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

freecalctools.net ships with the basics, with a thorough launch checklist and clean crawl signals. Worth fixing first: missing several security headers, incomplete legal pages, and tracking cookies set before any opt-in.

Launched on Product Hunt on June 23, 2026. The site is hosted on Hostinger International Limited in Lithuania, with a domain registered 3 weeks before launch. We've detected 16 technologies on this site, covering wordpress plugin, servers, analytics, and CMS. The stack includes WordPress, Astra, and Contact Form 7.

It's running the same core stack as 917 other launches.
