Two-line embed

Add a <div> and a <script> tag. Commex does the rest — auto-detects your page, loads comments instantly.

Rich reactions

10 built-in emoji reactions plus custom org-specific ones. Upvoting, downvoting, and per-page reactions too.

Threaded replies

Full nested comment threads with @mentions, notifications, and smart depth limiting to keep conversations readable.

🎞️

GIFs & media

Integrated Tenor GIF search, image uploads, and rich text with markdown formatting built right into the comment box.

🛡️

Moderation tools

Pin comments, flag spam, ban words, approve-before-show mode, and full moderation controls for org admins.

🎨

Fully customizable

Custom accent colors, per-org branding, feature toggles, and domain allowlisting to match your site perfectly.
