What's Good
Apache-2.0. containers/skopeo. `skopeo copy` / `inspect` / `delete` / `sync` across docker://, dir://, oci:, containers-storage:, and more — no container daemon required. Same containers org family as Podman/Buildah. Source github.com/containers/skopeo.
The Catch
Vs crane (go-containerregistry mutate/digest CLI) and Dive (layer UI): Skopeo is the *policy-friendly copy/inspect/sync* tool in the containers toolkit, not a layer explorer and not an image builder (that’s Buildah). Signing/policy config is powerful and easy to misconfigure once.
Verdict
Apache-2.0 daemonless image copy. Free forever; pair with Buildah/Podman, use crane when you live in go-containerregistry scripts.
