The is a standalone app (Windows/Mac) that bridges your code editor to the Creative Cloud app. It’s not just a logger—it’s a live reload, inspect, and test harness.
If an event listener fails or an API call returns an unexpected payload, click in UDT. The Chrome DevTools window appears. You can jump to the Console tab, inspect the specific error stack trace, insert a debugger; statement in your code, and trace execution line by line. Pro-Tips for Optimizing Your UDT Experience
If UXP is the engine, the is the steering wheel. UDT is a desktop application that simplifies the process of creating, loading, managing, debugging, and packaging plugins for Adobe's UXP-powered applications. adobe uxp developer tool hot
Adobe’s Unified Extensibility Platform (UXP) has fundamentally changed how developers build plugins for Creative Cloud applications like Photoshop and Illustrator. Moving away from the older Common Extensibility Platform (CEP), UXP delivers native-performance user interfaces by executing JavaScript directly within the application environment.
When you enable watch mode or trigger a manual reload via the UDT, the tool instructs the host application to purge the existing plugin instance from its memory and re-read the manifest and source files. Because UXP isolates plugins in their own lightweight execution contexts, this teardown and rebuild happens in milliseconds.

At the center of this modern workflow is the . If you want to build plugins efficiently, mastering the tool's live-syncing capabilities—often called "hot reload" or "hot sync"—is essential. This guide covers how to leverage UDT to see your code changes instantly without restarting your host application. What is the Adobe UXP Developer Tool?
While UXP is currently dominant in Photoshop and XD, development continues to expand across other Adobe apps, with beta versions for Premiere Pro already active. Mastering the UXP Developer Tool now ensures you are ready for the future of all Adobe software extensions.
