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.

Costyfood ships with the basics, with a thorough launch checklist and clean crawl signals. What needs work: missing several security headers, incomplete legal pages, and analytics without a consent banner.

Launched on Product Hunt on June 11, 2026. The site is hosted on Amazon.com in the United States, with a domain registered 8 weeks before launch. We've detected 9 technologies on this site, covering analytics, CSS frameworks, DNS providers, and transactional email. The stack includes Next.js, React, and Tailwind CSS.

It's running the same core stack as 7,238 other launches.
