Each URL serves packages that Chainguard builds from source. If your organization turned on <a href="https://www.chainguard.dev/docs/chainguard/libraries/introduction#upstream-fallback-and-controls">upstream fallback</a>, it also serves packages from the public registry, such as the npm Registry, that Chainguard hasn&rsquo;t built.</p>
