A Technical Deep Dive in WebAssembly for Kong Gateway

WasmX is an nginx module embedding a Wasm VM into Kong Gateway, implementing the Proxy-Wasm interface and supporting multiple Wasm runtimes. The demo compiles a Rust filter, drops it into Kong, enables it on a route and visibly returns 429 rate limit responses, proving the filter runs in-process and enforces limits. Integration with the existing Lua VM and the declarative Kong config is shown, performance and inclusion in the next Kong release are claimed.
