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 29 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.
PDFem scores highly overall, with complete legal pages, a thorough launch checklist, and clean crawl signals. Visible gaps: no Permissions-Policy and incomplete email security.
Launched on Product Hunt on May 29, 2026. The site is served through Cloudflare, with a domain registered 1 day before launch. The crawl picked up 10 technologies on this site, covering advertising, analytics, CDN, and consent tooling. The stack includes Google, Cloudflare, and Cloudflare DNS.
For context, it's more locked down than the typical Product Hunt launch.

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.
