How to make Chrome always launch with remote-debugging-port flag

Question

I know I can launch chrome the following way to open a remote debugging port at 9222 port -

chrome.exe --remote-debugging-port=9222 

But I want to setup Chrome such that whenever it is launched by any other application, it always opens with the remote debugging option enabled. Will a custom profile work?

I want to achieve it as there a desktop app that would be launching chrome on clicking its button. I want to control that chrome session.

Answer 1

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.

Answer 2

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.
