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.

Youtube Thumbnail Downloader covers some of the launch checklist, with complete legal pages and a thorough launch checklist. Worth fixing first: missing several security headers, no robots.txt or sitemap, and tracking cookies set before any opt-in.

Launched on Product Hunt on April 20, 2026. The site is hosted on Vercel, with a domain registered the day of launch. Our crawler found 6 technologies on this site, covering advertising, analytics, DNS providers, and hosting. The stack includes Cloudflare DNS, Google AdSense, and Google Analytics.

It's also running the same core stack as 4,255 other launches.
