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 30 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.
Global Invoice Generator – Create Free Invoices | BillSimply is largely in shape, with complete legal pages, a thorough launch checklist, and clean crawl signals. Visible gaps: missing several security headers, tracking cookies set before any opt-in, and incomplete email security.
The site is served through Fastly. The crawl picked up 13 technologies on this site, covering analytics, baas, CDN, and CSS frameworks. The stack includes Tailwind CSS, Fastly, and Firebase.
