Alibaba Cloud Container Registry vs Chainguard Registry

Alibaba Cloud Container Registry has no write-up on Specifiction yet; its figures are above.

Chainguard Registry provides Chainguard Containers: minimal container images rebuilt from source daily. Its directory lists 3,115 projects and 735,898 images. Chainguard says images are continuously built in SLSA L3 hardened infrastructure with CVE patching, and lists Sigstore-signed artifacts with build-time SBOMs and digital attestations. The free offer allows up to five images per organization; the FAQ describes a freely available set of about 50 images, limited to:latest tags and without a CVE remediation SLA. Catalog plans include upstream-supported major and minor tags, contractual remediation timelines of seven days for critical vulnerabilities and 14 days for other listed severity levels, and requests for new images. Catalog features also include automated Custom Assembly tooling, a private APK repository with more than 10,000 packages, and STIG-hardened and FIPS-validated images. Images can be pulled from Chainguard or mirrored to listed artifact managers. Chainguard lists compatibility with multiple scanners. Free Images costs nothing; Catalog is priced on request. The product runs on Linux, self-hosted, and web environments.
