Script Debugger, from Late Night Software, is a development environment built entirely around AppleScript. Where the basic Script Editor gives you a text box and a run button, Script Debugger shows you what your code is doing while it runs. You can step through a script line by line, watch values change, and inspect the objects inside the apps you are automating. For AppleScript users, it turns guesswork into a calm, visible process.

Key Features

• Full debugger with breakpoints, stepping and live inspection of variables and results
• Dictionary browser that explores the scripting terms of any scriptable application
• Explorer view that shows app objects and properties as you test commands
• Code editing with syntax coloring, completion help and clippings for common patterns
• Builds standalone script apps with code signing and notarizing support for sharing

FAQs

Is Script Debugger still supported?

The vendor retired it in 2025 and now offers past versions, including 8.0.11, as free downloads without support or warranty.

Who is Script Debugger for?

It is for Mac users who write AppleScript or JavaScript for Automation and want proper debugging instead of trial and error in a plain editor.

Can it create apps from my scripts?

Yes. It saves scripts as standalone apps, including universal builds that can be code signed and notarized for other Macs.
