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 6 May 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.
InstantBook has the basics covered well, with complete legal pages. Worth fixing first: no Content-Security-Policy, no robots.txt or sitemap, and tracking cookies set before any opt-in.
Launched on Product Hunt on May 6, 2026. The site is hosted on Vercel, with a domain registered 4 weeks before launch. Our crawler found 12 technologies on this site, covering transactional email, analytics, CSS frameworks, and DNS providers. The stack includes Next.js, React, and Tailwind CSS.
It's also running the same core stack as 14,963 other launches and tighter on security headers than most Product Hunt launches.
