Well that is poopy. Is there a way I can “stealth” open dev tools on all sites? I like to see network requests in a lot of places, but don’t like to think the server will change their responses based on my local actions.
There are a couple of ways they can try to detect devtools being opened. As the sibling comment implies, the most popular way is to detect a sudden viewport resize, and you can avoid that by ensuring your devtools are set to open in a new window before opening them.
The only other ways I'm aware of are:
- Detecting the keyboard shortcut, ⌘⌥i or equivalent, which you can avoid by using the browser menu, and
- More riskily, evaluating a `debugger` statement and detecting whether evaluation paused. I'm not sure you could do anything about this one, but it would certainly be obvious to you whether it was happening.
