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.

Shelf Republic has the basics covered well, with a thorough launch checklist, fast page loads, and clean crawl signals. Main gaps: missing several security headers, incomplete legal pages, and incomplete email security.

Launched on Product Hunt on June 11, 2026. The site is hosted on Amazon.com in the United States, with a domain registered 1 week before launch. Our crawler found 8 technologies on this site, covering CSS frameworks, DNS providers, business email, and transactional email. The stack includes Next.js, React, and Tailwind CSS.

Notably, it's on one of the most common stacks we track, shared by 7,239 launches.
