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 19 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.
CalcVault — Free Online Calculators (Loans, PKR & More) scores highly overall, with complete legal pages, a thorough launch checklist, and clean crawl signals. Main gaps: missing several security headers, tracking cookies set before any opt-in, and incomplete email security.
The site is served through Cloudflare, with a domain registered 3 weeks before launch. Our crawler found 16 technologies on this site, covering advertising, analytics, CDN, and CSS frameworks. The stack includes Tailwind CSS, Cloudflare, and Cloudflare DNS.
