Developer Tools Blocker is a free WordPress plugin designed to enhance security by restricting non-admin users from accessing developer tools. It effectively blocks the use of inspect element and common keyboard shortcuts like F12 while allowing full access to administrators. Additionally, it provides an option to disable right-click functionality for non-admin users, ensuring that sensitive site information remains protected. The plugin is particularly useful for developers wanting to safeguard their work from unauthorized scrutiny.

The latest version, 3.0, introduces improved speed and accuracy, functioning seamlessly across most browsers. It features advanced lag detection to identify when the browser console is opened, providing a robust layer of protection against potential spying attempts. Tests confirm that the plugin performs reliably even under heavy site loads, ensuring that legitimate users are not affected while keeping non-admin interactions secure.
