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 May 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.

Sustalium ships with the launch fundamentals in place, with complete legal pages, a complete set of security headers, and a thorough launch checklist.

Launched on Product Hunt on May 11, 2026. The site is hosted on Google Cloud, with a domain registered 5 months before launch. Our crawler found 11 technologies on this site, covering analytics, consent tooling, DNS providers, and business email. The stack includes CookieScript, Google Analytics, and Google Cloud.

It's also running the same core stack as 313 other launches and tighter on security headers than most Product Hunt launches.
