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 17 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.

Mailercloud Email Verifier scores highly overall, with complete legal pages, a complete set of security headers, and a thorough launch checklist. Visible gaps: incomplete email security.

Launched on Product Hunt on July 17, 2026. The site is served through Cloudflare, with a domain registered in 2011. The crawl picked up 31 technologies on this site, covering analytics, seo, advertising, and email marketing. The stack includes CookieYes, Nuxt, and Tailwind CSS.

For context, it's on one of the most common stacks we track, shared by 277 launches and more locked down than the typical Product Hunt launch.
