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; Infisical free tier limited to 5 identities, suitable only for small teams or evaluation
  • They diverge on capability: containerd covers Full container lifecycle, Infisical covers Secrets management.
  • Prices and features above were last checked on 29 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

Infisical

  • Free tier limited to 5 identities, suitable only for small teams or evaluation
  • Pricing tiers are per-identity, which scales costs with team size
  • Certificate management requires Enterprise plan for advanced features like wildcards
  • Privileged access tier is separate billing from secrets management

Answered from the vendors’ own pages

containerd: Is containerd free?

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

Infisical: How is pricing calculated for Secrets Management?

Pricing is per-identity per month. Free tier includes 5 identities. Pro tier is $20/identity/month, Advanced is $40/identity/month. All pricing in USD.

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.

Infisical: Can I self-host Infisical?

Yes, Infisical's core is open-source under the MIT license and can be self-hosted. The managed cloud service is also available with additional features.

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.

Infisical: What is included in the Enterprise plan?

Enterprise plan includes SCIM, LDAP, approval workflows, external KMS/HSM support, and 99.99% SLA. Pricing is custom and determined by annual commitment.

Source
containerd: Can containerd build images?

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