Adobe UXP (Unified Extensibility Platform)

The Unified Extensibility Platform (UXP) is Adobe's modern cross-app plugin development framework replacing the legacy CEP platform. UXP uses a JavaScript engine with support for ES6+ and provides a common set of platform APIs for file system access, network I/O, and UI rendering using HTML, CSS, and curated Spectrum design components. Plugins built with UXP run natively within Creative Cloud desktop applications including Photoshop, InDesign, Illustrator, Premiere Pro, and XD.
