Auto-clickers are 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

Installation of pynput module

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

Step by step implementaion

Let's now proceed with the code that is required to build an Auto-clicker using 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 
import time
import threading

from pynput.mouse import Button, Controller
from pynput.keyboard import Listener, 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 variables
d = 0.001             
btn = Button.left     

# Hotkeys
start_key = KeyCode(char='a')  
exit_key = KeyCode(char='b')


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

Python 
class AutoClicker(threading.Thread):
    def __init__(self, d, btn):
        super().__init__()
        self.d = d                # Delay
        self.btn = btn            # Button
        self.clicking = False
        self.active = True

    def start_click(self):
        self.clicking = True

    def stop_click(self):
        self.clicking = False

    def exit(self):
        self.stop_click()
        self.active = False

    def run(self):
        while self.active:
            while self.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 
def on_press(k):
    if k == start_key:
        if clicker.clicking:
            clicker.stop_click()
            print("[INFO] Clicker Stopped.")
        else:
            clicker.start_click()
            print("[INFO] Clicker Started.")
    elif k == exit_key:
        clicker.exit()
        print("[INFO] Exiting.")
        return False  # Stop listener


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

Python 
# instance of mouse controller is created
mouse = 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 
with Listener(on_press=on_press) as listener:
    listener.join()

Full Source code

Python 
import time
import threading

from pynput.mouse import Button, Controller
from pynput.keyboard import Listener, KeyCode

# Config variables
d = 0.001             # Delay between clicks
btn = Button.left     # Mouse button to click

# Hotkeys
start_key = KeyCode(char='a')  # Start/stop key
exit_key = KeyCode(char='b')   # Exit key

class AutoClicker(threading.Thread):
    def __init__(self, d, btn):
        super().__init__()
        self.d = d
        self.btn = btn
        self.clicking = False
        self.active = True

    def start_click(self):
        self.clicking = True

    def stop_click(self):
        self.clicking = False

    def exit(self):
        self.stop_click()
        self.active = False

    def run(self):
        while self.active:
            while self.clicking:
                mouse.click(self.btn)
                time.sleep(self.d)

# Create mouse controller
mouse = Controller()

# Create and start the auto-clicker thread
clicker = AutoClicker(d, btn)
clicker.start()

# Keyboard listener function
def on_press(k):
    if k == start_key:
        if clicker.clicking:
            clicker.stop_click()
            print("[INFO] Clicker Stopped.")
        else:
            clicker.start_click()
            print("[INFO] Clicker Started.")
    elif k == exit_key:
        clicker.exit()
        print("[INFO] Exiting.")
        return False  # Stop listener

# Start listening for keyboard events
with Listener(on_press=on_press) as listener:
    listener.join()

Now let's execute the python program we've written and then press the start (a) and stop (a) keys in order to initiate the auto clicker.
