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

Yomoo: Easy Japanese Reading ships with the launch fundamentals in place, with a thorough launch checklist and clean crawl signals. Worth fixing first: missing Content-Security-Policy and Strict-Transport-Security, incomplete legal pages, and incomplete email security.

Launched on PeerPush on June 30, 2026. The site is served through Cloudflare, with a domain registered in 2023. We've detected 9 technologies on this site, covering analytics, CDN, DNS providers, and business email. The stack includes Cloudflare, Cloudflare DNS, and Cloudflare Web Analytics.

It's tighter on security headers than most PeerPush launches.
