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 5 July 2026; the live site may have changed since.
Pennen is largely in shape, with complete legal pages, a thorough launch checklist, and clean crawl signals. Visible gaps: missing several security headers and incomplete email security.
Launched on Product Hunt on July 5, 2026. The site is hosted on Netlify and served through Cloudflare, with a domain registered 5 months before launch. The crawl picked up 6 technologies on this site, covering security, CDN, directory, and hosting. The stack includes Cloudflare, Cloudflare Bot Management, and Google Search Console.
For context, it's on one of the most common stacks we track, shared by 1,400 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.
