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

CalculBox is largely in shape, with complete legal pages and clean crawl signals. Main gaps: missing several security headers and no email security records.

Launched on Product Hunt on June 5, 2026. The site is hosted on Hostinger International Limited in Germany, with a domain registered 1 week before launch. The crawl picked up 9 technologies on this site, covering advertising, build tooling, consent tooling, and hosting. The stack includes Google Funding Choices, Vite, and Google Ads.

For context, it's one of 46 launches on this exact stack.
