1. A system for visualizing a congruency of versions of an application across phases of a release pipeline, the system comprising: a selecting engine, comprising a processor, to select a phase from a number of phases; a representing engine, comprising a processor, to represent, via a user interface (UI), a congruency for a number of versions of an application compared against a target version of the application across the phases of a release pipeline, the congruency for the number of versions of the application represented with identifiers by: identifying the target version; determining if each of the number of versions of the application are rendered as a first identifier or a second identifier; and rendering the number of versions of the application in the UI as the first identifier or the second identifier; a differentiating engine, comprising a processor, to differentiate a latest-deployed version of the application against a planned version of the application in a particular environment by: exchanging, based on a selection of a user, the latest-deployed version of the application and the planned version of the application to a foreground or a background of the UI; overlapping coordinates associated with the latest-deployed version of the application and the planned version of the application in the UI; and rendering the latest-deployed version of the application as a third identifier in the UI; and a comparing engine, comprising a processor, to compare, based on a selection, properties of the versions of the application.
