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 28 April 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.

Baby Sleep Tools Calculators looks production-ready overall, with complete legal pages, a thorough launch checklist, and clean crawl signals. Worth fixing first: missing several security headers, tracking cookies set before any opt-in, and no email security records.

Launched on Product Hunt on April 28, 2026. The site is hosted on Vercel, with a domain registered the day of launch. We've detected 11 technologies on this site, covering analytics, baas, CSS frameworks, and developer tools. The stack includes React, Tailwind CSS, and Cloudflare DNS.

It's one of 56 launches on this exact stack.
