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 2 September 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.
Quilpen scores highly overall, with complete legal pages, a complete set of security headers, and a thorough launch checklist. Main gaps: no email security records.
Launched on Product Hunt on September 2, 2026. The site is served through Cloudflare, with a domain registered 4 months before launch. The crawl picked up 13 technologies on this site, covering ui library, auth, CDN, and CSS frameworks. The stack includes Auth.js, Next.js, and React.
For context, it's on one of the most common stacks we track, shared by 5,830 launches and more locked down than the typical Product Hunt launch.
