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 11 June 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.

Shelf Republic has the basics covered well, with a thorough launch checklist, fast page loads, and clean crawl signals. Main gaps: missing several security headers, incomplete legal pages, and incomplete email security.

Launched on Product Hunt on June 11, 2026. The site is hosted on Vercel, with a domain registered 1 week before launch. Our crawler found 8 technologies on this site, covering CSS frameworks, DNS providers, email forwarding, and transactional email. The stack includes Next.js, React, and Tailwind CSS.

It's also on one of the most common stacks we track, shared by 15,005 launches.
