Apache APISIX is an open-source, high-performance, cloud-native gateway that addresses the limitations of legacy Nginx-based solutions. Built on Nginx and LuaJIT via OpenResty, it uses etcd for configuration storage to eliminate reload-induced latency, making it well-suited for dynamic microservices and serverless architectures. Its primary strength is its fully dynamic, pluggable architecture, which allows teams to customize traffic management, security and observability through APIs and a multi-language plugin ecosystem, including WASM. By supporting the Kubernetes Gateway API, Apache APISIX can be used as a Kubernetes gateway and is a strong candidate for replacing legacy Nginx ingress controllers. Some of our teams are adopting Apache APISIX and find its performance and feature set compelling.
