custom resources, annotations, and rollout workflow against your platform standard. |
| Policy attachment | Apache APISIX Ingress Controller lets teams connect Kubernetes routing resources with APISIX plugins for authentication, traffic control, security, and logs. | Kong Ingress Controller, Traefik, NGINX Ingress Controller, and Envoy Gateway use different combinations of plugins, middleware, filters, policies, annotations, and custom resources. |
| Comparison boundary | Compare Apache APISIX Ingress Controller with other ingress or gateway controllers. Compare Apache APISIX Gateway with gateway runtimes on separate pages. | For Kong, compare Kong Ingress Controller at the controller layer and Kong Gateway at the gateway runtime layer. The same separation applies to NGINX, Envoy, and Traefik. |
Alternative shortlist
Shortlist options by controller behavior, the data plane each controller configures, and how your team wants to attach gateway policy from Kubernetes.
Apache APISIX Ingress Controller is the Kubernetes controller path for using Apache APISIX as the data plane for ingress and gateway policy.
Kong Ingress Controller configures Kong Gateway from Kubernetes resources such as Ingress and HTTPRoute.
Traefik can act as a Kubernetes ingress controller through its Kubernetes Ingress provider and dynamic routing model.
NGINX Ingress Controller uses NGINX or NGINX Plus as the data plane for Kubernetes ingress traffic.
Envoy Gateway is a Kubernetes-native gateway project built around Gateway API and Envoy as the data plane.
Decision guide
Start with use case fit, then test the highest-risk policies and rollout path before committing to a production change.
You need an Apache 2.0 open-source API gateway with dynamic routing, a broad plugin hub, Apache APISIX Ingress Controller, and APISIX AI Gateway capabilities.
Another product may fit better when your main requirement is managed cloud convenience, a full API management suite, ingress-only routing, or service mesh data-plane control.
