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 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.

Crux ships with the basics, with complete legal pages. What needs work: missing several security headers, no robots.txt or sitemap, and incomplete email security.

Launched on Product Hunt on May 5, 2026. The site is hosted on GitHub Pages and served through Fastly. We've detected 5 technologies on this site, covering CDN, DNS providers, business email, and web fonts. The stack includes Fastly, GitHub Pages, and Google Domains DNS.

It's running the same core stack as 2,682 other launches.
