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

SuperCalX looks production-ready overall, with complete legal pages, a thorough launch checklist, and clean crawl signals. Worth fixing first: missing several security headers, analytics without a consent banner, and no email security records.

Launched on PeerPush on June 4, 2026. The site is hosted on Hostinger International Limited in Germany, with a domain registered 9 weeks before launch. We've detected 9 technologies on this site, covering analytics, CSS frameworks, frameworks, and hosting. The stack includes React, Tailwind CSS, and Google Analytics.

It's on a stack we've seen on only 9 launches.
