Automatically open Chrome developer tools when new tab/new window is opened

On opening the developer tools, with the developer tools window in focus, press F1. This will open a settings page. Check the "Auto-open DevTools for popups".

This worked for me.

UPDATE 2:

See this answer . - 2019-11-05

You can also now have it auto-open Developer Tools in Pop-ups if they were open where you opened them from. For example, if you do not have Dev Tools open and you get a popup, it won't open with Dev Tools. But if you Have Dev Tools Open and then you click something, the popup will have Dev-Tools Automatically opened.

UPDATE:

Time has changed, you can now use --auto-open-devtools-for-tabs as in this answer – Wouter Huysentruit May 18 at 11:08

OP:

I played around with the startup string for Chrome on execute, but couldn't get it to persist to new tabs. I also thought about a defined PATH method that you could invoke from prompt. This is possible with the SendKeys command, but again, only on a new instance. And DevTools doesn't persist to new tabs.

Browsing the Google Product Forums, there doesn't seem to be a built-in way to do this in Chrome. You'll have to use a keystroke solution or F12 as mentioned above.

I recommended it as a feature. I know I'm not the first either.

There is a command line switch for this: --auto-open-devtools-for-tabs

So for the properties on Google Chrome, use something like this:

"C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" --auto-open-devtools-for-tabs

Here is a useful link: chromium-command-line-switches

On a Mac: Quit Chrome, then run the following command in a terminal window:

open -a "Google Chrome" --args --auto-open-devtools-for-tabs

Under the Chrome DevTools settings you enable:

Under Network -> Preserve Log Under DevTools -> Auto-open DevTools for popups

With the Developer Tools window visible, click the menu icon (the three vertical dots in the top right corner) and click Settings.

Under Dev Tools, check the Auto-open DevTools for popups option

F12 is easier than Ctrl+Shift+I

If you use Visual Studio Code (vscode), using the very popular vscode chrome debug extension (https://github.com/Microsoft/vscode-chrome-debug) you can setup a launch configuration file launch.json and specify to open the developer tool during a debug session.

This the launch.json I use for my React projects :

{
  "version": "0.2.0",
  "configurations": [
    {
      "type": "chrome",
      "request": "launch",
      "name": "Launch Chrome against localhost",
      "url": "http://localhost:3000",
      "runtimeArgs": ["--auto-open-devtools-for-tabs"],
      "webRoot": "${workspaceRoot}/src"
    }
  ]
}

The important line is "runtimeArgs": ["--auto-open-devtools-for-tabs"],

From vscode you can now type F5, Chrome opens your app and the console tab as well.

Answer for 2021:

Open the Developer Tool (CTRL+SHIFT+I on Windows) Click the "Gear" icon. THe new Settings window will appear.

"Auto-open DevTools for popups" is now under "Preferences" section.

Use --auto-open-devtools-for-tabs flag while running chrome from command line

/Applications/Google\ Chrome.app/Contents/MacOS/Google\ Chrome --auto-open-devtools-for-tabs

https://developers.google.com/web/tools/chrome-devtools/open#auto

I came here looking for a similar solution. I really wanted to see the chrome output for the pageload from a new tab. (a form submission in my case) The solution I actually used was to modify the form target attribute so that the form submission would occur in the current tab. I was able to capture the network request. Problem Solved!

Anyone looking to do this inside Visual Studio, this Code Project article will help. Just add "--auto-open-devtools-for-tabs" in the arguments box. Works on 2017.

Yep,there is a way you could do it

Right click->Inspect->sources(tab) Towards Your right there will be a "pause script execution button"

I hope it helps!Peace

P.S:This is for the first time.From the second time onwards the dev tool loads automatically

You can open dock view settings and adjust the window as you want. Screenshot attached.

You can open Dev Tools (F12 in Chrome) in new window by clicking three, vertical dots on the right bottom corner, and choose Open as Separate Window.
