Artifactory, a product by JFrog, is another tool that you can use for hosting your package feeds. Artifactory is originally an on-premises product, but it is now also available as a SaaS offering. Just like Azure Artifacts, it supports multiple protocols for interacting with package feeds. At the time of writing, Artifactory supports more repository protocols than Azure Artifacts. Examples of this include PHP Composer and Red Hat Package Manager (RPM).
JFrog has published an Azure Pipelines extension for downloading and uploading packages.
