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 11 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.
Harmony Mapper still has work before launch. Visible gaps: missing several security headers, incomplete legal pages, and no sitemap.
Launched on Product Hunt on May 11, 2026. The site is hosted on Vercel, with a domain registered 1 week before launch. The crawl picked up 6 technologies on this site, covering hosting, transactional email, web fonts, and meta-frameworks. The stack includes SvelteKit, Google Fonts, and HSTS.
For context, it's one of only 3 launches we've crawled running Web4U.

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.
