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 6 June 2026; the live site may have changed since.

PassiveKit.com looks production-ready overall, with clean crawl signals. Visible gaps: missing several security headers, incomplete legal pages, and analytics without a consent banner.

Launched on Product Hunt on June 6, 2026. The site is hosted on Hostinger International Limited in Germany, with a domain registered 10 weeks before launch. We've detected 9 technologies on this site, covering servers, analytics, CMS, and hosting. The stack includes WordPress, Google Analytics, and Google Search Console.
