AutoIt is a freeware BASIC-like scripting language designed for automating the Windows GUI and general scripting.

It uses a combination of simulated keystrokes, mouse movement, and window/control manipulation in order to automate tasks in a way not possible or reliable with other languages (e.g. VBScript and SendKeys).

AutoIt is also very small, self-contained, and will run on all versions of Windows out-of-the-box with no annoying “runtimes” required!

It was initially designed for PC “roll out” situations to reliably automate and configure thousands of PCs. Over time it has become a powerful language that supports complex expressions, user functions, loops, and everything else that veteran scripters would expect.

It has been designed to be as small as possible and stand-alone with no external .dll files or registry entries required making it safe to use on Servers. Scripts can be compiled into stand-alone executables with Aut2Exe.

Also supplied are a combined COM and DLL version of the app called AutoItX that allows you to add the unique features of this program to your own favorite scripting or programming languages! It has a BASIC-like syntax which means that most people who have ever written a script or used a high-level language should be able to pick it up easily.

The toolis a very small and standalone application with no reliance on massive runtimes like .NET or VB. All you need to run the scripts are the main the app executable (AutoIt3.exe) and the script. Scripts can also be encoded into standalone executables with the built-in script compiler Aut2Exe.

Much time has been spent optimizing the keystroke and mouse simulation functions to be as accurate as possible on all versions of Windows. All the mouse and keyboard routines are highly configurable both in terms of simulation “speed” and functionality.

Features and Highlights
  • Easy to learn BASIC-like syntax
  • Simulate keystrokes and mouse movements
  • Manipulate windows and processes
  • Interact with all standard windows controls
  • Scripts can be compiled into standalone executables
  • Create Graphical User Interfaces (GUIs)
  • COM support
  • Regular expressions
  • Directly call external DLL and Windows API functions
  • Scriptable RunAs functions
  • Detailed helpfile and large community-based support forums
  • Compatible with Windows XP / 2003 / Vista / 2008 / Windows 7 / 2008 R2 / Windows 8 / 2012 R2 / Windows 10 / Windows 11
  • Unicode and x64 support
  • Digitally signed for peace of mind
  • Works with Windows Vista’s User Account Control (UAC)
How to Use
  • Write a Script – Use SciTE (included with AutoIt) to create a new .au3 script.
  • Basic Automation – Automate keystrokes, mouse movements, and window interactions using functions like Send(), MouseClick(), and WinActivate().
  • Run the Script – Execute your script by double-clicking the .au3 file or running it from the command line.
  • Compile to EXE – Convert your script into an executable using the AutoIt Compiler (Aut2Exe).
  • Use MsgBox for Testing – Display messages with MsgBox() to debug or prompt user interactions.
  • Control Windows & UI – Interact with GUI elements using ControlClick(), ControlSend(), and WinWait().
  • Loops & Conditions – Use For, While, and If statements to add logic and repetition.
  • Include External Libraries – Extend functionality using #include directives for additional libraries.
  • Secure with Obfuscation – Use script obfuscation (Obfuscator.exe) to protect source code when distributing compiled scripts.
