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 3 September 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.

SaveOne — X Video Downloader 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: tracking cookies set before any opt-in and no email security records.

Launched on Product Hunt on September 3, 2026. The site is hosted on Tencent Building in Singapore. Our crawler found 7 technologies on this site, covering analytics, DNS providers, protocol, and security. The stack includes Caddy, DNSPod, and Google Analytics.

It's also tighter on security headers than most Product Hunt launches.
