Is containerd or Skopeo better?

Neither clearly leads. containerd starts at Free and Skopeo at Free, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.

Which is cheaper, containerd or Skopeo?

containerd starts at Free and Skopeo at Free.

Does containerd or Skopeo run on more platforms?

containerd runs on Linux, Windows. Skopeo runs on Linux, macOS.

Can I use containerd for free?

Both have a free tier, so you can try either at no cost before committing.

What is containerd best used for?

containerd is most often used for running the container runtime under a kubernetes cluster after the docker shim removal, building a platform or paas that needs to execute containers, reducing the moving parts on nodes that only ever run kubernetes workloads, embedding container execution inside another product. Of those, running the container runtime under a kubernetes cluster after the docker shim removal and building a platform or paas that needs to execute containers are not what Skopeo is typically brought in for.

What can containerd do that Skopeo cannot?

containerd covers Full container lifecycle, CRI support, OCI compliant, Snapshotter plugins. Skopeo covers Remote inspection, Registry-to-registry copy, Format conversion, Image signing.

The short version

Each has a real cost: containerd not a developer-facing tool: there is no build command and the CLI is deliberately minimal, so it needs companions like nerdctl or Buildah; Skopeo single-purpose: it neither builds nor runs images, so it is one tool in a chain rather than a solution
They diverge on capability: containerd covers Full container lifecycle, Skopeo covers Remote inspection.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

containerd

Not a developer-facing tool: there is no build command and the CLI is deliberately minimal, so it needs companions like nerdctl or Buildah
Debugging is lower-level than Docker, and error messages assume knowledge of the runtime internals
Documentation is aimed at platform engineers, so newcomers usually find Docker or Podman material more useful
No image building at all — that is out of scope by design

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

Answered from the vendors’ own pages

containerd: Is containerd free?

Yes. It is an open-source CNCF graduated project with no licence fee.

Skopeo: Is Skopeo free?

Yes, open source with no licence fee.

containerd: Do I need containerd if I use Docker?

You already have it. Docker uses containerd underneath to run containers; it is not an alternative you install separately.

Skopeo: 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.

containerd: Why did Kubernetes drop Docker for containerd?

Kubernetes talks to runtimes through the Container Runtime Interface. Docker did not speak CRI natively and needed a shim, so Kubernetes removed the shim and talks to containerd directly, which Docker was already using anyway.

Skopeo: Can Skopeo run containers?

No. It only inspects, copies, signs and deletes images. Running them is Podman’s or Docker’s job.

containerd: Can containerd build images?

No. Image building is deliberately out of scope. Tools such as Buildah, BuildKit or Docker handle that.
