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 25 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.
duo·reader — split view for long documents looks production-ready overall, with complete legal pages and a thorough launch checklist. Main gaps: missing several security headers, no sitemap, and incomplete email security.
The site is served through Cloudflare, with a domain registered 2 days before launch. We've detected 8 technologies on this site, covering directory, CDN, DNS providers, and email forwarding. The stack includes Cloudflare, Cloudflare Bot Management, and Cloudflare DNS.

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.
