For everyone using or considering this detector script, can you comment on how you use it / plan to use it?

Chrome is considering removing the detection technique used at the heart of this script and we want to understand how it's used in the wild. (Meanwhile, there are chrome extension APIs to detect when devtools opens/closes)

Thank you!

First of all, awesome job! :) Thanks for creating this.

The demo page always tells me that the devtools are docked (when they are open). I didn't do thorough debugging but here are the values when paused at the if() condition inside height() test:

window.outerHeight
1000

zoom
1

window.outerHeight
1000

window.innerHeight
938

window.chrome.inspector._windowHeightOffset
-938

Regarding this site, console.profiles is removed from chromium latest code.

Chrome 29 beta already does not have console.profiles.

It would be nice to figure out how to do this in IE too. One way to tell, is that window.console is undefined until the dev tools have been opened. However it stays defined, after being closed, so I have no idea, how to detect closing. Perhaps have a look at the HTML code school source, mentioned on SO.

I've been writing some HTML5 based quizzes - this is a good way to tell if someone is trying to cheat. Thanks for the great idea.

Doesn't seem to be anything out there yet: https://chrome.google.com/webstore/search-extensions/web%20inspector%20events.

The great folks on HN have been finding a number of false positives generated by the window check.

window.outerHeight > (window.innerHeight + window.chrome.inspector._windowHeightOffset) || window.outerWidth > window.innerWidt

• Downloads bar being open
• Browser zoomed
• Window state (unconfirmed)

Not sure if you're already aware of it (or don't really care because it's Canary), but Canary's inspector is always detected as being in a "docked" state regardless of whether it is docked or undocked.
