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 20 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.

PDFLite has the basics covered well, with complete legal pages, a thorough launch checklist, and fast page loads. Visible gaps: missing several security headers and incomplete email security.

Launched on Product Hunt on April 20, 2026. The site is hosted on Vercel. Our crawler found 6 technologies on this site, covering CSS frameworks, developer tools, DNS providers, and email forwarding. The stack includes Tailwind CSS, HSTS, and Namecheap DNS.

It's also on one of the most common stacks we track, shared by 3,377 launches.

This score is based on structural patterns and is not definitive. Many legitimate sites may trigger signals, and AI-built sites may go undetected. It should be treated as an indicator, not a verdict.
