What is CapslockMute?

Editorial review
CapslockMute is a free, open-source macOS utility that remaps the Caps Lock key to toggle mute in video conferencing apps like Zoom, Google Meet, and Tandem. Because Caps Lock is a large, easily accessible key, it provides the fastest way to mute and unmute during video calls without searching for on-screen buttons or remembering keyboard shortcuts. The app is Apple-signed and notarized, runs silently in the background with minimal resources, collects no data, and never connects to the internet. Released under the MIT license, it requires macOS 10.15 Catalina or later and Accessibility permission on first launch.

Available on: macOS
