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 5 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.
NVIDIA Nemotron 3 Ultra looks production-ready overall, with a thorough launch checklist, well-configured email security, and clean crawl signals. Main gaps: missing several security headers and incomplete legal pages.
Launched on Product Hunt on June 5, 2026. The site is hosted on AWS ALB and served through Akamai, with a domain registered in 1993. We've detected 31 technologies on this site, covering analytics, advertising, tag management, and ai api. The stack includes Next.js, OneTrust, and React.
