Adobe CEP (Common Extensibility Platform)

The Common Extensibility Platform (CEP) is Adobe's legacy framework for building integrated HTML5 panels across multiple Creative Cloud desktop applications. CEP panels use HTML5, CSS, and JavaScript for the UI layer and communicate with application DOMs through ExtendScript. The framework supports InDesign, Photoshop, Illustrator, Premiere Pro, Audition, After Effects, and other CC applications.
