Hey everyone,

I wanted to share a little utility project I’ve been working on called CatLock. I made this because of my two orange cats who love to walk across my keyboard and cause chaos while I’m working. Previously, I used the WIN+L keyboard shortcut to lock my system, but it was annoying, especially when I was watching videos. If you’ve had similar experiences, you might find this useful. The software is completely free and zero ads.

Currently only fully supported on Windows

Features

• Lock your keyboard with a hotkey (Ctrl+L)
• Semi-transparent overlay to indicate the keyboard is locked, allowing uninterrupted viewing
• Unlock the keyboard by clicking on the overlay
• Convenient system tray menu for easy access to:
  • Adjust overlay opacity to suit your preferences
  • Enable/disable system notifications when the keyboard is locked

The code is also open source and open to contributions -

Antivirus Considerations

Some antivirus software may flag CatLock due to being bundled by PyInstaller (as seen here) or using InnoSetup to install. However, rest assured, CatLock is safe to use and does not perform any harmful actions. If you are still concerned feel free to run the code directly from github yourself. I am in the process of getting the code whitelisted by as many antivirus providers as possible so please let me know if you have any issues.

For example Microsoft has whitelisted the application -
