The Adobe UXP Developer Tool (UDT) is a free, standalone application used to create, debug, and package plugins for Adobe Creative Cloud applications like Photoshop, InDesign, and Premiere Pro. It serves as the bridge for the Unified Extensibility Platform (UXP), Adobe’s modern standard for plugin development. Key Features of the Free UXP Developer Tool

- No background services (yet) – Plugins run only when their panel is open or a menu is invoked (persistent plugins are possible but limited).
