Own this Launch?

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

SigmaExacta looks production-ready overall, with clean crawl signals. What needs work: no Permissions-Policy, incomplete legal pages, and tracking cookies set before any opt-in.

Launched on Product Hunt on April 20, 2026. The site is hosted on Netlify, with a domain registered 10 months before launch. We've detected 13 technologies on this site, covering analytics, seo, DNS providers, and business email. The stack includes cdnjs, Font Awesome, and Google Analytics.

It's running the same core stack as 1,570 other launches and tighter on security headers than most Product Hunt launches.
