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 3 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.

Languages ships with the basics, with well-configured email security. Worth fixing first: no Strict-Transport-Security, incomplete legal pages, and no sitemap.

Launched on Hacker News on May 3, 2026. The site is served through Cloudflare, with a domain registered 7 months before launch. We've detected 2 technologies on this site, covering CDN and protocol. The stack includes Cloudflare and HTTP/3.

It's tighter on security headers than most Hacker News launches.
