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

CalculatorKaro looks production-ready overall, with a thorough launch checklist and clean crawl signals. What needs work: missing several security headers, incomplete legal pages, and incomplete email security.

Launched on Product Hunt on April 24, 2026. The site is hosted on Hostinger, with a domain registered 2 weeks before launch. We've detected 14 technologies on this site, covering advertising, servers, analytics, and CMS. The stack includes WordPress, Google Ads, and Google AdSense.

It's running the same core stack as 1,156 other launches.
