Add Comments to Webflow Sites

With FastComments, you can easily add live commenting to any Webflow site.

The instructions below are for a simple static site, but they also work for a dynamic one using Webflow Collections.

Note that this tutorial requires a FastComments account. It's recommended that you sign up first and then come back here. You can create an account here.

<div id="fastcomments-widget"></div>
<script>
window.fcConfigs = [{

This code is for the Live Commenting widget. The code for other widgets can be found here.

Domain Errors

You may get an authorization error, like the following:

Domain Configuration Missing

Domain Configuration Missing

This happens because FastComments doesn't know it should allow your account to be used on this domain.

In this case, the fix is simple: just add your site to your FastComments.com account.

Go here to add your site to your account.

Add the domain as shown below:
