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

PackFitter has the basics covered well, with complete legal pages, a thorough launch checklist, and clean crawl signals. Worth fixing first: missing several security headers and incomplete email security.

Launched on Product Hunt on June 17, 2026. The site is hosted on Amazon.com in the United States, with a domain registered 10 weeks before launch. Our crawler found 8 technologies on this site, covering seo, advertising, analytics, and DNS providers. The stack includes Bing Webmaster, Google Analytics, and Google Search Console.

Notably, it's running the same core stack as 1,416 other launches.
