See an overview of how project subscriptions are allocated within different JFrog Subscription plans:
Projects Support in the JFrog Platform: From Artifactory 7.31.10, the JFrog Projects feature is now supported on all JFrog Subscriptions, but varies in the number of projects, according to the following subscription types:
Pro/X subscription: Up to 3 projects (No option to extend this subscription).
Enterprise subscription: Up to 30 projects.
Enterprise+ subscription: Up to a total of 300 unique projects for each subscription, with the option to increase the number of projects by purchasing an additional License Bucket. Each bucket supports an additional 100 projects.
Project support for Enterprise+ Subscriptions: Mission Control manages the number of projects for Enterprise+ subscriptions at the subscription level rather than per JPD instance. The total project count applies to your entire deployment across all JPD instances, independent of server count.
Projects are not currently supported on Artifactory Edge devices. For more information, see Installing Artifactory Edge.
