Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Skopeo
- Single-purpose: it neither builds nor runs images, so it is one tool in a chain rather than a solution
- Command syntax with transport prefixes such as docker:// is unusual and trips people up initially
- Documentation is sparse compared with the rest of the container ecosystem
Yarn
- Yarn 2+ (Berry) has limited ESM support which can be a constraint for some projects
- Smaller ecosystem and community compared to npm, though still substantial

Answered from the vendors’ own pages
Skopeo: Is Skopeo free?
Yes, open source with no licence fee.
Yarn: What is Yarn's main advantage over npm?
Yarn downloads packages in parallel, significantly reducing installation time. It uses a yarn.lock file for deterministic installs, ensuring identical package versions across machines and preventing version conflicts common with npm.
SourceSkopeo: Why copy images without pulling them?
A registry-to-registry copy avoids downloading and re-uploading gigabytes, which is faster and much cheaper on bandwidth in CI.
Yarn: Can I use Yarn in offline environments?
Yes, Yarn supports secure offline environments. The yarn.lock file enables reproducible installs without requiring new downloads.
SourceSkopeo: Can Skopeo run containers?
No. It only inspects, copies, signs and deletes images. Running them is Podman’s or Docker’s job.
