GateForge

Product Features

What does GateForge solve?

Organizations running Red Hat 3scale API Management need a clear, automated path to Kubernetes-native API management via Red Hat Connectivity Link (Kuadrant). Manual migration is complex: mapping 3scale Products, Backends, Mapping Rules, Application Plans, and authentication configs to Gateway API HTTPRoutes, AuthPolicies, and RateLimitPolicies requires deep expertise in both ecosystems.

Compatibility Matrix

GateForge has been tested with the following Red Hat product versions:
