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; Eclipse high memory consumption and CPU usage, especially with multiple plugins installed
  • They diverge on capability: containerd covers Full container lifecycle, Eclipse covers Java development environment.
  • Prices and features above were last checked on 30 August 2026.

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

Eclipse

  • High memory consumption and CPU usage, especially with multiple plugins installed
  • Slow startup times and performance degradation with large projects or many open editors
  • Requires configuration of eclipse.ini file to optimize heap sizes for adequate performance
  • User interface considered outdated compared to modern IDE alternatives
  • User base fell from 39% of Java developers in 2024 to 28% in 2025, indicating market decline

Questions people ask

Is containerd or Eclipse better?
Neither clearly leads. containerd starts at Free and Eclipse at Free, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
Which is cheaper, containerd or Eclipse?
containerd starts at Free and Eclipse at Free.
Does containerd or Eclipse run on more platforms?
containerd runs on Linux, Windows. Eclipse runs on Windows, macOS, 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 Eclipse is typically brought in for.

Answered from the vendors’ own pages

containerd: Is containerd free?

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

Eclipse: How much does Eclipse IDE cost?

Eclipse IDE is completely free and open-source, released under the Eclipse Public License 2.0.

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.

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.

containerd: Can containerd build images?

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