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 14 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.

MemoCrow ships with the launch fundamentals in place, with complete legal pages, a complete set of security headers, and a thorough launch checklist. What needs work: incomplete email security.

Launched on Product Hunt on July 14, 2026. The site is hosted on OVH SAS in France, with a domain registered 8 months before launch. Our crawler found 12 technologies on this site, covering frameworks, payments, CSS frameworks, and developer tools. The stack includes Capacitor, Tailwind CSS, and Vue.js.

It's also on a stack we've seen on only 5 launches and tighter on security headers than most Product Hunt launches.
