Tailwind CSS Media Query Inspector is a free Chrome extension developed by OwenMelbourne.com. It falls under the category of Browsers and is classified as an Add-ons & Tools subcategory. This handy tool allows users to easily see which breakpoint they are currently in without cluttering up their UI.

The extension adds a simple icon to your Chrome toolbar that displays the current media query you are within. By default, it comes with the TailwindCSS media queries, but you have the flexibility to configure as many media query rules as you like from the extension.

It's important to note that this extension does not attempt to parse the CSS from a website. Instead, it simply monitors the media queries you enter. In the future, the upcoming V2 version will allow you to configure different media queries per domain, providing even more customization options.
