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

CorDx Tyfast Flu A+B Rapid Antigen Test has the basics covered well, with complete legal pages, a thorough launch checklist, and clean crawl signals. Visible gaps: missing several security headers, tracking cookies set before any opt-in, and incomplete email security.

Launched on Product Hunt on April 4, 2026. The site is hosted on Hostinger and served through Cloudflare, with a domain registered in 2021. Our crawler found 15 technologies on this site, covering analytics, servers, CDN, and CMS. The stack includes Osclass, cdnjs, and Cloudflare.

It's also one of only 5 launches we've crawled running Osclass.
