Own this Launch?

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 May 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.

Tsurukame Portal still has work before launch. Main gaps: missing several security headers, incomplete legal pages, and no mobile viewport meta tag.

Launched on Product Hunt on May 18, 2026. The site is hosted on Xserver, with a domain registered 4 months before launch. The crawl picked up 5 technologies on this site, covering servers, DNS providers, business email, and hosting. The stack includes nginx, PHP, and Xserver.

For context, it's one of only 34 launches we've crawled running Xserver.
