Devtools Status Detector is a free Chrome extension developed by vothaison.vietnam. This extension is designed specifically for Javascript developers, providing them with a way to detect whether Chrome Devtools is open or closed on the current page.

The main purpose of Devtools Status Detector is to raise an event named 'devtoolsStatusChanged' on the window.document element whenever Chrome Devtools opens or closes. This allows developers to execute specific code based on the status of Devtools.

To use the extension, developers can add an event listener using the provided example code. The event listener will trigger when the 'devtoolsStatusChanged' event occurs, providing the status of Devtools as the event detail. Developers can then execute their code based on whether Devtools is opened or closed.

Devtools Status Detector is a valuable tool for Javascript developers who rely on Chrome Devtools for debugging and inspecting web pages. By providing a simple way to detect the status of Devtools, developers can enhance their workflow and streamline their debugging process.
