Cusdis is a tiny open-source comment widget, a few kilobytes on the page, built for small and static sites. It sets no cookies and asks readers for no sign-in to leave a comment. You can self-host it or use the project’s hosted option, and you moderate from a simple dashboard where comments stay hidden until you approve them.

Our take
Cusdis is the minimalist choice when you want a comment box that respects readers and barely touches the page. It loads no cookies, asks for no login, and gives you a hosted option if you would rather not run a server at all, which is the gap Remark42 leaves open. The honest catch is that minimal cuts both ways: moderation and features are thin, there is no built-in spam filter, and it is a small project, so you are trusting a lean codebase and approving comments by hand. Pick Cusdis for a low-traffic personal site where simplicity and a clean reader experience matter most. For a busier site that needs stronger moderation, a fuller engine like Isso or Remark42 will serve you longer.
