Own this Launch?

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 28 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.

Henrypan still has work before launch. Main gaps: missing several security headers, incomplete legal pages, and no robots.txt or sitemap.

Launched on Hacker News on May 28, 2026. The site is hosted on GitHub Pages and served through Fastly, with a domain registered in 2015. The crawl picked up 12 technologies on this site, covering package cdn, analytics, CDN, and CSS frameworks. The stack includes Bootstrap, cdnjs, and Fastly.

For context, it's one of 29 launches on this exact stack.
