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

WhosOff scores highly overall, with complete legal pages, a thorough launch checklist, and well-configured email security. Main gaps: missing Referrer-Policy and Permissions-Policy and tracking cookies set before any opt-in.

Launched on PeerPush on August 1, 2026. The site is hosted on Sota Solutions Ltd. in the United Kingdom, with a domain registered in 2005. We've detected 14 technologies on this site, covering advertising, analytics, security, and auth. The stack includes Google Sign-In, ASP.NET, and Bing Ads.

It's more locked down than the typical PeerPush launch.

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.
