Answer 1

For mac, I made a simple application that launches chrome with the --remote-debugging-port for me. Mathias Bynens has a wonderful post on how to do this (which is where I got the idea). He even includes a (forked) script that can do most of it for you, but the basics are really simple.

1. Make a directory in your applications folder with the following structure <new app name>/Contents/MacOS:

   mkdir -p /Applications/Chrome\ Debugger.app/Contents/MacOS
   

2. Create your script file and make it executable (its name need to match the top folder name):

   cd /Applications/Chrome\ Debugger.app/Contents/MacOS
   touch Chrome\ Debugger
   sudo chmod +x Chrome\ Debugger
   

3. Edit the new file with your editor of choice (your path to chrome may be different):

   #!/usr/bin/env bash
   /Applications/Google\ Chrome.app/Contents/MacOS/Google\ Chrome --remote-debugging-port=9222&
   

And that's about it. You can add a custom icon if you want to make it easier to find (copy your new icon > right click the new app > Get Info > click the current icon in the top left > paste the new icon over current icon), but the app will work fine without it.

I have figured out a way to solve my problem statement. I am posting it as an answer as it may help someone else with similar problem statements.

If you are on Windows, go to registry editor and search this command

Computer\HKEY_CLASSES_ROOT\ChromeHTML\shell\open\command

Modify the key with the following -

"C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" --remote-debugging-port=9222 -- "%1"

If you want to play with Chrome, put --incognito if you always want to launch Chrome in incognito mode.

Caution: Please backup your registry before playing with it.

I can't add comments yet, But David Mann's answer is out of date for MacOS.

Thankfully only one slight change is needed; Add the bash shebang to the Chrome Debugger script.

#!/bin/bash
/Applications/Google\ Chrome.app/Contents/MacOS/Google\ Chrome --remote-debugging-port=9222&

this update for mac users was found here: Enable remote debugging on Chrome by default on mac?

Nat Khun also went to the trouble of crafting a .dmg to allow for a "normal" installation procedure for mac users. His repo can be found here: https://github.com/natkuhn/Chrome-debug/

be sure to give him a star. I did!

Rather than editing the registry, you can simply append the flag directly within the program properties by right clicking on the Chrome icon and adding...

--remote-debugging-port=9222 -- "%1" 

...onto the end of the target field.
