Is containerd or Linkerd better?

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

Which is cheaper, containerd or Linkerd?

containerd starts at Free and Linkerd at Free.

Does containerd or Linkerd run on more platforms?

containerd runs on Linux, Windows. Linkerd runs on Kubernetes, Linux.

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 Linkerd is typically brought in for.

What can containerd do that Linkerd cannot?

containerd covers Full container lifecycle, CRI support, OCI compliant, Snapshotter plugins. Linkerd covers Automatic mutual TLS, Golden metrics, Rust micro-proxy, Traffic policy.

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; Linkerd deliberately fewer features than Istio, so complex routing and multi-cluster policy can hit its limits
They diverge on capability: containerd covers Full container lifecycle, Linkerd covers Automatic mutual TLS.

Where they differ

Only the attributes on which containerd and Linkerd actually diverge.

Attributes where containerd and Linkerd differ
Attribute	containerd	Linkerd
Platforms	Linux, Windows	Kubernetes, Linux

Identical on both: starting price (Free), pricing model (Open source, no licence fee), free tier (Yes), user rating (Not yet rated), category (Cloud).

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

Linkerd

Deliberately fewer features than Istio, so complex routing and multi-cluster policy can hit its limits
Kubernetes only, with no story for workloads outside a cluster
A sidecar per pod is still real memory and latency overhead, however small, and a mesh is another layer to debug during incidents

Answered from the vendors’ own pages

containerd: Is containerd free?

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

Linkerd: Is Linkerd free?

The open-source project is free. Buoyant, its maintainer, sells enterprise distributions and support separately.

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.

Linkerd: Linkerd or Istio?

Linkerd trades features for simplicity, with a smaller proxy and far less configuration. Istio is more capable and correspondingly more work to run.

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.

Linkerd: Do I need a service mesh at all?

Only if you need mutual TLS, uniform retries or per-service traffic metrics across many services. For a handful of services it is usually more machinery than the problem justifies.

containerd: Can containerd build images?

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