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

Yomty is largely in shape, with complete legal pages, a thorough launch checklist, and clean crawl signals. What needs work: missing several security headers and incomplete email security.

Launched on Product Hunt on June 19, 2026. The site is hosted on GMO Internet in Japan, with a domain registered in 2023. The crawl picked up 6 technologies on this site, covering analytics, consent tooling, DNS providers, and business email. The stack includes Google, Cloudflare DNS, and Google Analytics.
