Added August 16, 2026 · Last analysed August 26, 2026 · via StackScope Discovery · also on Product Hunt

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 26 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.

Calciverse — Free Online Calculators, Financial & Utility Tools (Calciverse.in) is largely in shape, with complete legal pages, a thorough launch checklist, and clean crawl signals. Visible gaps: missing several security headers and no email security records.

The site is hosted on Vercel, with a domain registered the day of launch. The crawl picked up 11 technologies on this site, covering advertising, analytics, consent tooling, and CSS frameworks. The stack includes Google Funding Choices, Tailwind CSS, and Google AdSense.

For context, it's on one of the most common stacks we track, shared by 3,367 launches.
