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.

My Senpai Japanese Crosswords ships with the launch fundamentals in place, with complete legal pages, a thorough launch checklist, and clean crawl signals. What needs work: missing Content-Security-Policy and Strict-Transport-Security and incomplete email security.

Launched on PeerPush on June 30, 2026. The site is served through Cloudflare, with a domain registered in 2023. The crawl picked up 11 technologies on this site, covering analytics, advertising, CDN, and consent tooling. The stack includes Google, Cloudflare, and Cloudflare DNS.

For context, it's tighter on security headers than most PeerPush launches.
