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

Kyohansha is partway there. Main gaps: no Content-Security-Policy, incomplete legal pages, and no sitemap.

Launched on Product Hunt on April 22, 2026. The site is hosted on Vercel and served through Cloudflare. The crawl picked up 8 technologies on this site, covering CDN, CSS frameworks, DNS providers, and frameworks. The stack includes Next.js, React, and Tailwind CSS.

For context, it's on one of the most common stacks we track, shared by 10,672 launches and more locked down than the typical Product Hunt launch.
