There are plenty of awesome WordPress themes and plugins around. If you run a WordPress related website, you have probably listed free scripts on your site already. WP Plugin Info Card is an awesome plugin that lets you display plugin data on your site in a beautiful fashion. It uses WordPress APIs to fetch data.
To get started, simply provide the plugin with a valid slug name, and insert the shortcode into any page. The plugin stores data for future requests to avoid affecting your page speed. You can also add as many plugins as you like in the admin page (which is perfect for plugin developers).
The shortcode for this plugin has various parameters, allowing you to customize how plugin info is shown on your site. You can change color schemes, disable the dashboard widget, and modify other settings in the back-end. This is a free tool.
