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

CoreConverter has the basics covered well, with a thorough launch checklist and clean crawl signals. What needs work: missing several security headers, incomplete legal pages, and incomplete email security.

Launched on Product Hunt on June 23, 2026. The site is hosted on Hetzner Online GmbH in Germany, with a domain registered 2 weeks before launch. Our crawler found 8 technologies on this site, covering CSS frameworks, business email, frameworks, and javascript library. The stack includes Next.js, React, and Tailwind CSS.

Notably, it's running the same core stack as 2,902 other launches.
