Every developer pushes and pulls container images. But where you store those images matters — for build speed, security, CI/CD integration, and cost. Here are the best container registry and artifact management tools in 2026, from free options to enterprise platforms.
Docker Hub
Best for: Public open-source images and individual developers.
Docker Hub remains the default registry. It hosts millions of public images and integrates seamlessly with Docker CLI. Free tier: unlimited public repos, 1 private repo, 200 pulls/6 hours. Paid: $9/month for unlimited private repos and 5,000 pulls/day. Limitations: Rate limiting on free tier is aggressive (especially for CI/CD); image scanning requires Pro plan; no on-prem option.
docker pull nginx:latest # pulls from Docker Hub by default
docker tag myapp:latest myuser/myapp:v1
docker push myuser/myapp:v1GitHub Container Registry (GHCR)
Best for: Teams already on GitHub Actions and GitHub Packages.
GHCR is deeply integrated with GitHub: store container images alongside your code, manage access via GitHub teams, and pull images in GitHub Actions without authentication headaches. Free for public repos; private repos get 2GB free storage + data transfer within Actions. Standout features: Anonymous pulls for public images (no rate limits like Docker Hub), granular RBAC via teams, and built-in vulnerability scanning powered by GitHub's advisory database. Limitations: Less mature ecosystem than Docker Hub; no Helm chart support natively; storage costs add up for image-heavy projects beyond the free tier.
echo $CR_PAT | docker login ghcr.io -u USERNAME --password-stdin
docker tag myapp ghcr.io/myorg/myapp:v1
docker push ghcr.io/myorg/myapp:v1AWS Elastic Container Registry (ECR)
Best for: AWS-native deployments (ECS, EKS, Lambda containers).
ECR is the obvious choice if your infra lives in AWS. Image scanning is built-in (both basic and enhanced via Inspector), lifecycle policies auto-clean old images, and cross-region replication keeps images close to your compute. Cost: $0.10/GB/month storage, no pull pricing within AWS (data transfer out to internet applies). Standout: IAM-based auth (no static credentials), VPC endpoints keep traffic private, and pull-through cache repos can mirror Docker Hub to avoid rate limits. Limitations: AWS-only; the IAM auth model is powerful but complex for multi-cloud; no Helm repo support (use ECR Public or separate solutions).
Google Artifact Registry (GAR)
Best for: GCP workloads and multi-format artifact management.
GAR replaced Google Container Registry (GCR) and supports Docker, Maven, npm, Python, Apt, and Yum — all in one service. Regional repositories keep latency low. Cost: $0.10/GB/month storage, free within the same region. Standout: Vulnerability scanning (Artifact Analysis) is built-in; integrates natively with Cloud Run, GKE, and Cloud Build; supports immutable tags and customer-managed encryption keys. Limitations: GCP-centric; prices increase significantly with cross-region replication.
Harbor
Best for: Self-hosted enterprise environments with security compliance requirements.
Harbor is the leading open-source registry (CNCF graduated). It extends Docker Distribution with vulnerability scanning (Trivy/Clair), image signing (Notary/Cosign), RBAC, replication, and a clean web UI. Deploy anywhere — Kubernetes, vSphere, or bare metal. Cost: Free and open source. Standout: Full feature parity with commercial registries at zero license cost; OCI-compliant; supports Helm charts and CNAB; LDAP/OIDC integration; retention policies; and proxy cache to mirror remote registries. Limitations: You run it (operational overhead); scaling requires infrastructure expertise; upgrades need planning.
JFrog Artifactory
Best for: Large enterprises needing a universal artifact repository.
Artifactory supports 30+ package types (Docker, Maven, npm, PyPI, NuGet, Go, Conan, Helm, etc.) in one platform. It offers high availability, multi-site replication, and advanced metadata indexing for artifact traceability. Cost: Starts at $150/month for self-hosted Pro; cloud pricing varies. Standout: Universal — one tool for everything; rich metadata and AQL-based querying; deeply integrated with JFrog Xray for vulnerability and compliance scanning. Limitations: Expensive compared to alternatives; heavyweight to operate; overkill for small-to-medium teams.
Quick Comparison
| Registry | Best For | Free Tier | Self-Hosted | Multi-Format |
|---|---|---|---|---|
| Docker Hub | Public images, individuals | 1 private repo | No | No |
| GHCR | GitHub-native teams | Public repos free | No | No |
| AWS ECR | AWS deployments | 500MB/month | No | No |
| Google GAR | GCP + multi-format | 500MB/month | No | Maven, npm, PyPI, Apt |
| Harbor | Security/compliance | Free (OSS) | Yes | Helm, CNAB |
| JFrog Artifactory | Enterprise universal | None | Yes | 30+ formats |
Which One Should You Choose?
- Solo developer or small team on GitHub: GHCR — zero config, no rate limits on public pulls, tight GitHub integration.
- AWS shop: ECR — IAM auth, ECS/EKS integration, VPC endpoints.
- GCP shop or need multi-format support: Google Artifact Registry — regional, built-in scanning, supports Maven/npm/PyPI.
- Security-conscious enterprise or air-gapped environment: Harbor — open source, full control, CIS benchmarks.
- Large org with diverse artifact types: JFrog Artifactory — universal, but you'll pay for it.
- Just starting out: Docker Hub free tier + GHCR for private images. You can always migrate later.
Most teams end up using two registries: one cloud-native (ECR/GAR) for production and GHCR or Docker Hub for development and public images.
