Own this Launch?

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 19 August 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.

DupEase · 易查重 is largely in shape, with a thorough launch checklist, fast page loads, and clean crawl signals. Worth fixing first: no Strict-Transport-Security, incomplete legal pages, and incomplete email security.

The site is served through Cloudflare, with a domain registered 6 weeks before launch. The crawl picked up 6 technologies on this site, covering analytics, CDN, developer tools, and DNS providers. The stack includes Cloudflare, Cloudflare DNS, and Cloudflare Email Routing.

For context, it's tighter on security headers than most StackScope Discovery launches.
