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 20 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.
PerformSpark looks production-ready overall, with complete legal pages, a thorough launch checklist, and well-configured email security. Visible gaps: missing several security headers and tracking cookies set before any opt-in.
Launched on Product Hunt on June 20, 2026. The site is served through Cloudflare, with a domain registered 6 months before launch. We've detected 20 technologies on this site, covering analytics, security, package cdn, and seo. The stack includes Apollo.io, Bing Webmaster, and Cloudflare.
