## What it is
Athens is an open-source, enterprise-ready implementation of the Go Module proxy server that caches and serves Go modules via the Go Modules download API. It stores modules in an immutable internal database with pluggable storage backends (disk, S3, GCS, MongoDB, CDN, in-memory) so teams can run their own public or private module mirror.

## Use cases
- run a private Go module proxy for my team
- cache Go dependencies behind a corporate firewall
- mirror Go modules for reproducible builds
- protect against force-pushed upstream Go modules
- serve private Go modules without exposing credentials to developers
- set GOPROXY to a self-hosted module datastore
- pre-fill a Go module cache for offline builds

## When to choose
- you need a self-hosted Go module proxy or mirror for compliance, privacy, or data continuity
- your team wants immutable, cached dependencies to guard against upstream tag rewrites
- you need to proxy private repositories with authentication
- you want pluggable storage backends and cloud deployment guides (Kubernetes, ECS, ACI, Cloud Run)

## When to avoid
- you only need a hosted solution and are happy with proxy.golang.org
- you need a proxy for languages other than Go
- you want a lightweight client-side caching tool rather than a server to operate
