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 9 August 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.
Katto — AI Video Clipper | Turn Videos into Viral Shorts ships with the launch fundamentals in place, with complete legal pages, a complete set of security headers, and a thorough launch checklist. Worth fixing first: incomplete email security.
The site is hosted on Railway and served through Cloudflare. Our crawler found 20 technologies on this site, covering analytics, directory, transactional email, and APIs. The stack includes Next.js, React, and Tailwind CSS.
It's also running the same core stack as 596 other launches and tighter on security headers than most StackScope Discovery launches.
