## What it is
zot is a production-ready, vendor-neutral container image and artifact registry built purely on the OCI image format and OCI Distribution Specification. It is written in Go and designed for scale-out deployments, including Kubernetes environments.

## Use cases
- self-host a private docker container image registry
- store OCI artifacts and helm charts in a spec-compliant registry
- run a scale-out container registry for kubernetes clusters
- replace docker hub or harbor with a vendor-neutral OCI registry
- serve container images on-premises behind an air-gapped network
- distribute container images across multiple registry replicas

## When to choose
- you need strict OCI Distribution Spec conformance without vendor lock-in
- you want a lightweight, production-ready registry you can self-host or scale out
- you store non-image OCI artifacts like helm charts or signatures

## When to avoid
- you need docker-specific registry APIs beyond the OCI spec
- you want a registry with a rich built-in web UI and enterprise RBAC out of the box
- you primarily need a proxy cache for upstream registries with pull-through semantics
