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 July 2026; the live site may have changed since.
Calcrux ships with the launch fundamentals in place, with complete legal pages, a thorough launch checklist, and clean crawl signals. What needs work: no Content-Security-Policy, tracking cookies set before any opt-in, and incomplete email security.
Launched on PeerPush on July 14, 2026. The site is hosted on Vercel, with a domain registered 6 weeks before launch. Our crawler found 17 technologies on this site, covering analytics, directory, CSS frameworks, and DNS providers. The stack includes Next.js, React, and Tailwind CSS.
It's also running the same core stack as 10,280 other launches and tighter on security headers than most PeerPush launches.
