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 18 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.

Invoice-api.xhub ships with the launch fundamentals in place, with complete legal pages, a thorough launch checklist, and clean crawl signals. Worth fixing first: no Content-Security-Policy and incomplete email security.

Launched on PeerPush on May 18, 2026. The site is hosted on Vercel. We've detected 9 technologies on this site, covering analytics, consent tooling, CSS frameworks, and frameworks. The stack includes Google, Next.js, and React.

It's running the same core stack as 14,963 other launches and tighter on security headers than most PeerPush launches.
