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

CoBlack ships with the launch fundamentals in place, with complete legal pages, a complete set of security headers, and a thorough launch checklist. Worth fixing first: incomplete email security.

Launched on Product Hunt on July 20, 2026. The site is served through Cloudflare, with a domain registered in 2017. We've detected 9 technologies on this site, covering analytics, CDN, DNS providers, and business email. The stack includes Cloudflare, Cloudflare DNS, and GoatCounter.

It's tighter on security headers than most Product Hunt launches.
