Disqus is an external comment system that can be easily integrated with any website. It offers login through popular social media platforms.

Why Disqus?

  • Social media login - Twitter, Facebook, Google
  • Responsive design - works on mobile devices
  • Media in comments - images (up to 2MB), YouTube videos
  • Moderation - admin panel for managing comments
  • Anti-spam - built-in protection

Implementation

Step 1: Registration

  1. Create an account on disqus.com
  2. Create a new site
  3. Copy your shortname

Step 2: JavaScript Code

Paste the following code before closing </body>:

<div id="disqus_thread"></div>
<script>
    var disqus_shortname = 'YOUR_SHORTNAME';

    (function() {
        var dsq = document.createElement('script');
        dsq.type = 'text/javascript';
        dsq.async = true;
        dsq.src = '//' + disqus_shortname + '.disqus.com/embed.js';
        (document.getElementsByTagName('head')[0] ||
         document.getElementsByTagName('body')[0]).appendChild(dsq);
    })();
</script>

For WordPress

Install the official Disqus Comment System plugin from the WordPress repository.

Where Are Comments Stored?

Comments are stored on Disqus servers, not in your database. This means:

Advantages:

  • No database load
  • Automatic backups
  • Easy migration between sites

Disadvantages:

  • Dependency on external service
  • Data outside your control

Comment Export

Disqus allows exporting comments to XML format, enabling migration to another system.

Summary

Disqus is a good solution for blogs and websites that want to quickly implement a comment system with social media integration. Consider privacy concerns and dependency on an external service.
