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 17 April 2026; the live site may have changed since.

IGCSE Grade Calculator 2026 has the basics covered well, with a thorough launch checklist and clean crawl signals. Visible gaps: missing several security headers, incomplete legal pages, and tracking cookies set before any opt-in.

Launched on Product Hunt on April 17, 2026. The site is hosted on Vercel. Our crawler found 8 technologies on this site, covering advertising, analytics, DNS providers, and web fonts. The stack includes Google Analytics, Google Fonts, and Google Search Console.

It's also on one of the most common stacks we track, shared by 2,956 launches.
