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 6 June 2026; the live site may have changed since.

Attendance Calculator looks production-ready overall, with a thorough launch checklist and clean crawl signals. Main gaps: missing several security headers, incomplete legal pages, and incomplete email security.

We've detected 8 technologies on this site, covering CSS frameworks, DNS providers, business email, and web fonts. The stack includes Tailwind CSS, cdnjs, and Font Awesome.
