jskomment is an open source commenting system that is built on javascript and AJAX.

No support is provided. Pull requests are welcome

I also recommend the great tool ISSO,



Create a folder for the data files:

cd server
mkdir jskomment-data
chmod 777 jskomment-data

Open test.html

Alternatively, add the following snippet in your web page (ensure that JQuery is loaded as well, see test.html)

For page-based commenting:

<script src=""></script>
<script src="jskomment-core.js"></script>
<div class="jskomment"></div>
<script> JSKOMMENT.main(); </script>

How to support Markdown in comments?

You can use any JS markdown library. For instance, with pagedown:

<script type="text/javascript" src="pagedown/Markdown.Converter.js"></script>
<script type="text/javascript" src="pagedown/Markdown.Sanitizer.js"></script>
var converter = new Markdown.Converter();
JSKOMMENT_CONFIG.format_function = function (str) { 
  return converter.makeHtml(str);

How to protect comments with captchas?

You can set up a captcha URL as follow:

JSKOMMENT_CONFIG.captcha_url = '';
JSKOMMENT_CONFIG.authenticate = function(elem) {


Is .htaccess readable by the web server and loaded? Is mod_rewrite loaded?
