The short version

  • Each has a real cost: Chainguard containers Catalog at 19,000 USD/year expensive for teams under 10 people; Docker shared kernel creates security vulnerabilities when containers share the same OS kernel that can bypass container isolation
  • They diverge on capability: Chainguard covers Hardened container images, Docker covers Container runtime.
  • 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.

Chainguard

  • Containers Catalog at 19,000 USD/year expensive for teams under 10 people
  • Per-image pricing for containers requires custom quotes with no transparency
  • Free tier limited to 5 container images for testing
  • Libraries pricing by ecosystem and developer count lacks transparent per-developer cost
  • VM image catalog pricing opacity makes cost estimation difficult

Docker

  • Shared kernel creates security vulnerabilities when containers share the same OS kernel that can bypass container isolation
  • Daemon socket exposure grants full root access to the host if compromised
  • Requires careful secrets management - credentials embedded in images or environment variables are easily harvested by attackers
  • Resource management complexity - misbehaving or compromised containers can consume all resources causing denial of service
  • Orchestration complexity - Docker Swarm is less capable than Kubernetes, requiring external tools for production deployments

Questions people ask

Is Chainguard or Docker better?
Neither clearly leads. Chainguard starts at Free and Docker at Free, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
Which is cheaper, Chainguard or Docker?
Chainguard starts at Free and Docker at Free.
Does Chainguard or Docker run on more platforms?
Chainguard runs on Cloud, Container, VM. Docker runs on Linux, macOS, Windows.
Can I use Chainguard for free?
Both have a free tier, so you can try either at no cost before committing.
What is Chainguard best used for?
Chainguard is most often used for deploying hardened container images with minimal attack surface, meeting supply chain security requirements for regulated industries, reducing cve exposure with contractual remediation guarantees, building secure language packages with automatic backports. Of those, deploying hardened container images with minimal attack surface and meeting supply chain security requirements for regulated industries are not what Docker is typically brought in for.
What can Chainguard do that Docker cannot?
Chainguard covers Hardened container images, CVE remediation SLA, SLSA L2/L3 builds, Sigstore signatures. Docker covers Container runtime, Docker Desktop, Docker Hub, Docker Compose.

Answered from the vendors’ own pages

Chainguard: How much is the Chainguard Containers Catalog?

The Containers Catalog is 19,000 USD per year for 10-person engineering teams, providing access to 2,000+ hardened container images.

Source
Docker: What is Docker pricing?

Docker offers a freemium model with Docker Personal free, Docker Pro at $11/user/month, Docker Team at $16/user/month, and Docker Business at $24/user/month. Each tier includes Docker Desktop, Docker Hub, and Docker Scout with different usage limits.

Source
Chainguard: What SLAs does Chainguard offer?

Chainguard provides contractual CVE remediation SLAs: 7 days for critical vulnerabilities, 14 days for high/medium/low severity, all with priority support.

Source
Docker: Can I use Docker in production?

Yes. Docker is used extensively in production environments. However, for container orchestration at scale, Kubernetes is typically paired with Docker to automate deployment, scaling, and management across clusters.

Source
Chainguard: Can I try Chainguard before purchasing?

Yes. The free tier includes five container images for testing and deployment, allowing hands-on evaluation.

Source
Docker: What are the main security concerns with Docker?

Key security risks include container breakout vulnerabilities through shared kernel exploits, daemon socket exposure that grants root access if compromised, weak isolation between containers, and credential leakage if secrets are embedded in images.

Source
Docker: Does Docker integrate with CI/CD systems?

Yes. Docker integrates with Jenkins, GitHub, and other CI/CD systems. The typical workflow involves GitHub repositories triggering automated builds in Jenkins, which prepare Dockerfiles and push images to Docker Hub for deployment.
