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 4 June 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.
InstaPDFKit has the basics covered well, with a thorough launch checklist, fast page loads, and clean crawl signals. What needs work: no Permissions-Policy, incomplete legal pages, and no email security records.
Launched on Product Hunt on June 4, 2026. The site is hosted on Vercel, with a domain registered 4 days before launch. Our crawler found 17 technologies on this site, covering advertising, analytics, baas, and consent tooling. The stack includes Google Funding Choices, Tailwind CSS, and Google Ads.
It's also running the same core stack as 3,366 other launches and tighter on security headers than most Product Hunt 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.
