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 7 July 2026; the live site may have changed since.
CalcDeck has the basics covered well, with a thorough launch checklist and clean crawl signals. Main gaps: missing several security headers, incomplete legal pages, and tracking cookies set before any opt-in.
Launched on Product Hunt on July 7, 2026. The site is hosted on Hostinger, with a domain registered 6 days before launch. Our crawler found 5 technologies on this site, covering analytics, business email, web fonts, and hosting. The stack includes Google Analytics, Google Fonts, and Google Tag Manager.
It's also on one of the most common stacks we track, shared by 795 launches.
