Our verdict on N42 Gateway
N42 Gateway is an open-source Kubernetes controller for teams that need to expose cluster applications through HAProxy. It supports both the Kubernetes Ingress API and Gateway API, dynamically applying configuration changes as cluster resources change. Deployment is self-hosted on Linux using container images and Helm, making it a fit for infrastructure teams that manage their own Kubernetes environments and want HAProxy-based request routing.
The feature set covers several operational concerns in one controller. N42 Gateway can issue and renew ACME certificates, route traffic through weighted blue-green deployments, and apply per-client connection and request-rate limits. It also supports external authentication with OAuth integration. For application-layer protection, the controller integrates with ModSecurity or Coraza for web application firewall functions. Its ecosystem connections include Kubernetes, HAProxy, Helm, ACME, ModSecurity, and Coraza, giving teams established components around the gateway rather than a separate proprietary stack.
The main trade-off is its focused deployment and configuration model. Teams need to operate the controller in a self-hosted Kubernetes environment, and organizations that do not use HAProxy may find the product less aligned with their existing gateway architecture. N42 Gateway suits teams seeking an open-source controller with both API models, TLS automation, progressive traffic routing, access controls, rate limiting, and WAF integration. Organizations looking for a managed-hosted ingress service or a gateway centered on a different proxy should consider another option.
