While UXP supports modern build tools like Webpack and Vite, the live-reload features often clashed with UDT's internal folder-watching mechanics. The resolved codebase handles file-system watching more gracefully, preventing recursive loop crashes during rapid code iterations.
Transparency is key. While the headline is positive, three minor issues remain, though they are no longer blockers:
1. What’s Fixed in the Latest Adobe UXP Developer Tools (2026)
The local UDT application runs on an Electron framework. When developers updated their local system Node.js environments to newer LTS versions (such as Node 18 or Node 20), internal dependency conflicts occasionally broke the command-line interface ( uxp-cli ) or caused the UDT GUI to crash on boot. 3.

To appreciate the impact of these fixes, it helps to understand why the Adobe UXP Developer Tools (UDT) application is so vital.
Now, edit your index.html or main.js . Save. Watch the Adobe app update in under 200ms without losing undo history.
Live reloading is essential for modern UI development, allowing developers to see CSS and HTML changes instantly without manual refreshing. While UXP supports modern build tools like Webpack

The moment you save a .js or .css file in your IDE (like VS Code), UDT instantly pushes the updates to the live panel inside Photoshop.
If you have delayed migrating your legacy CEP panels due to UDT instability, now is the time to transition. UXP offers native rendering speed, meaning your UI elements will no longer lag or drop frames. Use the fixed UDT to load your old logic over to the modern JavaScript engine safely, knowing your debugger will accurately catch migration errors.

In theory, UDT offered "Hot Reload" for manifest changes and UI updates. In practice, developers reported that after 3-4 reloads, the plugin would freeze, forcing a full restart of the host application (e.g., Photoshop). This made iterative UI design a 45-minute ordeal for what should have been a 5-minute task.

Plugin loading times have been optimized, making the "save-and-see-changes" workflow much faster.
Currently, debugging UXP plugins involves relying heavily on console.log , manual element inspection, and guesswork when UI elements don’t behave as expected. There’s no visual way to inspect the UXP DOM, view real-time style changes, or see layout boundaries — making UI debugging slow and frustrating.
