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

HVAC system design course has the basics covered well, with clean crawl signals. What needs work: missing Permissions-Policy and Strict-Transport-Security, incomplete legal pages, and tracking cookies set before any opt-in.

Launched on Product Hunt on June 19, 2026. The site is hosted on Hostinger International Limited in Ukraine. Our crawler found 11 technologies on this site, covering analytics, chat widgets, business email, and hosting. The stack includes cdnjs, Font Awesome, and Google Analytics.

Notably, it's running the same core stack as 538 other launches and tighter on security headers than most Product Hunt launches.
