Extensibility Nomenclature

A brief history of our terminology

Over the years, Adobe Creative Cloud applications have supported ExtendScript Scripts, Flash Panels, CEP Extensions, UXP Plugins (either regular or hybrid), and UXP Scripts. Uniquely, Adobe Express deals with add-ons, instead.

Most desktop applications have been supporting a different kind of compiled plugins, often spelled Plug-ins; for example, as Effects in Premiere or Filters in Photoshop.

While this continues to be the case, Premiere will use plugins1 as a catch-all term for panels, extensions, and, eventually, scripts as well. Primarily, this is to maintain consistency with the other Adobe Creative Cloud applications that have migrated—or are about to migrate—to the new UXP standard.





  1. More precisely, in the UXP ecosystem, a plugin is a container of either panel(s), command(s), or both. This mirrors—and extends—how the CEP ecosystem has been using extensions to contain panel(s).
