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 17 August 2026; the live site may have changed since.
Onomanabi ships with the launch fundamentals in place, with complete legal pages, a complete set of security headers, and a thorough launch checklist. What needs work: incomplete email security.
Launched on Product Hunt on August 17, 2026. The site is hosted on OpenNext and served through Cloudflare, with a domain registered in 2017. Our crawler found 9 technologies on this site, covering security, analytics, auth, and CDN. The stack includes Clerk, Next.js, and React.
It's also running the same core stack as 132 other launches and tighter on security headers than most Product Hunt launches.
