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 10 April 2026; the live site may have changed since.

Intent: Business Calendar looks production-ready overall, with a thorough launch checklist, fast page loads, and clean crawl signals. What needs work: missing several security headers, incomplete legal pages, and tracking cookies set before any opt-in.

Launched on Product Hunt on April 4, 2026. The site is hosted on Vercel, with a domain registered 2 weeks before launch. We've detected 6 technologies on this site, covering analytics, developer tools, DNS providers, and web fonts. The stack includes Google Analytics, Google Fonts, and HSTS.

It's running the same core stack as 2,955 other launches.

This score is based on structural patterns and is not definitive. Many legitimate sites may trigger signals, and AI-built sites may go undetected. It should be treated as an indicator, not a verdict.
