How Can We Detect if the Chrome Console is Open?

Detecting Open Chrome Console: Current and Past Approaches

Determining whether the Chrome web developer console is open has been an ongoing challenge. Here are some methods that have been proposed and their current status:

Debugger

While not foolproof, the debugger-based approach outlined in Unsigned's answer appears to still function. This involves logging an Object.defineProperty on the console property and detecting its execution.

requestAnimationFrame

Muhammad Umer's requestAnimationFrame approach, written in late 2019, remains effective on Chrome 78. It offers the advantage of detecting both console opening and closing events.

function toString

Overcl9ck's comment provides an alternative method using function toString. This involves replacing the regex /./ with an empty function object. This solution continues to work in 2019.

Note that these approaches have certain drawbacks or limitations:

• The undocked console may not be detected.
• The console may not be detected if it is open on page load.
