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 13 April 2026; the live site may have changed since.
CalcKing | Calculator has the basics covered well, with complete legal pages, a thorough launch checklist, and clean crawl signals. Visible gaps: missing several security headers and no email security records.
Launched on Product Hunt on April 2, 2026. The site is hosted on Firebase App Hosting, with a domain registered 3 months before launch. Our crawler found 12 technologies on this site, covering hosting, APIs, CSS frameworks, and DNS providers. The stack includes Next.js, React, and Tailwind CSS.
It's also one of just 5 launches we've crawled on this exact stack.

This score is based on structural patterns and is not definitive. Many legitimate sites may trigger signals, and AI-built sites may go undetected. It should be treated as an indicator, not a verdict.
