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 10 June 2026; the live site may have changed since.
NihongoHub has the basics covered well, with a complete set of security headers, a thorough launch checklist, and clean crawl signals. Main gaps: incomplete legal pages and incomplete email security.
Launched on Product Hunt on June 10, 2026. The site is hosted on Upstash and served through Cloudflare, with a domain registered 1 week before launch. Our crawler found 17 technologies on this site, covering hosting, package cdn, security, and affiliate. The stack includes Cloudflare, Cloudflare Bot Management, and esm.sh.
It's also one of just 2 launches we've crawled on this exact stack and more locked down than the typical Product Hunt launch.
