About ORAS

ORAS is a tool for working with OCI Artifacts. It treats media types as a critical piece of the puzzle and does not assume container images are the artifact in question. ORAS provides a CLI and client libraries to distribute artifacts across OCI-compliant registries. It can distribute artifacts across OCI-compliant registries or OCI Image Layout.

Used for

Attaching supply chain artifacts to container images.
Discovering and showing artifact reference relations.
Managing artifacts in OCI registries.
Migrating artifacts across registries.
Managing image manifest and layer in an OCI registry.

How to evaluate Artifact & Package Management

This is how the CIOPages Research Team evaluates this category. It is not an assessment of ORAS. It comes from our Container Registry & Artifact Management buyer guide.

25%

Supply-Chain Security & Provenance

Built-in vulnerability scanning (and whether it scans the binary or just the manifest), Cosign/Notation signing with content-trust enforcement, SBOM generation and storage (CycloneDX / SPDX), SLSA-style build provenance and attestation, and proactive quarantine of malicious or typosquatted dependencies before they enter

20%

Artifact & Format Breadth

Container/OCI plus the language ecosystems you actually use (npm, Maven/Gradle, PyPI, NuGet, RubyGems, Go, Helm, Debian/RPM); OCI-artifact support for non-image content; remote/proxy and virtual (aggregating) repositories; and whether one platform covers everything or you stitch several together

15%

Access Control, Multi-Tenancy & Governance

SSO/SAML/OIDC and SCIM, fine-grained and project-scoped RBAC, immutable tags and retention/cleanup policies, environment-promotion gates (dev→staging→prod), tamper-evident audit logging, and compliance posture (SOC 2 Type II, ISO 27001, FedRAMP where relevant)

15%

Distribution, Performance & Availability

Pull-through caching of upstream registries, geo-replication / edge distribution to your runtime regions, deduplication and storage efficiency, high availability and DR, and pull latency and throughput under CI burst and large-image load

15%

CI/CD & Platform Integration

Native hooks into your CI (GitHub Actions, GitLab, Jenkins, Argo), Kubernetes admission-control and OIDC-based keyless auth, webhooks/events, a complete REST API and Terraform provider for IaC, and cloud IAM integration if you live in one provider

10%

Operations & Cost Model

Self-managed vs. SaaS effort, upgrade and HA burden for self-hosted options, and how the meter works — per-user, storage, egress/data-transfer, or per-scan — because the unit of billing, not the headline rate, decides what you pay as pulls and image counts grow
