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 26 June 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.

Endtime-instruments is early-stage. What needs work: missing several security headers, incomplete legal pages, and no robots.txt or sitemap.

Launched on Hacker News on June 26, 2026. The site is hosted on rh-tec Business GmbH in Germany. We've detected 5 technologies on this site, covering DNS providers, business email, web fonts, and javascript library. The stack includes Floating UI, Google Fonts, and jsDelivr.
