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 27 August 2026; the live site may have changed since.

ShelfLife: Social Book Tracker scores highly overall, with complete legal pages, a thorough launch checklist, and clean crawl signals. Main gaps: no Permissions-Policy, tracking cookies set before any opt-in, and incomplete email security.

Launched on Product Hunt on August 27, 2026. The site is hosted on AWS S3 and served through AWS CloudFront, with a domain registered 4 months before launch. The crawl picked up 12 technologies on this site, covering analytics, CDN, cloud, and DNS providers. The stack includes Astro, Amazon Web Services, and AWS CloudFront.

For context, it's one of just 24 launches we've crawled on this exact stack and more locked down than the typical Product Hunt launch.

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.
