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 22 April 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.
PDFHUB24 scores highly overall, with complete legal pages, a complete set of security headers, and a thorough launch checklist. Main gaps: incomplete email security.
Launched on Product Hunt on April 22, 2026. The site is hosted on Railway and served through Cloudflare, with a domain registered 4 months before launch. We've detected 15 technologies on this site, covering AI builders, analytics, APIs, and backend framework. The stack includes Tailwind CSS, CloudConvert, and Cloudflare.
It's on one of the most common stacks we track, shared by 343 launches and more locked down than the typical Product Hunt launch.
