## What it is
A minimalist Go library implementing the GOPROXY protocol as an HTTP handler, letting developers build their own Go module proxy servers. It also ships a ready-to-use CLI binary and Docker image for running a proxy out of the box.

## Use cases
- self-host a Go module proxy server
- cache Go modules behind a private proxy
- mirror Go modules for an air-gapped or private network
- proxy the Go checksum database (sum.golang.org)
- build a custom Go module proxy with custom fetcher or cacher logic
- speed up Go module downloads for a team

## When to choose
- you want to embed a GOPROXY-protocol handler in your own Go server
- you need a simple, self-hosted Go module mirror or cache
- you need checksum database proxying or GOPRIVATE/GONOSUMDB support

## When to avoid
- you just need a public module mirror like proxy.golang.org or goproxy.cn
- you need a full-featured enterprise artifact manager (e.g., with auth, UI, multi-ecosystem support)
- you don't work with Go modules at all

## Facets
- artifact type: library
- maturity: active
- function: proxy, http-server, caching, package-manager, middleware
- domain: developer-tools, backend, programming-languages, self-hosted
- platform: go, cross-platform, cli, self-hosted
- tags: go-modules, goproxy-protocol, module-proxy, dependency-mirror, sumdb-proxying, docker
