Perhaps the most powerful feature of UDT is its built-in debugging capability. By clicking "Debug" next to a running plugin in UDT, you launch an instance of Chrome DevTools mapped directly to your plugin’s runtime environment. Through this interface, you can:
Adobe actively updates the UDT every quarter. Roadmap items include:

Unlike older frameworks like ExtendScript or the Common Extensibility Platform (CEP), UXP offers a modern approach to plugin development. It combines a powerful modern JavaScript engine with direct API access, eliminating many of the performance bottlenecks and development frustrations of previous platforms. The platform provides two complementary sets of APIs: UXP Core APIs for user interface creation, file operations, and networking; and host-specific APIs (such as Premiere APIs) for interacting directly with the application's document model and functionality.
The Adobe Unified Extensibility Platform (UXP) Developer Tools represent a transformative shift in how developers build, debug, and distribute plugins for Adobe Creative Cloud applications. As Adobe transitions away from older technologies like CEP (Common Extensibility Platform) and ExtendScript, UXP has emerged as the modern standard, bringing the power of modern web development—specifically JavaScript, HTML, and CSS—directly into the heart of professional creative workflows.
Install a UXP-compatible app, such as Adobe Photoshop (v22 or higher). Code Editor: Visual Studio Code is highly recommended. 2. Installing UDT
Click the button. UDT starts a background file-watcher on your project directory. Every time you save a .js , .css , or .html file in your code editor, the plugin reloads in Photoshop in milliseconds. Step 4: Debugging with Chrome DevTools udt create my-plugin --template panel # Create new
