Show HN: Brain Frog – Can you be random enough for 11 lines of JavaScript?

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

Brain Frog covers some of the launch checklist. What needs work: missing Permissions-Policy and Content-Security-Policy, incomplete legal pages, and no sitemap.

Launched on Hacker News on June 19, 2026. The site is hosted on Cloudflare in the United States, with a domain registered the day of launch. Our crawler found 4 technologies on this site, covering CDN, DNS providers, protocol, and security. The stack includes Cloudflare, Cloudflare DNS, and HSTS.

Notably, it's tighter on security headers than most Hacker News 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.
