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 August 2026; the live site may have changed since.
Subsig has the basics covered well, with complete legal pages, a thorough launch checklist, and fast page loads. Visible gaps: missing several security headers, tracking cookies set before any opt-in, and incomplete email security.
Launched on Product Hunt on August 25, 2026. The site is hosted on Amazon.com in the Netherlands, with a domain registered 9 months before launch. Our crawler found 17 technologies on this site, covering social proof, analytics, advertising, and AI builders. The stack includes AppSumo, Capterra, and DigitalOcean DNS.

This score is based on structural patterns and is not definitive. Many legitimate sites may trigger signals, and AI-built sites may go undetected. It should be treated as an indicator, not a verdict.
