A system for visualizing a congruency of versions of an application across phases of a release pipeline includes a selecting engine to select a phase from a number of phases; a representing engine 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; a differentiating engine to differentiate a latest-deployed version of the application against a planned version of the application in a particular environment; and a comparing engine to compare, based on a selection, properties of the versions of the application.
