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

shieldcn ships with the basics, with a thorough launch checklist and clean crawl signals. Worth fixing first: missing several security headers, incomplete legal pages, and no email security records.

Launched on Product Hunt on April 26, 2026. The site is hosted on Vercel, with a domain registered 3 days before launch. We've detected 8 technologies on this site, covering CSS frameworks, DNS providers, frameworks, and hosting. The stack includes Next.js, React, and Tailwind CSS.

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