As regular readers might know, Carnival is the service we wrote to add comments to this very blog. Today, we’re excited to announce that it’s officially ready for you to use to add comments to your own sites.
Carnival is a paid service, but still completely open source. That means you can see how it works, track progress, report bugs, and request features directly in GitHub. We feel that the transparency of an open process is extremely valuable and doesn’t mean we can’t also make the project sustainable.
In addition to adding comment threads to your site, Carnival also sends email notifications on replies, and provides an RSS feed of recent comments useful for integrations through tools like Zapier and IFTTT.

Add that to any page to enable comments powered by Carnival.
