chrome-cli

Overview

chrome-cli is a command line utility for controlling Google Chrome compatible browsers on OS X. It is a native binary that uses the Scripting Bridge to communicate with Chrome. chrome-cli has been tested with the following browsers:

  • Chrome
  • Chrome Canary
  • Chromium
  • Brave
  • Vivaldi
  • Edge
  • Arc

Other browsers

By default chrome-cli communicates with Chrome, but you can use it with other browsers by settings the CHROME_BUNDLE_IDENTIFIER environment variable. I.e. to use chrome-cli with Brave you can run the following command:

CHROME_BUNDLE_IDENTIFIER="com.brave.Browser" chrome-cli list tabs

Check the scripts directory for some convenient wrappers.

How do I find the bundle identifier?

The following command will print out the bundle identifier for Brave

mdls -name kMDItemCFBundleIdentifier -raw /Applications/Brave\ Browser.app

brew install chrome-cli
