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 9 July 2026; the live site may have changed since.
BlkSeal ships with the launch fundamentals in place, with complete legal pages, fast page loads, and clean crawl signals. What needs work: no Permissions-Policy and incomplete email security.
Launched on Product Hunt on July 9, 2026. The site is hosted on Google Cloud, with a domain registered in 2019. The crawl picked up 17 technologies on this site, covering auth, security, analytics, and communication. The stack includes Google OAuth, Google Sign-In, and cdnjs.
For context, it's running the same core stack as 198 other launches and tighter on security headers than most Product Hunt launches.

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.
