If you want, I can:
A simple dropdown menu allows you to choose which host application (and which specific version, including Beta builds) you want to load the plugin into.
When launching the Chrome DevTools debugger through UDT, breakpoints would routinely show as "unbound" (grayed out). This made step-by-step troubleshooting impossible without inserting hardcoded debugger; statements directly into source code.
that addresses common issues found in the official Adobe package [11, 15]. @adobe-fixed-uxp/uxp-devtools-cli
Note: If the Developer Tool fails to detect the host app, restart both the Developer Tool and host app; ensure both run with same user privileges; verify host app has UXP enabled. adobe uxp developer tools fixed
The most significant "fix" addresses the reliability of the connection between the developer tool and the host application (Photoshop).
While the GUI offers a user-friendly starting point, many advanced workflows rely on the CLI, which has received critical updates we'll explore next.
: Automatically flags common breaking issues like trailing commas in manifest.json or mismatched manifest versions that can break file permission dialogs.
These community projects are not just stop-gaps; they have become essential parts of the development pipeline for many serious plugin creators. They demonstrate a healthy, resilient ecosystem, but also highlight the gaps in Adobe's official offerings that still need to be closed. If you want, I can: A simple dropdown
UDT now includes a feature – a sandboxed environment that allows developers to experiment with UXP APIs without scaffolding a full project on disk. The Playground provides a code editor with tabs for HTML, CSS, JavaScript, and Manifest files. Changes are automatically reflected in the host application (except manifest changes, which require reload). When prototyping is complete, you can export the entire code into a folder that can be loaded as a regular plugin.
To take advantage of these stability fixes, follow this clean installation and configuration workflow. Step 1: Install the Latest Prerequisites
Despite Adobe's internal use of UXP for some of its own features, there is still no public UXP API or developer tooling available for Adobe Illustrator as of May 2026 . The platform remains in a state of "coming soon," with no official timeline for release. For new Illustrator plugin development, CEP remains the only viable option, though Adobe has assured developers that CEP will continue to be supported for the foreseeable future while the transition occurs. This fragmented support is a major factor in the decision-making process for any plugin developer targeting the Creative Cloud suite.
Historically, starting a new Adobe panel required downloading bloated boilerplate repositories from GitHub, stripping out old code, and trying to figure out which configuration fit the latest software update. The UDT Solution that addresses common issues found in the official
Which (Photoshop, InDesign) are you targeting?
Add a panel inside the UXP Developer Tools (UDT) that mirrors browser DevTools’ Elements panel but is purpose-built for UXP’s restricted DOM and Spectrum UI components.
“I used to restart InDesign 20 times a day. After the February patch, I haven't restarted in a week. The live reload actually updates my React components without dropping state.” –
