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 10 July 2026; the live site may have changed since.
SimpleTaxCalculator is largely in shape, with complete legal pages, a thorough launch checklist, and clean crawl signals. What needs work: missing several security headers, tracking cookies set before any opt-in, and incomplete email security.
Launched on Product Hunt on July 10, 2026. The site is hosted on Loopia, with a domain registered 8 weeks before launch. The crawl picked up 15 technologies on this site, covering directory, analytics, hosting, and CSS frameworks. The stack includes Next.js, React, and Tailwind CSS.
For context, it's a rare Loopia sighting, just 17 in our data.

This score is based on structural patterns and is not definitive. Many legitimate sites may trigger signals, and AI-built sites may go undetected. It should be treated as an indicator, not a verdict.
