Probably the most extensibe and flexible API Gateway! If your gateway can't do it, try Membrane.
Membrane is an open source Java API Gateway that combines high performance with the flexibility of the Java ecosystem. It integrates with enterprise infrastructure and offers a rich feature set. Built on Spring Beans, Membrane is fully extensible and easy to adapt. No need to learn Lua or Go: use Java, JavaScript, or Groovy for customizations.
Thanks to Java’s legacy support, Membrane provides XML processing and Web Services integration (SOAP, WSDL) to modernize existing systems and bridge them with REST, OpenAPI, and JSON.
Membrane is cloud-native, container-ready, runs on Kubernetes and supports both YAML and XML configuration.
