Disqus is a free, hosted commenting system you can drop into your Jekyll site. With Disqus, we can add commenting to a blog or other pages in a couple of minutes.


  1. Register your site with Disqus.
  2. Copy the Universal Embed code below

    <div id="disqus_thread"></div>
      var disqus_shortname = '{{ site.disqus_shortname }}';
      var disqus_config = function () {
        this.page.url = "{{ page.url | prepend: site.url }}";
        this.page.identifier = "{{ page.id }}";
      (function() {  // DON'T EDIT BELOW THIS LINE
        var d = document, s = d.createElement('script');
        s.src = '//' + disqus_shortname + '.disqus.com/embed.js';
        s.setAttribute('data-timestamp', +new Date());
        (d.head || d.body).appendChild(s);
    <noscript>Please enable JavaScript to view the <a href="https://disqus.com/?ref_noscript" rel="nofollow">comments powered by Disqus.</a></noscript>
  3. Paste it into your post layout.
  4. Set url to your site’s domain and disqus_shortname to your shortname in _config.yml

    url: http://mysite.com
    disqus_shortname: YOUR_DISQUS_SHORTNAME

Turn off commenting

If we wanted to disable commenting on particular pages we could set comments: false in front matter the surround the Universal Embed code with an if statement:

{% if page.comments != false %}
{% endif %}
