 - A fully featured [reference implementation](https://github.com/envoyproxy/envoy/tree/main/source/extensions/filters/http/ext_proc) (C++) can be found in the Envoy GitHub repository.
 - A second implementation (Rust, non-Envoy) is available in [Agent Gateway](https://github.com/agentgateway/agentgateway/blob/v0.5.2/crates/proxy/src/ext_proc.rs).
