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 31 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.
SightSinger.app looks production-ready overall, with a thorough launch checklist and clean crawl signals. Visible gaps: missing several security headers, placeholder text in the legal pages, and tracking cookies set before any opt-in.
Launched on Product Hunt on May 31, 2026. The site is hosted on Firebase App Hosting and served through Fastly, with a domain registered 4 months before launch. We've detected 17 technologies on this site, covering security, analytics, baas, and CDN. The stack includes Next.js, React, and Brevo.
