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 19 June 2026; the live site may have changed since.
CalkHub Age Calculator ships with the launch fundamentals in place, with complete legal pages, a complete set of security headers, and a thorough launch checklist. Worth fixing first: incomplete email security.
Launched on Product Hunt on June 19, 2026. The site is hosted on Solid Systems LLC in the United States, with a domain registered 4 weeks before launch. We've detected 12 technologies on this site, covering servers, analytics, APIs, and consent tooling. The stack includes Google, cdnjs, and ExchangeRate-API.
It's a rare HosterSale sighting, just 2 in our data and tighter on security headers than most Product Hunt 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.
