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 15 April 2026; the live site may have changed since.

StockFit API has the basics covered well, with complete legal pages, a thorough launch checklist, and fast page loads. What needs work: missing several security headers, tracking cookies set before any opt-in, and incomplete email security.

Launched on Hacker News on April 15, 2026. The site is hosted on Vercel. Our crawler found 9 technologies on this site, covering advertising, analytics, CSS frameworks, and DNS providers. The stack includes Next.js, React, and Tailwind CSS.

It's also running the same core stack as 10,671 other launches.

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.
