Own this Launch?

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

SakuSakuBiz covers some of the launch checklist. Main gaps: no Permissions-Policy, incomplete legal pages, and no robots.txt or sitemap.

Launched on Product Hunt on June 5, 2026. The site is hosted on Oracle Corporation in Sweden, with a domain registered in 2025. Our crawler found 5 technologies on this site, covering DNS providers, business email, security, and seo. The stack includes Apache, Google Search Console, and HSTS.

Notably, it's more locked down than the typical Product Hunt launch.
