Top Container Registries: Compare ECR, ACR, Docker Hub, GCR, and Harbor

Amazon Elastic Container Registry (ECR) is a fully managed container registry that lets you easily store, manage, share, and deploy container images and artifacts anywhere. ECR removes the need to operate your own repository or scale underlying infrastructure.

Azure Container Registry

Azure Container Registry allows you to generate, store, and manage container images and artifacts for all types of container deployments in a private registry. It handles private Docker images as well as related formats such as Helm charts, OCI artifacts, and images generated according to the OCI image format specification.

Docker Hub

Docker Hub is the world’s largest container image repository, hosting a wide range of content from community developers, open‑source projects, and independent software vendors. It is the simplest way to create, manage, and deliver container applications for teams.

Google Cloud Container Registry

The Container Registry provides a single location for your team to manage Docker images, perform vulnerability scanning, and control fine‑grained access to images. Integrated CI/CD pipelines enable fully automated Docker workflows for rapid feedback.

Harbor

Harbor is an open‑source registry that uses policy‑based and role‑based access control to protect artifacts. It ensures images are scanned, free of vulnerabilities, and signed as trusted images. Graduated from the Cloud Native Computing Foundation, Harbor offers compliance, performance, and interoperability across cloud‑native platforms such as Kubernetes and Docker.
