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

Calcula Finanças looks production-ready overall, with clean crawl signals. Visible gaps: missing several security headers, incomplete legal pages, and analytics without a consent banner.

Launched on Product Hunt on June 11, 2026. The site is hosted on Amazon.com in the United States, with a domain registered 2 days before launch. We've detected 10 technologies on this site, covering affiliate, analytics, build tooling, and CSS frameworks. The stack includes Tailwind CSS, Vite, and Google Analytics.

It's on one of the most common stacks we track, shared by 1,481 launches.
