A tiny ConnectRPC gateway

Conny translates REST, gRPC, andgRPC-Web requests into the Connect, gRPC, or gRPC-Web protocols using a protobuf descriptor. One small binary in front of your backend — no config files, no sidecars, no control plane.

$ conny -d descriptor.pb http://localhost:8080

Descriptor-driven

No route config. Point conny at a buf build descriptor and REST paths, methods, and JSON mappings come from your protos.

One small binary

A single static Go binary — drop it in front of your backend, in a container, or in a Kubernetes pod.

Embeddable

Also a Go library: mount the gateway's http.Handler in your own server and middleware stack.
