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 31 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.
SDD Observatory — Tracking spec-driven development in the wild. still has work before launch. Main gaps: missing several security headers, incomplete legal pages, and no robots.txt or sitemap.
The site is hosted on GitHub Pages and served through Fastly, with a domain registered 1 week before launch. The crawl picked up 5 technologies on this site, covering analytics, CDN, DNS providers, and business email. The stack includes Fastly, GitHub Pages, and Mijn Domein DNS.
For context, it's on one of the most common stacks we track, shared by 2,681 launches.

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.
