EchoThread is a hosted commenting platform that website owners embed with a single script tag to replace native comment sections or migrate away from Disqus. Comments support threaded replies up to five levels deep, emoji reactions, image attachments, link previews, and text formatting including spoiler tags. An ML spam classifier (Siftfy, built by the same maker) screens incoming comments automatically, and site owners get a moderation dashboard with approve, reject, and filter controls plus reply notifications. EchoThread supports passkey sign-in, OAuth (Google, GitHub), magic-link authentication, and an optional no-account guest commenting mode. The widget is themeable, mobile-first, roughly 37 KB gzipped, and ships setup guides for static site generators (Hugo, Jekyll, Astro, Eleventy, Gatsby, Next.js) and hosted builders (WordPress, Shopify, Wix, Framer, Squarespace, Ghost). It supports English, Korean, and Italian out of the box, offers comment export as JSON/CSV, and imports existing threads from Disqus and WordPress (WXR) exports so sites don't lose prior conversations when switching. Pricing is usage-based on page views, comment volume, and number of sites, with a permanent free Hobby tier for one site.
