In your host application (e.g., Photoshop), go to . adobe uxp developer tools
You can download UDT directly through the under the "Developer" section, or via Adobe's prerelease and developer portals. Core Features of UDT:

By providing native Chrome DevTools integration, instantaneous hot-reloading, and an intuitive project management interface, Adobe has successfully modernized its extensibility platform. For developers, this translates to faster iteration cycles, fewer bugs, and the ability to build incredibly rich, performant tools that empower creatives worldwide.

Use JavaScript and the UXP API to interact with the document (e.g., changing layers, applying filters).
For years, building plugins for Adobe products like Photoshop and Illustrator meant learning two different codebases. You had CEP (Common Extensibility Platform) for panels, and a separate set of scripts for automation. It was powerful, but fragmented. It creates a seamless Hot Module Replacement (HMR)
index.js : The JavaScript file handling logic and interactions with the host app's API.
Every UXP plugin requires a manifest.json file at its root. This file tells UDT and the host application how to handle your plugin. It defines: Minimum required host application versions.
The true power of UDT lies in its robust debugging capabilities. If you have ever struggled with the limitations of alert() debugging in ExtendScript, UDT will feel like a massive upgrade. Using Chrome DevTools
