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 15 April 2026; the live site may have changed since.

ClearCalc ships with the launch fundamentals in place, with complete legal pages, a thorough launch checklist, and clean crawl signals. What needs work: missing Permissions-Policy and Content-Security-Policy and incomplete email security.

Launched on Product Hunt on April 15, 2026. The site is hosted on Vercel, with a domain registered 4 days before launch. We've detected 14 technologies on this site, covering advertising, affiliate, analytics, and consent tooling. The stack includes Google Funding Choices, Next.js, and React.

It's running the same core stack as 2,295 other launches and tighter on security headers than most Product Hunt launches.
