Bash script that checks for apps that use Electron. Detailed a bit more here: https://cameronnokes.com/blog/how-to-know-if-a-desktop-app-uses-electron/

check-for-electron-apps.sh

#!/bin/bash

target="${1:-/Applications}"

check() {
  stat "$1/Contents/Frameworks/Electron Framework.framework" &> /dev/null
  if [[ $? = 0 ]]; then
    echo "$1 uses Electron"
  fi
}

export -f check

find "$target" -maxdepth 2 -type d -name "*.app" -exec bash -c 'check "{}"' \;

# give this script executable permissions (chmod +x), then run. By default it'll check /Applications

Thanks for the suggestion darzo! I just made /Applications the default. Should have done that from the outset.

This is brilliant !
Saw your post https://cameronnokes.com/blog/how-to-know-if-a-desktop-app-uses-electron/

As some Hackintosh machines can sometimes lag due to Electron apps, I needed to find out how to determine which apps are the culprit, your site link was one of the top hits and the best! Hint, hint - Hackintosh / cursor lag may be tags to add to that page.

Also, while I overstate the comment, entering "/Applications" as a parameter for the script was sufficient to output the apps, adding the suggestion in the echo might save someone a few seconds.
