## What it is
A self-hostable OCI container registry implemented as a Cloudflare Worker, storing image layers and manifests in Cloudflare R2 object storage. It supports full Docker push/pull workflows with username/password or JWT public-key authentication.

## Use cases
- self-host a docker container registry on cloudflare
- store container images in r2 object storage
- run a private docker registry without managing servers
- push and pull images with docker from a serverless registry
- authenticate registry pushes with jwt tokens
- replace harbor or docker hub with a cheap serverless registry

## When to choose
- you want a low-cost, serverless container registry on Cloudflare
- you already use Cloudflare Workers and R2 for infrastructure
- you need simple username/password or JWT-based registry auth
- you want full control over your image storage location

## When to avoid
- you need per-account or per-repository access scoping (not supported)
- you need a UI, vulnerability scanning, or image mirroring features
- you are not deploying on Cloudflare Workers
- you require fine-grained multi-tenant trust domains

## Facets
- artifact type: service
- maturity: active
- function: http-server, auth, object-storage, security
- domain: cloud-computing, self-hosted, infrastructure-as-code
- platform: serverless, self-hosted
