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 16 July 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.

Pastehex is missing several launch fundamentals. Main gaps: missing several security headers, incomplete legal pages, and no sitemap.

Launched on Hacker News on July 16, 2026. The site is hosted on Fly.io, with a domain registered the day of launch. Our crawler found 9 technologies on this site, covering CSS frameworks, developer tools, DNS providers, and web fonts. The stack includes SolidJS, Tailwind CSS, and TanStack Start.

It's also one of only 8 launches we've crawled running SolidJS.

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.
