A tool may be used to determine which WordPress theme is being used on a website. It's called WordPress Theme Detector. It examines a website's source code to see which WordPress theme is presently in use. As a consequence, WordPress Theme Detector is an application that allows you to find out all you need to know about a website's current WordPress theme and extensions. Some plugins work well on a specific page. For best results, copy the Website URL you like out of your browser and paste it into the WP detector query area.
