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 14 June 2026; the live site may have changed since.
Calculora scores well across the board, with complete legal pages and a thorough launch checklist. Visible gaps: no Content-Security-Policy, no robots.txt, and incomplete email security.
Launched on Product Hunt on June 14, 2026. The site is hosted on Namecheap in the United States, with a domain registered 1 week before launch. We've detected 10 technologies on this site, covering consent tooling, CSS frameworks, DNS providers, and business email. The stack includes Google, Next.js, and React.
It's on one of the most common stacks we track, shared by 2,541 launches and more locked down than the typical Product Hunt launch.
