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 27 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.
Calc Labz scores highly overall, with complete legal pages, a complete set of security headers, and a thorough launch checklist. Main gaps: incomplete email security.
Launched on Product Hunt on April 27, 2026. The site is hosted on Vercel, with a domain registered 3 weeks before launch. The crawl picked up 15 technologies on this site, covering package cdn, advertising, analytics, and DNS providers. The stack includes Svelte, cdnjs, and Font Awesome.
For context, it's one of 26 launches on this exact stack and more locked down than the typical Product Hunt launch.

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.
