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; Linear no task-level Gantt chart; Timeline view is available for projects only, not individual issues
  • They diverge on capability: containerd covers Full container lifecycle, Linear covers Fast, real-time sync.

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

Linear

  • No task-level Gantt chart; Timeline view is available for projects only, not individual issues
  • No native time-tracking or hour-logging feature
  • No native Linux desktop app; official FAQ states it 'may come in the future but it's not on the roadmap for now'
  • Free tier capped at 250 issues and 2 teams

Answered from the vendors’ own pages

containerd: Is containerd free?

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

Linear: How much does Linear cost?

Linear has a free tier supporting 2 teams and 250 issues. Paid plans start at $10 per user per month for Basic and $16 per user per month for Business. Annual billing is required for paid tiers.

Source
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.

Linear: What are the file upload limits on Linear?

The free tier is restricted to 10MB file uploads per team. Paid plans offer unlimited file uploads.

Source
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.

Linear: Does Linear offer an Enterprise plan?

Yes, Linear offers an Enterprise tier with custom pricing, annual billing required, SAML and SCIM support, granular admin controls, and priority support.

Source
containerd: Can containerd build images?

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