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 1 July 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.
CalcVerse covers some of the launch checklist, with a thorough launch checklist and clean crawl signals. Worth fixing first: missing several security headers, incomplete legal pages, and no email security records.
Launched on Product Hunt on July 1, 2026. The site is served through Cloudflare. Our crawler found 14 technologies on this site, covering ui library, advertising, AI builders, and analytics. The stack includes Google Funding Choices, React, and Tailwind CSS.
It's also running the same core stack as 304 other launches.
