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

Jacked looks production-ready overall, 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 8, 2026. The site is hosted on Contabo Asia Private Limited in Germany. We've detected 7 technologies on this site, covering CMS, CSS frameworks, frameworks, and meta-frameworks. The stack includes Next.js, React, and Sanity.

It's on a stack we've seen on only 8 launches.
