Adobe UXP

Adobe UXP (Unified Extensibility Platform) is the modern plugin and scripting platform used across Adobe creative applications including Photoshop, InDesign, Illustrator, and XD. It provides a JavaScript-based runtime with access to application APIs, a React-compatible UI framework, and a unified plugin distribution system via the Creative Cloud marketplace. UXP replaces the older CEP (Common Extensibility Platform) and ExtendScript plugin architectures.
