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 14 July 2026; the live site may have changed since.

Cirrus ships with the basics, with complete legal pages. Visible gaps: missing several security headers, no robots.txt or sitemap, and incomplete email security.

Launched on Product Hunt on July 14, 2026. The site is hosted on Vercel, with a domain registered 11 weeks before launch. We've detected 3 technologies on this site, covering developer tools, hosting, and security. The stack includes HSTS, Vercel, and Vite.

It's on one of the most common stacks we track, shared by 2,846 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.
