FastAutoClicker

A high-performance Windows autoclicker built with Python. Uses direct Windows API calls via ctypes to achieve 1,000-3,000+ clicks per second with no third-party clicking libraries required.

Requirements

• Windows 10 / 11
• Python 3.6+
• No admin rights required

---

Quick Start

Run directly with Python

python autoclicker_gui.py

Build a standalone .exe

Double-click build.bat and the finished executable will be at:

dist\AutoClicker.exe

No Python installation needed to run the .exe.

GUI Overview

Element	Description
CPS display	Live clicks-per-second readout, updates 10x per second
Total clicks	Running total since last reset
START / STOP button	Toggles clicking on/off, turns red while active
Reset Counter	Resets the total click counter to zero
Status bar	Green = running, grey = stopped

---

Hotkeys

Key	Action
F6	Start / Stop clicking
F7	Quit the application

Hotkeys work globally, even when the AutoClicker window is not focused.

Project Files

autoclicker_gui.py   # Main application (GUI + click engine)
package.bat            # One-click build script -> dist\AutoClicker.exe

How It Works

• Calls SendInput directly via the Windows API, the lowest-overhead clicking method available without a kernel driver
• Mouse down + up are sent in a single SendInput(2, ...) call (one syscall per click)
• Input structs are pre-allocated at startup and reused every iteration, with zero allocation overhead in the hot loop
• The click engine runs on a dedicated thread, keeping the GUI fully responsive

---

Building the Exe

build.bat runs the following command:

python -m PyInstaller autoclicker_gui.py --onefile --noconsole --name AutoClicker --clean

Flag	Effect
--onefile	Bundles everything into a single portable .exe
--noconsole	No terminal window appears when launched
--clean	Clears PyInstaller cache before building

Build output is in the dist\ folder. The build\ folder and AutoClicker.spec file are intermediates and can be deleted after building.

Notes

• The AutoClicker window stays always on top so it remains visible while clicking in other applications.
• Actual CPS depends on your CPU speed and Windows scheduler, with a typical range of 1,000-3,000 clicks/sec.
• Some anti-cheat systems may detect high-frequency SendInput calls. Use responsibly.
