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 July 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.is - Fast YouTube Video Downloader looks production-ready overall, with complete legal pages, a thorough launch checklist, and fast page loads. Visible gaps: missing several security headers, tracking cookies set before any opt-in, and no email security records.

Launched on Product Hunt on July 10, 2026. The site is served through Cloudflare, with a domain registered in 2024. We've detected 4 technologies on this site, covering analytics, CDN, protocol, and tag management. The stack includes Cloudflare, Google Analytics, and Google Tag Manager.
