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 8 August 2026; the live site may have changed since.

Sdsentry is partway there, with a thorough launch checklist, well-configured email security, and clean crawl signals. Worth fixing first: missing several security headers and incomplete legal pages.

Launched on Hacker News on August 8, 2026. The site is hosted on Comcast Cable Communications in the United States, with a domain registered in 2025. The crawl picked up 2 technologies on this site, covering analytics and servers. The stack includes nginx and Umami.

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.
