Cusdis

Comments for small sites without Disqus's baggage: Cusdis is a lightweight, privacy-first, open-source comment system for embedding under blog posts and articles. The embedded JavaScript SDK is about 5 KB gzipped (Disqus is roughly 24 KB), sets no cookies, runs no tracking, and does not require readers to create an account or sign in before commenting. Integration is two lines: a container div with your app ID and an async script tag, with ready-made adapters for common frameworks and static site generators. Moderation is approval-based - new comments stay hidden until you approve them from the dashboard, and email notifications include a Quick Approve link that approves or replies to a comment from your phone without logging in. A webhook fires on every new comment for integrations like Telegram notifications. The widget ships with built-in i18n and dark mode. The stack is TypeScript and Next.js with a Prisma data layer, deployable via Docker with PostgreSQL. Deliberately minimalist: no ads, no reader profiling, and your comment data lives in your own database.

Benefits

  • No Ads, No Tracking, No Cookies
  • Disqus monetizes your readers with ads and data collection. Cusdis embeds nothing but the comment widget - zero cookies and zero third-party requests.
  • Readers Comment Without Accounts
  • No sign-in wall means lower friction and more comments; a name and message is all a reader needs.
  • One-Fifth the Page Weight
  • At ~5 KB gzipped versus Disqus's ~24 KB, the widget barely registers in page load metrics - fitting for performance-tuned static blogs.
  • Moderate from Your Inbox
  • Approval-based moderation with Quick Approve links in notification emails means comment review happens on your phone, not in a dashboard.
