This comprehensive guide explores everything that has been “fixed” – from resolved bugs and enhanced debugging capabilities to improved host application support and performance optimizations. Whether you are migrating legacy CEP (Common Extensibility Platform) extensions or building new UXP plugins from scratch, this resource will help you understand the current state of Adobe’s extensibility platform and how to make the most of its developer tools.

The Adobe UXP Developer Tools have come a long way. The fixes documented here – from ResizeObserver APIs and IntersectionObserver support to Load & Watch, CLI tooling, and the Playground – represent genuine progress. Platform adoption is accelerating across Photoshop, InDesign, and Premiere Pro. Known issues are acknowledged transparently, with active timelines for resolution.

For developers evaluating the platform in 2026, the question is no longer “is UXP ready?” but rather “which application’s UXP support should I target first?”. The tools are fixed, the APIs are modern, and the future is clear: UXP is the foundation for Adobe extensibility, and the UXP Developer Tool is the key that unlocks it. Happy developing.
To appreciate the impact of these fixes, it helps to understand why the Adobe UXP Developer Tools (UDT) application is so vital.
When a native API call errored out deeply within the UXP runtime, UDT would occasionally drop the debugger connection entirely without outputting a meaningful stack trace to the console.
