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 April 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.
Mailzenio is partway there, with a thorough launch checklist and fast page loads. What needs work: missing several security headers, incomplete legal pages, and no sitemap.
Launched on Product Hunt on April 20, 2026. The site is hosted on Vercel and served through Cloudflare. The crawl picked up 10 technologies on this site, covering analytics, CDN, CSS frameworks, and developer tools. The stack includes Tailwind CSS, Cloudflare, and Cloudflare DNS.
For context, it's running the same core stack as 3,366 other launches.
