Is there a way to make chrome devtools undetectable?

Question

I want to see how stuff works on a website, but each time I open Devtools (or refresh the page), I get an alert saying Devtools is open. It blocked me from using Devtools, so I want to disable this feature.

So, I searched how to "jam" google chrome Devtools and got these results:
Find out whether Chrome console is open

https://github.com/sindresorhus/devtools-detect

But I can't find any information about making Devtools Undetectable or disabling this code. Tried undocking Devtools, didn't work.

This is their code blocking me from using Devtools:

What should I do to make Devtools Undetectable?

Answer 1

In Chrome 73+ it's possible to open devtools before the page can run any code to detect it:

1. open chrome://inspect
2. click "Pages"
3. click "pause" on an entry for the tab you want to debug

Now you can inspect the page, find out how exactly it detects devtools, and defuse it. Judging by the code in your question, you can run window.uomg.create.onchange = null, but if not, set breakpoints in the code and debug it to find out a working method.

Answer 2

Based on this answer:

Find out whether Chrome console is open

The answer to your question is "No" - the sites are probably using jscript to detect the console is open and you will not be able to send back a false negative.
