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 10 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.

YT1s: YouTube video downloader is largely in shape, with complete legal pages, a thorough launch checklist, and fast page loads. Worth fixing first: missing several security headers, tracking cookies set before any opt-in, and no email security records.

Launched on Product Hunt on June 10, 2026. The site is served through Cloudflare, with a domain registered 4 months before launch. The crawl picked up 6 technologies on this site, covering analytics, CDN, DNS providers, and protocol. The stack includes Cloudflare, Cloudflare DNS, and Google Analytics.
