CapslockMute

The fastest way to mute yourself on video calls

Website capslockmute.com
Overview

What it is

A Mac utility to remap Caps Lock to the mute shortcut for Zoom, Teams, and Tandem. Because CapsLock is a large key and at your finger tips, it's much faster than clicking a button or pressing a combination of keys. It truly makes muting/unmuting muscle memory.

Intent

I need it when

Use privacy-respecting software that does not collect personal data or require internet

CapslockMute operates entirely locally on the Mac, collects no data, does not connect to the internet, and is open-source under MIT License, ensuring full privacy and transparency

Quickly mute microphone during video calls without reaching for mouse or keyboard shortcuts

CapslockMute remaps Caps Lock to instantly toggle mute in Zoom, Tandem, or Google Meet, enabling muscle-memory muting with a single key press instead of hunting for UI buttons or remembering complex shortcuts

Run a lightweight background utility that does not consume system resources

CapslockMute runs silently in the background with no CPU impact, signed and notarized by Apple, requiring only Accessibility permission to detect Caps Lock key presses

Prevent accidental audio leaks during unexpected interruptions on calls

Provides instant mute capability for sudden events (sneezing, background noise, child interruptions) by pressing Caps Lock, reducing reaction time compared to traditional mute methods

Drop

Not a fit when

  • User runs Windows or Linux; CapslockMute is macOS-only (requires macOS 10.15+)
  • User has Karabiner-Elements installed; it conflicts with CapslockMute's key remapping
  • User needs to mute in applications other than Zoom, Tandem, or Google Meet
  • User relies on Caps Lock for its standard text input function and cannot reassign it
  • User requires data collection or cloud synchronization; CapslockMute is local-only with no internet connectivity
