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 11 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.

Slumber covers some of the launch checklist, with complete legal pages and a thorough launch checklist. Main gaps: missing several security headers, no robots.txt or sitemap, and incomplete email security.

Launched on Product Hunt on July 2, 2026. The site is hosted on GitHub Pages and served through Fastly, with a domain registered 1 week before launch. Our crawler found 8 technologies on this site, covering analytics, CDN, developer tools, and DNS providers. The stack includes Fastly, GitHub Pages, and GoatCounter.

It's also on one of the most common stacks we track, shared by 2,670 launches.
