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 30 August 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.

MyPDF4U is largely in shape, with complete legal pages, a thorough launch checklist, and well-configured email security. What needs work: missing several security headers.

Launched on Product Hunt on August 30, 2026. The site is hosted on Vercel, with a domain registered 6 days before launch. The crawl picked up 12 technologies on this site, covering ui library, CSS frameworks, developer tools, and DNS providers. The stack includes Tailwind CSS, TanStack Start, and GoDaddy DNS.

For context, it's running the same core stack as 199 other launches.
