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 29 June 2026; the live site may have changed since.

USCalcHub.com covers some of the launch checklist, with complete legal pages and clean crawl signals. Visible gaps: missing several security headers and incomplete email security.

Launched on Product Hunt on June 29, 2026. The site is hosted on Hetzner Online GmbH in Germany, with a domain registered 8 weeks before launch. Our crawler found 6 technologies on this site, covering advertising, analytics, CSS frameworks, and transactional email. The stack includes Tailwind CSS, Google Ads, and Google Analytics.

It's also on one of the most common stacks we track, shared by 5,216 launches.

This score is based on structural patterns and is not definitive. Many legitimate sites may trigger signals, and AI-built sites may go undetected. It should be treated as an indicator, not a verdict.
