Add a commenting platform to a Svelte app

Happy new year!

I recently relaunched my personal blog at using Svelte (learn why).

Initial feedback was to allow visitors to leave comments and have discussions. I took that feedback and found which looked lightweight enough and straitforward to implement.

What I did:

  1. Sign up at
  2. Create a Svelte component that displays comments

The component is as simple as this (corresponding pull request):

  <script src=""></script>

<h2>Comments, Feedback, Thoughts</h2>
<div id="commento" />
Enter fullscreen mode Exit fullscreen mode


You can style the commenting platform by providing a data-css-override attribute to the script tag, for example:

<script src="" data-css-override=""></script>
Enter fullscreen mode Exit fullscreen mode

Additional configuration options can be found in the documentation.

Are there other alternatives you have experience with? What do you like / dislike about them?

Have you had luck with the automatic spam filtering? I am implementing it now, but it looks like I can freely post spammy comments. Not sure if there's additional steps to take to get the automatic spam moderation going? I am using their cloud service.

Hi, I haven't had an issue with spam yet and also haven't tried it myself. I don't recall reading much in the docs about what is considered spam by their software. It may be worth reaching out to the creator directly.
