Estimated origin: China
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 18 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.
AI Video Extender – Make Your Videos Longer With AI ships with the launch fundamentals in place, with complete legal pages, a thorough launch checklist, and clean crawl signals. What needs work: missing several security headers and no email security records.
The site is hosted on Vercel and served through Cloudflare, with a domain registered 3 days before launch. The crawl picked up 11 technologies on this site, covering security, analytics, auth, and CDN. The stack includes Clerk, Next.js, and React.
For context, it's running the same core stack as 3,395 other launches.
