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 24 June 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.
Build A Harness covers some of the launch checklist, with a thorough launch checklist, fast page loads, and clean crawl signals. What needs work: missing several security headers, incomplete legal pages, and tracking cookies set before any opt-in.
Launched on Hacker News on June 24, 2026. The site is hosted on GitHub Pages and served through Cloudflare, with a domain registered 2 days before launch. Our crawler found 9 technologies on this site, covering CDN, analytics, DNS providers, and web fonts. The stack includes Cloudflare, Cloudflare DNS, and Fastly.
It's also running the same core stack as 2,669 other launches.

Vibe Score Breakdown How?
| Signal | Points |
