Cusdis

Cusdis is a comment system designed for websites. It provides a straightforward way for site owners to add a comment section to their pages, similar to services like Disqus, but with a focus on being lightweight and respecting user privacy. You embed a small JavaScript snippet, and Cusdis handles the display and storage of comments. The service promises not to track you or your visitors.

It works by giving you a dashboard to manage comments and several ways to stay notified. You get email alerts for new comments, and those emails contain links to approve or reply to a comment quickly without logging into the admin panel. For developers, Cusdis supports webhooks, letting you connect new comments to other apps like Telegram. A key feature is its size—the core code that loads on your site is only about 5 kilobytes. It also supports multiple languages and has a dark mode. You can use their free cloud service or download the open-source code to host it yourself.

This tool is best for bloggers, especially those using static site generators like Hexo or Docsify, who want a simple, non-intrusive comment system. It's also a solid choice for anyone who dislikes the bloat or tracking of larger commercial comment platforms. The free cloud tier supports one site with 100 comments per month, while a low-cost Pro plan removes those limits. If you need full control, the self-hosted version is free and includes all features.
