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 25 July 2026; the live site may have changed since.

Numeros looks production-ready overall, with complete legal pages, a thorough launch checklist, and clean crawl signals. What needs work: missing several security headers, tracking cookies set before any opt-in, and incomplete email security.

Launched on Product Hunt on July 25, 2026. The site is hosted on Google LLC in the United States. We've detected 9 technologies on this site, covering advertising, affiliate, analytics, and CMS. The stack includes Blogger, GoDaddy DNS, and Google Ads.

It's one of 66 launches on this exact stack.
