ExtendScript Developer Tools is a panel from Vakago Tools for executing JSX scripts and running ExtendScript commands inside Adobe applications, including After Effects and Premiere Pro. It gives you a way to inspect the Adobe API and access features beyond the documentation, such as the QE API. The plugin is aimed at plugin developers, automation engineers, and Adobe enthusiasts exploring hidden functionality across apps like Photoshop, Premiere Pro, After Effects, and Illustrator.
The ExtendScript Developer Console runs commands in the panel and lets you inspect the result, with no external tools needed. Variable Inspection works by analyzing the global namespace or clicking objects in the developer console, which helps debug extensions and explore undocumented API calls. A JSX Editor can run, load, and save JSX scripts at runtime for testing code and automating workflows.
A free trial is available to download before purchasing, and you should uninstall the trial version before upgrading. It stands out in the Adobe Exchange library as a developer-focused utility for working directly with the Adobe scripting API and learning more about return types and method parameters than the documentation offers.
