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 26 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.

Compare-lab covers some of the launch checklist, with fast page loads and clean crawl signals. What needs work: missing several security headers, incomplete legal pages, and incomplete email security.

Launched on Hacker News on June 26, 2026. The site is served through Cloudflare. Our crawler found 6 technologies on this site, covering CDN, CSS frameworks, DNS providers, and frameworks. The stack includes Next.js, React, and Tailwind CSS.

It's also running the same core stack as 5,881 other launches.
