AppleScript vs. FastScript vs. FoldersSynchronizer vs. Python Comparison Chart

AppleScript is a scripting language created by Apple. It allows users to directly control scriptable Macintosh applications, as well as parts of macOS itself. You can create scripts, and sets of written instructions, to automate repetitive tasks, combine features from multiple scriptable applications, and create complex workflows. AppleScript 2.0 can use scripts developed for any version of AppleScript from 1.1 through 1.10.7, any scripting addition created for AppleScript 1.5 or later for macOS, and any scriptable application for Mac OS v7.1 or later. A scriptable application is one that can be controlled by a script. For AppleScript, that means being responsive to inter-application messages, called Apple events, sent when a script command targets the application. AppleScript itself provides a very small number of commands, but it provides a framework into which you can plug many task-specific commands, those provided by scriptable applications and scriptable parts of macOS.

FoldersSynchronizer is a nifty and popular utility for macOS (Apple Silicon and Intel) which synchronizes and backs-up files, folders and disks. You can choose one or more pairs of files, folders or disks then FS will synchronize or backup those exactly. FS lets you organize your sync and backup on several sessions you can save to a file for a later reuse. On each session you can apply special options like Timers, Multiple pairs of folders, Filters, Exclude Items, Auto-Mount local and remote volumes, launch your own AppleScripts, set how to resolve Conflicts, execute an incremental or an exact copy, include locked files... FS can display a preview panel listing all the files FS is going to copy, replace and delete. FS can save a log file or send it to a custom email address, and it can sync and automatically quit the application… FoldersSynchronizer has been successfully tested on macOS 14 Sonoma. Previous versions for previous macOSs, for Intel and PPC are available too.
