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

ALL FREE CALCULATORS looks production-ready overall, with complete legal pages, a thorough launch checklist, and clean crawl signals. Visible gaps: missing several security headers, tracking cookies set before any opt-in, and incomplete email security.

Launched on Product Hunt on June 22, 2026. The site is hosted on Hostinger International Limited in Germany, with a domain registered 2 days before launch. We've detected 8 technologies on this site, covering analytics, CDN, directory, and business email. The stack includes Cloudflare, Cloudflare Bot Management, and Google Analytics.

It's on one of the most common stacks we track, shared by 626 launches.
