- `storage/quay-io-public-repositories` | qualifies | evidence reported | binding none | category registry
- identity a placeholder: card and phone unknown | verified 2026-10-21 (inherited) | stale on 2026-11-05
- url https://quay.io
- free tier: "We offer unlimited storage and serving of public repositories" — Red Hat's own support article. Every paid plan is priced only by private-repo count and lists 'Unlimited public repos'; a free account gets unlimited public repos, private repos require a 30-day trial then a paid plan. | unit: unlimited | metered on: stored-bytes | read on: 2026-10-21 | source: [1]
- per-object cap: not stated | source: [1] | note: not stated
- retention: Every paid plan is priced only by private-repo count and lists 'Unlimited public repos'; a free account gets unlimited public repos, private repos require a 30-day trial then a paid plan | days: 30 | source: [1] | note: not stated
- egress: Included in 'unlimited storage and serving of public repositories' — no per-GB line item exists for public repos on any plan. Served over quay.io's own CDN edge. | metered: no
- identity: anonymous
- interface: oci
- limits note: Requires a Red Hat SSO account to push (anonymous pull only). Quay is a shared hosted registry: pull QPS and total storage are subject to undisclosed fair use; the paid tiers exist purely to buy private repos, which signals public storage is deliberately not metered.
- interface detail: oci
- tooling: oras push / docker push / skopeo; Cosign/notation signing supported natively.
- composes with: N public repos x N free Red Hat accounts. Repos are namespaced per user/org, so one account already gives effectively unbounded blob count; orgs are free to create.
- reliability: Hosted multitenancy means a noisy-neighbour throttle is possible but not documented; no data-expiry policy on public repos, so blobs persist indefinitely.
- notes: the same as the free tier
