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

JC ONE FIX ships with the launch fundamentals in place, with a complete set of security headers, a thorough launch checklist, and clean crawl signals. What needs work: incomplete legal pages and incomplete email security.

Launched on Product Hunt on June 21, 2026. The site is hosted on Amazon.com in the United States, with a domain registered 7 weeks before launch. The crawl picked up 19 technologies on this site, covering hosting, advertising, analytics, and APIs. The stack includes MercadoLibre, Next.js, and React.

For context, it's a rare MercadoLibre sighting, just 3 in our data and tighter on security headers than most Product Hunt launches.
