regclient is a Go client library and set of CLI tools (regctl, regsync, regbot) for interacting with Docker and OCI conformant container registries. It supports inspecting, copying, retagging, mutating, and deleting images and OCI artifacts without requiring a container runtime or privileged access.

Use cases

• copy container images between registries
• list tags in a docker registry
• inspect image manifests without docker
• sync images to a private registry
• delete tags from an OCI registry
• query docker hub rate limits
• mutate image labels and annotations
• work with OCI image layouts locally

When to choose

• you need to script registry operations without installing Docker or a container runtime
• you want efficient image copying that preserves digests and only pulls required layers
• you need to manage multi-platform images, OCI artifacts, or referrers
• you want to automate registry mirroring or retention policies

When to avoid

• you need a full container build system like Docker or BuildKit
• you only run containers and never manage registry content directly
• you need a GUI for managing images
