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 10 April 2026; the live site may have changed since.
Calcflux scores highly overall, with complete legal pages, a complete set of security headers, and a thorough launch checklist. Visible gaps: no email security records.
Launched on Product Hunt on April 7, 2026. The site is hosted on Vercel, with a domain registered 4 weeks before launch. Our crawler found 15 technologies on this site, covering advertising, analytics, captcha, and collaboration. The stack includes Next.js, React, and Tailwind CSS.
It's also on one of the most common stacks we track, shared by 10,672 launches and more locked down than the typical Product Hunt launch.
