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.

Free Online Calculators is partway there, with a thorough launch checklist and clean crawl signals. Worth fixing first: missing several security headers, incomplete legal pages, and incomplete email security.

Launched on Product Hunt on June 19, 2026. The site is hosted on Hostinger International Limited in Ukraine, with a domain registered 3 months before launch. The crawl picked up 11 technologies on this site, covering advertising, CMS, consent tooling, and business email. The stack includes Google, WordPress, and Google AdSense.

For context, it's running the same core stack as 689 other launches.
