Client-side library for rendering webmentions from


  1. Copy the JavaScript file (webmention.min.js) from the static/ directory to somewhere on your website

  2. Put a <div id="webmentions"></div> where you want your webmentions to be embedded

  3. Put a <script src="/path/to/webmention.min.js" async></script> somewhere on your page (typically inside <head> but it doesn't really matter), replacing /path/to/ with whatever directory the JavaScript file is in

  4. You'll probably want to add some CSS rules to your stylesheet, in particular:

    #webmentions img { max-height: 1.2em; margin-right: -1ex; }

    See the included webmention.css file for an example.

You can also pass in some arguments, for example:

<script src="/path/to/webmention.min.js" data-id="webmention-container" async></script>

Note that the async isn't strictly necessary but it can speed up apparent page loads.

Accepted arguments (see the source in static/webmention.js for more details):

  • page-url -- use this reference URL instead of the current browser location
  • add-urls -- additional URLs to include, separated by a |
  • id -- use this container ID instead of "webmentions"
  • wordcount -- truncate the reply to this many words (adding an ellipsis to the end of the last word)
  • max-webmentions -- the maximum webmentions to retrieve and render (defaults to 30)
  • prevent-spoofing -- set this to use the incoming mention source URL instead of the declared URL; setting this will disable one form of identity spoofing but will make mentions from webmention bridges (such as or Telegraph) significantly uglier
  • sort-by -- what to sort the responses by; defaults to published time (see the webmention API for possible values)
  • sort-dir -- what order to sort the responses by; defaults to 'up' (ascending).
  • comments-are-reactions -- if set to 'true', displays comment-type responses (replies/mentions/etc.) as being part of the reactions (favorites/bookmarks/etc.) instead of in a separate comment list. Defaults to "false".

Look at the source code itself for more detailed information.
