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 16 July 2026; the live site may have changed since.
SuperCali scores highly overall, with complete legal pages, a thorough launch checklist, and clean crawl signals. Visible gaps: no Content-Security-Policy and incomplete email security.
Launched on Product Hunt on July 16, 2026. The site is served through Cloudflare, with a domain registered 4 months before launch. Our crawler found 9 technologies on this site, covering CDN, CSS frameworks, DNS providers, and email forwarding. The stack includes Next.js, React, and Tailwind CSS.
It's also on one of the most common stacks we track, shared by 3,809 launches and more locked down than the typical Product Hunt launch.
