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 12 April 2026; the live site may have changed since.

Davidcapper still has work before launch. Visible gaps: missing several security headers, incomplete legal pages, and no robots.txt or sitemap.

Launched on Hacker News on April 5, 2026. The site is hosted on GitHub Pages and served through Fastly, with a domain registered in 2020. The crawl picked up 7 technologies on this site, covering analytics, CDN, DNS providers, and email forwarding. The stack includes Jekyll, Fastly, and GitHub Pages.

For context, it's one of only 48 launches we've crawled running Jekyll.

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.
