Script Debugger
Script Debugger is a macOS AppleScript development environment for writing, exploring, testing, and packaging automation scripts.
What is Script Debugger?
Script Debugger is a native macOS integrated development environment for AppleScript. It helps users write automation scripts, inspect the scripting dictionaries and live data exposed by scriptable apps, step through code line by line, and package finished scripts for use by other people. The app is aimed at Mac users, administrators, consultants, and developers who automate repetitive tasks or build AppleScript-based workflows. Key capabilities include code completion tailored to AppleScript, breakpoints and variable inspection for debugging, split-pane editing for larger scripts, and tools for exporting scripts as applets. Script Debugger was published by Mark Alldritt through Late Night Software and was designed specifically for AppleScript work on the Mac rather than general-purpose programming.
Key features
- Explore scriptable applications and inspect their scripting dictionaries and live data.
- Write AppleScript faster with code completion and code-building helpers.
- Debug scripts step by step with breakpoints, variable watches, and line-by-line execution.
- Edit long scripts more comfortably with split panes, tabs, and code folding.
- Generate code from explored application objects with drag-and-drop tools.
- Export scripts as applets and prepare them for sharing or deployment.

Safety overview
Status: Mostly safe
This is legitimate AppleScript development software for macOS. It normally needs access to the scripts and scriptable apps you choose to work with, and your automations may request macOS permissions such as Accessibility, Automation, or file access depending on what they control. Those requests are expected for scripting tools, but you should still grant only the permissions your own workflows need. Removing the app will not harm macOS, though any scripts or automation projects that depend on it may be harder to edit or debug afterward.
Recommendation: Keep Script Debugger if you write, test, or maintain AppleScript automations on your Mac. If you no longer use AppleScript development tools, you can remove it like other third-party apps; just keep any scripts or project files you still want before uninstalling.
