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 22 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.

MailShot is missing several launch fundamentals. Main gaps: missing several security headers, incomplete legal pages, and no robots.txt or sitemap.

Launched on Product Hunt on June 22, 2026. The site is hosted on Vercel. Our crawler found 5 technologies on this site, covering CSS frameworks, developer tools, hosting, and security. The stack includes Tailwind CSS, HSTS, and shadcn/ui.

It's also on one of the most common stacks we track, shared by 3,367 launches.
