Own this Launch?

StackScope is a free public catalogue of indie launches. We find launches on Product Hunt, Hacker News and similar feeds, then crawl each site to detect its tech stack and score 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.

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 3 technologies on this site, covering DNS providers, web fonts, and package cdn. The stack includes Google Fonts, jsDelivr, and UDAG.
