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.
