Amazon ECR vs Quay.io

Pick ECR when you're already deploying on ECS, EKS, or Fargate — IAM-native auth means zero extra secrets to rotate, and same-region pulls to AWS compute are free, which Docker Hub and GHCR can't match once you factor egress meets developers should use quay. Here's our take.

Amazon ECR

Nice Pick

Pick ECR when you're already deploying on ECS, EKS, or Fargate — IAM-native auth means zero extra secrets to rotate, and same-region pulls to AWS compute are free, which Docker Hub and GHCR can't match once you factor egress

Pros

• Skip it for public open-source distribution: Docker Hub's discoverability and GHCR's free-for-public storage beat ECR's private-by-default, AWS-account-gated model for reaching outside contributors
• Related to: docker, kubernetes

Cons

• Specific tradeoffs depend on your use case

Quay.io

Developers should use Quay

Pros

• io when they need a robust, scalable container registry with advanced security features, such as vulnerability scanning and role-based access control, particularly in enterprise environments using Kubernetes or OpenShift
• Related to: docker, kubernetes

Cons

• Specific tradeoffs depend on your use case

The Verdict

Use Amazon ECR if: You want skip it for public open-source distribution: docker hub's discoverability and ghcr's free-for-public storage beat ecr's private-by-default, aws-account-gated model for reaching outside contributors and can live with specific tradeoffs depend on your use case.

Use Quay.io if: You prioritize io when they need a robust, scalable container registry with advanced security features, such as vulnerability scanning and role-based access control, particularly in enterprise environments using kubernetes or openshift over what Amazon ECR offers.

The Bottom Line

Amazon ECR wins

Pick ECR when you're already deploying on ECS, EKS, or Fargate — IAM-native auth means zero extra secrets to rotate, and same-region pulls to AWS compute are free, which Docker Hub and GHCR can't match once you factor egress
