🚫 SiteBlocker – A Simple Website Blocker for Windows (Python + GUI + .exe)

#siteblocker #python #exe #github

Tired of distractions while working? Want to prevent access to specific websites from your Windows machine?

I built a small utility app called SiteBlocker that lets you easily block or unblock websites using a graphical interface — and yes, it's packaged as a standalone .exe` for Windows!

🧠 What It Does

SiteBlocker.exe modifies your system’s hosts file to redirect unwanted domains to 127.0.0.1. That means blocked websites won't load in any browser on your computer.

No command line, no config files — click to block or unblock.

🔧 Features

  • ✅ Block websites by entering the domain (e.g., facebook.com)
  • ✅ View all currently blocked websites
  • ✅ Unblock any selected website from the list
  • ✅ Clean, simple GUI (built with Tkinter)
  • ✅ Built as a single .exe using PyInstaller

Download

  1. Download executable file: https://github.com/mahmud-r-farhan/site-blocker/releases/download/v1.0.1/SiteBlocker.exe

  2. Github
