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 25 June 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.
CalcTrip: offline travel calculator has the basics covered well, with a thorough launch checklist and clean crawl signals. Main gaps: missing several security headers, incomplete legal pages, and no email security records.
Launched on Product Hunt on June 25, 2026. The site is hosted on Vercel, with a domain registered 1 week before launch. Our crawler found 7 technologies on this site, covering analytics, auth, CSS frameworks, and frameworks. The stack includes Auth.js, Next.js, and React.
It's also on one of the most common stacks we track, shared by 14,964 launches.
