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 8 May 2026; the live site may have changed since.
GPA Calculator ships with the launch fundamentals in place, with complete legal pages and clean crawl signals. What needs work: no Content-Security-Policy, tracking cookies set before any opt-in, and incomplete email security.
Launched on Product Hunt on May 8, 2026. The site is hosted on Vercel, with a domain registered 4 days before launch. Our crawler found 11 technologies on this site, covering analytics, CSS frameworks, DNS providers, and business email. The stack includes Next.js, React, and Tailwind CSS.
It's also running the same core stack as 14,130 other launches and tighter on security headers than most Product Hunt launches.
