Methods, systems, and computer-readable media for monitoring states of application packages deployed on a cloud-based application deployment platform. A notification service retrieves a copy of a deployed application package and metadata associated with the application package from the cloud-based deployment platform, and identifies libraries of the application package. The notification service can then determine which, if any, libraries are or will become out-of-date, and obtain license information about the libraries. The notification service can provide notifications of any outdated components and on license compatibilities or incompatibilities. The notification service can automatically restage the application package, or update the license, upon finding outdated components or license incompatibilities.
