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 11 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.

pdf-kompakt ships with the launch fundamentals in place, with a thorough launch checklist, well-configured email security, and fast page loads. Worth fixing first: no Content-Security-Policy, incomplete legal pages, and tracking cookies set before any opt-in.

Launched on Product Hunt on April 11, 2026. The site is served through Cloudflare, with a domain registered 1 week before launch. We've detected 8 technologies on this site, covering analytics, CDN, email marketing, and web fonts. The stack includes Cloudflare, Cloudflare Web Analytics, and Google Analytics.

It's tighter on security headers than most Product Hunt launches.
