## Maven Central (Sonatype Central Portal) - post-2026 publishing limits

- `storage/maven-central-post-2026-publishing-limits` | fails-quota | 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://central.sonatype.org
- free tier: Maven Central introduced hard monthly publishing limits per organization in 2026. Three independent metrics: file count, release size, release count, evaluated as hard thresholds against the current calendar month, with a 30-day grace period on first breach (resets after 2 consecutive below-limit months). Thresholds are set near the top-10% of publishers; the published distribution table gives 90th percentile = 1,167 files / 78 MB release size / 7 releases per month, 99th = 17,724 / 1,808 MB / 50. Separately, from 2026-10-01, any artifact with a 'commercial nature' requires a paid Publisher Pro subscription regardless of volume. | unit: objects | metered on: unstated | read on: 2026-10-21 | source: [1]

- egress: Free and effectively unmetered for consumers - repo1.maven.org is a heavyweight CDN. Publishing is what is metered, not download. | metered: no
- identity: email
- interface: rest, rclone
- limits note: per-object-cap: none stated for a single artifact, but release size is the metered metric. request-rate: publishing limits are monthly per-org (file count / release size / release count). retention: indefinite for already-published artifacts - 'Public artifacts already published to Maven Central remain available for download.' Enforcement blocks new releases, not existing storage. Commercial-nature artifacts require Publisher Pro from 2026-10-01.
- interface detail: rest
- tooling: `mvn deploy` / central-publishing-maven-plugin, `gradle` publishing, `curl` to the Central Portal API, and plain HTTPS Maven-layout GETs from repo1.maven.org. No rclone backend.
- composes with: unlimited namespaces/group-ids x unlimited organizations x (monthly release-size threshold, ~78 MB at p90, ~1.8 GB at p99). Multiplying by many free organizations multiplies the account surface, not the rate, and every org has the same monthly reset.
- reliability: The 2026 change is the important signal for the whole niche: the largest free package registry concluded that '10% of namespaces accounted for more than 88% of all files published' and moved to hard monthly thresholds plus a commercial-use gate. Any plan that treats a public registry as a bulk blob store is now rate-limited at ~GB/month/org, not capped at a total. The exact thresholds table and the commercial-nature gate are new.
- notes: the same as the free tier
