Disqus is a third-party comment management system. However it loads its javascript code on every page indiscriminately. This code should only be loaded on pages where the comments form is actually going to load. Otherwise your site is wasting cycles including javascript that isn’t going to be used.
This plugin stops the <a href="https://wordpress.org/plugins/disqus-comment-system/" rel="ugc">Disqus plugin</a> from loading its javascript on pages or posts where comments are closed. If comments are closed and there are no existing comments already, the JavaScript will be stopped from loading. Note that to avoid breaking the existing functionality, the JavaScript will still load if comments are closed but there are already some comments on a page/post.

The Disqus Recent Comments Widget plugin will create a configurable widget that will allow you to display comments in any widgetized area of your theme like sidebars and footers.
You can customize the comment length and date format, filter users and choose from three different markup templates, among other things. The plugin has full support for custom markup defined with register_sidebars() and should integrate smoothly with most themes in the wp.org repository.
We try to be very proactive and responsive with support. So, if you have any issues, please post in the support forums and we’ll do our best to resolve your issue promptly.
