StackScope records what new websites are built with, the week they launch. Most we find ourselves, by watching public internet infrastructure for brand-new sites; the rest come from Product Hunt, Hacker News and PeerPush. We crawled this one for its tech stack and scored it for launch readiness: DNS, security headers, SEO basics. This page is what we saw on 16 April 2026; the live site may have changed since.

Every technology below links to its own page: which other new sites launched with it. Vendors and agencies watch those pages with Stackdar and hear about new adopters the week they ship, from £15 a month.

Mdview.io covers some of the launch checklist, with a thorough launch checklist, fast page loads, and clean crawl signals. What needs work: missing several security headers, incomplete legal pages, and no email security records.

Launched on Hacker News on April 15, 2026. The site is hosted on Fly.io and served through Cloudflare. Our crawler found 10 technologies on this site, covering analytics, auth, backend framework, and CDN. The stack includes Clerk, Cloudflare, and Cloudflare Bot Management.

This score is based on structural patterns and is not definitive. Many legitimate sites may trigger signals, and AI-built sites may go undetected. It should be treated as an indicator, not a verdict.
