Repository metrics are context, not quality scores. Active installations measure adoption and can strongly reflect a plugin’s age and historical popularity. Ratings, recent updates and “Tested up to” metadata also do not guarantee modern code, error-free operation, security, feature completeness or suitability for a particular site. Why active installs don’t tell the whole story →
WP PlugIndex currently records Easy Responsive Test version 3.0.0 as active, updated 1mo ago and tested up to WordPress 7.0.
Overview
About this plugin
Easy Responsive Test (ERT) is an essential tool for WordPress administrators and developers who need to verify how a site looks at different screen dimensions. After activation, the plugin creates a dedicated preview page that loads your site inside a resizable iframe with a toolbar for switching between preset and custom viewport sizes.
You do not need to resize your browser window every time you test responsiveness. Install ERT, configure your sizes, and preview your site from the admin settings screen.
Features
Test your site at multiple screen sizes from a single preview page
Six common viewport sizes included out of the box (320×480 through 1280×1024)
Add unlimited custom height:width pairs from the settings page
Customize toolbar background and foreground colors with the WordPress color picker
One-click “Check Your Site” link from the ERTP Settings admin page
Demo page is created automatically on activation and hidden from the Pages list
Settings link on the Plugins screen for quick access
Admin bar is hidden on the preview page for an accurate front-end view
Settings and preview restricted to users with the manage_options capability
How it works
Activate the plugin. A private preview page titled “ERTP Site Check” is created automatically.
Open ERTP Settings in the WordPress admin menu to configure viewport sizes and toolbar colors.
Click Check Your Site to open the preview page in a new tab.
Use the toolbar to switch between configured viewport sizes while your live site loads inside the iframe.

480 x 600
540 x 960
