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 6 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.

Brianguthrie is missing several launch fundamentals. Visible gaps: missing several security headers, incomplete legal pages, and no robots.txt.

Launched on Hacker News on May 6, 2026. The site is hosted on GitHub Pages and served through Fastly, with a domain registered in 2004. Our crawler found 7 technologies on this site, covering analytics, CDN, CSS frameworks, and DNS providers. The stack includes Tailwind CSS, DNSimple, and Fastly.

It's also on one of the most common stacks we track, shared by 301 launches.
