How to make a Python auto clicker?

Last Updated :20 May, 2025

Auto-clickersare tools that simulate mouse clicks automatically at a given location and interval. Whether you're automating repetitive tasks in games, productivity applications, or testing graphical user interfaces (GUIs), creating an auto-clicker in Python is both a fun and practical project. In this article, we’ll walk you through building a fully functional auto-clicker using the pynput module to monitor keyboard input and simulate mouse clicks.

Requirements

We’ll be using the pynput module, a cross-platform library for controlling and monitoring input devices (mouse/keyboard). To install pynput, run the following command in your terminal or command prompt:

pip install pynput

After installing this module, we need to verify whether it has been installed correctly. Open your Python shell or IDLE and type:

Let's now proceed with the code that is required to build anAuto-clickerusing Python. Follow the below steps to create an auto-clicker:

Step 1:Start by importing the necessary modules. These allow us to work with time delays, threads for background execution and to control keyboard and mouse inputs.

Python

importtimeimportthreadingfrompynput.mouseimportButton,Controllerfrompynput.keyboardimportListener,KeyCode

Step 2:We set up key variables that determine how the clicker behaves:

d: Time gap between each click.
btn:Which mouse button to click.
start_key:Hotkey to start or stop clicking.
exit_key:Hotkey to exit the program.

Python

# Config variablesd=0.001btn=Button.left# Hotkeysstart_key=KeyCode(char='a')exit_key=KeyCode(char='b')

Step 3:We use Python’sthreading.Thread to run the auto-clicker in the background so it doesn't block keyboard input.

Python

classAutoClicker(threading.Thread):def__init__(self,d,btn):super().__init__()self.d=d# Delayself.btn=btn# Buttonself.clicking=Falseself.active=Truedefstart_click(self):self.clicking=Truedefstop_click(self):self.clicking=Falsedefexit(self):self.stop_click()self.active=Falsedefrun(self):whileself.active:whileself.clicking:mouse.click(self.btn)time.sleep(self.d)

Step 4: We create a Controller instance to simulate mouse actions, and then start the thread we just defined.

Python

mouse=Controller()c=ClickMouse(d,btn)c.start()

Step 5:This function listens for key presses. If the user presses a, the clicker toggles on or off. Pressing b exits the application.

Python

defon_press(k):ifk==start_key:ifclicker.clicking:clicker.stop_click()print("[INFO] Clicker Stopped.")else:clicker.start_click()print("[INFO] Clicker Started.")elifk==exit_key:clicker.exit()print("[INFO] Exiting.")returnFalse# Stop listener

Step 6:Creating an instance for the mouse controller, then createClickMouse thread. Start the instance to move into the loop inside the run method.

Python

# instance of mouse controller is createdmouse=Controller()click_thread=ClickMouse(delay,button)click_thread.start()

Step 7:Now we start the keyboard listener, which keeps the program running and listens for hotkey presses.

Python

withListener(on_press=on_press)aslistener:listener.join()
