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 27 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.

SatViewer3D | リアルタイム3D人工衛星・宇宙デブリシミュレーター is partway there, with a thorough launch checklist. Worth fixing first: missing Content-Security-Policy and Strict-Transport-Security, incomplete legal pages, and no robots.txt or sitemap.

The site is served through Cloudflare, with a domain registered 4 days before launch. The crawl picked up 13 technologies on this site, covering package cdn, advertising, analytics, and CDN. The stack includes Google Funding Choices, cdnjs, and CesiumJS.

For context, it's tighter on security headers than most StackScope Discovery launches.
