Container Registry Comparison 2026: 12 Options Ranked
12 container registries compared: Docker Hub, ECR, GCR, ACR, Harbor, JFrog, GitHub, GitLab + 4 more. Pricing, self-hosting, open source, and scale.
Software developers have a wide range of container registry options today, whether they’re pushing containers into their own infrastructure or sharing artifacts with external customers.
Not every OCI registry exists for the same reason. Some are built for internal use, closing the loop between developers, CI/CD pipelines, and deployments inside a single organization. Others are designed for external distribution, helping software vendors get artifacts into customer environments, often across security boundaries or into air-gapped networks.
This post walks through the main registry options and looks at how each handles real-world software distribution.
First, some terminology.
Terminology
- Registry: A service that stores and distributes container artifacts. Examples include private Docker image registries, OCI registries, and the proprietary registries covered below.
- Artifact: Can mean a few things, but here it refers to an OCI-compliant image.
- Container Image: A specific type of artifact, made up of manifests and blobs.
- Digest: A unique identifier for a specific version of an artifact, typically a SHA256 hash. Immutable by design.
- Tag: A human-readable label for a specific version (
latest,v1.0, etc.) that points to a unique digest. Immutable tags in a registry mean the pointer cannot be repointed after the fact. - Manifest: Metadata describing how blobs combine to form a container image. Manifests can reference other manifests for multi-arch images.
- Blob: The actual data of an artifact, most commonly an archive of files.
- SBOM (Software Bill of Materials): A list of components and dependencies in a software build. Usually added directly as a layer on the OCI image.
- Image Signing: Cryptographic verification of image integrity and authenticity. The signature can be integrated directly into the OCI image.
- OCI Compliance: Adherence to Open Container Initiative standards so that OCI-compliant containers move cleanly across platforms.
What Is a Container Registry?
A container registry is the service software developers use to store, manage, and distribute container images and related OCI-compliant artifacts. It exposes APIs for pushing and pulling artifacts and is mostly consumed by CLI clients running in CI/CD pipelines or deployment targets. Mature registries add access control, analytics, and a UI on top.
For a deeper dive, including the difference between registries and repositories, see our complete container registry guide.
Understanding the OCI Format
OCI (Open Container Initiative) compliance ensures container images and artifacts behave consistently across platforms and tools. The OCI standardizes image formats, distribution methods, and runtime specifications. The result is portability and freedom from vendor lock-in.
Common tools like Helm, Docker, and ORAS all push and pull OCI-compliant artifacts. A growing pattern is using ORAS to package non-OCI-native formats (Kubeflow pipelines, configuration bundles, ML models) as OCI artifacts.
For example, a machine learning model can be pushed like this:
oras push registry.distr.sh/my-org/ml-model:0.0.1 ./model.pkl:application/vnd.myorg.modelFor a full explanation of OCI specifications, compliance requirements, and conformance testing, see our complete guide to OCI container registries.
Key Considerations When Choosing a Registry
When evaluating registries, focus on a handful of core criteria.
Internal vs. external use. Is this for your internal dev team’s workflow, or for distributing to customers? This is the most fundamental distinction and drives most of the other requirements.
OCI compliance level. How completely does the registry implement the OCI specification? This affects the artifact types you can store and distribute.
Security and access controls. For internal use, integration with your existing IAM is usually enough. For external distribution, you need granular controls over which artifacts are visible to which customers. Vulnerability scanning and image signing matter too. See our container registry security best practices for more.
Deployment flexibility. Can the registry be deployed where you need it? Cloud, on-premises, air-gapped environments? See our container registry use cases guide for more.
Support. Does the registry have a strong community behind it, or a commercial vendor standing behind it?
List of private (internal) container registries
Internal registries are built primarily for trusted, in-house use. They integrate tightly with cloud services, IAM, and CI/CD pipelines to support internal engineering teams.
They shine when development and deployment happen inside the same security boundary, with no external customer access required.
The trade-off is usually fewer knobs: limited UI, simpler access control, fewer analytics.
Azure Container Registry (ACR)
Azure Container Registry (ACR) lets users store artifacts in a default global namespace or organize them in more detail using the supported repository structure. Microsoft’s scale brings some compelling extras: global image replication, and built-in automation for building and patching images. Vulnerability scanning is there too, reportedly through an Aqua Security integration, though most of the documentation on that lives in Aqua’s docs rather than Microsoft’s.
Key features:
- OCI v1.1 compliant with strong Azure integration
- Supports specialized artifacts (WASM modules, Bicep files, ML models)
- Built-in Azure policy management and security
- Pricing transparency
- Automated container building and patching

Tight integration with the Docker CLI and a huge catalog of public images from official vendors and community publishers make it a convenient on-ramp for development. Rate limits and the security concerns that come with public registries often push teams to reserve it for base images or non-sensitive workloads.
Key features:
- Native integration with Docker CLI and Docker Desktop
- Public and private repositories
- Automated builds and webhooks for CI integration
- Official and Verified Publisher image libraries
- Rate-limited anonymous access (login recommended for better limits)
List of container registries that support external users
External registries face a different problem: distributing software to end customers, almost always outside your own organization. The priorities shift to access control, auditing, version visibility, and compliance. For more on the unique challenges of customer-facing container registries, see our guide to container registries for software distribution.
GitHub Container Registry and Docker Hub are excellent for open-source and low-security use cases, but they fall short for commercial software distribution because they lack:
- Granular access control. No way to give specific customers access to specific artifact versions.
- Air-gapped support. Limited options for distributing to high-security environments.
- Usage visibility. Missing audit logs and download tracking that commercial vendors need.
- License management. No built-in capability to manage software entitlements.
Purpose-built external registries like Distr exist to cover these gaps for vendor-to-customer distribution.
Distr
Distr ships with an OCI-compliant artifact registry built natively into the platform.
Distr itself is fully open source on GitHub and can be self-hosted. It provides a vendor portal where software and AI companies manage artifacts, invite end customers, and control licenses and access policies down to specific tags of an image or version of an application.
There’s also a customer portal where end customers see available artifacts and generate access tokens to pull from the registry.
Key features:
- Vendor and customer portals
- OCI-formatted and OCI-compliant artifact support (Helm, Docker, etc.)
- Built specifically for commercial self-managed deployment options for software and AI companies
- Advanced features: artifact tag restrictions, usage tracking, and granular access controls
- Available as a managed service (SaaS) via Get Started, or self-managed
- Open source and free to use
Who it’s for:
Independent Software Vendors (ISVs), B2B platforms, and enterprise software teams that distribute commercial software into customer environments, especially air-gapped, self-managed, or regulated deployments.

Which container registry fits your needs best?
- Enterprises using artifacts internally. JFrog Artifactory or Harbor for large organizations running complex internal workflows. Both offer robust access controls, multi-format support, and policy enforcement at scale.
- SaaS vendors hosted on a single cloud with no self-managed need. If your infrastructure sits inside one specific cloud, use that provider’s container registry.
- Non-commercial open source projects. GitHub Container Registry and Docker Hub for distributing public artifacts to a wide audience with minimal setup. Straightforward to adopt, compatible with standard tooling, widely known.
- Commercial open source and SaaS vendors that want to offer self-managed deployment options. Distr is built for software vendors distributing artifacts into external customer environments, including regulated, self-managed, and air-gapped deployments. Granular access controls, usage tracking, and flexible deployment models that internal or public registries don’t provide.
