Theme Inspector is a free WordPress plugin that enhances theme development by providing essential technical information right on the pages and posts. It offers quick access to details like post IDs, slugs, and taxonomy terms, allowing developers to streamline their workflow effectively. By revealing active conditional tags and identifying template files for each view, this tool significantly boosts development efficiency.

This plugin is particularly useful when paired with the WP Template Hierarchy Document, as it provides deeper insights into theme structures. To maintain security, Theme Inspector is accessible only to logged-in Administrators, ensuring that sensitive information remains protected. The plugin is conveniently located in the admin toolbar for easy access during site management.
