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 1 July 2026; the live site may have changed since.

SUMIMOTO 住本 is largely in shape, with complete legal pages, a thorough launch checklist, and clean crawl signals. What needs work: missing several security headers and incomplete email security.

Launched on Product Hunt on July 1, 2026. The site is hosted on AWS S3 and served through AWS CloudFront, with a domain registered 10 weeks before launch. The crawl picked up 11 technologies on this site, covering CDN, cloud, CSS frameworks, and DNS providers. The stack includes Next.js, React, and Tailwind CSS.

For context, it's one of 65 launches on this exact stack.

This score is based on structural patterns and is not definitive. Many legitimate sites may trigger signals, and AI-built sites may go undetected. It should be treated as an indicator, not a verdict.
