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

The Calculators has the basics covered well, with complete legal pages and clean crawl signals. What needs work: missing several security headers and no email security records.

Launched on Product Hunt on June 12, 2026. The site is hosted on Hostinger International Limited in Germany, with a domain registered 4 months before launch. Our crawler found 6 technologies on this site, covering CSS frameworks, web fonts, hosting, and icon font. The stack includes Tailwind CSS, Google Fonts, and Hostinger.

Notably, it's running the same core stack as 121 other launches.
