AutoIts

AutoIts is a colloquial term used to refer to automation scripts written in AutoIt, a freeware scripting language designed for automating the Windows graphical user interface. An AutoIts script, commonly saved with the .au3 extension, can simulate keystrokes and mouse movements, interact with windows and controls, manipulate files, and call Windows APIs. When compiled with the AutoIt compiler, these scripts can run as standalone executables (.exe) without requiring the AutoIt interpreter.

AutoIts leverage a BASIC-like syntax and include built-in functions for window management, control interaction, file I/O, and registry access. They support structures such as if statements, loops, functions, and error handling, enabling tasks ranging from simple text automation to complex installer automation and UI testing. Users can extend functionality with user-defined libraries and DLL/COM calls, and share reusable code through user-defined functions (UDFs).

Typical usage includes automating repetitive desktop tasks, automating software installation and configuration, data entry, and automated testing. AutoIts are commonly distributed as source files or compiled binaries, and can be scheduled via Windows Task Scheduler or triggered by events. Their portability across Windows versions depends on the APIs used and the level of GUI interaction involved.

Security and reliability considerations apply: because AutoIts can simulate input and modify system state, they can be flagged by antivirus software and should be obtained from trusted sources. The ecosystem includes community forums and a repository of example scripts and UDFs. Compared to other automation options, AutoIts are valued for easy GUI automation but may require more scripting than some modern tools. See also AutoIt, scripting languages, and UI automation.
