Reactions allow your readers to give an initial response to an article or question, and see how the rest of the community feels about it before getting into the details in the comments.

How to enable reactions 

If you’re the moderator of your Disqus forum, you can enable reactions from your Disqus admin in your Admin > Settings > Reactions.

Configure images and text

Reactions can be configured with emoji images and text, or text only. Select your desired emoji from the “Image” dropdown menus for each Reaction and edit the text in the “Description” field.

To add or remove a Reaction, use the “Remove” or “+ Add reaction” buttons. Keep in mind that you can save a minimum of 2 Reactions and a maximum of 6.

Preview before saving

Use the “Show Preview” button to expand a mock discussion that includes the customization you have made. This is how the Reactions feature will appear on your website. Immediately  after clicking “Save”. You can make further customizations to the feature if you are not happy with the current preview.

After clicking “Save”, you will be presented with a popup that explains how the changes you have made to the Reactions feature will only apply to new articles. If you would like to apply your changes to older articles that previously had Reactions enabled, toggle the checkbox shown below.

Custom Reactions

**Access to Custom Reactions is available as part of our Pro and Business subscription plans. You may subscribe to Pro from your Subscription page, or can request information on the Business plan from one of our account managers here**

Setting Up Custom Reactions

Custom Reactions may be set up from your admin panel, and will appear below the “Configure and enable Reactions” section of your Reactions Settings page.

New Custom Reactions may be created by uploading image files from your computer. You may use images that are in the JPEG, PNG, or GIF formats (including animated GIFs). When choosing images for your Custom Reactions, please ensure that the files are smaller than 5mb.

To upload a custom reaction Image, simply click the Plus button, select your images, and hit open. After these have been successfully uploaded, they may be selected in the Reactions dropdown. 

When selecting images to use, please note that all uploaded images will be resized to a 1:1 ratio. 

When uploading Custom Reaction images, you may select multiple gifs/images to be uploaded at the same time. Images cannot be added twice, as our system will automatically prevent duplicates.

Once uploaded, you may select a new custom image as you would any regular Reaction image in the Reactions drop-down. 

Deleting Customized Reactions

To delete custom images, select the images you want to delete, and then click the delete button. This will remove images that you have uploaded.

Please note that you are only able to delete custom images that are not currently being used by a Reaction, and images will need to be removed from the Reactions template (saved or unsaved) prior to removal. 

Deleted images will continue to show in the Reactions section for threads created during their use, even if one of these Reaction images is later deleted. 

Closing Reactions for specific discussions

Note: When Reactions are enabled, they will appear in new article discussions only. Existing article threads will not display the Reactions widget.

To disable Reactions on individual discussions, visit the article on your website you would like to edit and toggle the “Remove Reactions” dropdown option found in the top-right dropdown the embed.


The Reactions feature is optimized to look great on mobile so that readers of your site can share what they think from any device.


Does a reader have to be logged in to Disqus in to share their Reaction?

No, logged out readers can still click or tap on the Reaction responses and will be counted alongside logged in commenters. This helps increase engagement on your site from logged out readers.

Can I enable reactions to appear in all existing articles when turning on Reactions?

No, Reactions will only appear on newly published articles after you enable Reactions.
