She watched as telemetry—anonymous and ethical—showed adoption climbing. Threads lit up with gratitude and suggestions.
Teams still reliant on CEP should migrate to UXP to take advantage of the streamlined debugging and packaging workflows offered by the UXP Developer Tool.
As soon as you save a .js , .css , or .html file in your editor (e.g., VS Code), UDT automatically reloads the plugin in the host app. You see the changes immediately 1.2.2.

Master the Adobe UXP Developer Tool: Why Hot Reload and Real-Time Debugging Are Game Changers
Ultimately, the "hot" status of the Adobe UXP Developer Tool is a sign of vitality. It signals an industry moving toward a standardized, performant model for extensibility. The tool is the crucible in which the next generation of creative workflows is being forged. While the transition generates heat in the form of learning curves and beta-stage instability, the result promises a cooler, faster, and more intuitive experience for both the developers building the tools and the creatives using them. The heat is not just a sign of friction, but of momentum.
Do not guess why a hot reload didn't render your layout correctly. Next to the "Watch" button in UDT, you will find the button. Clicking this opens a dedicated Chrome DevTools window. Combine real-time hot reloading with the DevTools Element Inspector to test temporary CSS styles on the fly, and use the Console tab to track state updates as they happen.
