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 13 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.

Tethr covers some of the launch checklist, with complete legal pages and fast page loads. Main gaps: missing several security headers, no robots.txt or sitemap, and no email security records.

Launched on Product Hunt on June 13, 2026. The site is served through Cloudflare. Our crawler found 7 technologies on this site, covering analytics, auth, baas, and CDN. The stack includes Google Sign-In, Cloudflare, and Cloudflare Web Analytics.

SignalPoints
AI palette signals +5

This score is based on structural patterns and is not definitive. Many legitimate sites may trigger signals, and AI-built sites may go undetected. It should be treated as an indicator, not a verdict.
